The products drifted of the soy, such ace tofu, the natto and the miso, would contribute to warn the cardiovascular illnesses at the women. It is what the results of a vast track indicate during ten years by a cohort of more than 40 000 Japanese and Japanese of 40 years to 60 years.
The researchers valued the daily consumption of proteins of soy of each of the topics, then they counted the cases of coronary thrombosis and intervening cerebral vascular accidents within the cohort. According to the results, the women who consumed the more of soy ran 60% less risks to endure cardiovascular unrests compared to those that consumed the less of them.
Among postmenopausal women, the reduction of the risk reached 75%. The results don’t indicate such a reduction of the impact of the cardiovascular illnesses relatively at the men to their consumption of soy products.
It is believed that the cardioprotective effect observed Japanese among women is due to the isoflavones that contains soybeans, mainly genistein, daidzein. Thesis substances, also called phytoestrogens, haggard would has similar effect to the female hormone whose activity decreases significantly at the time of menopause.
This reduction of the hormonal activity would predispose the women to the cardiovascular unrests at the time of the menopause, that occurs toward the a.e of 40 years to 60 years. A contribution in phytoestrogènes could counter this elevation of the cardiovascular risk at the women of this age group, believe the researchers.
In addition to the isoflavones, soy also contains polyunsaturated fatty acids, including linoleic acid, vitamin E and omega 3. These nutriments could contribute to lower the blood rates of cholesterol, to decrease the arterial tension and to improve tolerance to the insulin.
He/it agrees however to note that the quantities of soy proteins consumed in Japan pass those of the average of the Western extensively. In the present survey, the topics that had a so-called consumption curbed of soy absorbed some about 20 times more that a middle Western. The Japanese of which the risk of cardiac unrests was the weakest consumed consumed the equivalent daily of about 45 g of natto or 100 g of tofu, indicate the results of the survey
