Which group of people is most at risk for riboflavin deficiency?

Individuals with chronic alcoholism are indeed the group most at risk for riboflavin deficiency. This is primarily because chronic alcohol consumption can lead to a variety of nutritional deficiencies due to poor dietary habits, impaired absorption of nutrients, and alterations in metabolism. Alcohol interferes with the body's ability to absorb essential vitamins and minerals, including riboflavin, which is crucial for energy metabolism and the maintenance of healthy skin, eyes, and nerve functions.

While athletes may have increased nutritional needs due to their activity levels, they typically consume higher amounts of calories and a more varied diet, thus reducing their risk for deficiencies when dietary intake is managed properly. Vegans may also be at risk for certain nutrient deficiencies; however, riboflavin is present in many plant foods such as green leafy vegetables, nuts, and fortified cereals, and therefore they can meet their needs with careful planning. Diabetics may face their own set of nutritional challenges and complications, but this does not directly correlate to a specific risk for riboflavin deficiency compared to chronic alcohol users.
