To date the only area attracting any widespread consensus of caution is the feeding of infant formula based on soy to infants. This is very much based on hypothesis though as there is not yet epidemiological data which confirms this caution. Another case is where women are having difficulty conceiving. Some nutritionists suggest that in this case women may wish to experiment with restricting their intake of soy products. Return to top.
Some individuals have an allergy to soy protein.
Soya allergy is a form of food sensitivity and involves a strong reaction from the body's immune system. Normally the immune system protects the body from undesirable substances such as harmful bacteria and viruses, but in the case of allergy it reacts to certain substances found within soya. The substance which causes the reaction is known as an allergen. Normally this is either a protein or a substance closely associated to a protein. In those who show an allergic reaction to soy, the protein that is the cause of or that carries the allergen, produces a reaction from the body's defence mechanism.
