7.Isoflavones
They’re also called phytoestrogens, because they behave like the hormone estrogen when they’re in a human body. Some women going through menopause use isoflavones as a way to ease symptoms like hot flashes. Soy products like tofu and edamame are the richest sources.
8.Capsaicin
It puts the heat in cayenne and other spicy peppers. Capsaicin creams are used to relieve pain from arthritis, fibromyalgia, and some types of nerve damage as well as psoriasis itching. It’s also being studied as a way to fight cancer, help with weight loss, and — ironically — treat heartburn.
