Soy: A Secret Source of Aggression
One of the nation’s most powerful industries, in terms of political power and lobbying influence, is the soy industry.
Soybeans are grown in unbelievable quantities all over the world. And based on early reports of the potential for one of soy’s chemical components, genistein, to inhibit cancer growth (especially breast cancer), the number of soy products has exploded. Women, especially, are consuming, Soy-based milk, Soy foods, Soy-based snacks In fact, soy has become something of an American obsession.
But here is some important research the mainstream media will never report. In a 2004 study, researchers used Syrian hamsters to determine the effect of a soy-based diet on aggressiveness.
They found that the animals that were fed the soybased diet became more aggressive and had higher
testosterone levels compared to animals that were fed a soy-free diet. Another study found that rats which were fed a soy-based diet were less sociable than rats on soyfree diets. Researchers also found that the soy-fed
rats tolerated stress less well, and were more anxious than their soy-free counterparts. The soy-fed rats also produced significantly more cortisol with stress, excess cortisol damages the hippocampus the part of the brain concerned with memory, learning, and behavior.
In 2004, Neal Simon, a professor of behavioral neuroscience, and his co-workers tested long-term, soy-based diet (including high- and medium dose soy protein isolates) against soy-free diets in monkeys. After 15 months on the respective diets, the soy-fed monkeys were significantly more aggressive and tended to be antisocial. There was no increase in testosterone levels.
What about soy’s cancer-inhibiting properties? More recent reports have shown that genistein, the so-called anti-cancer compound found in soy foods, causes fragmentation of DNA in rats eating both low- and high-dose soy diets. Fragmented DNA can lead to cancer and worsening of neurodegenerative
brain diseases such as Alzheimer’s.
Unfortunately, no studies have been done to address soy’s effects on depression and suicide risk.
But there are several studies that implicate soy in these disorders. For example, rats that were fed a soy-based diet (in doses less than what humans consume) showed significant reductions of the brain growth factor BDNF (brain-derived neurotrophic factor) within the hippocampus and the cerebral cortex. Low BDNF was also found in cases of suicide and major depression.
Considered together, these studies should generate major concern over consuming soy products , especially soy milk, as toxic compounds in liquid forms are more rapidly absorbed. Even the American Academy of Pediatrics expressed concern about the high levels of toxic manganese in soy baby formula. (Manganese, like
aluminum, activates brain inflammation and can cause severe brain damage.)
But because of the powerful political interests involved with the soy industry, adult consumption
of soy products continues unabated, and mostly unexamined.
Soy-Based Baby Formula is a Bad Idea
Exposing infants to isoflavones by feeding them soy-based infant formula can have harmful effects.
In one study, infant girls fed soy formula had significantly more breast tissue at 2 years of age than those who were fed breast milk or dairy-based formula.
Another study showed that girls fed soy formula were much more likely to go through puberty at a younger age.
There is also evidence that soy formula during infancy can lead to a lengthening of the menstrual cycle and increased pain during menses in adulthood.
Soy is also very high in manganese, MUCH higher than breast milk, which may lead to neurological problems and ADHD . Soy infant formula is also high in aluminum, which can cause all sorts of problems.
There is no question about it… breast milk is by far the best nourishment for babies. For women who can not breastfeed, milk-based formula is a much better option than soy-based formula, which should only be used as a last resort.
Bottom Line: There is significant evidence that soy-based infant formula can cause harm, both via its isoflavone content and its unnaturally high content of manganese and aluminum.
