Immunity boosting nutrients

Immunity Boosting Nutrients

Healthy immunity is a prerequisite for fighting any viral or bacterial infection. One of the best ways to boost immunity is having foods rich in key nutrients. Recent research suggests that taking foods rich in certain vitamins and minerals may protect against respiratory tract infections.

Key Immunity-Boosting Nutrients

• Vitamin C: A powerful antioxidant that supports the production and function of white blood cells. Found in citrus fruits, amla, guava, bell peppers, and broccoli

• Vitamin D: Regulates immune response and reduces the risk of respiratory infections. Synthesised through sunlight exposure; also found in fatty fish, eggs, and fortified foods. Deficiency is extremely common in India

• Zinc: Essential for the development and function of immune cells. Found in legumes, seeds, nuts, whole grains, and meat

• Vitamin E: An antioxidant that helps fight off infection. Found in nuts, seeds, spinach, and vegetable oils

• Iron: Supports the immune system by helping carry oxygen to cells. Found in lentils, spinach, tofu, and lean meats

• Selenium: Plays a key role in inflammation regulation and immune response. Found in Brazil nuts, sunflower seeds, and whole grains

• Probiotics: Support gut health, which is closely linked to immune function. Found in yoghurt, buttermilk, idli, dosa, and fermented foods

• Omega-3 fatty acids: Reduce inflammation and support immune cell function. Found in flaxseeds, walnuts, and fatty fish

Lifestyle Habits That Support Immunity

• Get 7–8 hours of quality sleep every night

• Exercise regularly — moderate activity boosts immune surveillance

• Manage stress — chronic stress suppresses immune function

• Stay hydrated — water supports lymphatic circulation and toxin removal

• Avoid smoking and excess alcohol
