Proteins are the building blocks for our hair, skin, and nails. Keratin and collagen are two important proteins that you have likely heard of before. While collagen supplements are a hot trend these days, they are quite expensive and the science is not particularly strong that they actually reduce wrinkles. Instead, eat a variety of protein sources in order to get a good mix of amino acids. By choosing whole proteins (instead of supplement powders) you will also get other nutrients that are important for good health.
Take Action: Nuts, beans, soy, eggs, Greek yogurt, tuna, and turkey are excellent (and tasty!) protein choices. Be sure to include a protein-rich food at every meal and snack.
