Boost Your Immunity Through Food
Strengthen your natural defenses through food. The best foods to boost your immune system.

The link between food and immunity
70% of our immune system is in the gut. What we eat directly influences our ability to fight infections.
Key nutrients for immunity
Some nutrients play a central role in immune function:
- Vitamin C: citrus, kiwi, peppers, broccoli
- Vitamin D: mushrooms, sun exposure, supplementation
- Zinc: pumpkin seeds, cashews, legumes
- Probiotics: kombucha, yogurt, fermented foods
- Vitamin A: carrots, sweet potatoes, spinach
- Selenium: Brazil nuts, sunflower seeds
Foods to prioritize in winter
In winter in Geneva, focus on citrus, ginger, turmeric, garlic, broths and fermented foods. Avoid refined sugar which temporarily weakens the immune system.
