Study Finds Plant-Based Foods Lower Inflammation, Boost Immunity

Chronic inflammation, a risk factor for diseases like heart disease, cancer, and diabetes, can be influenced by diet, stress, and other lifestyle factors. Recent research from the UK Biobank found that both the source of protein (animal vs. plant) and fiber intake are related to inflammation levels in older adults, with plant-based proteins and higher fiber generally being favorable. Experts emphasize that certain foods—such as extra virgin olive oil, which is rich in anti-inflammatory polyphenols, and fermented foods like kimchi—can help reduce inflammation and support immune health. Additionally, nutrient deficiencies in vitamin D, zinc, selenium, and omega-3s, as well as poor gut health, have been highlighted as key factors that can undermine immune resilience against infections and future pandemics. Supplements may be necessary to address some of these nutrient gaps, but a diet rich in fruits, vegetables, whole grains, and healthy fats is recommended for optimal immune and inflammatory regulation. Overall, dietary choices play a significant role in managing inflammation and supporting immune function.
