What are the effects of nutrition on immune system health?.

Nutrition significantly influences immune system health. Adequate intake of vitamins, minerals, and antioxidants helps maintain immune function, while nutrient deficiencies can impair the body's ability to fight infections. Key nutrients include:

• Vitamin C: Boosts the production of white blood cells, essential for fighting infections.
• Vitamin D: Enhances pathogen-fighting effects of monocytes and macrophages.
• Zinc: Crucial for the development and function of immune cells.
• Probiotics: Support gut health, which is linked to immune function.

Key Facts

• Vitamin C: A study showed that it can reduce the duration of colds by 8% in adults and 14% in children.
• Vitamin D: Insufficient levels are associated with increased risk of respiratory infections.
• Zinc: Deficiency can lead to a 25% increase in susceptibility to infections.
• Probiotics: Regular intake can reduce the risk of respiratory infections by 27% according to some studies.
