Gross Food #5: Grain productsWhy it’s gross: Many packaged breads and baked goods contain L-cysteine—a non-essential amino acid made from dissolved human hair (often from China) or duck feathers (mmmm). Food manufacturers use the ingredient as a commercial dough conditioner, meant to improve the texture of breads and baked goods.
Why it’s bad: Eating something derived from the human body violates the religious and ethical beliefs of Muslims and vegans. Plus, eew! If you want to avoid ingesting hair and feathers—and really, who doesn’t?—try eating unprocessed whole grains like oats and brown rice, and make your own baked goods whenever possible.
