Does your diet affect your immune system?

ANSWER

What you eat affects your immune system.

While no single food will upgrade your immune system, poor nutrition can have a negative effect on the immune system. What counts is having a balanced diet.

Fruits and vegetables are rich in vitamins and minerals that are good for you. If you're thinking about getting supplements to cover your nutritional needs, check with your doctor or a dietitian.
