Beer is made from hops, barley and wheat, so the beverage contains many of the same nutrients that grains do, including B vitamins, riboflavin, niacin and zinc. A bottle of beer can contain 92 mg of potassium, 14 mg of calcium and 48 mg of phosphorus, all minerals that are essential to a healthy diet.
Beer is also a source of soluble fiber, which comes from the barley. According to The Brewers of Europe, an organization that represents European breweries, two glasses of beer can provide 10 percent of your recommended daily fiber intake.
Beer contains antioxidants as well. A study published in the Journal of Nutrition and Biochemistry suggests that the levels of antioxidants found in blood are elevated after beer is consumed.
