You need it in your life
Why is dairy important?
Dairy has a lot of calcium. Calcium is important to have in your diet because it makes your bones strong. At the age of 30 you begin to lose bone mass so that's why it's important to get as much calcium as possible now.
Osteoporosis is a disease which causes weak bones that can easily break. To avoid this disease you should build healthy bones while you're young, maintain a healthy diet, and a healthy lifestyle.
