FITNESS TIP OF THE WEEK:  JUST SAY NO TO SOY!

Think you’re doing yourself a healthy favor by switching to soy products?  Think again!  I felt the same way until I was educated about “Soy Dangers”.  Fermented soy such as tempeh, natto and tamari are fine to use in small amounts; the fermentation neuralizes the toxins.  It’s the unfermented soy we need to be wary of. It is processed in such a way that denatures proteins and increases levels of carcinogens.

To summarize:
  a.. High levels of phytic acid in soy reduce the assimilation of calcium, magnesium, cipper, iron and zinc.  High phytate diets have caused growth problems in children
  b.. Trypsin inhibitors in soy interfere with protein digestion and may cause pancreatic disorders
  c.. Soy phytoestrogens disrupt endocrine function and have the potential to cause infertility and to promote breast cancer in adult women.
  d.. Soy phytoestrogens are ptent antithyroid agents that cause hypothyroidism and may cause thyroid cancer
  e.. Vitamin B12 analogs in soy are not absorbed and actually increase the body’s requirement for B12
  f.. Soy foods increase the body’s requirement for vitamin D.  Toxix synthetic vitamin D2 is added to soy milk
  g.. Fragile proteins are over-denatured during high temperature processing to make soy protein isolate and textured vegetable protein
  h.. Processing of soy protein results in the formation of toxic lysinoalanine and hightly carcinogenic nitrosamines
  i.. Free glutamic acid or MSG, a potent neurotoxin, is formed during soy food processing and additional amounts are added to many soy foods to mask soy’s unpleasant taste
  j.. Soy foods contain high levels of aluminum, which is toxic to the nervous system and the kidneys
  k.. Babies fed soy-based formula have 13,000 to 22,000 times more estrogen compounds in their blood than babies fed milk-based formula.  Infants exclusively fed soy formula receive the estrogenic equivlalent of at least five birth control pills a day.
