How Much Fiber Do You Need?

The generally recommended fiber intake for adults is 25 to 40 grams per day, depending on caloric intake (12.5 grams per 1,000 calories consumed), but Joslin’s new nutritional guidelines recommend eating at least 50 grams of fiber a day, which is extremely optimistic given that most people don’t even meet the currently recommended levels.

Instead of getting caught up in trying to eat a certain amount of fiber daily, make it easier on yourself by simply making a steadfast commitment to eat more whole grains, fruits, vegetables, and legumes; your fiber intake will greatly increase (maybe even up to 50 grams a day).
