"Sprouted" garlic — old garlic bulbs with bright green shoots emerging from the cloves — have been found to have even more heart-healthy antioxidant activity than fresh garlic.

A study involving 44 middle-aged overweight men who consumed 70 grams of dark chocolate per day over two periods of four weeks, has found that dark chocolate helps restore flexibility to arteries while also preventing white blood cells from sticking to the walls of blood vessels. Both arterial stiffness and white blood cell adhesion are known factors that play a significant role in atherosclerosis.

A Finnish study has found that people who increased their intake of fatty fish to a minimum of 3–4 weekly meals had more large HDL cholesterol in their blood than people who were less frequent eaters of fish. Large HDL particles are believed to protect against cardiovascular diseases.

A large long-running study has found that eating a diet rich in animal proteins during middle age makes you four times more likely to die of cancer than a low-protein diet (a mortality risk factor comparable to smoking), 74% more likely to die of any cause within the 20-year study period, and five times more likely to die of diabetes. Even those eating a moderate amount of protein had much higher levels of mortality risk.

However, a high or moderate protein diet is helpful for those over 65, when levels of the growth hormone IGF-I drop off dramatically.

Middle-aged Japanese men living in Japan had lower incidence of coronary artery calcification, a predictor of heart disease, than middle-aged white men living in the United States, after accounting for risk factors such as smoking, cholesterol, alcohol consumption, diabetes and high blood pressure.

A new study from the Women's Health Initiative has found that calcium and vitamin D supplements after menopause can improve women's cholesterol profiles, with much of that effect tied to raising vitamin D levels. Taking the calcium and vitamin D supplements was especially helpful in raising vitamin D levels in women who were older, women who had a low intake, women who had levels first measured in the winter, and women who didn’t smoke and who drank less alcohol.

A study involving 362 children with reading problems has found that 16 weeks of daily 600 mg supplements of omega-3 DHA from algal sources improved their sleep. According to a sleep questionnaire filled out by parents, 40% of these children had significant sleep problems. Monitoring of 43 of the poor sleepers found that children taking daily supplements of omega-3 had nearly one hour (58 minutes) more sleep and seven fewer waking episodes per night compared with children taking a placebo.

A meta-analysis of 72 studies with over 600,000 participants from 18 nations has concluded that total saturated fatty acid, whether measured in the diet or in the bloodstream as a biomarker, was not associated with coronary disease risk. Nor was there any significant association between consumption of total monounsaturated fatty acids, long-chain omega-3 and omega-6 polyunsaturated fatty acids, and cardiovascular risk.

A review of 19 studies involving over 162,000 people has found that adherence to the Mediterranean diet was associated with a 21% reduced risk of diabetes, with a greater effect (27%) for those at high risk for cardiovascular disease. The association was found in both European and non-European groups.

The research was presented at the American College of Cardiology's 63rd Annual Scientific Session.

A study involving healthy men and women fed a baseline diet containing 550 mg choline/day (the adequate intake level set by the Institute of Medicine) for 10 days, then put on a low choline diet (50 mg choline/day) for up to 42 days, has found that the "right" amount of choline depends on many factors, including gender, age, and ethnicity.
