10. Bread and 11. Crackers Made With Potassium Bromate: This chemical is used to help bread and cracker dough rise during the baking process — even though it’s been linked to certain cancers in animal studies and it’s banned in many other countries.
That’s good enough reason for Leiba to recommend against eating it. Look for the ingredient on baked good labels or ask about it at the bakery where you buy *fAnCy~* freshly made breads — then choose a potassium-bromate-free option, when you can.
12. Microwave Popcorn: “It’s not healthy eating out of a bag anymore,” Rifkin says. Microwave popcorn bags, in particular, are often lined with a chemical called perfluorooctane sulfonic acid (PFOS), which has been shown to affect fertility, cancer risk, and kidney functioning in animal and some human studies. Because microwave popcorn bags aren’t labeled “toxic,” it’s best to avoid them altogether. Another thing:
Some brands of microwave popcorn add unhealthy trans fats to their products, and vaguely list “artificial flavors” or “natural flavors” on their labels — so there’s no way to know exactly what’s in there, Warren warns. In the worst case scenarios, the recipe could contain MSG, which can cause headaches or nausea, or diacetyl butter flavoring, which may cause respiratory damage when inhaled. (Air popped, anyone?)
