Citrus fruits like oranges, lemons, and grapefruits are well-known for their high vitamin C content, a nutrient essential for a robust immune system.

Incorporating citrus fruits into your diet can be as simple as enjoying a fresh fruit salad, a glass of orange juice, or a squeeze of lemon in your water, offering a refreshing and immune-boosting treat.
