In one section, Ms. Allport quotes from Corinne Shear Wood, Human Sickness and Health: A Biocultural View, "good nutrition does not inevitably guarantee good health. Poor nutrition, however, always produces poor health." Wow.
Allport's argument is that food production in this country has been geared toward providing an abundance of cheap foods, which are not as cheap as they may seem if they are harming our health. If, in fact, as she argues "these foods do no meet all of our nutrition needs and that the health costs associated with these foods mean they are far from cheap." One major example is the move to feedlots and commercial use of corn to feed steer, in lieu of the grass these animals naturally eat. In essence, this argument is that the meat we eat today is inherently different than the meat of the grass-grazing steer of yesteryear. This is something Michael Pollan has been saying for years and which even George Will has acknowledged (Washington Post, Sunday March 8, 2009). Michael Pollan says "you are what what you eat eats, too."
I've mentioned many foods and recipes on this blog that are high in Omega-3: salmon, walnuts, leafy green vegetables, cauliflower, cabbage. Other foods that include Omega-3s are flaxseed and tofu and many other fruits and vegetables.
