Vitamin C deficiency: A reemerging problem?

Recent data from national surveys as well as clinical investigations indicate that the prevalence of vitamin C deficiency may be increasing. This trend is likely a reflection of poor dietary habits. High risk populations include those with limited access to fresh fruits and vegetables, elderly persons living in urban areas, particularly men who live alone and prepare their own food, smokers, alcoholics and fad dieters. Physicians should examine patients for signs and symptoms of subclinical scurvy. Assessment of fruit and vegetable consumption should be included in standard medical examinations and patient counseling sessions. The inclusion of vitamin C-rich fruits and vegetables in the diet on a daily basis is an important, but under-emphasized, component of nutritional health.
