The Nutritional Immunology Laboratory investigates the role of dietary components and their interactions with other environmental factors and genes in age-associated changes of the immune and inflammatory responses. Our research looks to reverse and/or delay the onset of these immunologic and age-related changes by appropriate dietary modifications and to determine the molecular mechanisms by which nutrients modulate immune cell functions.

BOSTON (Feb. 8, 2017)—In a clinical trial, adults who consumed a diet rich in whole grains rather than refined grains had modest improvements in healthy gut microbiota and certain immune responses. The research was conducted in tandem with a study that looked at the effects of a whole-grain diet on energy metabolism. Both studies are published online today in the American Journal of Clinical Nutrition.

Baby boomers will face many barriers to good nutrition as they age. It’s time to get prepared.
Eating right as an older adult takes a bit more effort. Even if you stay the same weight as you age, you have less lean muscle mass and your metabolism slows down, which means you need fewer calories than you once did. At the same time, your nutrient needs stay the same or even increase. Your body may have trouble absorbing certain nutrients, such as B12 and magnesium.
That’s why making every bite count is even more important for seniors.
