Fruits rich in vitamin C (oranges, lemons, grapefruit, kiwi)
Fruits like oranges, lemons, grapefruits, tangerines and kiwis are known for their immune-boosting properties.
These fruits are rich in vitamin C, a powerful antioxidant that helps protect cells from damage caused by free radicals. It stimulates the production of white blood cells, an important part of the immune system that helps fight infection and disease.
In addition to vitamin C, oranges and tangerines also contain flavonoids (such as hesperidin and quercetin), which have anti-inflammatory effects and support blood vessel health, thereby helping the immune system function more effectively.
Yogurt
Yogurt is a great food to boost your immune system and prevent disease, thanks to its benefits. Probiotics found in yogurt are live bacteria that are beneficial to the intestines, helping to balance the microflora in the body.
About 70% of the human immune system is related to the gut. When the gut microbiota is healthy, the body can more easily fight off pathogens.
Probiotics like Lactobacillus and Bifidobacterium in yogurt improve nutrient absorption and reduce inflammation, thereby boosting the immune system.
Some yogurts are fortified with vitamin D, which helps regulate the immune system and increase resistance to infection. Vitamin D also helps reduce the risk of colds and flu.
Sweet potato
Sweet potatoes are a nutritious food that boosts immunity and prevents disease thanks to the Beta-carotene, a precursor of vitamin A, which plays an important role in strengthening the immune system. Vitamin A helps protect and regenerate tissues in the body, especially the respiratory and digestive mucosa - the first "barriers" against bacteria and viruses.
Beta-carotene is also an antioxidant, which helps reduce the risk of cell damage caused by free radicals.
Sweet potatoes contain a significant amount of vitamin C, which helps increase white blood cell production and improve the body's immunity. Vitamin C also promotes collagen production, which protects the skin - a natural barrier against pathogens.
