What are the effects of nutrition on the immune system during aging?
Best insight from top research papers
Nutrition plays a crucial role in the immune system during aging. Adequate intake of nutrients such as protein, vitamin D, n-3 fatty acids, antioxidant vitamins (vitamins C and E), zinc, selenium, and iron contributes to immune competence . Aging affects both the innate and adaptive arms of the immune system, leading to immunosenescence, which is characterized by defects in the formation, maturation, homeostasis, and migration of peripheral lymphocytes . Micronutrient deficiencies are common in the elderly and can further impair immune function, increasing susceptibility to infections . However, restoring deficient micronutrients to recommended levels through supplementation can improve immune function, enhance resistance to infection, and support faster recovery . Inadequate nutrition can also lead to decreased immune function, poor skin integrity, and loss of independence in older adults . Therefore, maintaining optimal nutrition is essential for supporting a healthy immune system during aging.

How does nutrition affect the health of people?5 answersNutrition has a significant impact on people's health. A poor diet, high in meat, fat, and processed foods, contributes to morbidity and mortality globally. On the other hand, predominantly plant-based diets have been shown to reduce the risk of chronic diseases such as cardiovascular disease, obesity, diabetes, and cancer. Nutrition plays a role in maintaining overall well-being and preventing diseases caused by inadequate and unbalanced nutrition. Good nutrition, including a balanced diet with fruits, vegetables, whole grains, dairy, and protein, is essential for a healthy life. Nutritional deficiencies can lead to disability, morbidity, and mortality, especially among infants and young children. Therefore, ensuring proper nutrition is crucial for promoting optimum health and preventing diseases.
The role of immune cell between periodontitis and aging?4 answersThe immune cell plays a crucial role in the relationship between periodontitis and aging. Periodontitis is associated with systemic inflammatory disorders, and its prevalence and severity increase with aging. Aging-related changes in innate and adaptive immunity contribute to the severity of periodontitis, including changes in neutrophil function and immune cell responses. Inflammaging, a chronic inflammatory state associated with old age, is linked to periodontitis and increased systemic inflammation markers. Immunosenescence, characterized by age-related alterations in the immune system, affects alveolar bone turnover and aggravates aging-related alveolar bone loss in periodontitis. The dysregulation between the periodontal microbial community and host immunity, along with immune senescence, increases the susceptibility to periodontitis, especially in the aging population. Understanding the role of immune cells in periodontitis and aging can provide insights for developing novel immunotherapies and treatment strategies.
What is the role of nutrition in the functioning of the immune system during aging?5 answersNutrition plays a crucial role in the functioning of the immune system during aging. Adequate nutrition is important for supporting the immune response and preventing immune impairments. Aging is associated with complex changes in the immune system, known as immunosenescence, which can increase susceptibility to infections. Poor nutrition, including low intakes of micronutrients, can further impair the immune system and increase the risk of severe outcomes from infections, such as COVID-19. Micronutrient deficiencies are common in the elderly and can negatively impact immune function. On the other hand, restoring deficient micronutrients to recommended levels through supplementation can improve immune function, enhance resistance to infections, and support faster recovery. Additionally, nutrition is important for promoting a diverse gut microbiota, which in turn supports the immune system. Overall, maintaining good nutrition is essential for maintaining a healthy immune system during aging.
How does vitamin C affect the immune system?5 answersVitamin C plays a crucial role in immune system regulation and the health of white blood cells (WBCs). It is involved in the expression of genes related to the immune system and can potentially enhance current therapies. However, the use of high-dose vitamin C as a prophylaxis for viral diseases, including COVID-19, is not supported by the literature. The effects of vitamin C supplementation may be more prominent in individuals with low baseline vitamin C levels, such as physically active persons or those with hypovitaminosis C. In elderly individuals, daily oral administration of vitamin C improves various immune functions, bringing them closer to those of young adults. Micronutrients, including vitamin C, are essential for the proper function of physical barriers and immune cells, and supplementation with multiple micronutrients, including vitamin C, vitamin D, and zinc, may modulate immune function and reduce the risk of infection.
How does immunosenescence affect the immune system?5 answersImmunosenescence, the gradual deterioration of the immune system due to aging, affects both innate and adaptive immunity. It is characterized by changes in antigen sensing, presentation, and cytokine responses of innate cells, as well as alterations in T and B cells throughout their life-cycle. Immunosenescence leads to impaired immune responses to infections, reduced response to vaccinations, and increased susceptibility to diseases. The aging immune system is also associated with a proinflammatory environment and the development of chronic diseases such as neurodegenerative and metabolic diseases. The mechanisms of immunosenescence can be influenced by an active lifestyle and adequate dietary measures.
