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.
Good Sources of Protein. The daily intake of protein can be up to 15% of the total nutrients we eat. One way to work out how much protein you need for a day is multiply your weight with 0.75 protein per day. So if you weight about 51kg, you need about 38g of protein a day.
