Discussion on nutritional beauty food
In order to maintain the image quality of figure and appearance, reasonable eating habits are very important. Don't overeat and eat less snacks. If there is something wrong with the performance arrangement and you can't eat on time, you must make preparations in advance, and strive to make the digestive system work normally, the gastrointestinal peristalsis is rhythmic, the metabolism is stable, and your health is guaranteed.
Eat in ration, 30% in the morning, 30% in the evening and 40% for lunch. Eat slowly. Amylase in saliva can convert starch into sugar, which plays a primary role in digestion, reducing the burden on the stomach and facilitating absorption. Relevant experts have found that eating in the second half of the day has a greater impact on the body than in the first half. This is because insulin reaches the highest value of the day at night, which can promote a lot of fat deposition under the skin, so dinner should not exceed 30% of daily food intake, and breakfast should reach at least 30%. You just need to eat 80% full every meal. In recent years, foreign medical scientists have found that any soup is an appetite control agent. Because drinking soup before meals can slow down people's eating speed, excite the "satiety center" of the brain and weaken their appetite, so as not to eat too much, thus achieving the purpose of controlling fat.
Obesity is caused by overeating, eating a lot of calories, sleeping more and exercising less, and eating less calories. In order to pursue slim figure, some models blindly diet and gird their waists, and even the basic nutrition needed by their bodies is limited, which is harmful to their health. The key to diet weight loss is to correct bad habits and change the situation that calorie intake is greater than consumption. Fat is the easiest thing to make people fat. Excessive intake of food into fat will make people fat. Models who want to maintain a standard figure should eat less fat, especially animal fat. Peanuts, sunflower seeds and walnuts with high oil content should also be limited. Eat more cooked food, less fried food and less oil when cooking. Sugar contains a lot of calories, so eat less sweets to prevent excess calories from turning into fat. Should eat more vegetables, fruits, bean products, eggs, fish, poultry, lean meat and other foods rich in protein. Being used to eating cold vegetables has little damage to vitamins. If the fruit with more water is made into natural juice, it will not only taste delicious, but also greatly reduce the calories.
Adequate water in the body can induce diuresis, keep the skin moist and drink as much water as possible. Drinking water in the morning is an excellent fitness habit. If possible, drinking mineral water or health tea is beneficial.
Food cosmetology is a special method different from cosmetology and medical cosmetology. By nourishing viscera, nourishing qi and blood, dredging meridians, enriching blood and removing blood stasis, expelling wind and clearing away heat, cooling blood and detoxifying, moistening white and removing wrinkles, the purpose of health and beauty can be achieved.
Nutrition and beauty
As time goes by, things change, human beings thrive, society develops and changes, and people's pursuit of beauty is consistent. From "Laughing at the Whole City" by The Story Of Diu Sim in the Three Kingdoms to "If she only turns to laugh, there are hundreds of spells cast" by Yang Guifei in the Tang Dynasty, it is more like "sinking fish and falling geese" and "avoiding the moon and feeling ashamed of flowers". All reveal people's desire for beauty. Good things and good people will give people a good feeling.
For thousands of years, "thin face", "round fat", "slim", "plump" and "charming" have all become words to describe beauty, but no matter how these words change, health is the eternal standard of beauty. Health is inseparable from nutrition, which has become an important factor of beauty. It is the guarantee of health and the foundation of beauty to absorb all kinds of nutrients needed by the human body from all kinds of foods and ensure good material support for the body. The following is a brief discussion on several aspects.
(1) Health First of all, a healthy person may be beautiful. Health comes from balanced nutrition. People grow up eating food. From the embryonic stage to the end of life, people constantly absorb nutrients from the outside world to meet their own growth and development needs. If the nutrition is sufficient and balanced, the cells in the whole body will get enough nutrition for normal physiological metabolism, and all tissues, organs and systems can play normal physiological functions. People will appear energetic, quick-thinking, quick-moving and full of vitality. Then it looks beautiful. In our impression, children are all beautiful. Because most of them are healthy.
(2) Skin is the key to beauty. Mainly manifested in its luster and elasticity. Besides sunshine, humidity, pollution and other factors, nutrition is a very important internal cause. If a person is malnourished, her skin will be dull. This has been described in some literary works.
