Rapid progression in the field of medical science has certainly increased the life expectancy of human beings. The bar of average lifespan has certainly risen. As a consequence, every nation today is showing an increase in the elderly population. Nutrition forms a very potent issue with regard to the health of this part of the population.

With age, the metabolism of the body slides down calling for major changes in one’s diet plan. For this very reason, the intake of calories must be reduced. However, the catch is that despite the reduction in calories, the elderly must consume a nutrient rich diet to stay away from fatigue, depression and other ailments. In this respect, ‘nutrient dense’ foods are the best alternative such as low-fat milk. Consumption of protein should also be considerably lessened as the aging kidneys are unable to process the proteins in the diet. Consumption of complex carbohydrates is a good option for the elderly. Fiber is also a must as it aids in adequate bowel functioning. Fiber can be obtained from vegetables, fruits, grain products, cereals, seeds, legumes and nuts.

Even at an older age, the nutrient that the human body requires in the same quantity is protein. While the body has the capacity to store fat-soluble vitamins, vitamin D may be lacking due to lesser outdoor activities in this age. This deficiency can be overcome by consuming Vitamin D fortified milk. Vitamin E rich food such as whole grains, peanuts, nuts, vegetable oil, and seeds is known to decrease the incidence of the Alzheimer’s disease in seniors. Deficiency of Vitamin B12 is associated with hearing and memory loss, therefore the elderly should eat eggs and dairy foods regularly to maintain this nutrient’s level in the body. Muscular deterioration can be prolonged in the elderly by the intake of Vitamin C, Vitamin E, zinc, lutein, zeaxanthin and beta carotene, which can be obtained by eating a minimum of 5 helpings of dark green, orange and yellow fruits and vegetables. Five to eight glasses of water are essential to avoid constipation and improvise the functioning of the kidney.
