Nutrition and reasonable diet for middle-aged and elderly people is an extremely important part of health care for middle-aged and elderly people. Middle-aged and elderly dietary nutrition plays a role in preventing aging, multiple diseases in old age and prolonging life. Generally after the age of 50, the form and function of the body appear certain decline phenomenon, such as gland secretion reduction, metabolism slows down, resistance to reduce and so on. The delay in the appearance of the aging process and the degree of performance is related to many factors. Dietary nutritional status is one of the main factors.
I. Nutritional needs and dietary characteristics of the middle-aged and elderly:
1. Caloric energy The basal metabolism of the elderly is about 10-20% lower than that of the middle-aged. Due to the lowering of basal metabolism and the reduction of physical activity, the daily calorie requirement decreases by about 20% for those above 60 years old and about 30% for those above 70 years old. Generally speaking, the elderly daily intake of caloric energy 6.72-8.4MJ (1600-2000KCal), caloric intake to maintain a more desirable body weight is appropriate, easy to make the body fat, but should not be overly restrictive food and lead to malnutrition.
2. Protein Because the elderly catabolism is greater than anabolism, protein synthesis ability is poor, the utilization rate of protein intake is low. The supply of protein and amino acids should be balanced, so it should be supplemented with high-quality protein.
3. fat The elderly bile acid reduction, lipase activity is reduced, the digestive function of fat decreased, so the fat intake should not be too much; fat should be rich in polyunsaturated fatty acids, mainly vegetable fats. Cholesterol and cardiovascular disease also have a certain relationship, middle-aged and elderly people should eat less cholesterol-rich foods, but do not have to overly restrictive, moderate cholesterol on the body is beneficial.
4. carbohydrates because of the middle-aged and elderly people with low glucose tolerance, insulin secretion on the regulation of blood glucose weakened, easy to increase the phenomenon of blood glucose, there are reports that people eat more sucrose may be related to atherosclerosis and other cardiovascular diseases and the incidence of diabetes mellitus, so the middle-aged and the elderly people should not eat food with high sucrose; and fructose is easy to be absorbed by middle-aged and elderly people to utilize and the ability of fructose to turn into fat is less than that of glucose, the middle-aged and elderly people ingested food with a high level of glucose. Glucose, middle-aged and elderly intake of carbohydrates in addition to starch, should be fructose-based less sucrose.
5. Inorganic salts and trace elements Middle-aged and elderly people should be supplied with enough calcium and selenium. Calcium can prevent osteoporosis, but should not be too high to avoid unnecessary calcification. China's Nutrition Society recommends that the daily supply of calcium for adults is 800mg, which can already meet the needs of middle-aged and elderly people. Selenium is an important antioxidant, and has the role of cardiovascular protection, maintenance of myocardial health. In addition, selenium also protects the visual apparatus and anti-tumor effects. It has been reported that cataract patients and diabetic blindness after supplementation with selenium, found that visual function has improved. Iron intake also needs to be sufficient, because the middle-aged and elderly people's ability to absorb and utilize iron decreases, hematopoietic function decreases, hemoglobin content decreases, so iron deficiency anemia is easy to occur. It is reported that the prevalence of anemia among middle-aged and elderly people is about 50% in Beijing and 55% in Guangzhou. The cause of anemia in addition to insufficient iron intake, but also may be reduced with protein synthesis, vitamin B12, B6 and folic acid and other deficiencies. China's recommended daily dietary supply of iron for the elderly 12mg.
