As we age, our immune system weakens, making us more vulnerable to infections and illnesses. The nutrients we extract from food play a key role in maintaining a strong immune response, so a nutrient-dense diet is essential for overall health. Antioxidant-rich foods, in particular, help neutralize harmful free radicals that can damage cells, while sugary foods trigger inflammation, which can suppress the immune system. To strengthen immunity, incorporate foods like blueberries, strawberries, goji berries, red cabbage, beans, dark chocolate, pecans, spinach, carrots, and potatoes—all rich in powerful antioxidants that support your body’s defense mechanisms.
