With the rise in life expectancy, there has been an increase in the population with immune deficiency. This necessitates the need to find ways to improve the quality of life and survival rate for these individuals. This review focuses on dietary modifications as a means to boost the immune system.
The abstract emphasizes the significance of nutrition and lifestyle changes in supporting immune function. A well-balanced diet, rich in essential nutrients and immune-boosting foods, is crucial. Addressing nutrient deficiencies, engaging in regular physical activity, and managing stress are also important for improving immune health. Individuals with immune deficiencies should seek guidance from healthcare professionals when making dietary changes.
Food safety is closely linked to immune health, especially for immunocompromised individuals who have a higher risk of foodborne diseases. Preventing foodborne infections involves implementing food safety management systems and following low microbial diets.
While diet is significant, other interventions are also important for individuals with compromised immune systems. Planning a healthy diet for these patients should consider adequacy, balance, calorie control, nutrient density, moderation, and variety.
In conclusion, enhancing the immune system and improving the quality of life for individuals with immune deficiencies requires a comprehensive approach that includes dietary modifications, food safety practices, and other lifestyle changes. By implementing these strategies, it is possible to strengthen the immune system and enhance health outcomes for individuals with compromised immune function.
