18. Big brand peanut butter
Peanut butter should be made from peanuts and salt — that’s it. However, in an effort to cut costs, some cheaper big brands of peanut butter contain ingredients like added sugar and soybean oil. The added sugar is totally unnecessary, of course, and the soybean oil is almost always derived from GMO soy. If you love peanut butter, check your ingredient labels, and try to buy peanut butter that’s just that: peanut butter. Otherwise, it’s sugary peanut spread.
