Recent studies from our laboratory demonstrate that a nutritional supplement with elevated levels of antioxidants (vitamins E, C, and β-carotene), selenium, zinc, fructo-oligosaccharides (FOS), and structured lipids can reduce cold and flu symptoms and improve responses to the influenza vaccine in older adults. Unfortunately, the design of these studies does not allow one to identify which nutrient or nutrients are responsible for the immune benefit. On-going studies in our laboratory examine the individual effect of these nutrients on mucosal immunity.
