Soy (Soybeans) and Acne
Most people complain that soy causes allergic effects and acne. Around 0.5% of populations suffer from soy allergy and acne. Soy is a species of legume family and native to East Asia.
Beans of soy contain more than 40% protein and most of the proteins are heat-stable, that is, it can not be decomposed easily at ordinary cooking temperature. Studies show that existence of these proteins is the only factor that produces allergic effects and acne.
Soy does not cause acne on its first intake. When soy is taken for the first time, your immune system responds badly to soy and produces antibodies. Now the antibodies are become dormant and will be alive as soon as you take soy the second time and onward. Proteins are thought to be responsible for bad immune response and allergic effects.
Sebaceous glands or oil producing glands are extremely susceptible to bad immune response. Sebaceous glands are inflamed and produce excessive sebum. Excessive sebum clogs tiny hair follicles. Normal production of sebum and discharge through hair follicles is necessary for healthy skin. But, due to inflammation, hair follicles are narrowed and sebum is restricted within hair follicles.
The accumulation of sebum and bacterial infection rupture the walls of hair follicles. When hair follicles are ruptured, the lesion is called papule and the bump is called blackheads. If the sebum still stays inside, the bump is called whitehead.
Thus, soy kicks start a chain of allergic reaction that ends in acne breakouts.
Soy Not Used in Previous Centuries:
Pictographical data reveal that soy was designated unfit to eat as it contained many toxic chemicals and heat-stable proteins. It was not used even in East Asia, its native homeland. Toxins in soy inhibit the activities of trypsin and other protein digestive enzymes. Soybeans inhibit the absorption of essential nutrients such as calcium, magnesium, zinc etc as it contains high phytate contents.
Can fermented soy products cause acne?
Fermented soy products are somewhat safer than raw soy products as during fermentation, heat-stable proteins are destroyed that trigger your immune system. Consult your health care professional about the possible risks of fermented and non-fermented soy products. In some cases, taking fermented products is more risky than non-fermented products.
Soy produces allergic effects and directly targets the immune system. Immune system in return stimulates the sebaceous glands to produce excessive sebum and inflammation of hair follicles and lymph. If you noticed any allergic effect after taking soy, avoid it completely and consult health care professional.
