Protein is most known for helping us build healthy muscles, but the nutrient offers benefits from head to toe. In particular, protein plays an important role in your brain health, and getting enough of the right ones in your diet can help preserve its function.
Protein is found in every cell of the body including the brain, so it’s important to get enough of it through your diet. That said, of all the protein-rich foods out there, some may benefit your brain more than others.
As for which proteins support your brain the most, we asked a neurologist who told us that you can support your cognitive functioning over the years by adding more fatty fish to your routine. Here’s why.
Nutrients in Fatty Fish
Fatty fish, which includes salmon, black cod, anchovies and bluefin tuna, is high in protein and other nutrients like omega-3 fatty acids (a type of “healthy fat“), making it a nutritious addition to any diet.
For example, a 6-ounce filet of cooked salmon provides 43.2 grams of protein and 246 percent of your Daily Value (DV) for omega-3 fatty acids, per the USDA.
With input from Sharon Stoll, DO, a neurologist and Assistant Professor of Neurology at Yale School of Medicine, we take a deep dive into how eating fatty fish on a regular basis can support healthy cognition.
4 Ways Fatty Fish Benefits Your Brain
1. It’s Rich in DHA
Docosahexaenoic acid, or DHA, is an omega-3 fatty acid that’s commonly associated with brain function, though it also supports a healthy nervous system.
Fish is an ideal source of DHA because it’s readily available. In fact, most of the top food sources of DHA are fatty fish like salmon, tuna and cod, per the USDA. Plant sources of omega-3 fatty acids contain alpha-linolenic acid (ALA), which gets converted to DHA in the body.
Brain tissue may have a preference for DHA in order to keep the brain functioning normally and efficiently, per the Academy of Nutrition and Dietetics.
DHA is especially important for brain development in early childhood, according to the Harvard T.H. Chan School of Public Health. Though its effects are mainly seen in infants, the effects of DHA may also be seen during childhood and adulthood, per a January 2016 review in Nutrients.
In adulthood, low DHA levels have been associated with a higher risk of brain conditions like Alzheimer’s dementia.
2. It Supports Healthy Blood Flow
The body is made up of complex systems, and they don’t work independently from one another. The functioning of your cardiovascular system, for example, can influence your brain health.
“A lot of people don’t realize how interconnected the heart and brain are — you can’t have one without the other,” Stoll says. “Healthy fats are important for brain health because they’re important for the cardiovascular system, which then plays a role in brain functioning.”
Keeping your heart healthy can lower your risk for brain-related health issues like stroke and dementia, according to the CDC. When blood vessels are damaged, your brain can face serious consequences.
“To keep your brain in tip-top shape, we want the blood vessels as open as possible,” Stoll says. That’s where nutrient-dense foods like fatty fish come in.
Protein is an essential nutrient, but animal proteins like pork and some cuts of beef are high in saturated fat, which can raise “bad” cholesterol levels in your blood and clog your arteries. This raises your risk for stroke and heart attack, according to the American Heart Association (AHA).
Fish is considered a more heart-healthy source of protein because it’s not high in saturated fat. In fact, the omega-3 fatty acids may actually improve endothelial function (the lining of your blood vessels), promote vasodilatation (the widening of blood cells) and decrease artery wall stiffening, according to March 2017 research in Nutrition, Metabolism and Cardiovascular Disease.
Keeping your heart healthy, then, translates to better blood flow to your brain.
3. It May Help Lower Triglycerides
There’s a lot left to learn about Alzheimer’s disease, the most common type of dementia, but high triglyceride levels may play a role.
“Eating fatty fish is important for brain health for the same reason it’s important for the heart — it’s associated with lower triglyceride levels,” Stoll says. It’s true: High triglyceride levels in midlife are associated with a higher risk of Alzheimer’s disease later in life, according to a January 2018 study in Neurology.
“Triglycerides are part of what blocks those vessels in the brain and throughout the body, which leads to stroke and heart disease,” Stoll says. There’s strong evidence that omega-3 fatty acids may help lower high triglyceride levels, according to the Mayo Clinic.
4. It May Help Lower Your Risk of Mental Decline
As the number of older adults (age 65+) is steadily increasing, so are rates of dementia and Alzheimer’s disease diagnosis. An estimated 5.8 million people in the United States are affected by the disease, though the number is expected to rise in the coming years, according to the CDC.
Getting more DHA has been associated with a lower risk of these diseases, according to a June 2022 study in Nutrients. Low levels of DHA have also been linked to a higher risk. All that said, more research is needed to determine the direct benefits DHA may have on cognition.
