Diet High In B-vitamins Lowers Heart Risks In Japanese Study

Eating more foods containing the B-vitamins folate and B-6 lowers the risk of death from stroke and heart disease for women and may reduce the risk of heart failure in men, according to Japanese research reported in Stroke: Journal of the American Heart Association.

“Japanese people need more dietary intake of folate and vitamin B-6, which may lead to the prevention of heart disease,” said Hiroyasu Iso, M.D., professor of public health at Osaka University.

The findings on the value of B vitamins were consistent with studies in Europe and North America, although the dietary consumption of vitamin B-6 is generally lower in Japan than in the United States.

Researchers analyzed data from 23,119 men and 35,611 women (ages 40-79) who completed food frequency questionnaires as part of the large Japan Collaborative Cohort (JACC) Study. During a median 14 years of follow-up, 986 died from stroke, 424 from heart disease and 2,087 from all diseases related to the cardiovascular system.

Investigators divided participants into five groups based on their intake of folate, vitamin B-6 and vitamin B-12. Comparing those with the diets lowest and highest for each nutrient, they found that higher consumption of folate and vitamin B-6 was associated with significantly fewer deaths from heart failure in men, and significantly fewer deaths from stroke, heart disease and total cardiovascular diseases in women. Vitamin B-12 intake was not associated with reduced mortality risk. Read more

Eating Peanuts Helps Keep Heart Healthy Without Weight Gain

WEST LAFAYETTE, Ind. (USA) – Adding peanuts to that apple a day that keeps the doctor away is a good way to stay heart-healthy and trim, says a Purdue University professor.

Research by Richard Mattes, professor of foods and nutrition, and his doctoral student, Corinna Alper, proves regular peanut consumption helps reduce the risk of cardiovascular disease without weight gain.

‘Peanuts are the most widely consumed nut in this country,’ Mattes said. ‘They are a rich source of monosaturated fatty acids, magnesium and folate, vitamin E, copper, arginine and fiber, all of which have cardiovascular disease risk-reducing properties.’

Mattes said the findings are consistent with several epidemiological and clinical studies.

‘Peanuts, which are actually legumes, are often viewed as unhealthy because they are high in fat,’ said Mattes. ‘This is the biggest obstacle in peanut consumption.

‘But peanuts are rich in the types of fats that actually reduce cardiovascular disease risk and have strong satiety properties – meaning a person feels full after eating peanuts – so they do not pose a threat of weight gain. People can feel comfortable including them in their diet to take advantage of peanuts’ reducing the risk of heart disease, without adding to body weight.’ Read more
