Cosmetics & Toiletries: Can nutrition affect beauty? If so, how?
If the body doesn’t have an adequate source of amino acids, it can’t make protein. Proteins are also the building blocks for the brain, nerves, muscle, etc.; and of course, a healthy inside leads to a healthy outside.
The most common problem I see in people with brittle nails or who are starting to lose hair is that they’ve decided to go on a strict vegan diet and don’t know enough to balance vegetable proteins so they get complete nutrition. It’s important to ensure you eat everything you need for your body to be beautiful.
Another issue with nutrition is if you eat a lot of foods that have what are called advanced glycation end products, or AGEs. When your body absorbs them, they can cause trouble. You get them from eating too much sugar because sugar glycates or alters the proteins in the body. You can also get them from high-temperature heated foods. So, it’s a balance of getting enough of the right foods and minimizing the wrong foods.
