Soy -- The Reality Behind the Bean

I've been arguing against soy for years due to its many health issues. Here is another article calling its health claims into question, from the Guardian Unlimited.

In the West, we have not only neutralized any healthy qualities in soy, we have made the unhealthy aspects more pronounced. Here is an explanation, from the article, of how soy is used in Asian countries:

Dawson describes the traditional craft method of transforming the soya bean through fermentation, so that its valuable amino acids become available but its antinutrients are tamed. The process involves cooking whole soya beans, complete with their oil, for several hours, then adding the spores of a mould to the mix, and leaving it to ferment for three days to begin the long process of breaking down the proteins and starches. This initial brew is then mixed with salt water and left to ferment for a further 18 months, during which time the temperature will vary with the seasons. The end result is an intensely flavoured condiment in which the soya's chemical composition has been radically altered. Traditional miso is similarly made with natural whole ingredients, slowly aged.

The basic idea is that fermented soy is okay, all the rest is crap, or worse....

Should we worry about soya in our food? 

Whether you know it or not, you'll probably be eating soya today. It's in 60% of all processed food, from cheese to ice cream, baby formula to biscuits. But should it carry a health warning? Felicity Lawrence investigates

For Dr Mike Fitzpatrick, the saga of soya began in Monty Python-style with a dead parrot. His investigations into the ubiquitous bean started in 1991 when Richard James, a multimillionaire American lawyer, turned up at the laboratory in New Zealand where Fitzpatrick was working as a consultant toxicologist. James was sure that soya beans were killing his rare birds.

"We thought he was mad, but he had a lot of money and wanted us to find out what was going on," Fitzpatrick recalls.

Over the next months, Fitzpatrick carried out an exhaustive study of soya and its effects. "We discovered quite quickly," he recalls, "that soya contains toxins and plant oestrogens powerful enough to disrupt women's menstrual cycles in experiments. It also appeared damaging to the thyroid." James's lobbying eventually forced governments to investigate. In 2002, the British government's expert committee on the toxicity of food (CoT) published the results of its inquiry into the safety of plant oestrogens, mainly from soya proteins, in modern food. It concluded that in general the health benefits claimed for soya were not supported by clear evidence and judged that there could be risks from high levels of consumption for certain age groups. Yet little has happened to curb soya's growth since.

More than 60% of all processed food in Britain today contains soya in some form, according to food industry estimates. It is in breakfast cereals, cereal bars and biscuits, cheeses, cakes, dairy desserts, gravies, noodles, pastries, soups, sausage casings, sauces and sandwich spreads. Soya, crushed, separated and refined into its different parts, can appear on food labels as soya flour, hydrolysed vegetable protein, soy protein isolate, protein concentrate, textured vegetable protein, vegetable oil (simple, fully, or partially hydrogenated), plant sterols, or the emulsifier lecithin. Its many guises hint at its value to manufacturers.

Soya increases the protein content of processed meat products. It replaces them altogether in vegetarian foods. It stops industrial breads shrinking. It makes cakes hold on to their water. It helps manufacturers mix water into oil. Hydrogenated, its oil is used to deep-fry fast food.

Soya is also in cat food and dog food. But above all it is used in agricultural feeds for intensive chicken, beef, dairy, pig and fish farming. Soya protein - which accounts for 35% of the raw bean - is what has made the global factory farming of livestock for cheap meat a possibility. Soya oil - high in omega 6 fatty acids and 18% of the whole bean - has meanwhile driven the postwar explosion in snack foods around the world. Crisps, confectionery, deep-fried take-aways, ready meals, ice-creams, mayonnaise and margarines all make liberal use of it. Its widespread presence is one of the reasons our balance of omega 3 to omega 6 essential fatty acids is so out of kilter.

You may think that when you order a skinny soya latte, you are choosing a commodity blessed with an unadulterated aura of health. But soya today is in fact associated with patterns of food consumption that have been linked to diet-related diseases. And 50 years ago it was not eaten in the west in any quantity.
