Six cancer-preventing dietary guidelines, from the Physicians Committee for Responsible Medicine, emphasize a diet rich in plant foods, and warn about the links between cancer and alcohol, red and processed meats, dairy, and meats cooked at high temperature, according to the June 30, 2014 issue of the Journal of the American College of Nutrition. The guidelines are based on the principle that diet changes are justified when evidence is substantial, even if not conclusive.

Kiwis vibrant green flesh with a dash of tropical flair has been coveted since it was discovered in its native China. Soon known as the Chinese gooseberry, New Zealand growers exported it around the world. A California produce dealer dubbed it kiwifruit in the 1960s because it resembled New Zealands national bird, the fuzzy brown kiwi! Today, California grows 98 percent of the U.S. supply of this beautiful and nutritious fruit.

Bisphenol A (BPA) is an industrial chemical used to produce polycarbonate plastic (clear, rigid, shatter-proof plastic) and epoxy resins. It is found in plastic containers, food and beverage cans, cash register receipts, some dental sealants and composites, medical devices, and other metal and plastic products. Exposure occurs when BPA leaches into foods, especially if containers are heated or washed with harsh detergents. It is estimated that 93 percent of Americans age 6 and over are exposed to BPA. The Food and Drug Administration (FDA) has declared that BPA is safe, despite concerns about the chemicals toxicity.
There has been a lot of negative talk about antinutrients in plant foods. So, what are antinutrients? They are compoundsfound naturally in whole grains, nuts, seeds, beans, and leafy greensthat may decrease nutritional value of foods by making the nutrients less available to your body. Antinutrients may sound scary, but theres no need to ditch these healthy plant foods from your diet. The simple act of preparing and cooking foods, such as grains and beans, helps to reduce antinutrient content and improve the availability of nutrients. Also, since a varied, balanced diet provides more than enough nutrients, the small loss due to antinutrients isnt a problem.
