Factors Affecting Immunity in Aging
- How and why do you think Nutritional factors, psychological factors, drugs and complementary and alternative medications affect the immune system in older adults.
Impact of Nutritional, Psychological, Drug, and Complementary Factors on the Immune System in Older Adults
The immune system naturally weakens with age, a phenomenon called immunosenescence, which makes older adults more susceptible to infections, chronic diseases, and complications. Various factors, including nutrition, psychological health, medications, and complementary and alternative therapies, can influence immune function in older adults. Understanding how these factors interact is crucial for maintaining a healthy immune system in this population.
1. Nutritional Factors
How They Affect the Immune System:
- Protein and Micronutrient Deficiency: Adequate protein intake and essential micronutrients (e.g., vitamins A, C, D, and zinc) are critical for immune cell production and function. Malnutrition or deficiencies in these nutrients can impair immune responses and increase susceptibility to infections.
- Antioxidants: Antioxidants, found in fruits and vegetables, help combat oxidative stress, which can damage immune cells and contribute to aging. A diet low in antioxidants can accelerate immune system decline.
- Omega-3 Fatty Acids: Omega-3s, found in fatty fish and some plant oils, help regulate inflammation. Chronic inflammation is common in aging and can suppress immune function…