Protein is an indispensable substance for beautiful skin. Protein's main physiological function is to constitute and repair important components of human tissues. The surface layer of skin is epidermis, followed by dermis and subcutaneous fat. If the human body lacks protein, the supply of epidermal cells is insufficient and the cells are not closely arranged. On the one hand, it accelerates water loss and makes the skin dry, on the other hand, it relaxes the skin; If the dermal layer lacks protein, the collagen synthesis in the dermal layer, which shows the elasticity and color of the skin, will decrease, thus the elasticity, color, softness and adaptability of the skin will decrease. Therefore, the human body must have enough protein supply.
Vitamin C is involved in the synthesis of collagen, which plays an important role in maintaining the nutrition of blood vessels. Vitamin C deficiency will affect the synthesis of collagen and easily lead to subcutaneous and mucosal bleeding and cyanosis. In addition, vitamin C has an important antioxidant effect and can scavenge free radicals in the body.
Free radicals are the product of normal metabolism of cells, and external environment such as sunlight, pollution, radiation and drugs can also produce free radicals in the body. Excessive free radicals in the body are not only the killer of human health, but also the enemy of beauty. Excessive accumulation of free radicals will destroy the cell structure, free radicals will attack the cell membrane, granular glands and genetic genes, and the accumulated damage will gradually lead to cell degeneration and death. When there are too many free radicals in fat, fat metabolism is disordered, which is reflected in the formation of black spots on the skin surface. Vitamin C and vitamin E are both important substances in human body that can resist oxidation and free radicals. Therefore, for beauty lovers, it is undoubtedly not to be missed to take enough vitamins C and E.
Many people will suffer because they are young and have freckles and dark spots on their faces. An important reason for freckles in adolescence is that in the process of fat metabolism, due to insufficient nutrient intake and lack of many substances that play an important role in fat metabolism, subcutaneous fat metabolism is disordered, which is manifested on the skin surface. So vitamins and minerals are essential for smooth and clean skin. Vitamin B2, in particular, is a component of many important coenzymes in the body and plays a very important role in fat metabolism. Vitamin B2 deficiency in the body can cause seborrheic dermatitis. It is common in areas with strong sebum secretion, such as nasolabial groove, jaw, brow and behind the ear. The affected skin has increased sebum, mild erythema and fatty yellow scales. Also, under the condition of insufficient and unbalanced nutrition, capillaries, nerves, hair follicle sweat glands and cortical glands in the dermis may cause abnormal skin conditions. In addition, vitamin A also plays an important role in protecting skin and mucosa. Adequate vitamin A can prevent rough and dry skin and ensure good skin nutrition.
(3) Losing weight has long been a hot topic in today's society. But there are also many misunderstandings about losing weight. Many people suffer because they don't know how to exercise correctly. Generally speaking, if a person has a regular diet and a balanced and reasonable nutrition, her figure should be normal. Many people with high body weight consume too much energy, such as carbohydrates or fat, but the enzymes that decompose and utilize these energies are insufficient due to too little intake of vitamins and minerals, and at the same time, they lack corresponding exercise to consume these energies, which leads to the accumulation of energy into fat in the neck, waist and buttocks, giving people a bloated feeling. In diet, we should eat more foods rich in dietary fiber, various vegetables and miscellaneous grains to reduce the absorption of fat. In addition, for obese people, vegetable oil with high unsaturated fatty acid content should be selected when cooking, and animal oil with high saturated fatty acid content should be banned. Unsaturated fatty acids can also reduce the cholesterol content in blood.
Among the factors affecting height, nutrients are particularly important. There are two peaks in human growth and development: infancy and adolescence. During this period, comprehensive and balanced nutrition is the key to meet the growth and development of the body, among which protein and calcium have great influence on the height.
(4) Detoxification The human body is an organism. It constantly absorbs nutrients from the outside to meet the needs of metabolism all the time. Food ingested from the outside is digested and absorbed, nutrients are transported to cells of the whole body through blood circulation, and metabolic wastes are excreted with blood circulation. However, if dietary fiber intake is too small, mental factors and other reasons lead to constipation, metabolic wastes, including some toxic substances, will stay in the intestine for a long time and be reabsorbed into the blood circulation, and some blackheads or black spots will appear on the face, which will affect the appearance.
