Some juice cleanse companies claim say their programs can cure conditions like type 2 diabetes, fibromyalgia, or even acne. Don't buy it. Not only is it illegal to make disease claims for any product that's not an FDA-approved drug, there's just no science to back them.
What juice cleansing can do, however, is put you on a path to better health. By eliminating toxin-packed foods for a stretch and then, after your cleanse, sticking to mostly whole foods, you'll help get your body in prime working order. That's what can help clear up skin, ease aches and pains, and get blood sugar levels back on track.
