Gelatin

If you’re thinking about wiggly, jiggly Jello, you’re right. Gelatin is derived from collagen, and both are protein-packed. Overall, gelatin holds several health benefits, but you’ve got to be cautious about the type you buy. Gelatin is made from dehydrating the skin, bone, and connective internal tissue from animals.

Like all animal byproducts, gelatin is only as good as the animal it’s from, which means buying quality products. Poor-quality gelatin can contain trace amounts of lead and other harmful chemicals the animal may have eaten.
