New statement nutrition _'s nutrition guidance of language of the elderly's generation
The current society is towards the old age social development, people look forward to the longevity and health, people need, grasp more how go the intersection of food and scientific knowledge, meal Pyramid used to various food that eat act as scientific division every day people vivid.
At present, a lot of country include I national capital have each the intersection of guidance and national meal Pyramid of resident guide the people's reasonable meal. In these decades, the nutritionists are grasping, upgrading the knowledge of meal nutrition constantly. Recently, U.S.A. Tufts university researchers make new change and supplement to the middle-aged and old meal Pyramid.
1.Drink the water more: This is according to the middle-aged and elderly people's physilogical characteristic, namely thirsty and demanding to be less obvious than young people to the moisture, so often have danger of lacking water to add in the body. There are bottoms of the Pyramid that are taken share biggest grain such as bread, corn, rice and noodles,etc. to make up originally, there is important directive significance in meal of this resident in industrialized country or some developing countries of the west, it play a positive role preventing high candying, fatty high the intersection of heat and the intersection of hypertension, diabetes, cancer,etc. and a lot of modern emergence of civil disease that diet cause.
Now, the base of the Pyramid bottom is emphasized with water, fruit juice or other liquid (about 2000 ml) of 8 pieces of share Make up. Compared with the situation that the grain of cereal accounts for 6 pieces of share, the position where the moisture takes is even more important. New Pyramid that revise emphasize the elderly drink the water more, and organism lack the impact on various that the physiological supersession causes of moisture in order to prevent skin from to be dry stool secret to form.
2.Many fibers: In the new Pyramid, nearly each storey joins the cellulosic symbolic sign as much as possible. Eat more coarse food grain of the whole cereal, choose brown rice to eat more carrot, tangerine, apple but not only drinks carrot juice, orange juice and various other fruit juice instead of precise rice. Eat pod food at least twice every week, replace the food of meat like broad bean, French beans.
Because intestinal functions of middle-aged and elderly people fail gradually, these high fibrous food contains lower cholesterol and heat at the same time, thus has reduced the danger that the elderly suffer from vascular disease of the heart brain and cancer. The new Pyramid should pay attention to taking in the food of nutrition with high density to still remind the middle-aged and elderly people, 3 share that the vegetables are taken among them, 2 share that the fruit is taken, fruit of these vegetables includes: Spinach, the tangerine, yellow vegetables such as twenty potatoes and pumpkins.
The bright in colour fruit often contains a large amount of vitamin A originally, C and folic acid, such as strawberry, mango,etc.. Other nutrition density high choosing to have lettuce, peach and apricot,etc. besides apple, celery, cucumber by the intersection of cellulose and the intersection of content and high food.
3.Low-heat card: With traditional Pyramid the same one, a minimum one of some share of apex of the tower is still the absorption of fat, oils and sweet food that should recommend being limited, if it is high to fry food, cake, biscuit, fast food and hot card of various snack in more Shan but there is few nutriment, the elderly should not eat more. The supply of protein should pay attention to matching each other, thus accomplish the meal of equilibrium, if the mutual matching of cereal, beans, red meat, poultry egg reduces the absorption of saturated fatty acid and cholesterol.
4.The supply of the special nutriment: Middle-aged and elderly people's activity and appetite are reduced, in order to keep their weight, physiological supersession need and health state, require that must offer the sufficient special nutriment every day, for example offer the polyphenoils in order to prevent free radical that forms along with old age from damaging and old and feeble, the ones that offered enough vitamin D and calcium to protect the skeleton are stalwart, offer the food of irons with abundant content in order to prevent anaemia, offer abundant folic acid come maintain mental activity plentiful and reducing soldiers and neutralizing the emergence of heart disease.
5.Some nutrient needs supplementing extraly: Because middle-aged and elderly people health and the intersection of supersession and function subside, influence middle-aged and elderly people to some necessary absorption of nutriment, absorb and living beings utilize, the nutrient that so the middle-aged and elderly people need to supplement some organisms extraly to need, in order to respond to the request that the organism is healthy. The new Pyramid has held up a flag to show things in the top department of original Pyramid as waking up, it needs extra and some supplementary nutrient to remind people.
May threaten every middle-aged and elderly people because of osteoporosis, it is nearly as high as infant and pre-school children in the ill rate of anaemia of the elderly of our country, 1/3 of the old persons will present the gastric acid, peptic secretion reducing and withering gastritis gradually, and lead to the fact from this that reduces to the absorption of vitamin B12 and iron in the food. For this reason, the intersection of calcium and preparation and vitamin D supplementary skeleton it loosens to be essential to prevent from, can help the organism to keep the normal neural function reducing dull-witted emergence while supplementing vitamin B12.
But pure B12 additive can be absorbed very good, supplements iron pharmaceutical and has obvious curative effect in preventing and curing anaemia. But it is too supplementary to replace the choice of healthy food that the nutritionist still thinks vitamin, if a cup of milk is the calcium, potassium and vitamin B12 best sources of middle-aged and elderly people every day.
