If you saw "poison ivy" listed as an ingredient in your favorite salad mix, would you eat it? Probably not. But poison ivy is natural, right? Who cares if it gives you a heinous rash and makes you miserable? The food industry might as well apply the same logic to all the other so-called "natural" ingredients it tries to sneak into processed foods.
Ingredients made from seaweed, palm trees, and fruit juice may have a healthy halo, but they actually come with more health risks than benefits--no matter how natural they sound.
