1. Canned Tomatoes
The Expert: Fredrick vom Saal, PhD, an endocrinologist at the University of Missouri who studies bisphenol-A.
The Situation: 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. Unfortunately, acidity (a prominent characteristic of tomatoes) causes BPA to leach into your food. Studies show that the BPA in most people’s body exceeds the amount that suppresses sperm production or causes chromosomal damage to the eggs of animals. “You can get 50 mcg of BPA per liter out of a tomato can, and that’s a level that is going to impact people, particularly the young,” says vom Saal. “I won’t go near canned tomatoes.”
The Answer: Choose tomatoes in glass bottles (which do not need resin linings), such as the brands Bionaturae and Coluccio. You can also get several types in Tetra Pak boxes, like Trader Joe’s and Pomi.
2. Corn-Fed Beef
The Expert: Joel Salatin, co-owner of Polyface Farms and author of half a dozen books on sustainable farming.
The Situation: Cattle evolved to eat grass, not grains. But farmers today feed their animals corn and soybeans, which fatten up the animals faster for slaughter. More money for cattle farmers (and lower prices at the grocery store) means a lot less nutrition for us. A recent comprehensive study conducted by the USDA and read the rest of this story..
