Autoimmune Thyroid Disease

An Unfortunate and Lengthy Adventure in Misdiagnosis

Dear "Healthy" magazine

I don’t believe for one minute that “Healthy” Magazine will publish this and get the message out… “Healthy” is produced directly for Holland and Barrett and used to promote the products they sell, including their wide range of soya products. I’m a regular customer of Holland and Barrett and I know that their magazine reaches a great number of health nuts. I’m merely trying to stir up a bit of trouble in the editor’s office: if I can make one journalist think twice about this kind of sneaky promotional advertising, well, it will have been worth it.

Dear Healthy Magazine,

I am deeply concerned by your promotion of soya in the March/April 2005 issue. I have never written to a magazine before, but I am so concerned by the bias expressed I feel moved to do something. The soy industry is a very powerful lobby able to buy a lot of space and publish a lot of selective “scientific” studies and I feel that the truth is not being told because of this. Years ago as a vegetarian teenager, my own health suffered severely due to consumption of soy products and I feel it is in your reader’s best interests to learn about the darker side of soya:

  • Phytic acid in soy reduces assimilation of essential minerals and is not neutralised by ordinary preparation.
  • Trypsin inhibitors in soy interfere with protein digestion and may cause pancreatic disorders.
  • The high-temperature processing soy undergoes over-denatures the proteins, it forms MSG (neurotoxin), lysinoalanine (toxic), nitrosamines (carcinogens) and results in high levels of aluminium which is toxic to the nervous system and the kidneys.
  • Vitamin B12 analogs in soy are not absorbed and actually increase the body’s requirement for B12. Soy foods also increase the body’s requirement for vitamin D. Soy phytoestrogens (isoflavones) disrupt endocrine function and have the potential to cause infertility and to promote breast cancer in women.
  • Soy phytoestrogens are potent antithyroid agents that cause hypothyroidism and may cause thyroid cancer.
  • Babies fed soy-based formula receive the estrogenic equivalent of at least five birth control pills per day.
  • Soy consumption is associated with delayed puberty in boys and premature puberty in girls.
  • Even moderate intake of phytoestrogens during pregnancy can have adverse affects on the developing foetus and timing of puberty later in life.
  • Tofu is consumed by Buddhist monks to reduce libido. Researchers theorise that the high phytoestrogen content in soy is a self-defence mechanism that prevents the proliferation of animals who would otherwise eat the plant, by effectively putting them on “birth control pills.”
  • In Japan, tofu consumption in mid-life is associated with Alzheimer’s disease in later life.
  • Average consumption of soy food in China is only 10 grams (2 teaspoons) per day, soy is almost always consumed in a fermented form such as tempeh, natto or tamari which neutralises many of the toxins that actually remain preserved in the modern tofu and soy mince dishes consumed in the West. As a crop, soy is used to fix nitrogen into the soil, it has never been eaten as a staple.
  • The FDA have never actually given soy protein isolate a GRAS (Generally Recognised as Safe) status due to concern regarding the presence of toxins and carcinogens in processed soy.
  • The Weston A Price Foundation (a non-profit nutritional organisation) in the United States are currently seeking to bring a class-action lawsuit against the soy industry on behalf of the many people who have developed hypothyroidism and sex hormone disruption due to consumption of even moderate amounts of soy.

Notes from October 2007

This is embarrassing to read back. Not because what I was saying was wrong, but because I’d become such a Weston A. Price Foundation nutcase that I was parroting their stuff. Although all of these facts are scientifically accurate, I probably sounded like a complete fruitcake.

I used to have such utter trust and faith in WAPF – despite having nothing but bad luck on their diet due to the sheer amount of amines it contains.

The truth is, soy is nasty stuff, but there are far nastier and more common food chemicals than the ones found in soy.
