Using Soy Products For Hot Flashes

By Annette Caruso


Unpleasant symptoms accompany menopause for millions of women. Sudden rises in body temperature and 'night sweats' are among the most common complaints. Prescription drugs and artificial hormones can help mitigate the severity of these symptoms, but they have side effects that cause concern. Many women prefer to use soy shakes for hot flashes and other signs of hormonal imbalance.

These and other symptoms are caused by a decline in estrogen and other hormones. It is natural for estrogen to decline with age, but the body still needs estrogen to function properly. Progesterone, another hormone, can be used, but this hormone also may be deficient. The pituitary gland reacts by secreting LH, or luteinizing hormone, in an effort to balance the system. However, this hormone does not act like estrogen in the body, and too much of it causes blood vessels in the face, neck, and torso to swell. It also activates sweat glands. This results in excessive perspiration and hot flashes.

Soybeans contain substances called isoflavones which are phytoestrogens, or plant estrogens. These are considered bio-identical to estrogen and progesterone, which are naturally produced by the human body. The body can use the isoflavones as it does estrogen, which mitigates or eliminates temperature fluctuations, mood swings, and excessive perspiration. Soy is processed to yield concentrated forms of the plant hormones, which are sold as powders or capsules.

Genistein is one of the isoflavones that have been clinically proven to bind to receptors in human cells that absorb estrogen. Genistein should come from organic soy and be made by a reputable manufacturer. Many women take this supplement in capsule form as an easy way to get balance their systems.

Mitigating the unpleasant effects of menopause is important, but there are even more compelling reasons to provide bio-identical hormones for the aging body. Estrogen-like substances in plastics can be absorbed by the body if there is a lack of the true hormone. These components of plastic have been found to be carcinogens. They are being studied as possible contributors to the growing rates of breast and ovarian cancers.

You don't have to take supplements if you consume soybeans as food. To get health benefits, it's important to use whole fermented soy. Tofu, tempeh, and miso are tasty ways to add fermented products to your diet. Soy milk, in contrast, is neither fermented or whole and is not a good source of isoflavones. Neither is the concentrated - or 'isolated' - protein found in energy bars. Look for fermented forms of the bean in the ingredients list of products you buy.

Westerners are not familiar with the fermented foods of the Far East. Supplements have become more popular than the ethnic foods. However, it might be wise to acquire a taste for miso soup and other soy-based delicacies. Foods often contain the whole soybean, which some feel is more healthy than using supplements that isolate and offer only part of the bean.

It's important to get supplements and foods from reputable sources. Soy is commonly genetically modified and grown with huge applications of herbicides, so look for an organic label. Organic standards don't allow chemical fertilizers, herbicides, or pesticides to be used by farmers.

Supplements and ethnic foods should be part of a total health plan during menopause. Exercise, fresh air, lots of pure water, and a good stress reduction regimen are all important for well-being. Avoiding spicy foods, limiting caffeine, and eating fresh vegetables are other ways to a trouble-free transition from the childbearing years to the golden ones.
