Tips for Taking Care of Your Body During Puberty

It’s important for teenagers to take care of their bodies during puberty. Here are some tips:

Eat a healthy diet

A healthy diet is important during puberty to provide the body with the nutrients it needs for growth and development. Teenagers should eat a variety of fruits, vegetables, whole grains, and lean protein sources.
