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.
Proteins. Proteins are often called the bodyâs building blocks. They are used to build and repair tissues. They help you fight infection. Your body uses extra protein for energy. Good sources of protein are seafood, lean meat and poultry, eggs, beans and peas, soy products, and unsalted nuts and seeds. Protein is also found in dairy products.
