Love Health

Health old a “fire fish, meat phlegm,, vegetables and tofu for security and peace” that can really eat more soy products, “for security and peace,” it? Recently, the Shanghai Life Sciences, Nutrition Science Institute of scientists through the survey found that soybean protein on post-menopausal women’s health, but for men, more than soy protein intake on the health of the more complicated.

Lin led by nutrition researcher research group in 2005 in accordance with the collection “Chinese nutritional health status of aging population,” the crowd samples, an analysis of 2811 who meet the requirements of statistical data and found that soybeans, soy products and soy protein intake and metabolism integrated levy between risks, many have prompted significant correlation. The results were published in a recent field of international nutrition journal, “Journal of Nutrition” on.

Soy protein on the health of even some of the “men and women of light.” The first author doctoral thesis Pan told reporters that they first of all, the elimination of the age, geographical, smoking, alcohol consumption, physical activity, educational level, work status, disease status, and other dietary information confounding factors such as the impact of data and found that soy protein on post-menopausal women’s health the most useful, but the first time found that both men’s health benefits, while at the same time there are certain risks.

Scientists in accordance with the daily number of eating soy products, the 2811 people divided into four groups, at least a group of daily intake of about three grams of soy protein a maximum daily intake of a group of about 16 grams.Statistical analysis found that post-menopausal women to eat the most soy products group, diabetes, obesity and other metabolic syndrome risk, than a group of at least 34% less, lipid levels than at least one group. In the middle-aged men, soy intake may increase the metabolic syndrome and glucose risk trends, to eat the most soy products group, the risk of glucose than the lowest group for more than 60 percent higher, but suffer from the risk of abnormal blood pressure, than a group of at least 41 percent lower.

Although this is only statistical prompted, at present the relevant mechanism to be studied in depth.However, Pan believes that this prompted people to the role of soy protein also need to obtain further information.

Under the current scientific understanding of the information, Pan speculated that this situation may be related to soy isoflavones in soybeans relevant. Natural plant hormones such as “both sides” and can change with the dose, the human sex hormone level of the body, as well as different types of target organ played, respectively, and anti-estrogen effects of estrogen: If postmenopausal women with estrogen level significantly reduced, soy isoflavones play a type of estrogen effect on the health of some help; Instead of young women and men of different hormone levels in the body, soy isoflavones on the body hormone balance will be different.

He said that the U.S. has been a study to male monkeys fed isoflavone-rich soy protein and found that more than intake group more prone to insulin resistance (a precursor to diabetes). And before the crowd in response to the Asian study, also found that soy protein for premenopausal and postmenopausal women’s urine sugar levels and blood pressure of men and women that there are differences.

However, Pan stressed that the current study is based on the general population cross-sectional study, it is difficult to avoid some unknown confounding factors of interference, the future needs of different gender, different age groups of the population by tracking research and clinical intervention to confirm . Therefore there is no sufficient evidence that eating soy products should be.
