Soy is one of the foods with the highest concentration of isoflavones, phytoestrogens that naturally regulate the hormonal production of the body. This balancing effect is particularly useful for women who wish both to ensure a proper and regular hormonal balance and also to naturally enhance their breast, since soy isoflavones naturally stimulate the production of good estrogens which bind to the receptor cells in the mammary glands thus contributing to the healthy development of the bust. Soy isoflavones also block the reception of dangerous and carcinogenic estrogens of chemical origins, thus also hleping in protecting the breast (and the body in general) from the risks of cancer. There are numerous clinical studies about the cancer-preventing effects of soy isoflavones.
Soy is thus the optimal ingredient for Wonderup besides being an amazing food and food supplement which should be included in our daily diet.
Other characteristics and
Soy is a greatly valued food which is gaining growing appreciation as a nutritional ingredient not only in the diet of vegetarians but also of everyone who is health conscious. Many soy supplements are also continually being developed and gaining popularity.
Soybeans have a similar taste to beans and can be eaten in the same way as legumes. But soy is mostly popular for its derivatives which have a more appealing taste, such as soy oil, soy meal, soy sauce (an excellent dressing and subsitute for salt, widely used in Chinese cooking), soy milk, soy ice cream, tofu (a very popular cheese-like food), hamburger and sausages made with soy which are very popular among vegetarians as substitues for meat. Soy indeed is composed of 44% protein - the highest concentration in legumes, much more than chick peas, lentils or broad beans.
Soy also gives an excellent substance for overall health: lecitin, a natural emulsifier which keeps colesterol in the blood in suspension, preventing it from sticking to the artheries. It is thus excellent for lowering high cholesterol levels. Cholesterol deposits are in fact the main source of cardiovascular illnesses. Soy lecitin also enters the structure of cells bringing two of the main antioxidants: vitamin A and phosphorus.
Phytoestrogens contained in soy can effectively protect men from prosthate cancer and women from illnesses associated with the production of estrogens such as breast cancer, endometriosis, fibrocystic dieases, uterine fibromas and the problems of menopause. The low percentage of these illnesses in Asian women could be due to their high consumption of soy foods, especially tofu. In fact, Asian women don't even have a term in their languages for "hot flashes" - they simply don't know what they are!
The presence of isoflavones thus makes soy an excellent help for the problems of menopause. Soy isoflavones act like all phytoestrogens by balancing both conditions of estrogen excess (like PMS syndrome) and conditions of estrogen deficiency (like menopause), bringing hormones to proper levels. Thus they alleviate menopausal symptoms like hot flashes, night sweats and mood swings. In menopause therefore they provide an excellent and safe alternative to synthetical hormones.
Curently, research is indeed under way on the two phytoestrogens
of soy that are most known: genistein and daidzein, for their ability to
regulate hormonal imbalances.

Chinese having a regular consumption of soybeans and/or tofu have only one-half as much cancer of the stomach, colon, breast and lung compared with those Chinese who rarely consume soy or soy products. Soybeans contain fairly high levels of several compounds with demonstrated anti-cancer activity, including a high content of isoflavonoids, such as genistein. These isoflavonoids have been shown to inhibit the growth of both human breast and prostate cancer cells. In addition, regular use of soy protein (soybeans, tofu, soy nuts, soy beverage) can lower blood cholesterol and triglyceride levels by 10 to 15 percent, especially in persons with elevated lipid levels.

Phytoestrogens of Soybeans: An
Alternative Approach to Traditional HRT ?
Traditional postmenopausal hormone replacement therapy
(HRT) preserves bone density, reduces the risk for coronary heart disease and may sustain
cognitive function with aging. Despite these health benefits compliance is poor (about 10
percent of women older than 55 years). Poor compliance relates primarily to fear of breast
cancer and the need for co-administration of progestin to those with uteri. We have
focused on the phytoestrogens (genistein and daidzein) from soybeans as potential
alternatives to traditional HRT - particularly because they may be breast cancer
protective and are antiestrogens for the endometrium thus obviating the need for a

Soy Protein Isoflavone Effects on
Isoflavones, so abundant in soy, have been shown to have biochemical and biological effects in a variety of in vitro and animal models. These effects are not only based on the estrogenic properties of isoflavones, but also their role as protein tyrosine kinase inhibitors, regulators of gene transcription, modulators of membrane transporters, and as antioxidants. Predicting the outcome of the effects of isoflavone-rich diets, such as those based on soy, on chronic diseases (cancer and heart disease) should not be based on one of these mechanisms alone. For instance, the prevention of osteoporosis by isoflavones (an estrogenic effect) is in contrast with epidemiological and laboratory data which suggest soy and isoflavones prevent cancer. However, the recent discovery of new estrogen receptor (ERP) which selectively binds the isoflavone genistein is providing new rationales to explain the estrogen paradox. ERP shows a different tissue distribution from the classical estrogen receptor, being abundant in bone, the brain, cardiovascular system, genitourinary system, lungs and prostate, but not in the breast. This allows genistein to have beneficial effects at these targets without increasing the risk of breast cancer. Thus the isoflavones may be naturally occurring forms of an important new class of drugs called selective estrogen receptor modulators (SERMs), being developed for the treatment of the postmenopausat disease in women.

BIOCHEMISTS in the US have worked out how a key ingredient
in soya beans thwarts cancer. Thev have shown that genistein, a plant oestrogen,
plays a pivotal role in suppressing the growth of cancerous cells. Asian diets high
in soya have been linked with low incidence of cancers, particularly breast, colon and
prostate cancers. This link has been reinforced by evidence that when Asians migrate to
the US and abandon the high-soya diet, their risk of developing these cancers increases.
Amy Lee of the University of Southern California in Los Angeles has discovered that
genistein is a key factor in this. It works by weakening cancer cells' response to the
stresses that usually impel them to grow faster. "When a cancer cell is growing at
full blast, the cells soon run out of oxygen and glucose that are normally supplied in
blood," savs Lee. To compensate, they send out a chemical SOS which triggers
formation of new vessels to nourish the tumour, a process called angiogenesis.
