Banana
Bananas are rich in vitamin B6, which plays an important role in the production of immune signaling molecules. A study published in the International Journal of Macromolecular Biology found that lectins in bananas help boost immunity.
Bananas' prebiotic fiber supports gut bacteria, which is essential for immunity. Eating a medium-sized banana a day ensures sustained energy and immune support.
Strawberry
Strawberries are rich in vitamin C, anthocyanins and antioxidants that help stimulate the immune system. A study published in the journal Nutrients found that regular consumption of strawberries can help reduce inflammation in the body.
Papaya
Papaya contains papain, a digestive enzyme that helps reduce inflammation, along with beta-carotene and vitamin C, which help boost immune response. Papaya's vitamin A content is also important for maintaining the health of the respiratory mucosa, which helps boost immunity.
Pineapple
Pineapple is a rich source of bromelain, an enzyme with anti-inflammatory and antibacterial properties. Eating pineapple in winter helps boost immunity. A study published in the journal Nutrition and Metabolism also stated that pineapple reduces stress related to the heart. Eating 1-2 slices of fresh pineapple or drinking fresh pineapple juice daily helps support immunity and digestion.
Kiwi
Kiwis are rich in vitamin C, vitamin E and polyphenols, making them one of the essential fruits for boosting immunity. A study published in the Journal of Food and Agricultural Immunology found that eating kiwis improves the activity of T cells and natural killer (NK) cells, which are important for fighting infections. One kiwi provides more than 80% of the recommended daily intake of vitamin C.