“While the research isn’t conclusive, one thing is definitely for sure — nutrients like omega-3 fatty acids may help protect your brain over time and could slow down the progression of brain diseases,” Stoll says.
WASHINGTON – A new study by Environmental Working Group scientists finds that consumption of just a single serving of freshwater fish per year could be equal to a month of drinking water laced with the “forever chemical” PFOS at high levels that may be harmful.
Researchers calculated that eating one fish in a year equated to ingesting water with PFOS at 48 parts per trillion, or ppt, for one month.
is thought to be a major source of PFAS exposure for Americans.
The findings are a particular issue for communities with environmental justice concerns, whose survival often depends on eating freshwater fish they’ve caught.
EWG found the median amounts of PFAS in freshwater fish were an astounding 280 times greater than forever chemicals detected in some commercially caught and sold fish. The testing data, from the Environmental Protection Agency and Food and Drug Administration, showed that consuming a single meal of freshwater fish could lead to similar PFAS exposure as ingesting store-bought fish every day for a year.
“People who consume freshwater fish, especially those who catch and eat fish regularly, are at risk of alarming levels of PFAS in their bodies,” said David Andrews, Ph.D., EWG senior scientist and one of the study’s lead authors. “Growing up, I went fishing every week and ate those fish. But now when I see fish, all I think about is PFAS contamination.”
The forever chemical found at greatest concentrations in freshwater fish was PFOS, formerly an ingredient in 3M’s Scotchgard, averaging roughly three in four of total PFAS detections.
“These test results are breathtaking,” said Scott Faber, EWG’s senior vice president for government affairs. “Eating one bass is equivalent to drinking PFOS-tainted water for a month.”
Consumption of PFOS-contaminated freshwater fish can cause significant increases in peoples’ blood serum levels of the forever chemical, creating potential health risks. Even infrequent consumption of freshwater fish can raise PFOS levels in the body.
“The extent that PFAS has contaminated fish is staggering”, said Nadia Barbo, a graduate student at Duke University and lead researcher on this project. “There should be a single health protective fish consumption advisory for freshwater fish across the country.”
The researchers analyzed data from more than 500 samples of fish filets collected in the U.S. from 2013 to 2015 under monitoring programs by the EPA, the National Rivers and Streams Assessment and the Great Lakes Human Health Fish Fillet Tissue Study. The median level of total PFAS in fish filets was 9,500 nanograms per kilogram, with a median level of 11,800 nanograms per kilogram in the Great Lakes.
“PFAS contaminate fish across the U.S., with higher levels in the Great Lakes and fish caught in urban areas,” said Tasha Stoiber, Ph.D., an EWG senior scientist and another co-author. “PFAS do not disappear when products are thrown or flushed away. Our research shows that the most common disposal methods may end up leading to further environmental pollution.”
Freshwater fish are an important source of protein for many people, and PFAS contamination threatens those who cannot afford to purchase commercial seafood. Communities that depend on fishing for sustenance and for traditional cultural practices are inordinately harmed. This makes exposure to chemical pollutants in freshwater fish a textbook case of environmental injustice.
“Identifying sources of PFAS exposure is an urgent public health priority,” said Stoiber.
The widespread contamination of fish in rivers and streams across the country further emphasizes the need to end industrial discharges of PFAS.
EWG estimates there may be more than 40,000 industrial polluters of PFAS in the U.S. Tens of thousands of manufacturing facilities, municipal landfills and wastewater treatment plants, airports, and sites where PFAS-containing firefighting foams have been used are potential sources of PFAS discharges into surface water.
This contamination of water has spread PFAS to soil, crops and wildlife, including fish.
“For decades, polluters have dumped as much PFAS as they wanted into our rivers, streams, lakes and bays with impunity. We must turn off the tap of PFAS pollution from industrial discharges, which affect more and more Americans every day,” said EWG’s Faber.
Testing fish for PFAS
The EPA and the FDA test differently to detect PFAS in fish. The EPA uses what’s known as draft Method 1633 to test for up to 40 PFAS compounds in fish tissue, as well as in wastewater, surface water, groundwater, soil, biosolids, sediment and the liquid that forms when waste breaks down in landfills.
National EPA tests show nearly all fish in U.S. rivers and streams are contaminated with PFAS in the parts-per-billion range – even greater than parts per trillion. Although the most recent test results found decreasing PFAS levels, freshwater fish are still contaminated at high levels.
The FDA improved its scientific method to test for 20 different PFAS compounds. Its approach is used to test seafood samples, as well as processed foods. In its 2022 survey of seafood, the FDA found much lower levels of PFAS in seafood from grocery stores. The median levels of total PFAS detected by the EPA were 280 times higher than levels in commercially sold fish tested by the FDA.
