Potatoes

One of the most widely grown foods in the Western world is the potato. They belong to the family of perennial nightshades, which under some circumstances can be slightly toxic. Any green skin or flesh, including the "eyes" or sprouts of potato, are likely to contain the toxin solanine. However, solanine is also present in non-green portions of the potato. Solanine may be found in potatoes that are: picked too early; exposed to light; stored someplace too cold, like the fridge.

Fortunately, potatoes tend to have less toxicity when they are cooked and peeled. Potatoes are a wonderful source of vitamin C, a vitamin that supports immunity. They are a more nutritious staple than you may think because they are also a strong source of potassium, vitamin B-6, and fiber. According to the USDA, they also include carotenoids, flavonoids, and caffeic acid, which are all types of phytonutrients known to support health benefits.
