Spinach

Spinach is an excellent food to add to your diet. This leafy green vegetable is available all year and is high in vitamins and minerals. 943 micrograms of vitamin A are found in one cup of boiling spinach (105% DV for men, 135% DV for women). Your body uses the vitamin A in spinach to build tissues, including your skin, which is the largest organ in your body. Vitamin A not only improves the skin's immune system (by preventing sickness and damage), but it also keeps it moisturized, which reduces the appearance of fine lines and wrinkles.

This leafy green also contains 6.43 mg of iron per cup (35.7% DV). Iron is required for the production of hemoglobin, a protein found in red blood cells that delivers oxygen throughout the body, and myoglobin, a protein that gives oxygen to muscles. Spinach is high in potassium and other nutrients that your body requires. Potassium-rich foods can help you maintain a healthy blood pressure level. Spinach is high in lutein, an antioxidant that helps to prevent age-related eye problems including macular degeneration and cataracts. People who take lutein supplements have a lower risk of macular degeneration, which is the major cause of vision impairment and blindness, according to studies.
