Myth # 10 Soy products are adequate substitutes for meat and dairy products.

MYTH #10:

Soy products are adequate substitutes for meat and dairy products.

The billion-dollar soy industry has profited immensely from the anti-cholesterol, anti-meat gospel of current nutritional thought. Whereas, not so long ago, soy was an Asian phenomenon, now soy products proliferate in the North American market. While the traditionally fermented soy products of miso, shoyu, tempeh and natto are definitely healthful in measured amounts, the hyper-processed soy “foods” are not.

Non-fermented soybeans are extremely high in phytic acid (54), an anti-nutrient that binds to minerals in the digestive tract and carries them out of the body. Vegetarians are known for their high rates of iron and zinc deficiencies (55).

Soybeans are also rich in trypsin inhibitors, which hinder protein digestion. Textured vegetable protein (TVP), soy “milk” and soy protein powders, and popular vegetarian meat and milk substitutes are entirely fragmented foods made by treating soybeans with high heat and various alkaline washes to extract the beans’ fat content or to neutralise their potent enzyme inhibitors. These practices completely denature the beans’ protein content, rendering it very hard to digest. MSG, a neurotoxin, is routinely added to TVP to make it taste like the various foods it imitates (56).

On a purely nutritional level, soybeans, like all legumes, are deficient in cysteine and methionine, vital sulphur-containing amino acids (56). Soybeans are also lacking in tryptophan, another essential amino acid (56).

Furthermore, soybeans contain no vitamins A or D, required by the body to assimilate and utilise the beans’ proteins (56). It is probably for this reason that Asian cultures that do consume soybeans usually combine them with fish or fish broths, The New Zealand government is considering removing soy formula from the market and making it available only by prescription (58).

Though research is still ongoing, some recent studies have indicated that soy’s phyto-oestrogens could be causative factors in breast cancer and infantile leukaemia (59). Regardless, soy’s phyto-oestrogens, or isoflavones, have been shown to depress thyroid function and cause infertility in some animals (60). As a practitioner, I have seen more than my share of vegetarians with hypothyroidism. They invariably rely on soy foods to get their protein.

MYTH #7: Vegetarians live longer and have more energy and endurance than meat-eaters.

MYTH #7:

Vegetarians live longer and have more energy and endurance than meat-eaters.

Surprising as it may seem, some prior studies have shown the annual all-causedeath rate of vegetarian men to be slightly more than that of non-vegetarian men (0.93% vs 0.89%). Similarly, the annual all-cause death rate of vegetarian women was shown to be significantly higher than that of non-vegetarian women (0.86% vs 0.54%). (40)

Russell Smith, PhD, referred to in myth # 5, in his authoritative study on heart disease, showed that as animal product consumption increased among some study groups, death rates decreased! Such results were not obtained among vegetarian subjects. For example, in a study published by Burr and Sweetnam in 1982, analysis of mortality data revealed that, although vegetarians had a slightly (.11%) lower rate of heart disease than non-vegetarians, the all-cause death rate was much HIGHER for vegetarians (41).

It is usually claimed that the lives of predominantly meat-eating peoples are short-lived, but the Aborigines of Australia, who traditionally eat a diet rich in animal products, are known for their longevity (at least before colonisation by Europeans). Within Aboriginal society, there is a special caste of the elderly (42). Obviously, if no old people existed, no such group would have existed. In his book Nutrition and Physical Degeneration, Dr. Price has numerous photographs of elderly native peoples from around the world (42). Explorers such as Vilhjalmur Stefansson reported great longevity among the Inuit (again, before colonisation). (43)

Similarly, the Russians of the Caucasus mountains live to great ages on a diet of fatty pork and whole milk products. The Hunzas, also known for their robust health and longevity, eat substantial portions of goat’s milk which has a higher saturated fat content than cow’s milk (44). In contrast, the largely vegetarian inhabitants of southern India have the shortest life-spans in the world (45). Dr Weston Price, DDS, travelled around the world in the 1920s and 1930s, investigating native diets. Without exception, he found a strong correlation among diets rich in animal fats, with robust health and athletic ability. Special foods for Swiss athletes, for example, included bowls of fresh, raw cream! In Africa, Dr Price discovered that groups whose diets were rich in fatty fish and organ meats, like liver, consistently carried off the prizes in athletic contests, and that meat-eating tribes always dominated peoples whose diets were largely vegetarian (42).

It is popular in sports nutrition to recommend “carb loading” for athletes, to increase their endurance levels. But recent studies done in New York and South Africa show that the opposite is true: athletes who “carb loaded” had significantly less endurance than those who “fat loaded” before athletic events
