How do old women supply nutrition
Summary:According to the change of the physiological function of every systematic organ of the elderly's organism, the elderly's nutrition should defend always preventing disease emphatically, seek to keep physically and mentally healthy and prolong life. (1)Heat energy: The elderly's heat requirement increases and reduces with age. When generally taking as 9623- 10878 kJs for every day at 20- 34 years old, the requirement of person 70- 90 years old is 7531- 8360 kJs, this is because the basic metabolism rate of the elderly is reduced and reduced reason of manual labor.
According to the change of the physiological function of every systematic organ of the elderly's organism, the elderly's nutrition should defend always preventing disease emphatically, seek to keep physically and mentally healthy and prolong life. So the requirements for various nutrient and between twenty and fifty and different to some extent.
(1)Heat energy: The elderly's heat requirement increases and reduces with age. When generally taking as 9623- 10878 kJs for every day at 20- 34 years old, the requirement of person 70- 90 years old is 7531- 8360 kJs, this is because the basic metabolism rate of the elderly is reduced and reduced reason of manual labor. So the nutritionist's suggestion is in 50- 90 years old ranges, energy supplies the constant adult to reduce by 10%, 60- 20% for 90 years old, and reduce by 30% 70 years old later. But the reduction of heat is often accompanied by the reduction of the total amount of food in fact. The requirement for other nutrient might not be reduced with increase of age, so should arouse attention.
(2)Protein: The need of the elderly protein is not lower than adults, formate the supersession and slow down gradually because of increase of the catabolism, it is apter to happen that it is balanced to be defeated by nitrogen. So, the elderly's protein supply is not lower than adults, especially like this while calculating according to one kilogram of weight. Select more high-quality proteins in order to make better use. In general cases, protein should be raised too in taking the proportion of total amount of day, about 12%-14%.
(3)Carbohydrate: The elderly should use different types of carbohydrate, but the proportion of many candies should not be too small, it is a bit smaller that fructose changes into the possibility of the fat in the body, so the jam and honey can be eaten as a part of candy. In normal cases, the proportion that the carbohydrate occupies in the total amount of heat is suitable about 60%.
(4)Fat: The elderly need fat like adult, it contributes to the absorption of lipid-soluble vitamin, improve the flavor of the vegetables food. The fat should take vegetable oil as the core, but is uncertain that cancels all animal fats, excessive unsaturated fatty acid might not be favorable in the meal.
(5)Iron and calcium: Anaemia at various degrees can happen to old women, its reason is complicated, include the stomach capacity to reduce, inner factor, absorbability to the iron, deficiency of hematopoietic function, vitamin C and microelement of gastric acid and stomach,etc. may have something to do. But in general cases, the quality of the iron is a primary problem, the absorption rate of iron that animal's muscles and the blood offer is higher than the plant food, this must be paid attention to. It is softened that old women are easy to be osseous, the bone density is reduced, so that osteoporosis appears, this not only relates to hormone, vitamin D also relate to supply of calcium. Calcium of milk and dairy products has better absorption rates than calcium in the plant food. The total amount of supply of calcium is unsuitable to be less than the adult's standard, calcium that old women take in every day should not be less than 800 milligrams.
(6)Salt: It is should less in the elderly salt, every day generally 5 grams is should. Hypertension, coronary heart disease patient should limit in under 3 grams.
(7)Vitamin: Supply and young people of the elderly vitamin. In the nutrition survey of the elderly, often find vitamin A and b clan vitamin take in low. Vitamin C is also very important to the old age, but vitamin A and d are not the more, the better.
