Citrus and Guava Spotlighted for Immune-Boosting Benefits

Citrus fruits such as oranges, mandarins, lemons and grapefruits are highlighted for their vitamin C content, fiber, minerals and antioxidant compounds like flavonoids and carotenoids. Their pulp, peel and essential oils also find applications in food flavoring, perfumery, cosmetics and certain industrial processes, underscoring their broad nutritional and commercial value.

Guava is presented as an even richer source of vitamin C, together with provitamin A and high dietary fiber that supports gut microbiota. Nutrition experts advise eating the fruit whole rather than as juice, avoiding direct heat to preserve nutrients, and pairing it with healthy fats to enhance absorption. These recommendations aim to maximize the fruit’s immune‑supporting properties.
