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

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 pressu

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.

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.

Analysis of insulin-producing cells has revealed that those with type 2 diabetes have epigenetic changes in approximately 800 genes, with altered

Data from 11 different cohort studies, involving more than 600,000 people from around the world, has found that:

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.

Data from AREDS2, involving 4,203 older adults with age-related macular degeneration, has found that daily dietary supplements of either omega-3 polyunsaturated fatty acids (also found in fish) or lutein and zeaxanthin (nutrients found in green leafy vegetables) were not associated with reduced

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.

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 f
