Liz Vaccariello, Editor in Chief of Prevention Magazine, recently interviewed several experts on food healthfulness and safety. She asked, “What foods do you avoid”, and was surprised by some of the answers.
1. Canned Tomatoes, Canned Soup, Canned Green Beens Recently, Consumer Reports magazine found the chemical bisphenol-A (BPA) in the resin lining of many common food brands. BPA is used for food preservation, but is a synthetic estrogen that has been linked to many illnesses including heart disease, diabetes, and reproductive issues. Consumer Reports found the highest levels to be in canned green beans and soups. Fredrick vom Saal, PhD, an endocrinologist at the University of Missouri who studies bisphenol-A (BPA) states that acidic foods such as tomatoes can also cause the BPA to leach into the food, at a rate that exceeds 50 micrograms per liter. Dr. Vom Saal recommends choosing tomatoes in glass bottles or Tetra Pak boxes.
2. Corn-Fed Beef Cows evolved eating grass, but today’s farmers feed their animals corn and soybeans, which fatten the animals faster for slaughter. A recent study conducted by the USDA and researchers from Clemson University found that corn-fed beefis lower in beta-carotene, vitamin E, omega-3 fatty acids, calcium, magnesium, and potassium than grass fed beef. It is also higher in saturated fat. A study from Purdue University found that corn fed beef contains higher levels of omega-6 fatty acids, which may encourage inflammation in the body and may lead to bone loss. Grass-fed beef can be found at specialty grocers, farmers markets, and nationally at Whole Foods.
3. Microwave Popcorn A big danger from microwave popcorn is burns from the steam that escapes when the bag is opened. Two chemicals in microwave popcorn have been linked to serious illness. In January 2008, the top four manufacturers removed diacetylas a butter-flavoring agent in the products because it was linked to lung injuries. ConAgra Foods, General Mills, and the American Pop Corn Company (that sells Orville Redenbacker, Act II, Pop Secret and Jolly Time) have changed their recipes to exclude diacetyl.
More recently, chemicals such as perfluorooctanoic acid (PFOA) have been found to be a part of the lining of the bag, which leaches into the food during microwave cooking. This chemical has been linked to infertility in a recent study from UCLA. In animal testing, the chemicals are linked to liver, testicular, and pancreatic cancer. Olga Naidenko, PhD, a senior scientist for the Environmental Working Group, says “[PFOA] stay in your body for years and accumulate there.” Some larger manufacturers have promised to phase out PFOA by 2015 under a voluntary EPA plan, but until then it is best to make popcorn using canola oil in a covered saucepan or skillet.
4. Nonorganic Potatoes and Carrots Root vegetables absorb the pesticides that wind up in the soil. In the case of potatoes, they are also treated with fungicides during the growing season, then sprayed with herbicides to kill off the fibrous vines before harvesting. The potatoes are treated once more at the processing plant to delay sprouting. Jeffrey Moyer, chair of the National Organic Standards Board, says that washing will not remove all the chemicals that have been absorbed into the flesh of the vegetables, and encourages the purchase of organic produce.
5. Farmed Salmon Salmon is promoted as one of the healthiest foods for the heart because it contains high levels of omega-3 fatty acids. However, when choosing salmon, it is best to choose wild-caught Alaska salmon over farmed salmon. Farmed salmon has been shown to contain 10 times more toxins, including Polychlorinated biphenyls (PCB) and dioxin, than wild salmon. Farmed salmon are fatter, and the PCBs are sequestered into the fat and remain there. In addition, salmon farms can harbor parasites, such as sea lice and kudoa thyrsites, so fishers use pesticides and antibiotics that can become part of your fish dinner. Many industrial salmon farms use artificial colorings to make the fish more appealing to consumers, some of which can be harmful to health.
If a package says fresh Atlantic salmon, it is likely farmed, according to David Carpenter, MD, director of the Institute for Health and the Environment at the University at Albany and publisher of a major study in the journal Science on contamination in fish. He states there are no longer commercial fisheries for wild Atlantic salmon.
6. Milk Produced with Artificial Hormones Rick North, project director of the Campaign for Safe Food at the Oregon Physicians for Social Responsibility, encourages the purchase of hormone-free or organic milk. Conventional milk farmers treat their dairy cattle with recombinant bovine growth hormone (rBGH or rBST) to boost milk production. These can lead to a higher level of a hormone in the casein called insulin-like growth factor (IGF-1) in humans that is linked to breast, prostate, and colon cancer. Organic milk farmers cannot use artificial hormones in their dairy cattle. Other manufactures may list rBGH-free or rBST-free on the package label.
7. Nonorganic Apples and Pears Many fruits are treated with pesticides. Those in which the peeling or skin is consumed are at highest risk to people. Over time, farming techniques for fruits such as apples have caused the fruit to lose its resistance to pests, and therefore they are sprayed more frequently. Washing the fruit thoroughly and removing the skin is recommended, but this may not eliminate the chemical residue entirely. In addition, removing the peeling removes many of the healthful benefits of fruit, such as fiber. According to the Daily Green, the best fruits to buy organic include apples, pears, grapes, and cherries.

This is an excellent article shedding light on many of the foods not commonly considered unhealthy.
Farm raised fish and corn fed beef are often overlooked. People generally do not consider the source of their animal foods.
Other foods that should be added to the list include:
- Packaged or processed foods
- Non-organic produce
- Dairy (from corn fed cows – even if it is organic)
- Foods containing hydrogenated fats (trans fat)
- High fructose corn syrup
- Pasteurized juices
Following these simple rules can help you steer clear of poor food choices:
- Limit eating out as much as possible
- If the ingredient label has any words that you cannot pronounce without a chemistry degree avoid it.
- Buy your produce when it is in season (locally if possible)
- Grocery shop for your next meal, not for the next two weeks. Foods should be perishable. Buy and eat them as fresh as possible.
- Before you eat, ask yourself the following questions:
Is this food healthy? Am I really hungry?
Remember, your body and your health are gifts from God. Don’t desecrate your temple!