PFAS are among the most persistent compounds in existence, contaminating everything from drinking water to food, food packaging and personal care products. PFAS build up in our bodies and never break down in the environment. They are found in the blood of virtually everyone, including newborn babies.
Very low doses of PFAS in drinking water have been linked to suppression of the immune system, including reduced vaccine efficacy, and an increased risk of certain cancers. PFAS are linked with increased cholesterol, reproductive and developmental problems and other health harms.
“The EPA needs to move swiftly to set regulations for the industries most likely to be dumping PFAS into the environment. Downstream communities especially have suffered the consequences of unregulated PFAS discharges for far too long,” added Faber.
- A new study concludes that regular consumption of ultra-processed foods raises a person’s risk of cognitive decline.
- In an earlier study, Australian researchers also reported that ultra-processed foods can negatively impact cognitive functions.
- These foods include packaged snacks and pre-prepared dishes such as pizza and pies.
- These studies line up with previous research that indicates that an unhealthy diet can impair cognitive abilities and raise the risk of dementia-related diseases such as Alzheimer’s.
New research indicates that regularly consuming ultra-processed foods such as hot dogs and frozen pizza can raise your risk of cognitive decline.
In a study Trusted Source published today in the journal JAMA Neurology, researchers looked at more than 10,000 individuals over a median period of 8 years.
They concluded that people whose daily calorie intake is at least 20% from ultra-processed foods had a 25% faster decline in executive functions and a 28% faster rate of overall cognitive impairment.
The researchers noted that if a person’s overall diet quality was high, the effect of ultra-processed foods was less.
“While this is a study of association, not designed to prove cause and effect, there are a number of elements to fortify the proposition that some acceleration in cognitive decay may be attributed to ultra-processed foods,” Dr. David Katz, a specialist in preventive and lifestyle medicine and nutrition, told CNN.
“The sample size is substantial and the follow-up extensive. While short of proof, this is robust enough that we should conclude ultra-processed foods are probably bad for our brains,” he added.
The new findings are in line with another study published in July in the European Journal of Nutrition that also suggested that consuming ultra-processed foods may have a negative impact on cognitive performance in older adults.
The researchers from Australia conducting the study told Healthline they defined ultra-processed foods as those that undergo “several industrial processes that can’t be reproduced at home.”
They noted that these items contain little to no whole foods and typically include flavorings, colorings, emulsifiers, and other cosmetic additives.
Examples include packaged snacks, chocolates, breakfast cereals, and pre-prepared dishes such as pies, pasta, and pizza.
That’s opposed to processed foods that the researchers defined as foods that commonly have added sugar, oil, or salt. The processing is used to increase the durability or enhance the “sensory qualities” of the food. Examples include canned veggies, fruits, legumes, and salted, cured, or smoked meats.
Another study published in the journal Neurology also reported that people who consume high amounts of ultra-processed foods such as sodas, chips, and cookies may have a higher risk of developing dementia.
Using a cross-sectional study, the team of Australian researchers evaluated more than 2,700 participants who were 60 years or older.
The participants were part of the National Health and Nutrition Examination SurveyTrusted Source from 2011 to 2014. Each participant recalled what they ate in a 24-hour period on two nonconsecutive days.
The team used standardized, validated tests, including one that assesses Alzheimer’s disease. They concluded that consuming ultra-processed foods was associated with worse performances in one of the tests among older people who did not have pre-existing diseases.
Researchers told Healthline the findings suggest that decreasing ultra-processed foods may be a way to improve impaired cognition among older adults.
“Research indicates that diets that follow a Mediterranean Diet style, recognized by the high proportion of foods with anti-inflammatory and antioxidant properties, are associated with a reduced risk of age-associated cognitive decline and dementia,” said Barbara Cardoso, Ph.D., lead author of the study and a senior lecturer in nutrition, dietetics, and food at Monash University in Melbourne, Australia.
“Foods consumed as part of these diets include fish, nuts, olive oil, and vegetables,” she said.
Experts say these findings are consistent with what they’ve learned from other studies about diet and dementia.
“There is growing evidence that what we eat can impact our brains as we age and many studies suggest it is best to eat a heart-healthy, balanced diet low in processed foods and high in whole, nutritional foods like vegetables and fruits,” said Percy Griffin, Ph.D., director of scientific engagement for the Alzheimer’s Association.
“So, it’s not surprising that this paper found that a diet high in ultra-processed foods impaired cognition in older adults,” he told Healthline.
Another study published in the journal Neurology last year also suggested there were benefits from a Mediterranean diet on brain health.