Among all nutrients, dietary fiber is extremely important for detoxification. With the continuous improvement of people's living standards, people's diet is becoming more and more particular. Too fine food will lead to a serious lack of dietary fiber.
There are a large number of bacteria in the human intestine, most of which are beneficial bacteria and a few are pathogenic bacteria. Dietary fiber can promote the proliferation of intestinal beneficial bacteria and inhibit pathogenic bacteria, thus improving the intestinal environment and enhancing the immunity of the body. At the same time, high-quality dietary fiber has a strong water absorption function, and its volume is highly expanded after full water absorption, which is beneficial to softening stool, increasing the volume of intestinal contents, promoting intestinal peristalsis, enhancing mechanical stimulation to intestinal wall and increasing defecation. At the same time, it promotes the excretion of toxic metabolites, partial lipolytic products, bacteria and viruses and their toxins in the intestine. This not only reduces the chance that these toxins are reabsorbed into the blood circulation and appear on the skin, which affects beauty; It also reduces the incidence of some "rich diseases" such as hypertension, coronary heart disease and diabetes.
(V) Spiritual Nutrition The family's edification, school education, social edification and the baptism of nature that a person has experienced all his life will form his world outlook and his temperament. A person's growing environment always feeds him conceptually, that is, spiritual nutrition. Therefore, a person who absorbs nutrition in a positive and sunny environment from an early age will better show the beautiful side of life. Only by establishing a healthy concept, taking comprehensive and balanced nutrition and having a healthy body can we have the foundation of a good mood and educate the next generation to have a peaceful mind and physical and mental health.
Finally, cosmetic measures can undoubtedly solve superficial problems, and it is understandable to use some skin care products or even cosmetics, but they cannot bring fundamental changes to the appearance. For example, in our life, we often see some people, especially some ladies, take measures that should not be taken on their faces, and we can no longer see that kind of soft and shiny healthy skin. The body is an organic whole. In the long run, constant self-improvement has created an elegant temperament. From the inside out, charming figure, healthy and smooth skin and beautiful breath emitted by abundant energy are the keys to staying young forever.
There is no shortage of beauty in the world, but discovery. There is no shortage of beautiful looks in the world, but thinking. Many people who love beauty have never really thought about it. In fact, your appearance has an important relationship with the food you eat. Beauty is eaten. The factors that form beauty are comprehensive, but from a certain point of view, the factors that form beauty can also be quantified. The reference intake of dietary nutrients for China residents clearly indicates the reference intake of various nutrients needed by the human body, and comprehensive and balanced nutrition is of great benefit to health. I believe that more and more people will realize the importance of balanced nutrition, learn more about nutrition, eat healthy, eat beautiful and eat a beautiful new life.
Nutrition and beauty
Protein, fat, sugar, inorganic salts, trace elements, water, cellulose and other nutrients in food are essential nutrients for human health and facial beauty. The main source of these nutrients is food. Therefore, a comprehensive and reasonable intake of balanced nutrients from food is the most important material basis for beauty and fitness. On the contrary, if you don't pay attention to diet, such as dieting, partial eclipse, picky eaters, monotonous diet and so on. , will affect the intake of nutrients in food.
