According to WebMD, “How much fiber do you need? Women need 25 grams per day and men should get 38 grams per day, according to an Institute of Medicine formula based on getting 14 grams of fiber for every 1,000 calories.” Unfortunately, most Americans eat less than half of the recommended amout.
There are both soluble and insoluble fibers. Both types are good for your health and have been proven to reduce the risk of various types of cancer, obesity and coronary disease.
A 2009 study published in the Journal of the American Society of Brewing Chemists, found that beer contains soluble fiber. So put away that fiber powder, bran and leafy greens and drink a beer! Lager contain about 2 grams of soluble fiber per liter, while darker beers contain up to 3.5 grams of soluble fiber per liter.