The researchers concluded that their findings corroborated the view that a Mediterranean diet could be a ”protective factor against memory decline and mediotemporal atrophy,” or shrinkage of the lobe of the brain associated with Alzheimer’s.
The Centers for Disease Control and Prevention estimatesTrusted Source that nearly 6 million people in the United States have Alzheimer’s and related dementias.
By 2060, the number of people diagnosed with Alzheimer’s is predicted to rise to an estimated 14 million.
Communities of color could be affected the most. Cases among Hispanics could increase seven times over the current estimates. Among African Americans, cases could increase four times the current estimates.
In San Francisco, a new community-based program is designed to focus on known modifiable risk factors to help prevent dementia.
Posit Science along with the YMCA is launching a model “Brain Health Program” funded by the National Institutes of Health.
The program, which is expected to be in operation in 6 months, will offer classes to at-risk adults. Part of the training will focus on the diet and nutrition principles the YMCA has been using in its Diabetes Prevention Program.
“Eating a brain-healthy diet is a big part of the Brain Health Program,” said Henry Mahncke, Ph.D., the chief executive officer of Posit Science.
“The future of brain health and dementia prevention is changing what we do in our everyday life so we build healthy, resilient brains that keep going as long as our bodies keep going,” he told Healthline. “Just about everything we eat gets sent by the bloodstream up to our brains, and so it’s not surprising to brain health experts that what we eat matters for our brain health, our cognitive performance, and our risk of dementia.”
The Australian researchers say their study is the first to investigate the association between ultra-processed foods and cognitive decline.
“As such, it sheds light for future studies that aim at providing stronger evidence unraveling potential mechanisms involved,” said Cardoso.
She explained the study had some limitations. It looked at a specific point in time whereas it may take years for impaired cognition to develop. They relied on participants to recall their dietary intake, which might not always be an accurate representation of their usual dietary intake.
“The next step for this research is to study if reducing the amount of ultra-processed foods in one’s diet could improve cognition,” said Griffin.
He noted that there will be more research on the impact of an unhealthy diet on dementia risk introduced at the upcoming Alzheimer’s Association International Conference that begins July 31.
The following article outlines what happens to our microbiome and gut flora change as we age.
How to make changes to help;
- Never eat cooked food without including some raw food, no exceptions! ONLY raw food has enzymes which help us digest food. Cooking destroys those enzymes.
- There is a reason that every culture has traditionally included fresh fruits or salads either before or after meals.
- Avoid sugar! Empty calories are a huge part of our health problems and keep us from meeting our nutrient needs.
- Avoid ALL processed foods; you should be able to look at the food and tell how it grew.
- Make 1/3 of your intake each day raw food.
We’re all crawling with bugs. Our bodies are home to plenty of distinct ecosystems that are home to microbes, fungi, and other organisms. They are crucial to our well-being. Shifts in the microbiome have been linked to a whole host of diseases. Look after your bugs and they’ll look after you, the theory goes.
These ecosystems appear to change as we age—and these changes can potentially put us at increased risk of age-related diseases. So how can we best look after them as we get old? And could an A-grade ecosystem help fend off diseases and help us lead longer, healthier lives?
It’s a question I’ve been pondering this week, partly because I know a few people who have been put on antibiotics for winter infections. These drugs—lifesaving though they can be—can cause mass destruction of gut microbes, wiping out the good along with the bad. How might people who take them best restore a healthy ecosystem afterwards?
I also came across a recent study in which scientists looked at thousands of samples of people’s gut microbe populations to see how they change with age. The standard approach to working out what microbes are living in a person’s gut is to look at feces. The idea is that when we have a bowel movement, we shed plenty of gut bacteria. Scientists can find out which species and strains of bacteria are present to get an estimate of what’s in your intestines.
In this study, a team based at University College Cork in Ireland analyzed data that had already been collected from 21,000 samples of human feces. These had come from people all over the world, including Europe, North and South America, Asia, and Africa. Nineteen nationalities were represented. The samples were all from adults between 18 and 100.
The authors of this study wanted to get a better handle on what makes for a “good” microbiome, especially as we get older. It has been difficult for microbiologists to work this out. We do know that some bacteria can produce compounds that are good for our guts. Some seem to aid digestion, for example, while others lower inflammation.
But when it comes to the ecosystem as a whole, things get more complicated. At the moment, the accepted wisdom is that variety seems to be a good thing—the more microbial diversity, the better. Some scientists believe that unique microbiomes also have benefits, and that a collection of microbes that differs from the norm can keep you healthy.
