Would you like to boost your immune system naturally?
A strong immune system is the key to better health and well-being – especially during the colder months. A balanced diet with the right nutrients can support your body’s defenses and make you more resilient to colds and other infections. Here’s a guide to the foods and vitamins that matter most and how to easily include them in your daily life.
Fresh foods as the foundation of a strong immune system
Nature provides everything our bodies need. Fresh, seasonal and locally sourced foods are especially rich in vitamins, minerals and other valuable nutrients.
Food / sources | Benefit for a strong immune system |
Berries, citrus fruits, broccoli, bell peppers | Rich in Vitamin C, which strengthens immune cells and protects against oxidative stress. |
Nuts, seeds, whole grains, dark leafy greens | Rich in magnesium, which plays a key role in activating Vitamin D and supports immune cell function. |
Fatty fish (salmon, mackerel), eggs, fortified products | Provide Vitamin D, which strengthens immune responses and regulates inflammation, especially in winter months. |
Dark leafy greens, carrots, sweet potatoes | Contain beta-carotene (a precursor to Vitamin A), which supports mucous membranes and acts as a barrier against pathogens. |
Whole grains, legumes, nuts, oysters, pumpkin seeds | Rich in zinc, which activates immune cells, protects mucous membranes and reduces oxidative stress. |
Garlic, turmeric, thyme, elderberry | Contain anti-inflammatory compounds that reduce inflammation and support overall immune health. |
Chicory, artichokes, black salsify | Provide prebiotic fiber, which nourishes beneficial gut bacteria and supports a healthy gut microbiome essential for immunity. |
Plant-based foods (general) | Rich in fiber, which supports gut health, where a significant portion of the immune system resides. |
Sunflower seeds, pork, whole grains | Rich in Vitamin B1 (Thiamine), which supports energy metabolism and is essential for immune cell activity. |
Eggs, dairy products, mushrooms, almonds | Contain Vitamin B2 (Riboflavin), which helps maintain healthy mucous membranes and protects cells from oxidative stress. |
Poultry, turkey, peanuts, tuna | Provide Vitamin B3 (Niacin), which contributes to energy metabolism and supports immune defenses. |
Avocados, mushrooms, sweet potatoes | Contain Vitamin B5 (Pantothenic Acid), which promotes the production of immune-supporting hormones and boosts energy. |
Bananas, chickpeas, poultry | Rich in Vitamin B6, which is essential for antibody production and immune cell communication. |
Eggs, almonds, sweet potatoes | Provide Vitamin B7 (Biotin), which supports cell growth and helps maintain mucous membranes. |
Leafy greens, lentils, beans | Contain Vitamin B9 (Folate), which plays a role in cell division and supports the production of new immune cells. |
Fish, meat, dairy products | Rich in Vitamin B12, which supports red blood cell formation and DNA synthesis in immune cells. |
Brazil nuts, eggs, fish | Provide selenium, which boosts immune cell activity and combats oxidative stress. |
Nuts, seeds, shellfish | Contain copper, which increases the lifespan of white blood cells and enhances immune defense. |
Red meat, spinach, lentils | Rich in iron, which supports normal immune function and improves oxygen transport in the body. |
