The main objectives of our proposed study are to determine the effects of mango consumption on immune and cognitive functions in free-living college going young adults aged 18-30. To accomplish these objectives, a randomized controlled, parallel design study is proposed with two groups consuming their habitual diet, but with one (Mango group) receiving 1.5 servings of mango/day and the other (Control group) abstaining from eating any mango for the duration of the study.