The team looked at how the microbiomes of younger people compared with those of older people, and how they appeared to change with age. The scientists also looked at how the microbial ecosystems varied with signs of unhealthy aging, such as cognitive decline, frailty, and inflammation.
They found that the microbiome does seem to change with age, and that, on the whole, the ecosystems in our guts do tend to become more unique—it looks as though we lose aspects of a general “core” microbiome and stray toward a more individual one.
But this isn’t necessarily a good thing. In fact, this uniqueness seems to be linked to unhealthy aging and the development of those age-related symptoms listed above, which we’d all rather stave off for as long as possible. And measuring diversity alone doesn’t tell us much about whether the bugs in our guts are helpful or not in this regard.
The findings back up what these researchers and others have seen before, challenging the notion that uniqueness is a good thing. Another team has come up with a good analogy, which is known as the Anna Karenina principle of the microbiome: “All happy microbiomes look alike; each unhappy microbiome is unhappy in its own way.”
Of course, the big question is: What can we do to maintain a happy microbiome? And will it actually help us stave off age-related diseases?
There’s plenty of evidence to suggest that, on the whole, a diet with plenty of fruit, vegetables, and fiber is good for the gut. A couple of years ago, researchers found that after 12 months on a Mediterranean diet—one rich in olive oil, nuts, legumes, and fish, as well as fruit and veg—older people saw changes in their microbiomes that might benefit their health. These changes have been linked to a lowered risk of developing frailty and cognitive decline.
But at the individual level, we can’t really be sure of the impact that changes to our diets will have. Probiotics are a good example; you can chug down millions of microbes, but that doesn’t mean that they’ll survive the journey to your gut. Even if they do get there, we don’t know if they’ll be able to form niches in the existing ecosystem, or if they might cause some kind of unwelcome disruption. Some microbial ecosystems might respond really well to fermented foods like sauerkraut and kimchi, while others might not.
I personally love kimchi and sauerkraut. If they do turn out to support my microbiome in a way that protects me against age-related diseases, then that’s just the icing on the less-microbiome-friendly cake.

At-home microbiome tests can tell you which bugs are in your poo, but not much more than that, as Emily Mullin found.
Industrial-scale fermentation is one of the technologies transforming the way we produce and prepare our food, according to these experts.
Can restricting your calorie intake help you live longer? It seems to work for monkeys, as Katherine Bourzac wrote in 2009.
Adam Piore bravely tried caloric restriction himself to find out if it might help people, too. Teaser: even if you live longer on the diet, you will be miserable doing so.
- Abdominal aortic calcification (AAC) causes calcium deposits in the abdominal aorta, a large artery that supplies blood from the heart to the abdominal organs and lower body.
- People with AAC have an increased risk of cardiovascular events such as heart attack and stroke.
- A new study shows that a diet high in flavonoid foods like black tea, apples, and cruciferous vegetables may prevent AAC and protect heart health, particularly among women.
- The findings indicate that older women who consumed more flavonoid foods were 36% less likely to have AAC compared to those who consumed fewer flavonoids.
- More research is needed to determine whether flavonoid-rich foods could prevent calcification in other arteries.
Could a cup of tea or an apple a day really keep the doctor away? Maybe not — but new research suggests that a diet high in flavonoids such as tea, fruits, and cruciferous vegetables may lower your risk of heart disease.
A recent study from researchers at Edith Cowan University (ECU) in Australia found that older women who consumed high levels of flavonoids from plant-based food sources were less likely to have extensive abdominal aortic calcification (AAC).
AAC happens when calcium deposits build up in your abdominal aorta, a large artery that supplies blood from your heart to your abdominal organs and lower body.
“This is just one of many, many studies that have shown a reduction in cardiovascular risk with eating more of a plant-based diet that’s rich in flavonoids,” Janice Friswold, RD, LD, a registered dietitian and diabetes educator at University Hospitals in Cleveland, OH, who was not involved in the new study, told Healthline.
“Some studies on flavonoids have also shown other benefits, such as reduction of cancer risk or cognitive decline, so there’s nothing but good stuff to say about these things.”
The ECU study was recently published in the journal Arteriosclerosis, Thrombosis, and Vascular BiologyTrusted Source, which is a journal of the American Heart Association.
Flavonoids are a type of plant compound found in fruits, vegetables, spices, tea, and other plant-based foods. They’re antioxidants that help protect cells from damage caused by oxidative stress.
Scientists have identified more than 6,000 types of flavonoids, which are classified into 12 main groups.
