High levels of phytic acid in soy reduce assimilation of calcium, magnesium, copper, iron and zinc.
Reduced does not clarify by how much or whether this is an actual issue. I take multi-minerals every day as habit anyhow so this is unlikely an issue for me.
Phytic acid in soy is not neutralized by ordinary preparation methods such as soaking, sprouting and long, slow cooking. High phytate diets have caused growth problems in children.
I am not a child.
Trypsin inhibitors in soy interfere with protein digestion and may cause pancreatic disorders. In test animals soy containing trypsin inhibitors caused stunted growth.
At around 6ft 5 this is not an issue.
Soy phytoestrogens disrupt endocrine function and have the potential to cause infertility and to promote breast cancer in adult women.
Male.
Soy phytoestrogens are potent antithyroid agents that cause hypothyroidism and may cause thyroid cancer.
This may or may not be true (I am not questioning or verifying truth). However 'may cause' is hardly enough to warrant panic.
In infants, consumption of soy formula has been linked to autoimmune thyroid disease.
Adult.
Vitamin B12 analogs in soy are not absorbed and actually increase the body's requirement for B12.
I take multi-vitamins each day.
Soy foods increase the body's requirement for vitamin D.
See above.
Fragile proteins are denatured during high temperature processing to make soy protein isolate and textured vegetable protein.
Not seeing the point.
Processing of soy protein results in the formation of toxic lysinoalanine and highly carcinogenic nitrosamines.
We live in a world of carcinogenic substances. In fact Professor Winston stated about cigarette smoking that if we all smoked lung cancer would be considered a hereditary disease. As such it is likely the case that you need to predisposed to this issue. I am not seeing this as a significant risk in general life and it is impossible to live without risk.
Free glutamic acid or MSG, a potent neurotoxin, is formed during soy food processing and additional amounts are added to many soy foods.
Not specific enough and no evaluation of risk or probability.
Soy foods contain high levels of aluminum which is toxic to the nervous system and the kidneys.
Not specific enough again.
Thanks for giving me the opportunity to look through this and these are simply my thoughts.
