Nutrition and aging--practical advice for healthy eating.

Abstract

This article provides practical advice about foods and dietary supplements that are beneficial for the health of older people. Overweight and obesity are among the most common nutrition-related disorders in older people. A plant-based diet is associated with reduced risk of chronic diseases such as obesity, cardiovascular disease, cancer, and diabetes. Vitamin B12 deficiency is prevalent in older adults, but there are misconceptions about the causes, consequences, and treatments. Diminished synthesis of vitamin D in the skin that occurs with aging and poor dietary intake contribute to the high prevalence of poor vitamin D status in older adults. Vitamin D deficiency is associated with chronic disorders beyond poor bone health. Supplements containing vitamin B12 and vitamin D will help older adults meet their needs for these key nutrients.
