Well Balanced Diet Important For Your Immune System

May 20, 2020

When you eat better, you feel better

“A minimum of six servings of fruits and vegetables daily is recommended to get adequate vitamins, minerals, fiber and antioxidants – all things we need for a healthy immune system,” says Ronda Elsenbrook, a registered dietitian in Nutritional Services at Kelsey-Seybold Clinic. “Adding more fruit and vegetables of any kind to your diet can help improve your general health.”

Some foods are higher in antioxidants than others. The three major antioxidant vitamins are beta-carotene, vitamin C and vitamin E.

“You’ll find them in colorful fruits and vegetables – especially those with purple, blue, red, orange, and yellow hues,” notes Ronda. To get the biggest benefits of antioxidants, consider eating these foods raw or lightly steamed.”

The following are some foods that can help you maintain a well-balanced diet:

  • Beta-carotenes and other carotenoids such as apricots, asparagus, beets, broccoli, cantaloupe, carrots, corn, green peppers, kale, mangoes, turnip and collard greens, nectarines, peaches, pink grapefruit, pumpkin, squash, spinach, sweet potato, tangerines, tomatoes, and watermelon.
  • Foods rich in vitamin C such as berries, broccoli, Brussels sprouts, cantaloupe, cauliflower, grapefruit, honeydew, kale, kiwi, mangoes, nectarines, orange, papaya, red, green or yellow peppers, snow peas, sweet potato, strawberries, and tomatoes.
  • Vitamin E foods like fortified cereals, nuts and oils, peanut butter, turnip greens, tomato sauce and paste, wheat germ, avocado, spinach, dandelion greens, sardines and broccoli.
  • Other super foods heavy in antioxidants including prunes, apples, raisins, all berries, plums, red grapes, alfalfa sprouts, onions, eggplant and beans.

“By getting the adequate nutrients to your immune system, you improve your body’s ability to fight illness,” Ronda says. “ Therefore, one of the defenses against viral infections is to eat the recommended six to eight fruits and vegetables to help support a healthy immune system.”