Six of these groups are found in common foods:
Common food sources
berries, grapes, and red cabbage
tea, wine, dark chocolate, apricots, apples, berries, and grapes
tea, berries, apples, onions, and cruciferous and leafy green vegetables, such as broccoli, kale, spinach, watercress, and parsley
celery, chili peppers, and herbs such as parsley, mint, oregano, and thyme
citrus fruits, such as lemon, orange, and grapefruit.
beans, lentils, peas, and soy-based foods, such as tofu and soymilk
“Eating a diet high in flavonoid-rich foods is really important,” Friswold said.
“I generally don’t recommend that people take [flavonoid] supplements because we know there’s over 6,000 different phytochemicals in the flavonoid group, and we’ve isolated a few of them, but who knows which is the magic combination.”
Instead, health and nutrition experts like Friswold encourage people to “eat the rainbow” by consuming a variety of fruits, vegetables, and other plant-based foods of different colors.
Edith Cowan researchers evaluated the eating habits of 881 older white women enrolled in the Perth Longitudinal Study of Ageing Women (PLSAW) to learn how flavonoid consumption could affect cardiovascular health.
These women were generally healthy and had no prior history of cardiovascular disease.
The researchers asked participants to complete food-frequency questionnaires to report how often they consumed certain foods and beverages during the past year.
The researchers also collected information about participants’ body mass index (BMI), smoking history, physical activity, and whether they had received a diagnosis or were taking medication for certain health conditions, such as diabetes, chronic kidney disease, high blood pressure (hypertension), or high cholesterol.
After controlling for these factors, the researchers found that older women with higher total flavonoid intake were 36% less likely to have extensive AAC than those with lower flavonoid intake.
Black tea was the main source of flavonoids in participants’ diets. Women who drank 2–6 cups of black tea per day were 16–42% less likely to have extensive AAC than those who drank none.
Among participants who didn’t drink black tea, flavonoid intake from other dietary sources was still linked to a lower risk of AAC.
Although the findings suggest that a flavonoid-rich diet has health benefits, the study does have limitations.
For instance, the researchers evaluated a relatively healthy and racially homogeneous group of women and only asked about them their eating habits over the past year rather than their lifetime.
It can be challenging for many people to accurately recall their eating habits, especially over longer periods.
“What we don’t know is whether participants have been following the same diet for years or if they used to be on a different diet and have recently become healthier,” Dr. Johanna Contreras, a cardiologist at Mount Sinai Hospital in New York, NY, told Healthline.
“My question is — if I change my diet to eat healthy starting tomorrow, will I get this benefit? Or is this a benefit that participants had because they’ve been eating like that for a long time?”
The study also focused solely on AAC rather than evaluating calcification in other arteries.
“Just because a person has aortic calcification doesn’t mean they have calcification in their main coronary arteries,” Friswold said.
“So nowadays, we’re doing a CT calcium score, which looks at the three main arteries to see if there’s calcification there.”
The new study from ECU is only one of many studies highlighting the potential benefits of eating a diet containing plenty of flavonoid-rich, plant-based foods.
For example, the authors of a 2013 study Trusted Source followed 93,600 healthy women from the Nurses Health Study II over 18 years and found that those with a high intake of anthocyanins had a lower risk of heart attack.
The authors specifically highlighted the apparent benefits of blueberries and strawberries, which are rich in anthocyanin.
And recently, in another new study published in Neurology, researchers linked antioxidant flavanol intake to slower memory decline.
Participants with the highest flavanol intake consumed an average of 15 milligrams daily, roughly equivalent to one cup of dark leafy greens.
The American Heart Association (AHA)Trusted Source encourages people to eat a wide variety of plant-based foods, including:
- 2.5 servings of vegetables per day
- 2 servings of fruit per day
- 6 servings of grains per day, with whole grains preferred over refined grains
Friswold said it can be helpful to place less emphasis on which type of protein you’re going to consume at each meal and focus instead on what you’re going to have for fruits and vegetables.
Getting enough sleep, avoiding smoking, and exercising regularly are also important for lowering the risk of cardiovascular disease and many other chronic conditions.
“I always tell patients that if you know you have risk factors for coronary artery disease or you have calcified plaques in the arteries, improve your diet and keep moving,” Contreras said.
“Good diet and exercise are very important.”
A diet rich in vegetables, whole grains, beans and lentils can cut the risk of bowel cancer in men by more than a fifth, research suggests.
A new study on 79,952 men in the US found that those who ate largest amounts of healthy plant-based foods had a 22% lower risk of bowel cancer compared to those who ate the least.
However, the researchers found no such link for women, of whom 93,475 were included in the study.
The team suggested that the link is clearer for men, who have an overall higher risk of bowel cancer.
They were also asked about portion size.
