Patients responded to a question survey according to their dietary habits and been followed for vital status and the occurrence of cancer and other diseases. “We have tested the association between potential causal factors and the incidence of or mortality from cancer and other diseases…” Studies stating their typical dietary intake of low nutritional value in Japan mentioned are high consumption of soy/isoflavones,…”

Recent researchers found soy isoflavones similar to infant formula fed on mice plays a role for exposure to endocrine-disrupting chemicals (EDCs) in the obesity epidemic. “Obesogenic EDCs have the potential to inappropriately stimulate adipogenesis and fat storage, influence metabolism and energy balance and increase susceptibility to obesity.”

study discovered that exposure to soy-based infant formula resulted in negative effects on the long-term development of infants.
Study shows in rat model a negative effect(s) of thesex organs by their intake of soy (genistein). The inhibit of follicle, disrupts the production of sex steroid hormones, and alters the expression of steroidogenic enzymes. Like other phytoestrogens found in soy, this has the potential to mimic, enhance, or impair the estradiol pathway, thereby altering ovarian follicile growth.

Soy isoflavones have a tendency to mimic hormone estrogen. Because of the soybeans biological active molecules, this causes trouble especially with women on menopause.
Data shows that there is a link between long term soy consumption and Kawasaki disease (KD). Soy isoflavones play a role in this.

“Consumption by infants and small children is of particular concern because their hormone-sensitive organs, including the brain and reproductive system, are still undergoing sexual differentiation and maturation. Thus, their susceptibility to the endocrine-disrupting activities of soya phyto-oestrogens may be especially high.”

Early-life exposure to genistein, a naturally occurring component in soy formula, interferes with development of the reproductive system and changes in tissues that persist into adulthood, some may be related to menstrual pain.
Study found infant formula had negative effects on animals; including sexual development and reproductive function, neurobehavioral development, immune function, and thyroid function. This brought awareness associated with relevant abnormalities in children with congenital hypothyroidism.

Studies found the Soy isoflavones containing animal diets resulted behavioral issues. This influences estrogen-regulated systems, as well as dominating behavior and cognition.

A change in gender-related behavior in children and feminization associated with soy consumption. In animals, the excessive PhE intake leads to derangements of fertility, sexual development and behavior. PhE are called modulators or disruptors of the endocrine system.

Several studies have shown that bioactive ingredient in soy changes the expression in several cell receptors of different tissues and cancer cells. Therefore, consumption of soy isoflavones disrupt endocrine functions, such as thyroid function and reproductive performance, (because of their similar structure to estrogens). Furthermore, changing their gene expression, stimulates the sensitivity of cells or tissues to the affects of physiological functions, such as growth, development, osteogenesis, immune response, lipogenesis, reproductive process, and anticarcinogenesis.

A study has shown that high intake of soy and isoflavones increased the risk ofprostate cancer. “During 16.9 years follow-up, we registered 221 deaths from prostate cancer. Isoflavones and soy products intake was associated with an increased risk of prostate cancer death.”

Studies say the metabolites of the soy isoflavones play a risk of development and recurrence of breast cancer and its interactions with drugs used for treating breast cancer.

Collected data for over a decade from all around the world, showed an increase of women diagnosed with breast cancer. A case reported on the amount of isoflavone consumption and risk of breast cancer diagnosed in population, the result was 77.5% (7,209) were diagnosed.
