Because flesh is high on the food chain, it often contains unacceptable levels of environmental contaminants. All over the world, poisonous chemicals are buried in the ground or dumped in lakes, rivers, and the sea. Pesticides and herbicides are used in growing food crops and accumulate in the soil. Growing plants absorb small amounts of these chemicals. Because they are highly attracted to and absorbed by fat, these chemicals are called fat-soluble. When animals and fish eat plants containing even low levels of contaminants, these chemicals are concentrated in the fatty tissues of their bodies. If we consume the flesh of these polluted creatures, we take in large amounts of potentially harmful substances. Animal flesh is further contaminated by the wide variety of drugs used in livestock yards. These drugs include hormones, stimulants, and antibiotics. They are used to speed animal growth and to combat the infectious diseases commonly found in such crowded conditions. When we eat meat and poultry grown under such circumstances, we consume an assortment of animal powerful drugs.
――中略―― Dairy products are high on the food chain and therefore may contain unsafe levels of environmental contaminants. Even human mother's breast milk can contain dangerous amounts of these substances. An infant, being at the top of the food chain, gets the highest levels of these environmental chemicals. The Environmental Defense Fund studied the breast milk of 1400 women from forty-six states. This study found widespread contamination were twice as high in meat and dairy-consuming woman as in vegetarians. Because pesticides are concentrated in animal foods, the study advised “women who expect to breast feed their babies to avoid meat, some kinds of fish, and high-fat dairy products."
