Rationale: Senior citizens need more of vitamins and minerals to remain healthy and active
Individuals of 60 years and above (WHO) constitute the elderly. In India, the elderly constitute about 7 percent of the total population (Census, 2001) and by 2016 and by they are likely to increase to 10 percent.
Ageing affects almost all the systems of the body, and is associated with several physiological, metabolic and psychological changes. The changes include decline in physical activity, digestion, metabolism, bone mass and muscle mass. Failing eye-sight and impaired hearing may also occur. Low appetite as a result of loss of taste and smell perception, dental problems, atrophic changes in GIT, constipation and decreased physical activity could lead to overall decrease of food intake and poor absorption of nutrients. Inability to prepare food, economic dependency and other psycho-social problems adversely affects the health and nutritional status of the elderly.
There is a decline in immune function with advancing age, which leads to decreased resistance to infectious diseases. The increased parathyroid hormone (PTH) secretion in the elderly leads to increased bone turn over i.e. osteoporosis. Similarly, elderly individuals are at increased risk of osteomalacia i.e. defective bone mineralization due to lack of exposure to sunlight and poor diet.
In general, majority of the health problems among the elderly are nutrition related. Consumption of nutritious foods rich in micronutrients including antioxidant vitamins & minerals and fibre, comfortable level of physical activity would enable the elderly to live active and meaningful healthy lives, without being a burden on society and their family members. Uncomplicated ageing can also be quite productive, say in the domestic sphere.
Resistance to disease declines in the elderly. The common ailments in the elderly are degenerative diseases such as arthritis (joint diseases), osteoporosis, osteomalacia, cataract, diabetes, cardiovascular (stroke, heart diseases) problems, neurological (Parkinson's, Alzheimer's) and psychiatric (dementia, depression, delirium) disorders and cancer. Besides these, the prevalence of respiratory, gastro intestinal tract (GIT) and urinary tract infections is common among the elderly.
As people grow older, they tend to become physiologically less active and therefore need fewer calories to maintain their weights. The daily intake of oil should not exceed 20 g. Use of ghee, butter, vanaspati and coconut oil should be avoided. They need foods rich in protein such as pulses, toned milk, egg-white etc. The elderly population is prone to various nutritional deficiencies. Therefore, the elderly need nutrient-rich foods rich in calcium, micro-nutrients and fibre. Apart from cereals and pulses, they need daily at least 200-300 ml of milk and milk products and 400 g of vegetables and fruits to provide fibre, micro-nutrients and antioxidants. Inclusion of these items in the diet improves the quality of the diet and bowel function.
The diet needs to be well cooked, soft and less salty and spicy. Small quantities of food should be consumed at more frequent intervals and adequate water should be consumed to avoid dehydration, hyponatraemia and constipation.
Exercise is an integral part of maintaining healthy life. It helps to regulate body weight. The risk of degenerative diseases is considerably decreased by regular exercise. Exercise schedule should be decided in consultation with a physician.
