Health maintenance issues of the elderly. Nutrition

Although we are on steep learning curve as far as the exact relationship between nutrition and disease prevention is concerned, evidence is accumulating on the role of body mass index and mortality, protein deficiency and decreased ability to fight infection, effect of fiber intake on cholesterol and glucose metabolism, hyperlipidemia and atherosclerosis, and inadequate calcium intake in osteoporosis. Screening for nutritional disorders includes identifying those with risk factors of being female, black, poor, or institutionalized. Evidence of weight change, dietary idiosyncracies, nutrient deficiency, and laboratory tests can be helpful. Treatment should be tailored to the individual and be specific for suspected deficiencies. Attention to calories, protein, and calcium are paramount.
