Fitness Myths

SOYA is a lifesaver when it comes to getting protein from natural sources for vegetarians and vegans. In fact, it is one of the most easily available and cheapest forms of protein available. 100 gm soya chunks provide 52 gm of protein which is one of the highest per 100gm, and which is by the way even higher than meat or any other plant based food sources. SOY provides complete protein profile i.e. it consists essential amino acids required in nutrition. SOY BV is higher than that of lentils, rice and wheat; It not only has high satiety index, but is also a good source of fiber and vitamins. Hence it is one of the best protein sources from plants and thus a desirable choice for vegans and vegetarians. (BV is the measure of protein absorbed by human body from food sources) THE CONCERN Despite its high nutritional value, SOYA products have been blamed for promoting FEMINIZING EFFECTS in men, lowering testosterone levels, impacting thyroid functions adversely especially for people already suffering form Hypothyroidism and the most scary one being it leads to breast cancer in women. WHY THE CONCERN? SOYA has ISOFLAVONES, which act has PHYOESTROGENS that function like ESTROGEN in mammals. Since estrogen is a primary female hormone, SOYA has been linked with PROMOTING feminizing effects & reducing TESTOSTERONE levels in men. WHAT SCIENCE SAYS There have been several clinical studies done on analyzing the impact of Isoflavones on men where they were consuming 150 gm ISOFLAVONES and NO IMPACT ON MEN WAS OBSERVED. In other words, 100 gm Soya has 10 gm ISOFLAVONES. So, to get 150 gm ISOFLAVONES daily you would need to consume more than 1.5 kg SOYA CHUNKS a day which is humanly impossible to even consider any possible impact. Several similar studies have been done to analyze the impact on breast cancer development and the impact on hypothyroidism but none of them pointed towards any such scientific evidence. Unfortunately, in the digital age, studies get ignored and rumors spread fast. Science has cleared the way for SOY to be consumed by men and women with no negative impact on health. TAKE AWAY: • SOYA IS SAFE for men in normal consumable quantities. • HYPOTHYROIDISM is NOT adversely impacted by SOYA in normal consumable quantities. • It is a High Quality, High Protein Content food ingredient • IT DOES NOT cause any rise in estrogen levels or impact thyroid function adversely. • IT DOES NOT increase the risk of breast cancer Disclaimer: The studies are from credible sources. For medical conditions, please listen to your doctors advice.

Sir , where do you get this information that soya chunks has 10mg isoflavone for every 100gm of soya chunks ? And does defatted soy flour also have same amount of isoflavones per 100gm ?
