Thirsty? Beware: These Foods And Drinks Will Dehydrate You

Why Detox Teas Are Worse Than Regular Teas

Most teas will hydrate you, but “detox,” “cleansing,” or “weight loss” teas may not. These teas mix caffeine with other substances to create a laxative effect. The Natural Medicines Comprehensive Database claims that these teas can cause diarrhea and dehydrate you.

Before you buy a detox tea, research the side effects. You might lose more water than weight. General practitioners Dr. Louise Newson adds that the FDA does not regulate these teas. If you want to rehydrate, aim for a tea that IS regulated–green teas, black teas, and herbals.