People could tick that they consumed each food item “never or hardly ever” right up to “two or more times a day”.
For drinks, the responses ranged from “never or hardly ever” to “four or more times a day”.
The food groups were classed as healthy plant foods (whole grains, fruits, vegetables, vegetable oils, nuts, legumes such as lentils and chickpeas, tea and coffee), less healthy plant foods (refined grains, fruit juices, potatoes, added sugars), and animal foods (animal fat, dairy, eggs, fish or seafood, meat).
The researchers then divided the daily consumption per 1,000 kcal into quintiles, from the biggest consumption to the least.
On average, men were aged 60 at the start of the study while women were aged 59.
We speculate that the antioxidants found in foods such as fruits, vegetables, and whole grains could contribute to lowering colorectal cancer risk by suppressing chronic inflammation, which can lead to cancer
Researcher Jihye Kim, from Kyung Hee University, South Korea, said: “Colorectal (bowel) cancer is the third most common cancer worldwide and the risk of developing colorectal cancer over a lifetime is one in 23 for men and one in 25 for women.
“We speculate that the antioxidants found in foods such as fruits, vegetables, and whole grains could contribute to lowering colorectal cancer risk by suppressing chronic inflammation, which can lead to cancer.
“As men tend to have a higher risk of colorectal cancer than women, we propose that this could help explain why eating greater amounts of healthy plant-based foods was associated with reduced colorectal cancer risk in men but not women.”
The authors found the link among men also varied by race and ethnicity.
The team said more research was needed on the differences between ethnicities.
During the study, 4,976 people (2.9%) developed bowel cancer and factors likely to influence the results, such as whether people were overweight, were taken into account.
Dr Helen Croker, head of research interpretation at World Cancer Research Fund, said: “We welcome this research which adds to our own evidence that eating vegetables, wholegrains and beans reduces the risk of developing bowel cancer.
“We also recommend that people limit the amount of red meat they eat and avoid processed meat altogether.
“Interestingly in this paper, plant-based diets were only associated with a lower risk of bowel cancer in men. It’s speculated that one reason for this may be because men in general had a lower intake of plant foods and a higher intake of animal foods than women – so there was perhaps a ceiling effect to the benefits that women may experience.”
Beth Vincent, health information manager at Cancer Research UK, said: “This American study adds to lots of existing evidence on the benefits of eating a balanced diet high in fruit, vegetables and fibre for both men and women.
“The research tried to compare ‘healthy plant foods’ and ‘unhealthy plant foods’ and found a link with bowel cancer in men. But because of the design of the study, the authors themselves acknowledge we can’t read too much into their results.
“The study relied on people remembering what they had eaten up to a year ago. It also made the assumptions that participants’ diets stayed the same over many years, and that all meat and animal products were unhealthy – which isn’t the case.
Low-Dose THC Has Positive Effect on Morbidity, Quality of Life and Mortality in Geriatric and Palliative PatientsPosted: October 22, 2022
The study was published by the peer-reviewed journal peer-reviewed journal MMW – Fortschritte der Medizin, as well as on the website for the U.S. National Library of Medicine.
“Cannabis-containing medicines have been successfully used in our practice for more than 20 years in pain and especially in geriatric and palliative patients”, notes the abstract of the study. “While it was initially a very indication-specific use (pain, loss of appetite, etc.) and also with higher THC doses, this changed over time to low THC doses and a therapy focus on suffering-perpetuating symptoms and especially on stress (Matrix of Symptoms).”

Below is the study’s full abstract.
Background: Cannabis-containing medicines have been successfully used in our practice for more than 20 years in pain and especially in geriatric and palliative patients. While it was initially a very indication-specific use (pain, loss of appetite, etc.) and also with higher THC doses, this changed over time to low THC doses and a therapy focus on suffering-perpetuating symptoms and especially on stress (Matrix of Symptoms).
Method: As part of the legally prescribed companion survey, we evaluated our data in parallel and discussed it publicly in a series of publications. Based on these published results, the article is intended to show an overview of our experiences.
Results: Low-dose THC has a positive effect on morbidity, side effects, quality of life and mortality in geriatric and palliative patients.
Conclusion: Early therapy is particularly appropriate in geriatric and palliative patients due to the clear benefit-risk ratio of low-dose THC.
In countries such as the UK, US, and Canada, ultra-processed foods now account for 50 percent or more of calories consumed. This is concerning, given that these foods have been linked to a number of different health conditions, including a greater risk of obesity and various chronic diseases such as cardiovascular disease and dementia.
