Coffee, Green Tea, May Help Lower Stroke Risk, Research Shows

From Science Daily

Mar. 14, 2013 — Green tea and coffee may help lower your risk of having a stroke, especially when both are a regular part of your diet, according to research published in Stroke: Journal of the American Heart Association.

“This is the first large-scale study to examine the combined effects of both green tea and coffee on stroke risks,” said Yoshihiro Kokubo, M.D., Ph.D., F.A.H.A., F.A.C.C., F.E.S.C., lead author of the study at Japan’s National Cerebral and Cardiovascular Center. “You may make a small but positive lifestyle change to help lower the risk of stroke by adding daily green tea to your diet.”

Researchers asked 83,269 Japanese adults about their green tea and coffee drinking habits, following them for an average 13 years. They found that the more green tea or coffee people drink, the lower their stroke risks.

• People who drank at least one cup of coffee daily had about a 20 percent lower risk of stroke compared to those who rarely drank it.
• People who drank two to three cups of green tea daily had a 14 percent lower risk of stroke and those who had at least four cups had a 20 percent lower risk, compared to those who rarely drank it.
• People who drank at least one cup of coffee or two cups of green tea daily had a 32 percent lower risk of intracerebral hemorrhage, compared to those who rarely drank either beverage. (Intracerebral hemorrhage happens when a blood vessel bursts and bleeds inside the brain. About 13 percent of strokes are hemorrhagic.)

Participants in the study were 45 to 74 years old, almost evenly divided in gender, and were free from cancer and cardiovascular disease.

During the 13-years of follow-up, researchers reviewed participants’ hospital medical records and death certificates, collecting data about heart disease, strokes and causes of death. They adjusted their findings to account for age, sex and lifestyle factors like smoking, alcohol, weight, diet and exercise.

Green tea drinkers in the study were more likely to exercise compared to non-drinkers.

Previous limited research has shown green tea’s link to lower death risks from heart disease, but has only touched on its association with lower stroke risks. Other studies have shown inconsistent connections between coffee and stroke risks.

Initial study results showed that drinking more than two cups of coffee daily was linked to increasing coronary heart disease rates in age- and sex-adjusted analysis. But researchers didn’t find the association after factoring in the effects of cigarette smoking — underscoring smoking’s negative health impact on heart and stroke health.

A typical cup of coffee or tea in Japan was approximately six ounces. “However, our self-reported data may be reasonably accurate, because nationwide annual health screenings produced similar results, and our validation study showed relatively high validity.” Kokubo said. “The regular action of drinking tea, coffee, largely benefits cardiovascular health because it partly keeps blood clots from forming.”

Tea and coffee are the most popular drinks in the world after water, suggesting that these results may apply in America and other countries.

It’s unclear how green tea affects stroke risks. A compound group known as catechins may provide some protection. Catechins have an antioxidant anti-inflammatory effect, increasing plasma antioxidant capacity and anti-thrombogenic effects.

Some chemicals in coffee include chlorogenic acid, thus cutting stroke risks by lowering the chances of developing type 2 diabetes.

Further research could clarify how the interaction between coffee and green tea might help further lower stroke risks, Kokubo said.

More Consumers Giving Up Gluten Containing Foods

The following articles was published at CNBC today.  It documents that more and more people are giving up gluten containing foods.  While much of what they say in the article is true, they commented that many doctors challenge the fact that people lose weight when they give up gluten containing foods.  They can doubt it all they want…it IS true that you lose weight when giving up these foods.

You also have more energy, brain function improves, you sleep better, you have far less inflammation and bloating, the dry patches on the back of your arms and on your thighs as well as the dryness around the crease of your nose goes away…and you lose weight.

Humans do not tolerate grains well including the ones that have gluten.  They have enzymes that are toxic to us and are almost all empty carbs.  Your carbs should come from fruits and vegetables because they have a depth of nutrients not contained in grains. 

A Paleo diet, the one followed for hundreds of thousands of years by our ancestors was only abandoned in the 50’s and 60’s for the sake of convenience and profit margin for companies manufacturing processed foods.  Giving up grains, eating plenty of healthy saturated fats and grass fed meats along with organic cage free eggs and plenty of low glycemic vegetables IS the key to great health, high energy and happiness.

Benefits of Chocolate and Raw Cacao

I found a great web site that offers luscious raw chocolate confections but also great info on the health benefits of raw chocolate.

This study in the Journal of Cerebral Blood Flow and Metabolism indicates that the flavanols found in cacao may be helpful in preventing additional neural damage in the case of a stroke. This could indicate a protective function for the flavanols found in cacao, as cocoa was specifically used as part of the trial.

