In years past, I’d wait until October 30th before I hit the market for Halloween candy. But I now know that’s a sad trick, because conventional candy is full of food dyes: Blue 1, Red 40, Yellow 5, and Yellow 6, have all been linked to allergic reactions and behavioral problems in children. The only way to avoid these artificial food dyes is to buy USDA certified organic foods, which are guaranteed by our government not to contain synthetic ingredients. But organic Halloween candy has traditionally been hard to find—especially the night before the big day. Not anymore!
