Enzymes—and Proteins—at Work

What are some other problems associated with an insufficient intake of protein?

For most people—adults and children—an inadequate intake of protein can lead to several body-oriented problems. For example, because hair is made up primarily of protein molecules, a lack of protein in the diet will essentially cut off the supply, causing hairs to fall out or even slow down growth in order to conserve protein. Another problem with low protein intake is a decrease in lean body mass and compromised muscles and muscular strength. For example, with less protein consumed, it will take much longer for a person’s muscles to recover after strength-training exercises.
