Nutrition and immunity: perspectives on key issues and next steps

Area of Science:

• Nutritional Immunology
• Dietary Science
• Immunology

Background:

• Experts convened in January 2022 for a Canadian Nutrition Society symposium on nutritional immunology.
• The symposium addressed the complex diet-immune system interactions from infancy to old age.

Purpose of the Study:

• To summarize key perspectives and future research directions in nutritional immunology.
• To highlight the role of micronutrients and dietary patterns in immune health.
• To discuss dietary recommendations for improving immune function and managing immune-related conditions.

Main Methods:

• Expert symposium discussions.
• Review of current research on diet, inflammation, autoimmune conditions, allergies, and infections.
• Identification of knowledge gaps in nutrition and immune function research.

Main Results:

• Understanding the interplay between diet and immune function across the lifespan.
• Emphasis on the critical role of specific micronutrients in immune system vitality.
• Exploration of dietary patterns and novel approaches for managing inflammation and immune disorders.

Conclusions:

• Further research is needed to fully elucidate the dynamic relationship between nutrition and immune function.
• Dietary strategies hold significant potential for modulating immune responses and preventing disease.
• Personalized nutrition approaches may be key to optimizing immune health across different life stages.
