Eat meat -- and other protein sources.
Protein maintains muscles, and manufactures cells, enzymes, and hormones. It also helps produce the extra blood you need for your baby to develop normally. Poultry, fish, lean meats, low-fat dairy products, and some combinations of grains and legumes, such as rice and chickpeas or black beans, are packed with protein. Eggs and nuts are good sources, too. Aim to include at least three servings of poultry, fish, meat, or legumes, and three or four servings of low-fat or nonfat milk, yogurt, or cheese in your diet every day.
