Getting enough vitamins and minerals will support your immune system to help fight off colds, flu and other illnesses. The best way to get enough immune-boosting nutrients is to eat a wide variety of vegetables. Eating an assortment of nutrient-dense foods will provide the biggest immune boost because no single nutrient can cure or prevent illness.
Mix of Minerals-
According to Harvard Medical School, minerals such as zinc, copper, iron and selenium have the greatest effect on immune function. Zinc can be found in oysters, beef and crab. Copper and iron work together in the body to support the immune system. They can be found in oysters and other shellfish, beans, potatoes and organ meats. Satisfy your selenium needs with Brazil nuts, tuna and halibut. Consume mineral-rich red meat in moderation. Limit your intake to one or two servings per week to avoid excessive cholesterol intake.
Vitamins for Vitality-
The best vitamins for immunity are vitamins A, E, C and the B complex vitamins, reports the Academy of Nutrition and Dietetics. Vitamins C and E act as antioxidants that help protect cells from harmful free radicals. Scientists at the University of Copenhagen discovered that vitamin D plays a significant role in the activation of the immune system as well. A deficiency of any of these vitamins may led to decreased immunity and greater risk of disease. Remember that most nutrients work together, so being deficient in one or more nutrients may lead to a deficiency or malabsorption in another.
Food Sources –
Consuming a wide variety of nutrient-dense food is more effective than consuming a variety of supplements. To get enough vitamin C, choose citrus fruits, cantaloupe, broccoli and red peppers. For adequate vitamin E intake, try snacking on nuts and cooking with vegetable oils such as olive oil. You can find vitamin B-6 in tuna, turkey and bananas. If you take any medications that may affect nutrient absorption, however, or if you have a serious health condition, you should consult your health care provider or dietitian to ensure proper nutrient intake.
