A review of just three studies found mixed results on chocolate and stroke: one of 44,489 people tied a weekly serving to 22 percent lower stroke risk, a second tied 50 grams a week to 46 percent lower stroke death, and a third found no link. The author says more research is needed.

Could Eating Chocolate Prevent Heart Attack Death?
Among 1,169 Swedish patients followed eight years after a first heart attack, those eating chocolate twice or more a week had 56% lower cardiac mortality than those who never ate it. The observational design cannot show cause, and the authors want confirmation.

Gluten and Casein-Free Diet May Help Those with Autism
A case report from Chang Gung University describes a boy with CHARGE syndrome who improved on a gluten- and casein-free diet: more eye contact and speech at 2.5 months, shared play at 5.5 months. The authors note no consensus supports dietary intervention.

Mediterranean Diet Cuts Risk of Brain Damage Linked to Cognitive Problems
Columbia's Nikolaos Scarmeas sorted 712 New Yorkers by how closely their diets matched the Mediterranean pattern, then scanned their brains about six years later. Those following it most closely were 36% less likely to have brain infarcts.

What You Need to Eat to Fight Heart Disease
The CDC's American Heart Month advice tells women to eat more fruit and vegetables and limit sugar, salt and fat; one observer wants specifics. A roundup of earlier studies follows, including vitamin K2 tied to 9 percent lower coronary heart disease risk per 10 micrograms a day.

Swine flu, vaccine and vitamins
A Harvard School of Public Health poll found 44 percent of American adults believe the 2009 swine flu pandemic is over, and 40 percent of parents have had their children vaccinated. CDC reported flat activity and nine more child deaths that week.

Why Grass Fed Dairy Products Are Better for You
Only 10 to 15 percent of US dairy farms are pasture-based, but Mercola argues grazing cuts fuel use, erosion and pollution, and that milk from pastured cows has repeatedly tested higher in vitamin E, beta-carotene, omega-3 and CLA. Pastured cows are also culled less often.

Many Celebrities, News Personalities Raise Heart Disease Awareness
Heart disease, not breast cancer, kills more American women than anything else, and the American Heart Association says rates have risen in women while falling in men. Women more often report dizziness, fatigue, nausea and radiating pain, and tend to wait rather than seek care.

Dietary Protein Affects Timing of Puberty
Tracking protein intake in 112 German children, researchers found those eating the most animal protein at ages 5 to 6 began their pubertal growth spurt 0.6 years earlier, with similar patterns for menarche and voice break. Higher vegetable protein intake tracked with later timing.

Having Sex Twice A Week Reduces Chance of Heart Attack by Half
A study of more than 1,000 men found those who had sex at least twice a week were up to 45 percent less likely to develop heart disease than men who did so once a month or less. Researchers suggest sex may mark overall health; women were not studied.

Roasting Does More than Enhance Flavor in Peanuts
USDA Agricultural Research Service scientists roasted peanuts at 362 degrees for up to 77 minutes and found darker roasts raised water- and oil-soluble antioxidant capacity in peanuts and peanut flour. Peanut skins, usually discarded as waste, scored high at every roast level.

Vitamin D newsletter: More letters on vitamin D and autism
A Vitamin D Council newsletter reprinting three reader letters sent in response to an earlier issue on autism, among them an aunt's account of her nephew's speech and mood improving after she gave him 2,000 IU of vitamin D a day.
Supplements
Fish oil may help autism
In a small Israeli trial, ten children with autism spectrum disorder took one gram of omega-3 fatty acids daily for 12 weeks, and eight of nine improved by 33 percent. The authors call the supplements safe and possibly helpful.
Supplements
Herbal remedies interfere with drugs for heart disease
Mayo Clinic cardiologists warn that St. John's wort, ginkgo biloba, garlic and even grapefruit juice can blunt or amplify heart medications, risking bleeding or serious arrhythmia. They say elderly patients taking several drugs at once face the greatest danger.

Childhood obesity linked to later onset of puberty in boys
Following 401 boys from ages 2 to 12, researchers found later onset of puberty in 14 percent of obese boys and 13.3 percent of overweight boys, against 7 percent of those at a normal body mass index.

Vitamin c help would healing
A 1982 report by Ringsdorf and Cheraskin described faster recovery in patients taking 500 to 3,000 mg of vitamin C daily after surgery, injuries and ulcers. Four grams a day also improved newly made collagen in a boy with Type VI Ehlers-Danlos syndrome.
