The high rate of malnutrition in the elderly suggests the need for increased availability of high nutrient density foods such as fruits, vegetables, milk, and whole grain products. An analysis of nutritional habits of 100 persons 75+ years showed that 75% had insufficient intake of whole grain products, 50% an insufficient intake of milk and dairy products, and 25% an insufficient intake of fruits and vegetables. Food intake was shown to be largely independent of such factors as sex, age, or life situation. Only for milk and dairy products could a better supply be shown for institutionalized persons than for independent-living persons. The results of the study emphasize the need for better nutritional information and education of the elderly regarding the importance of high nutrient density foods.
老年人中营养不良的高发生率表明，需要增加高营养密度食物的供应，如水果、蔬菜、牛奶和全谷物产品。一项对100名75岁及以上老人营养习惯的分析显示，75%的人全谷物产品摄入量不足，50%的人牛奶和奶制品摄入量不足，25%的人水果和蔬菜摄入量不足。食物摄入量在很大程度上与性别、年龄或生活状况等因素无关。只有牛奶和奶制品显示出，机构养老的人比独立生活的人供应更好。该研究结果强调，需要针对高营养密度食物的重要性，为老年人提供更好的营养信息和教育。
