Low dietary fiber intake linked to increased cardiovascular risk

Data from the very large U.S. National Health and Nutrition Examination Survey (NHANES), involving 23,168 people, has found a significant association between low dietary fiber intake and risk of metabolic syndrome, cardiovascular inflammation, and obesity.

Dietary fiber intake was also consistently below recommended intake levels: 38g per day for men aged 19-50 years, 30g per day for men 50 and over, 25g for women aged 19-50 years, and 21g per day for women over 50. Mean dietary fiber intake was only 16.2g per day across all groups.

Whole diet approach better for reducing cardiovascular risk

A review of research from 1957 to the present has concluded that a whole diet approach, and specifically Mediterranean-style diets, has more evidence for reducing cardiovascular risk than strategies that focus exclusively on reduced dietary fat.

Why dark chocolate is good for your heart

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.

Increased intake of fish can boost good cholesterol levels

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.

More fish needed for healthy heart?

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.

Link between fatty acids and heart disease complex

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.

Supplements don’t reduce risk of cardiovascular disease in elderly

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 risk for cardiovascular disease (CVD).

Calcium supplements not associated with increased cardiovascular risk in women

Contradicting some earlier studies, new research using data from the very large and long-running Nurses' Health Study has found that calcium supplement intake was not associated with a higher risk of cardiovascular disease in women.

Sugar implicated in cardiovascular disease risk independent of weight gain

A review and meta-analysis of all international studies that compared the effects of higher versus lower added sugar consumption on blood pressure and lipids (blood fats or cholesterol) has uncovered evidence that sugar has a direct effect on risk factors for heart disease, and is likely to impact on blood pressure, independent of weight gain.
