Boost your immune system by managing stress; getting plenty of sleep; practicing good hygiene; and — you guessed it — eating a well-balanced diet with protein, carbohydrates, fats, and lots of fruits and vegetables.
No single nutrient can protect you from illness, but regularly eating a variety of nutrients boosts your immune system. Look for these immune-supportive nutrients and foods that contain them:
- Vitamin C: Citrus fruits (like oranges and grapefruit), red and green bell peppers, kiwifruit, broccoli, strawberries, potatoes, and tomatoes
- Vitamin D: Rainbow trout, salmon, mushrooms, fortified milk, sardines, fortified breakfast cereals, and eggs
- Beta-carotene: Carrots, sweet potatoes, dark leafy greens, squash, cantaloupe, and red and yellow peppers
- Zinc: Oysters, beef, crab, lobster, pork, beans, and fortified breakfast cereals
- Protein: Meats, seafood, eggs, beans, and peas
- Probiotics: Yogurt, sauerkraut, tempeh, and kimchi
