Want to be healthy? Eat more lemons. Lemon contains a high amount of Vitamin C, a natural antioxidant that improves the immune system. One lemon can offer about half of your recommended daily value of Vitamin C.

Lemon has antibacterial and antiviral qualities. It helps strengthen the immune system against germs that cause the common cold and the flu. A common folk remedy for cough and cold is to take a glass of warm lemon juice with honey.

An easy way to take lemon daily is to add its juice to your meals. Squeeze lemon juice into your salad. Or add a few drops of lemon to your roasted veggies or chicken. You can also use the juice of a lemon to marinate your meat.
