Upon close examination by nutritional professionals, concern has arisen regarding the typical contents of a young adult diet. In terms of the rate at which young adults choose to consume nutritionally-dense food items, the rate at which nutrition-deficient junk food items are chosen over the former is significantly higher. Among further examinations of this issue by researchers, it has become evident that the nutritional decisions made by young adults are increasingly associated with several social, commercial, mental, educational, and economic influences. As a consequence of these factors, research has uncovered a connection between the consumption of a poor diet and negative effects on the physical and mental health of young adults. The goal of this research is to review the literature composed on the connection between nutrition and young adult health, examine the solutions postulated for the improvement of young adult nutrition, and propose the positive mental and physical health outcomes for young adults that may result if the aforementioned solutions are used.