All women want their skin to be moist, delicate, tender and elastic. However, some people's skin is unsatisfactory, rough and dull. Analysis of the reasons, on the one hand, is related to the influence of genetic factors and diseases, on the other hand, it is related to acquired nutrition and maintenance. Modern scientific research has found that the smoothness of skin is closely related to the content of hyaluronidase in dermis. Hyaluronidase is closely related to the secretion of androgen. Scientists have recently found that when the estrogen secreted by the ovary increases, estrogen will combine with some specific receptors in the dermis, thus promoting the formation of aspartase. This enzyme can promote the skin to absorb moisture, trace elements, vitamins and other nutrients, making the skin moist, smooth and delicate. Water content: the water content of human tissue fluid is 72%, and that of adults is 58% ~ 67%. When the water content of human body decreases, it will make the skin dry and the secretion of sebaceous glands decrease, which will make the skin lose its elasticity and even wrinkle. Therefore, in order to ensure water intake, normal people should drink no less than 1000 ml per day. Potash-containing food: Potassium is essential for maintaining the pH of skin and body, maintaining the osmotic pressure in cells and normal metabolism. The daily potassium requirement of normal adults is 2 ~ 4g. Main food sources: bran, peas, soybeans, potatoes, sweet potatoes, radishes, pickled mustard tuber, peanuts, kelp, laver, dried pork floss, coffee and tea flavor. Foods containing vitamin A: Vitamin A can make eyes bright and skin moist and delicate. The main food sources: animal liver (dog liver should not be eaten too much), whole milk and its products, yellow-green vegetables, red sweet potatoes, carrots, green peppers, pumpkins and so on. Foods containing vitamin B2: Vitamin B2 is also called riboflavin. Its function is to maintain normal metabolism of skin, make skin smooth and delicate, smooth wrinkles, reduce pigments and eliminate spots. The main food sources: animal liver, kidney, lean meat, milk, eggs, soybeans and their products, and green vegetables. Foods containing vitamin B 1: Lack of vitamin B 1 can cause mucosal allergy and skin inflammation. The main food sources: animal offal, meat, beans, peanuts and brown rice. Drinking a lot of tea or overeating carp, herring and shrimp will affect the absorption of vitamin B 1. Foods containing vitamin C: Vitamin C is an antioxidant, which can reduce skin pigmentation and prevent melanin production, thus restoring the original white and smooth color of tanned skin. Excessive intake of vitamin C preparations can lead to stones or ulcers. The main food sources: oranges, oranges, pomelo, fresh dates, walnuts, strawberries, plows, cauliflower, lettuce leaves, lemons, tomatoes, hawthorn and various dark vegetables. Foods containing vitamin D: Vitamin D can prevent mild rickets in children and osteoporosis in middle-aged and elderly people. Main food sources: marine fish, animal liver and egg yolk, cream, cheese, cod liver oil, etc. Foods containing vitamin E: Vitamin E can improve the absorption rate of vitamin A, reduce and prevent the production and deposition of lipofuscin in the skin, prevent facial acne of teenagers, and have the functions of skin care, beauty care, anti-aging and longevity. The main food sources: vegetable oil, soybean and its products, mung beans, red beans, black sesame seeds, walnuts, duck eggs, garlic, spinach, crucian carp and shrimp. Foods containing fiber: Constipation can cause various symptoms and induce various diseases. Constipation can also make the face yellow and lose its due luster. Foods rich in cellulose can prevent constipation. Mainly: all kinds of vegetables, fruits and non-refined food. Foods rich in iron and zinc: ruddy skin, need plenty of blood. Iron is the main component of hemoglobin in blood. Zinc is also an indispensable trace element in the body and participates in various physiological activities of the human body. The content of zinc in skin is the highest, accounting for more than 20%, which determines the smoothness and elasticity of skin. There is a saying that "the skin is galvanized". Therefore, we should eat more foods rich in iron and zinc, such as animal liver, egg yolk, kelp, sesame paste, lean meat, oysters, seafood, etc., to promote skin fitness. Alkaline food: Rough skin is often caused by high blood acidity. Fish, meat, poultry, eggs and grains eaten in daily diet are all physiologically acidic. Physiological acidic food will increase the content of lactic acid and uric acid in the body and blood. When organic acids cannot be excreted in time, they will erode sensitive epidermal cells and make the skin lose its tenderness and elasticity. The content of alkaline inorganic salts in fresh vegetables and fruits is high, such as calcium, sodium, magnesium and potassium. Eating fresh vegetables often can make your body full of alkaline substances. The acidic substances in the body quickly neutralize and form non-toxic compounds to be excreted, which keeps the blood in an ideal weak alkaline state and keeps the skin smooth and moist. Therefore, we advocate a reasonable combination of vegetarian food and vegetarian food, and adjust the proportion of vegetarian food according to different age stages. Adults should be vegetarian in diet, get as much cystine and tryptophan as possible from plant protein to prevent skin roughness, keep the water content of skin at around 10%, delay skin aging and change skin roughness. Eat more physiological alkaline foods to make your skin smooth and beautiful.
Foods containing collagen and elastin: collagen can make skin cells plump, thus making skin plump, reducing wrinkles and making skin delicate and shiny; Elastin can enhance the elasticity of human skin, thus making the skin smooth and elastic. Foods rich in collagen and elastin include pig's trotters, animal tendons and pigskin.
