[sidebar]Pass on GM produceWhile the impact of genetically modified foods on humans is unknown, some preliminary animal studies suggest that these items could cause food allergies and certain diseases. To spot genetically tweaked produce, look at the PLU code on the sticker. Conventional produce uses a 4-digit number starting with 3 or 4, organic uses a 5-digit number starting with 9, and genetically modified uses a 5-digit number starting with 8. A genetically modified zucchini, for example, has the code 84067. (Confused about GM products? Here’s what you need to know.) Pick the right packagingMilk in opaque or cardboard cartons contains more micronutrients than milk in clear jugs. That’s because some vitamins are sensitive to light. Researchers at Cornell University found that up to 20% of the vitamin A in fat-free milk was lost after 2 hours of fluorescent light exposure. Vitamin C and vitamin B2 (riboflavin) also break down when exposed to light. Opt for blocks of cheeseNot familiar with cellulose powder? This ingredient in nearly all shredded cheese is really wood pulp, which contains an indigestible fiber that absorbs moisture in packaging to extend shelf life. Buy cheese the way it’s traditionally made—as a block. Right before you eat it, cut, shred, or crumble it yourself to lock in micronutrients and protect yourself from additives.
