Mice given a single dose of epicatechin, a compound in dark chocolate, suffered significantly less brain damage after an induced stroke. The protection held when the compound came 3.5 hours afterward but disappeared at six hours.

Cholesterol, eggs raises heart risk in older people
Among 1,941 older adults followed nine years, dietary fat was not linked to cardiovascular events, but those in the top third for cholesterol intake had 47 percent higher risk, and people eating more than three eggs a week were 68 percent more likely to have a heart attack, coronary death or stroke.

Drinking alcohol boosts risk of death from cancer
Following 6,291 Korean residents aged 55 and older for two decades, researchers found heavy drinkers were 5.62 times more likely to die of esophageal cancer and 4.59 times more likely to die of colon cancer than abstainers. Among women the difference was not statistically significant.

Fruit and vegetables prevent benign breast tumor
Comparing 327 Shanghai women with fibroadenomas to 1,070 controls, researchers linked higher fruit and vegetable intake to lower risk of these benign breast tumors. Live births, natural menopause, oral contraceptive use and moderate exercise also tracked with reduced risk.

No reason to avoid having sex after a heart attack
In a survey presented to an American Heart Association meeting, only half of men and a third of women said doctors raised sexual activity before discharge after a heart attack, and many then avoided it. Harvard's Murray Mittleman says the risk is negligible and regular exercise nearly erases it.

Green Tea Could Reduce Glaucoma Risk
Rats given green tea absorbed its catechins into eye tissues including the lens and retina, from 30 minutes to 12 hours after drinking. The retina took up the most gallocatechin. Mercola reads the finding as a possible route to protecting eyes against glaucoma.
Food
Processed meat linked to elevated risk of heart disease, diabetes
A Harvard meta-analysis in Circulation linked each 50 grams of processed meat eaten daily, about one hot dog, with 42 percent higher heart disease risk and 19 percent higher diabetes risk. Unprocessed meats showed no such link, and researchers suspect the salt and nitrate preservatives.

Diet linked to Alzheimer's disease risk
People aged 65 and over who ate more nuts, fish, tomatoes, poultry, cruciferous vegetables, fruit and leafy greens were up to 38 percent less likely to develop Alzheimer's over 3.9 years, in a study of 2,148 people. Those with the disease ate more high-fat dairy, red meat, organ meat and butter.

Forget about statins! Eat lots of nuts instead
Joan Sabate and colleagues pooled 25 studies from seven countries covering 583 people and found that eating about 67 grams of nuts a day cut total cholesterol roughly 5% and LDL 7%. Benefits looked larger in thinner people and those with high LDL.

Coffee, soft drinks not linked to colon cancer risk
A meta-analysis of 13 studies covering 731,441 people found no higher colon cancer risk among those drinking more than six cups of coffee or more than 18 oz of sugar-sweetened soda daily. Heavy non-herbal tea drinking showed a moderate link, but few participants drank that much.

Demonized Since the 1950s – Yet Still One of Healthiest Foods Available
Mark McAfee, founder of raw milk producer Organic Pastures, distinguishes milk produced to be drunk raw from raw milk headed for pasteurization, and argues the two are not the same. Six states permitted retail raw milk sales at the time, each setting its own standards.

Green Tea Extract May Be More Effective than You Thought
A randomized, placebo-controlled crossover trial found EGCG, a compound in green tea, increased fat oxidation by 33 percent in obese men within two hours of a meal. The authors call it a pilot study and the first evidence that a single green tea catechin can do this.

Could eating chocolate raise depression risk?
A survey of 931 men and women not on antidepressants found those screening as depressed ate 8.4 servings of chocolate a month against 5.4 for the rest, rising to about 12 with major depression. The researchers say the data show no causal direction either way.

Study: Energy Drinks May Raise Heart Attack Risk
Fifty healthy volunteers drank one 250 ml sugar-free energy drink. An hour later platelet aggregation had risen while endothelial function fell and arterial pressure rose. The authors report only these acute changes in healthy young adults.

Meat ups bladder cancer risk
University of Texas researchers examined data from 1,700 people and found those who regularly ate well-done meat were more than twice as likely to develop bladder cancer as people who preferred rare meat. Certain genes raised risk almost fivefold, the lead author said.

How does sugar raise heart disease risk?
A JAMA study led by Miriam Vos found high added-sugar intake tracked with worse blood lipids, including an unfavorable triglyceride-to-HDL ratio. It was not a trial, so it cannot show sugar caused the risk. Hu and Malik point to glycemic load and fructose as possible mechanisms.

Eating too much sugar raises heart disease risk
Miriam Vos and colleagues analysed U.S. nutrition data and blood lipids from more than 6,000 adults and found those eating more added sugar had higher triglycerides and higher triglyceride-to-HDL ratios. Participants averaged 46 teaspoons of added sugar a day.

Fiber and nuts cut BBD risk
Among 29,480 Nurses' Health Study II women who recalled their high school diets, those in the top fifth for adolescent fibre intake had 25 percent lower risk of proliferative benign breast disease, and those eating two or more servings of nuts a week were 36 percent less likely to be diagnosed.
