Lately the hottest thing since sliced bread seems to be, well, pretty much the opposite of that. Gluten-free products have been popping up on supermarket shelves across the country, appealing to those with Celiac disease or gluten intolerance, as well as other health-conscious eaters. "In my practice I've seen that cutting back on gluten can lead to the elimination of irritable bowel syndrome and heartburn, fewer headaches, better mental focus, less fatigue, resolution of sinus congestion, better skin, and better mood," says Dr. Arthur Agaston, author of The South Beach Diet Gluten Solution Cookbook.
However, he cautions that going gluten-free won't necessarily lead to weight loss. The refined, low-fiber foods linked to weight gain, obesity, and diabetes are just as common in gluten-free products as they are in their conventional counterparts, Agaston says. Instead he urges people to choose naturally high-fiber, low-glycemic, gluten-free foods. The following healthy snacks are low in calories but provide ample protein and fiber to ward off hunger--and unwanted pounds.
