The U.S. Dietary Guidelines recommend that women 50 and older eat at least 22 grams per day, and men at least 28. Some research suggests that even more is better: In one study, eating 30 grams of fiber per day was nearly as effective for weight loss as cutting out sugar, fat, salt and alcohol. But the average American consumes a mere 18 grams per day. How can we do better? High-fiber cereals and lots of beans can get you there, but maybe eating like a rabbit or a cowboy isn’t for you. Here are some other ways to boost your intake.
