I had just finished reading In Defense of Food (the same author wrote The Omnivore's Dilemma). I shared some of the information that the author provided that had stayed with me. He provided many studies that show that no matter where it is introduced the "Western Diet" always leads to health problems and is completely unsustainable by any culture. By Western Diet he was summing up how many Americans eat in our day. He cited the French diet as being one that shouldn't work--they eat tons of butter in their pastries and drink lots of wine, but the flip side is that the French don't consider eating seconds--apparently it's anathema for them. He also cited other cultures that consume much more meat than we do yet still don't suffer from the problems that we do. How could that be? Well, while various other cultures may consume more meat, they are also typically people who are more active and are killing the meat they consume--a connection to the land--a circle of life type idea. Even the Mediterranean diet which has gained huge popularity in recent years is not perfect--it's high in oils and the Mediterranean people of the time period who were considered so physically fit were much more physically active than their predecessors.
One of the reasons Mr. Pollan believes that we are suffering from so many health problems is that we aren't eating real food. Did you know that margarine used to be colored red/pink to differentiate it from butter? Well, once the food industry was able to get that removed and also the label of processed foods, it's been all downhill for our American diet ever since. He said that if you were to go shopping at look at the aisles of food, hardly any of it really is "food." He said that for many Americans we would have to look at food from the viewpoint of our grandparents and even great-grandparents. Would they look at what we are looking at and recognize it as food?
So, you think soy is so wonderful for replacing your dairy? Did you know that all that estrogen found in so many soy products is causing adverse effects on our bodies? Boys are developing later in life and men that consume large amounts of soy (milk on your cereal, in your smoothie, tofu) start to experience hormonal imbalances and other health issues. I found this paragraph (from Men's Health) quite startling:
A whopping 35 percent of bottle-fed babies in the United States receive at least some of their protein from soy. The American Academy of Pediatrics (AAP) is taking steps to change this: It recommends that all infants who cannot be breastfed be given cow's-milk formulas as the first preferred alternative. Healthy full-term infants should be given soy formula only when medically necessary, the AAP's 2008 report states. Babies with an extreme form of lactose intolerance fall into this category, but many others who suffer from colic and excessive crying are switched to soy formula despite a lack of proven benefits.
Paul Cooke, Ph.D., a reproductive biologist at the University of Illinois, has studied mice raised on enough genistein to make their blood levels comparable to those of human infants fed soy formula. Among other worrisome findings, he discovered significant shrinkage of the thymus gland, a key part of the immune system. "The thymus," says Cooke, "is like a finishing school for white blood cells—it's where they go to mature."
Whether the same effect occurs in human infants is difficult to say, but a 2001 study in the Journal of the American Medical Association surveyed over 800 adults, ages 20 to 34, who were fed either soy-based or cow's-milk formulas during their infancy. One of the few differences to emerge was that the group raised on soy formula regularly used more asthma and allergy medications in adulthood. Was this just a quirk of the sampling—or could it represent a subtle impairment of immune function?
