I suspect many. Green tea is great for you, and is a potent source of antioxidants. I endorse eating or drinking foods rich in these. So good for you, but what about arthritis. No studies exist, but as i said, its good for you in many ways. Conceptually, it might actually help. But no studies exist to show that.
Overhyped. Green tea is the latest in a long line of overhyped nutritional products. Claims include weight loss, better health, longer life, better endurance. Do not believe the hype. Yes green tea contains some anti-oxidants and phytonutrients, but it still contains caffiene which is a stimulant and has diuretic properties. Too much green tea is not good for you.
