A Fresh Squeeze

Drinking one glass of orange juice daily has been found to cut your odds of developing inflammatory arthritis conditions (like rheumatoid arthritis) just about in half, says Richard Mayfield, DC, certified clinical nutritionist and faculty doctor at The Institute for Functional Medicine. And studies show that citrus fruits are a good source of carotenoid antioxidants. However, there's one big asterisk: Fruit juices contain sugar (one cup can have 21 grams and none of the natural fruit fiber that can blunt the resulting blood-sugar spikes and dips. In the context of an otherwise healthy diet, Mayfield says, drinking some juice is fine, as long as you don't eat too much added sugars. But for the majority of us, even drinking just a small amount can be beneficial.
