Are You a Soy-loving Health Food?

Soy is a popular choice for a health meal and has been the subject of a lot of research in the vitamin sciences. It may prove difficult to decode the results of such research. Here’s a brief overview of some of the soy studies. Soy is not the healthy food you have been led to believe it is.


So-call soy phytoestrogens are plant-derived estrogen-like compounds. They can be found in many plant species, including fruits, vegetables and legumes. The medical community has generally given phytoestrogens favorable reviews. Researchers suggested that phytoestrogens could also be beneficial in the prevention of arterial disease and may even protect against cancer in a 1997 Annals of Medicine article. However, it is not known if they can cause cancer.

Despite the positive claims made by phytoestrogens found in soy, little evidence has been provided to support their ability to lower cholesterol. Studies on animals and humans have shown that phytoestrogens don’t cause cardiovascular diseases. Although the research used soy protein isolated from plant sources, with or without phytoestrogens in it, they were not verified in humans.

Although it is not clear what the role of phytoestrogens is in breast cancer prevention, soy in the diet has been shown to reduce the risk for Asian women. A few studies suggest that phytoestrogens could also help to reduce the risk of developing cardiovascular disease in postmenopausal women. These beneficial effects have not been proven to be either low- or nonexistent. There is currently no evidence to support soy as a natural option for estrogen during menopause.

Phytic acid

The soy protein phytic acid (Ph), is a health-promoting agent. The fitness-promoting supplement phytic acid has been proven to be an effective one, stopping most cancers and osteoporosis. It also prevents despair and can even stop heart disease. Although the Phytic Acid found in Soy is good food, it can also cause adverse consequences.

Phytic acid can also bind to iron and other minerals. This makes it useful for concentrating on cancer cells that need iron, zinc, or calcium. It can also help to limit the harmful effects of  Nizagara 100 and Caverta 100, but it is not recommended.

Limiting soy consumption is one way to reduce the harmful effects of phytic acids in soy. A current study in rats determined that a weight loss program excessive in soy reduces the quantity of seasoned-inflammatory cytokines that cause the development of colon cancer. It is unclear how much phytic acids affects hormone levels.

Its primary function, however, is to maintain phosphorus in the vegetation. It also helps to grow phytates and other minerals. These compounds are too complex to be broken down by human enzymes, which prevents their absorption. Soy is not only immune to the harmful effects of phytic acids but also contains other nutrients.


Soy is high in protein but can also contain anti-nutrients which may cause gastric distress or deficiency of amino acids. Soybeans must be cooked for dinner to lose any anti-nutrients. Soy is rich in fiber and oligosaccharides which can cause flatulence and bloat.

Isoflavones are compounds found in soy that can mimic estrogen. Although estrogen has been linked to breast cancer, it is possible for isoflavones to mimic estrogen in the body. This mimicking effect can lead to hormone overload and even cancer in girls. Soy consumption reduces breast cancer risk for women with estrogen-negative breast cancers.

Soy can also interfere with the absorption of synthetic thyroid hormone which is used to treat hypothyroidism. You should wait at least 4 hours before taking synthetic thyroid hormones to avoid this problem. Numerous studies have shown that soy may help with symptoms of menopause. The authors of Menopause published an evaluation paper that referred to additional medical studies in order to examine the role of soy isoflavones for menopause fitness.


Goitrogens, chemicals found in soybeans, interfere with the function of the thyroid by blocking the conversion from iodine to thyroid hormones. This causes a decrease in thyroid hormone levels, which in turn can lead to an underactive thyroid. Hypothyroidism is a condition in which your thyroid hormone levels are low. Infection and autoimmune illness are the main causes of hypothyroidism in the United States. However, it also has a close relationship with digestive health issues. Antinutrients from soy can negatively affect your thyroid gland.

Even though we’ve known for more than 50 years about the negative effects of soy on the thyroid, scientists are still unsure how much soy should be consumed to prevent the development of goiter. Dr. Theodore Kay was the first to examine soybean intake and determined that a low amount of iodine can prevent goiter. However, high levels of iodine did not cause any thyroid gland pathological changes. Unfortunately, cooking cannot get rid of these goitrogens.

High levels of phytic acids are found in soy, which can cause problems with the body’s ability take in minerals. This is why many people are deficient in them. Protease inhibitors are also present in soy formula, which blocks enzymes that aid protein digestion. There have been reports of autoimmune thyroid disease in children who ate soy, and those who eat soy formula are more at risk.

Breast cancers

Recent research suggests that mammographic density and circulating estrogen levels are two intermediate biomarkers for breast cancers. Additionally, breast cancers can associate with changes in breast tissue and cell proliferation.

Although the evidence linking soy consumption to breast cancer is not conclusive, there are several studies that suggest soy may lower breast cancer risk.

Studies showed that women who ate more soy had fewer cases of the disorder than those who did not. It is not clear what the end result of this research, published in Cancer journal, will look like. These findings could prove to be a valuable food source for many women.
