VITAMINS AND MINERALS
a. Its’ importance in old age period:
The word “vitamin” means an “essential element for life”. Vitamins and minerals are existent in many organs of the body and they are necessary for the perpetuation of the body functions.Since many of them cannot be produced in the human body, intake of them by foods is necessary. As a result of inadequate vitamin and mineral intake, some deficiencies in the functions of particular organs appear dependent on the defects in metabolism. Due to the reduction in energy requirement in the old age period, the intake of the vitamins and minerals assigned in the energy metabolism decreases. Thus, the required amounts should be provided from the foods.
The impacts of vitamins and minerals in old age:
• Forming resistance to diseases by strengthening the immune system
• The protection of the bone and teeth health and the prevention of osteoporosis.
• The protection of skin health
• Blood formation
• The prevention of hypertension
• The protection from diabetes.
• Reducing the blood cholesterol which may create risk for cardiovascular diseases.
• Protection from cardiovascular diseases.
• Strengthening the brain functions and preventing problems like forgetfulness, dementia and depression
• Strengthening of muscles
b. Sources of vitamin and minerals:
Vitamins and minerals are existent in vegetables, fruits, cereals, meat, fish, milk and dairy products. While vitamin B12 is merely existent in animal products like meat and meat products,
milk and egg, other Group B vitamins are existent in both vegetative foods and animal foods. The best source of vitamin D is sunlight. Osteoporosis, a disease which occurs as a result of vitamin D
deficiency is widely existent in individuals whose contact with sunlight is rare. The vitamin, mineral and some nutrient group types whose deficiency may create problems in elderly are stated in.
c. The vitamin and mineral requirements in old age period:
The vitamin and mineral requirements increase due to the reasons like reduction in the energy requirement, decrease in the body resistance, limitation of mobility, frequency rates of chronic
diseases. Vitamin and mineral deficiencies may cause deaths by affecting the progress and deepening the impact of the acute and chronic diseases. In situations where there is no health problem or limitation of food intake concerning the usage of vitamins and minerals,the requirements of vitamins and minerals with the exception of vitamin D, may be provided from the foods with a well-planned diet.
Since intake of excessive amounts of some vitamins and minerals like supplements may cause poisoning, vitamin and mineral (nutrients like tablets, syrups which are taken as supplements for
diet) should be taken by the recommendation of a dietician or doctor. This requirement should be satisfied by natural sources or foods unless compulsory usage of the diet supplements. In some studies, a positive effect or side-effect of vitamin supplements like vitamin-A (beta carotene) or vitamin E which are retardant with respect to frequency rates of cancers and cardiovascular diseases or deaths was not observed. Therefore, the providing of vitamins and minerals (with the exception of vitamin D) through a diet is more beneficial with respect to their
functions.
