Boost Immunity: Eat Your Way to Flu Defense

As flu season intensifies across the United States, health experts highlight the crucial role of nutrition in strengthening the immune system. This season has already seen approximately 3 million cases and 30,000 hospitalizations, with a notable rise attributed to a new H3N2 variant.

Incorporating specific foods can significantly enhance immune function. Garlic, for instance, contains allicin, an antimicrobial and antiviral compound, along with vitamins B6 and C. Red bell peppers are packed with vitamin C, exceeding the daily requirement in a single serving. These nutrients act as antioxidants, aiding immune cells in fighting infections.

Furthermore, foods like yogurt, rich in probiotics, support gut health which is intrinsically linked to immunity. Berries offer a nutrient-dense, low-sugar option, with strawberries being an excellent source of vitamin C and blueberries containing immune-boosting flavonoids. Vitamin D, found in foods like salmon and mushrooms, is also vital for immune regulation.
