Low-fat milk alternative made from oats Whether you’re looking for a dairy-free take on skim milk or are just trying to decrease your fat intake overall, this low-fat oat milk should do the trick. It only has 1 gram of fat that comes straight from the oats it's made with. That’s as low-fat as you’ll get before being totally fat-free. And what it lacks in fat, it makes up for in vitamins A,D, and B12 and minerals like calcium and iron. Pour it over cereal, put it in your coffee, or down it straight from the carton. It’s up to you.
