We've gone over the dirty dozen produce to avoid and the food containers to shun in your house. But according to researchers, the USDA and other food experts, there are seven foods in particular that they wouldn't even touch. From potatoes to microwave popcorn, start off the new year right by avoiding the foods on this important list.1. Canned Tomatoes: "The resin linings of tin cans contain bisphenol-A, a synthetic estrogen that has been linked to ailments ranging from reproductive problems to heart disease, diabetes, and obesity."
2. Corn-Fed Beef: "Cattle evolved to eat grass, not grains. But farmers today feed their animals corn and soybeans, which fatten up the animals faster for slaughter... Compared with corn-fed beef, grass-fed beef is higher in beta-carotene, vitamin E, omega-3s, conjugated linoleic acid (CLA), calcium, magnesium, and potassium; lower in inflammatory omega-6s; and lower in saturated fats that have been linked to heart disease."
3. Microwave Popcorn: "Chemicals, including perfluorooctanoic acid (PFOA), in the lining of the bag, are part of a class of compounds that may be linked to infertility in humans, according to a recent study from UCLA. In animal testing, the chemicals cause liver, testicular, and pancreatic cancer. Studies show that microwaving causes the chemicals to vaporize-and migrate into your popcorn."
4. Nonorganic Potatoes: "Root vegetables absorb herbicides, pesticides, and fungicides that wind up in soil. In the case of potatoes-the nation's most popular vegetable-they're treated with fungicides during the growing season, then sprayed with herbicides to kill off the fibrous vines before harvesting. After they're dug up, the potatoes are treated yet again to prevent them from sprouting... I've talked with potato growers who say point-blank they would never eat the potatoes they sell. They have separate plots where they grow potatoes for themselves without all the chemicals."
5. Farmed Salmon: "Farmed salmon is lower in vitamin D and higher in contaminants, including carcinogens, PCBs, brominated flame retardants, and pesticides such as dioxin and DDT... The most contaminated fish come from Northern Europe, which can be found on American menus."
6. Milk Produced with Artificial Hormones: "Milk producers treat their dairy cattle with recombinant bovine growth hormone (rBGH or rBST, as it is also known) to boost milk production. In people, high levels of IGF-1 may contribute to breast, prostate, and colon cancers."
7. Conventional Apples: "They are individually grafted (descended from a single tree) so that each variety maintains its distinctive flavor. As such, apples don't develop resistance to pests and are sprayed frequently."