6. Vitamins vitamins in the regulation and control of metabolism, delaying the aging process is extremely important, so the elderly need to supply enough vitamins every day. The human body aging and immune function decline and free radical reaction enhancement, peroxide increase has a certain connection, and a variety of vitamins and its antagonistic effect. Vitamin A can promote immune tolerance, lymphoid organ proliferation and enhance natural immunity. Vitamin D promotes normal granulocyte osmotic differentiation, increases the role of macrophages and T cells, and prevents osteoporosis. Vitamin E is a free radical scavenger, vitamin E in the body's tissues can decline with age, leading to a decline in antioxidant capacity, causing aging. In recent years there have been many studies on vitamin E for anti-aging and improving immune function. It has been reported that the lack of vitamin E in animals with enhanced lipid peroxidation, the body cells can appear in a brown pigment particles, known as brown pigment, is the oxidative decomposition of certain intracellular components of the deposits, with the aging process in the body accumulation, commonly known as age spots. Supplementation of vitamin E can reduce the formation of lipofuscin in the cells, and can change the skin elasticity. Vitamin E deficiency also reduces the body's immune function. Adequate vitamin C can prevent vascular sclerosis in the elderly, promote cholesterol out of the body, enhance the body's resistance, in the body's humoral immunity and cellular immunity have an important role. The dietary characteristics of the elderly should be a small number of meals, regular quantitative, monthly meals should be as far as possible to meet the requirements of a balanced diet. Food variety should be diversified, protein sources focus on high quality, eat more green leafy vegetables, fruits, meals should be light and easy to digest, meals should be low salt, less sugar, less animal fat.
Two, nano-wake spirulina - the best food for health care of the elderly:
The world population to the aging development and the incidence of common diseases in the elderly increased, causing the attention of countries around the world, and actively develop and research the "senior food" is the trend of food development in the 21st century. The trend of food development in the 21st century. Nano wake-up Spirulina is a high-quality high-protein nutritional natural food, its protein content of up to 60% -70%; in the nano wake-up Spirulina contains 18 kinds of amino acids, the human body needs the eight essential amino acids have, and the balance of amino acids to fully meet the Food and Agriculture Organization of the United Nations (FAO) recommended the standard of ideal proteins, which improves the nutritional value of proteins. The cell wall of Spirulina Nano is thin and contains less cellulose, so the protein and other nutrients can be easily digested, absorbed and utilized, and its digestion and absorption rate reaches 86-98%. The fat content of Spirulina nanometer off wake up is only 6%, cholesterol content is very low, mainly in the presence of gluten sterol, which is very different from meat and dairy foods, and thus no animal protein brought about by the high cholesterol content of the problem.
In addition, nano wake up Spirulina fat is mainly unsaturated fatty acids, of which, the content of linolenic acid up to 13.79g / kg, γ-linolenic acid up to 11.97g / kg. γ-linolenic acid has the effect of lowering blood lipids, preventing atherosclerosis, maintaining vascular elasticity, reducing blood viscosity, promote blood circulation, to achieve the prevention and treatment of cardiovascular disease, reduce the incidence of stroke. Due to the high protein content, excellent quality, easy to digest and contain unsaturated fatty acids, low fat and other characteristics of nano-desiccated Spirulina, very much in line with the nutritional requirements of middle-aged and elderly people.
The content of vitamins in Spirulina is extremely rich, and there are many kinds of vitamins, such as B1, B2, B6, B12, E and K. Especially the content of β-carotene and vitamin E is high. β-carotene content is as high as 1,700mg/kg, which is more than 10 times that of carrots, and vitamin E is 190mg/kg, which is extremely important for anti-aging. These two substances have an extremely important significance in the fight against aging. Research shows that the increase of free radicals in human body is an important factor that leads to lipid peroxidation in tissues and accelerates cellular aging and even cancer; therefore, substances that can antioxidize and remove free radicals are also considered to have certain anti-aging and anti-cancer effects. β-carotene, vitamin E and vitamin C are medically recognized as the three major antioxidant micronutrients, and nano-detoxification of Spirulina is full of the two of them. β-carotene can be converted into vitamin A in the body, and vitamin A can protect the body from the effects of aging and cancer. Vitamin A, and vitamin A can protect the mucosal epithelium of organs, prevent various infections, and maintain normal physiology; β-carotene also has the role of scavenging free radicals, preventing tissue cytoplasmic peroxidation, and can enhance immunity. The physiological mechanism of vitamin E is mainly anti-lipid peroxidation, an indispensable component of a variety of antioxidant enzymes in the body, and has an important role in maintaining the activity of these antioxidant enzymes.