Ultra-processed foods are concoctions of various industrial ingredients (such as emulsifiers, thickeners, and artificial flavors) amalgamated into food products by a series of manufacturing processes.
The intense industrial processes used to produce ultra-processed foods destroy the natural structure of the food ingredients and strip away many beneficial nutrients such as fiber, vitamins, minerals, and phytochemicals.
Many of us are well aware that ultra-processed foods are harmful to our health. But it’s been unclear if this is simply because these foods are of poor nutritional value. Now, two new studies have shown that poor nutrition may not be enough to explain their health risks. This suggests that other factors may be needed to fully explain their health risks.
The role of inflammation
The first study, which looked at over 20,000 healthy Italian adults, found that participants who consumed the highest number of ultra-processed foods had an increased risk of dying prematurely from any cause. The second study, which looked at over 50,000 US male health professionals, found high consumption of ultra-processed foods was associated with a greater risk of colon cancer.
What’s most interesting about these studies is that the health risks from eating a diet high in ultra-processed foods remained even after they had accounted for the poor nutritional quality of their diets. This suggests that other factors contribute to the harm caused by ultra-processed foods.
It also implies that getting the right nutrients elsewhere in the diet may not be enough to cancel out the risk of disease from consuming ultra-processed foods. Similarly, attempts by the food industry to improve the nutritional value of ultra-processed foods by adding a few more vitamins may be side-stepping a more fundamental problem with these foods.
Pre-cooking your vegetables before roasting them is the best way to make them caramelized, yet tender. You can either parboil your produce in water or stick to the single sheet pan prep and steam roast your veggies first, as recommended by Spoon University. By steaming the veggies before roasting them, your produce will retain its moisture instead of drying out.
In order to do this, preheat your oven to 375 degrees Fahrenheit. Then, chop your veggies into uniform-sized pieces and line a sheet pan with foil. Spread your veggies in a single layer on the pan and season with salt, pepper, and olive oil, and consider adding a few splashes of vinegar to give your roasted vegetables an extra kick. Cover the vegetables with a layer of foil and steam for half of the cooking time with the foil on. Remove the foil and uncover for the second half of the cooking time to allow the vegetables to roast and caramelize.
While this method will work for roasting nearly any vegetable, keep in mind, that cook time will vary depending on the type of produce you’re roasting. Root vegetables like beets, potatoes, and carrots may take up to 45 minutes, while thin veggies like asparagus and green beans only take 10 to 20 minutes, per The Kitchn.
I first had Eggplant Parmesan when I was 24 years old, I absolutely loved the flavor but felt like I could really improve on the texture. It seemed like it was just a gloopy mess, like a casserole. So I started playing with the recipe. It took a while to figure it out and here is the results!
I make my own Marinara Sauce as well as making the Vegan Parmesan Cheese. I use Violife Mozzerella Cheese. Although Follow Your Heart Brand makes Vegan Parmesan, it has almost no flavor. And Go Veggie Makes on that tastes good, it is a soy based product. I use very few soy products as they are not healthy. I will use Tempeh and Edamame occasionally as they are fermented and way easier to digest. I have a severe reaction to tofu and other processed soy products but do not react to edamame and tempeh.
Crispy Eggplant Parmesan Stacks
2 small eggplants (about 12 ounces each)
1 cup rice flour
3 large eggs , beaten
½ cup fine gluten-free breadcrumbs
1 teaspoon dried oregano
½ teaspoon freshly ground black pepper
½ cup vegan Parmesan cheese
½ pound vegan mozzarella , packaged or fresh, shredded
3 cups marinara, slightly thickened with tomato paste
Chopped fresh parsley to serve or pesto
Preheat the oven to 350°F. Lightly oil a rimmed baking sheet.
Leaving the peel on the eggplant, slice them into one-inch slices. Place the flour on a plate, and place the eggs in a shallow bowl. Mix the breadcrumbs with the oregano, 1 teaspoon kosher salt, and the pepper on a separate plate.
Coat both sides of each slice of eggplant in the plate with the flour. Dip each slice into the beaten eggs, then allow any excess egg to drip back into the bowl. Place the eggplant slices on the plate with the breadcrumbs, turn it to coat both sides. Place the coated eggplant on a sheet pan.
Bake eggplant in oven for about 12-15 minutes each side, just until golden brown, flipping half way through.
Place each browned slice of eggplant on the sheet pan, top with marinara, then mozzarella and parmesan. Place other slice on top of that, choosing one that is close in size or slightly smaller. Then put marinara on top, then mozzarella on top. Do not cover the entire top as you want some of the crispiness to stay crispy! Top with parmesan about 7 minutes before removing from oven. Remove from the oven