Additional details on the neuro-benefits of cocoa and more layman’s terms about the latest research from the Journal of Cerebral Blood Flow & Metabolism.

his study in the American Journal of Clinical Nutrition shows that heart health is increased by consumption of cacao. Blood pressure is reduced, and endothelial function improved in overweight adults.

“Chocolate contains more magnesium than any other food. Magnesium is the number one mineral deficiency in the west. It is the most powerful stress relieving mineral. It also relaxes the muscles and builds strong bones and teeth.” What more do you need?

Chocolate again scores well in a literature review for protective effects against heart disease. From the article published in Nutrition & Metabolism (Jan 3, 2006,) “The body of short-term randomized feeding trials suggests cocoa and chocolate may exert beneficial effects on cardiovascular risk via effects on lowering blood pressure, anti-inflammation, anti-platelet function, higher HDL, decreased LDL oxidation” and “Meanwhile, the large body of prospective studies of flavonoids suggests the flavonoid content of chocolate may reduce risk of cardiovascular mortality. Our updated meta-analysis indicates that intake of flavonoids may lower risk of CHD mortality”.

Another study, from the Archives of Internal Medicine February 2006.

Chocolate has been shown to have excellent antioxidant levels. ORAC (Oxygen Radical Absorbance Capacity) values of dark chocolate (13,120 per 100 grams) exceed those of prunes (5, 700); blueberries (2,400), strawberries (1,540) and spinach (1,260). Adding milk to chocolate does not help, in fact, it seems to block the activity of the phytochemicals responsible for the powerful antioxidant capacity of cacao. The August 28, 2003 issue of the journal Nature has a great article discussing the power of dark chocolate, of which, cacao is the key ingredient.

Researchers from the University of Cambridge in England have finally published solid evidence to demonstrate the consumption of chocolate is associated with improved heart and vascular health. Writing in the prestigious BMJ (British Medical Journal), Dr. Oscar Franco and his team determined several factors including diet, exercise, body weight control and lifestyle changes could help reduce the risk of heart disease, a condition expected to claim the lives of nearly 24 million people worldwide by the year 2030. The study authors found that the antioxidant and anti-inflammatory properties of cocoa from chocolate consumption could reduce heart disease risk by one-third and could also reduce the risk of sudden death from a heart attack and stroke incidence.

Cacao, ‘the food of the gods’ has received considerable attention lately as it has been found to contain one of the highest levels of antioxidants on the planet, exceeding red wine, green tea, and other exotic fruits and vegetables. Recently published in the peer-reviewed Journal of Agricultural Food Chemistry (December 3, 2003) is an article titled “Cocoa has more phenolic phytochemicals and a higher antioxidant capacity than teas and red wine”.

Cacao is showing benefits for reduction in blood pressure and greater insulin sensitivity in healthy persons. In an article titled “Short-term administration of dark chocolate is followed by a significant increase in insulin sensitivity and a decrease in blood pressure in healthy persons” published in the American Journal of Clinical Nutrition, March 2005, insulin sensitivity was improved almost 12% in 15 test subjects given dark chocolate and systolic blood pressure dropped almost 6% among the same group.

More testing shows that the antioxidant effects of cacao are helpful in arteriosclerosis. Testing with laboratory rabbits showed, “The antioxidative effect of Cacao Liquor Polyphenols was superior to those of the well-known antioxidative substances, vitamin C, vitamin E and probucol.” Arteriosclerosis, April 2005.

Cacao may help lower the oxidative stress of strenuous activities – thus helping athletes to recover. Recent research “conclude[s] that dietary flavanols, using cocoa drink as example, can lower the plasma level of F(2)-isoprostanes, indicators of in vivo lipid peroxidation.” Free Radical Biological Medicine, August 2004.

Free radical decreases have been noticed in subjects eating chocolate. In one trial there was a 16% drop in the amount of expelled free-radicals, indicating a higher antioxidant level in the subjects taking chocolate. Found in Nutr. Cancer, Vol 47, Iss 2, 2003.

The procyanidin found in Cacao have also been shown to inhibit cataract formation in diabetic lab rats. Experimental Biological Medicine, January, 2004.

All regular readers of NaturalNews know that researchers have discovered chocolate (especially the organic, not junked up with additives and sugar type) contains phytochemicals which appear to promote good health. But no one has had much of a clue about the specifics of some of those benefits on the cardiovascular system — until now. Scientists at the European Society of Cardiology Congress currently underway in Paris just announced that chocolate provides huge protection from heart disease as well as stroke.