Nano wake up Spirulina iron content of up to 600-1050mg / kg, but also contains extremely rich in high-quality protein, vitamins and chlorophyll, minerals, etc., so on the prevention and treatment of iron-deficiency anemia has a positive effect on the taking of Spirulina is not simply a supplement to the iron, but to supplement the reasonable composition of the whole nutrition. It has been shown that vitamin A transformed by β-carrot is related to the synthesis of ferritin; Japanese scholars pointed out that chlorophyll can stimulate hematopoietic organs and strengthen the hematopoietic function. The content of these two kinds of substances in NanoDewake Spirulina is very high. Taking NanoDewake Spirulina can not only satisfy the supplemental needs of iron and various nutrient deficiencies, but also promote hematopoietic function, which is the best choice for the prevention and treatment of iron-deficiency anemia. We use purebred Wistar rats to replicate the iron-deficiency anemia model, and then use ferrous sulfate and three doses of spirulina mixed into the feed, the results after four weeks of three doses of nano-de-awakening spirulina feeding group of hemoglobin, erythrocyte counts, cellular pressure volume and serum ferritin increased significantly, which feed containing spirulina more than 8% of the group efficacy is the same as the control group of ferrous sulfate, and body weight recovery is better; With spirulina tablets for the treatment of 181 columns suffering from iron deficiency anemia in elementary school students, one month after the average hemoglobin value from 106.9g / L rose to 123.1g / L, serum ferritin from 20.2ug / L rose to 54.5ug / L, the efficacy is very obvious, and did not find any side effects. As the middle-aged and elderly people are prone to iron deficiency anemia, taking nano-detoxification of Spirulina to prevent and control iron deficiency anemia is also of great significance.
Japan's Tokyo National Medical University and Stomatology University of Stomatology Hospital lecturer Yamayaki application of spirulina treatment of senile cataracts, diabetic retinitis and hypertension retinal vascular sclerosis, etc. *** 480 cases, after half a year of observation, 90% of the symptoms are reduced, eyesight to varying degrees of restoration, suggesting that the spirulina to prevent and control vision disorders in old age has a certain efficacy.
Japanese scholars believe that middle-aged and elderly people consume more spirulina and exercise, is the secret of human longevity. Spirulina's health care significance lies in the consumption, the human body needs to supplement a variety of amino acids and nutrients once in place, conducive to metabolism, tissue assimilation, regulating the body's physiological functions, enhance immunity, improve physical fitness, so as to achieve the prevention of disease and promote the purpose of recovery. Spirulina contains a variety of anti-aging substances, these substances, on the one hand, through the role of anti-peroxides, eliminating free radicals, effectively slow down the cellular aging process; on the other hand, by slowing down the atrophy of the gonads as well as lowering blood lipids, preventing atherosclerosis, slow down the physiological aging process. Therefore, it can be said that nano de-awakening spirulina is the most ideal health food for middle-aged and old people to prolong their lives. It is reported that 73% of the consumers of Spirulina in Japan are people over 50 years old and 57% of them are women. Of the Japanese elderly who use spirulina, 45% use it for specific diseases, 28% use it to maintain physical health and good spirits, and 12% use it as a nutritional supplement. Among those who use spirulina for specific diseases, 22% use it for blood sugar, 15% for eyes and 14% for constipation. Japanese seniors do not see spirulina as a short-term measure, but rather as a way to maintain long-term health, with the result that their medical bills are much lower than those of Americans. Long-term use of spirulina also has the effect of removing age spots and chloasma from the face.
Third, the difference between nano de-awakening spirulina and ordinary spirulina:
The difference between nano de-awakening spirulina and ordinary spirulina lies in the nano de-awakening spirulina using advanced technology and special technology processing, in order to ensure that the original nutrients are not lost, so that its nutrients are more easily absorbed in the body, and the nutrient absorption of spirulina than the general increase in the nutrient absorption of 20-30%, close to 100% of the Absorption. In addition, after the de-awakening process, the taste is more suitable.
Four, a variety of diseases reference dosage:
Prevention and treatment of iron-deficiency anemia 5g per day, prevention and treatment of diabetes 20-30g per day, prevention and treatment of hypertension 10g per day, prevention and treatment of vision disorders of the elderly 10g per day, prevention and treatment of chronic gastritis and peptic ulcer 10g, prevention and treatment of liver disease 10g, prevention and treatment of cancer more than 30g.
Note: For the auxiliary treatment of various diseases take the amount must be large, its effect can be obvious.
