Are saponins really good for you?

Saponins are found on over 100 plants, which we eat, including spinach, herbs, peas, oats, beans, lentils, soybeans, quinoa, the edible skin of fruits like grapes, and even in root vegetables, like sweet potatoes and yams – they’re everywhere!

But in very tiny, miniscule amounts.

They’re antibacterial and toxic to cold-blooded living things, like insects, but not to humans.

If you think of it, all plants, each and every one of them, have some form of defense mechanism to survive toxic living things and grow. And phytochemicals are a key in that – deadly for some insects and pathogens, but beneficial for us.

Remember, phytochemicals get rid of destructive pathogens in your body (in the same way they detract bad bacteria and toxic living things in plants). This relieves stress on your immune system and protects your cells and DNA from being damaged.

Saponins are considered safe in humans, and isolated and used in mega doses in pharmacological products, including some vaccines and now in the development of anti-cancer medicines.
