Asteroids range in size from Ceres-the largest at about 950 kilometers (590 miles) in diameter and also identified as a dwarf planet-to bodies that are less than 1 kilometer (0.6 mile) across. The total mass of all the asteroids combined is less than that of Earth's Moon.
While much of the protein in the American diet comes from beef and pork, this isn't necessarily the case around the world. People in some countries eat little or no meat, getting much of their protein from vegetarian protein sources, and some people get their protein from foods many Americans have never tried.
Low-fat dairy products also qualify as sources of lean protein. Quinoa is a low-fat grain thatâs a complete protein. Beans and legumes are naturally low-fat sources of protein. Depending on the type of bean, 1 cup may have 12 to 20 grams of protein and .5 to 1.5 grams of fat.
