Soy: One of the Worst “Foods” Commonly Consumed

by Bob McCauley, CNC, MH

“Health foods make promises that only the Second Coming could fulfill.” ~ Mason Cooley

One of the biggest mistakes a lot of vegetarians make is to consume soy.  When I first became a vegetarian in 1980, I went to a vegetarian cooking class at Lansing Community College.  The woman who taught was a fanatic about vegetarianism and was completely adamant about the necessity that vegetarians get their protein from soy.  She referred to it as a “near perfect food”.  I bought into that for a long time, but luckily did not consume a lot of soy in the following years.  What soy I did consume was a form of fermented soy called tempe.

Much has been promised to us from soybeans in the way of health.  Proponents claim that soy is a near perfect food with a large array of amino acids and other nutrients.  Soybeans are approximately 35% protein, only 58% that of Spirulina and Chlorella. Spirulina and Chlorella are five times easier to digest than meat, fish, eggs, dairy and soy protein.[i] Soy is rarely consumed raw unless it is sprouted.  Nearly all soybeans are eaten after they are processed into tofu, textured protein or fermented into foods such as tempeh.  Once you have cooked or processed any food, you have altered its natural chemical structure.  Heat is a chemical reagent that radically alters anything it comes in contact with.

Soy contains goitrogens, which block the synthesis of thyroid hormones and disrupt the assimilation of iodine.  Without iodine, the thyroid cannot regulate the body’s metabolism, which can lead to obesity, or the opposite.  Consuming fluoride will also interfere with the uptake of iodine, and consequently our metabolism.

Soy contains soyatoxin, phytates, protease inhibitors, oxalates – all of which interfere with the enzymes needed to digest protein.

Soy contains Trypsin Inhibitors: Trypsin allows for the digestion of protein.  Haemagglutinin and trypsin are growth inhibitors.

Soy contains Phytic Acid (phytate): Highest of any plant.  Inhibits the uptake of minerals into the body, such as calcium, magnesium, iron and zinc.

The energy footprint of soy is unlike any other food we commonly consume.  All raw foods contain negatively spinning ions, which are advantageous to the body.  However, soy contains positively spinning ions, which are counter-productive to our health, as are all positively charged particles.

There are plenty of other problems with soy and its negative effects on the body, such as it produces a lot of gas for many who consume it.  Other digestive problems often disappear when soy is removed from their diet, including infants.  Processed soy products are rich in phytohemaglutinin (PHG),[ii] a glue-like substance that unbalances the body chemistry, slows circulation and thickens the blood, numbing the immune and nervous systems.  Enzyme inhibitors found in soy interfere with the action of trypsin, a digestive enzyme that breaks down protein.  Soy also contains goitrogens, which suppress thyroid functions; phytic acid, which can block the absorption of essential minerals such as calcium, copper, magnesium, iron and zinc in the intestinal tract.[iii]

The high amount of manganese found in soy-based infant formulas, 200 times that of breast milk, can cause brain damage in babies and a slowing of brain functions in children.  One study concluded that the last thing women should do to prevent breast cancer is to consume soy.[iv] Another study showed accelerated brain aging in those who regularly consumed soy.[v] Women who are pregnant should avoid soy because of the risk of breast cancer.[vi] Soy has also been linked to pancreatic cancer.[vii] Soy can slow sexual performance because isoflavones interfere with estrogen function.[viii] It contains isoflavones genistein and daidzein which mimic estrogen.  They disrupt estrogen and glandular production. In one major study, Asian men who ate tofu increased their chances of getting Alzheimer’s Disease.[ix]

Although it is quite common, the consumption throughout Asia is highly overestimated.  The soy products they do eat tend to be fermented, which is less harmful.  There is no history of soy being consumed for health reasons anywhere in the world until the last half of the Twentieth Century.

The soy craze has been deliberately fueled by corporate propaganda that promotes commercial interests rather than health.  75% of all soy based products found on the market have been derived from genetically modified soybeans, some that have been crossed with nuts and other foods that cause tremendous allergic reactions in people.

Soy can be used as a transition food to move away from meat and other animal protein to plant protein, that of Spirulina and Chlorella. But once that bridge has been crossed, it must be burned and soy should be completely avoided.

Bob McCauley, ND (Robert F., Jr.) was raised in Lansing, Michigan and attended Michigan State University (BA, 1980 in Journalism). He is a naturopathic doctor, Master Herbalist and a Certified Nutritional Consultant. He has traveled extensively, both domestically and abroad, visiting over 32 countries. He published Confessions of a Body Builder: Rejuvenating the Body with Spirulina, Chlorella, Raw Foods and Ionized Water (2000), Achieving Great Health (2005), The Miraculous Properties of Ionized Water, (2006) which is the only book on the market that exclusively addresses Ionized Water, Twelve (Fiction, 2007) and Honoring the Temple of God (2008). He considers himself a Naturalist, meaning he pursues health in the most natural way possible. He studies and promotes nature as the only way to true health. From 2002-2004 he hosted the radio program Achieving Great Health, which was heard by thousands of people each day. His guests included some of the most well-known and respected names in the natural health world. With the help of his father, Dr. Robert F. McCauley, Sr. (Doctorate in Environmental Engineering, MIT, 1953) they started Spartan Water Company in 1992, which sold vended water machines in supermarkets. Robert Jr. founded Spartan Enterprises, Inc. in 1993. He is a Certified Water Technician with the State of Michigan. He is also a Type II Public Water Supply Specialist and has the certifications of S-5 and D-5. The McCauley family has a long history in the water industry. Bob's father pioneered environmental issues regarding ground water and drinking water quality. He received his Ph.D. from the Massachusetts Institute of Technology (MIT) in 1953 for his thesis on removing radioactive strontium from water. He earned his doctorate in Environmental Engineering in less than 2 years, one of the shortest doctoral studies in the history of MIT. He taught civil, sanitary and environmental engineering at Michigan State University for 18 years before retiring to run Wolverine Engineers & Surveyors of Mason, Michigan, for 17 years. His reputation throughout Michigan as a water quality expert was legendary. Bob worked for his father's company for 12 years learning the water business, which dealt primarily with municipalities, including water quality and sanitary sewer issues. After apprenticing with his father, Bob moved on to the bottled water business. He established greater Michigan's biggest selling bottled water: Michigan Mineral – Premium Natural Water. He was introduced to Ionized Water in 1995 and has done more to promote Ionized Water than anyone else in the industry. Bob often lectures and offers seminars on his Seven Component Natural Health Protocol . Bob is a Certified Nutritional Consultant and a Certified Master Herbalist. He is also a 3rd Degree Black Belt and Certified Instructor of Songahm Taekwondo (American Taekwondo Association).
