First, a certain food or a certain kind of food is most suitable for certain (special) people, such as infants, young children, diabetics, people who are seriously deficient in certain nutrients, etc. Due to physiological reasons, the dietary structure required by this group of people is obviously different from that of the general population.
Secondly, the nutritional components of foods made for this group of people are significantly different from those of comparable ordinary foods, and some of them have low or high nutritional components. For example, the nutritional composition and content of infant formula milk powder required by non-breastfed babies are significantly different from those consumed by adults. Foods for special dietary uses can only be called if two conditions are met.
The difference between foods for special dietary uses and health care products, medicines and ordinary foods.
Foods for special dietary uses: To provide special nutrition for special people, that is, to provide special physiological nutrients (which can't be ingested from ordinary daily meals). As a food supplement and dietotherapy of modern science and technology, special dietary products follow the principles of regulating nutrition, regulating health and homology of medicine and food, and draw lessons from the formula principle of Chinese medicine, which provides special and rich nutrients that are easy to lose and difficult to obtain for special people, and at the same time regulates body functions, with the lowest metabolic burden and the highest safety.
The raw materials of special dietary food all come from the essence of more than a dozen or even dozens of natural substances. Advanced microecology and ultrafiltration technology are used to systematically strengthen or weaken, add or remove some ingredients for special people, so as to provide the most scientific proportion of nutrients that are easy to lose and difficult to obtain for special people.
Health food: Health food contains a certain amount of functional components (physiologically active substances), which can regulate human body functions by extracting, separating, concentrating or adding some high-purity physiologically active substances, so as to make it have specific functions (the third function of food); Health food generally has a specific range of consumption (specific population), and can claim health care function without treatment, but it cannot have any toxicity and can be eaten for a long time.
Ordinary food: it also contains physiologically active substances, which can not reach the concentration of regulating function in human body, and can not achieve curative effect because of its low content; Ordinary food does not emphasize the specific function (the third function of food), and there is no specific scope of consumption (cannibalism). Eating ordinary food directly can not only meet the nutritional needs of special people, but also bring a lot of unnecessary nutritional burden (saturated fat, sugar, etc. In addition, ordinary food can't meet the digestion and absorption of some special people and has a great metabolic burden.
Drugs: Drugs have a clear therapeutic purpose, clear indications and functional indications, can have adverse reactions, and have a prescribed use period.
To sum up, the special diet has the highest biological utilization value and the safest, and its biological indicators are very strict. From the source of raw materials to the processing technology, it is in accordance with the most stringent national standards, and there is no toxic side effect at all. Compared with ordinary foods and health products, special dietary products have the highest safety, the lowest metabolic burden and the strictest biological indicators.
classify
Geographically, foods for special dietary uses comes from land and sea.
Characteristics of special meals on land
Special dietary foods on land are simple in composition, slow in absorption, and difficult to understand in efficacy, which often cannot meet the nutritional needs of special people. Therefore, in recent years, medical researchers have turned their attention to the field of marine ecology on the road of exploring health and nutrition.
Characteristics of marine special meals
First, the ocean is a huge and continuous water body, and ocean currents, waves and tides make the ocean in an endless turbulent state; The harsh environment of high pressure, low temperature, darkness, lack of oxygen and strong corrosiveness in the ocean greatly increases the difficulty of marine development and puts forward high requirements for development technology.
Second, there are relatively few excellent enterprises focusing on the marine field in China, and the exploration of marine healthy energy started relatively late on land.
However, the advantages of marine ecosystems cannot be underestimated. Extracting active substances that are helpful to human health from the rich ocean undoubtedly proves that the exploration of human health has taken a big step forward. In the near future, marine special dietary food will soon become a healthy trend!
advanced technology
The raw materials of special dietary food all come from the essence of more than a dozen or even dozens of natural substances. Advanced microecology and ultrafiltration technology are used to systematically strengthen or weaken, add or remove some ingredients for special people, so as to provide the most scientific proportion of nutrients that are easy to lose and difficult to obtain for special people.
Compared with the resources on land, the formula of marine diet comes from deep-sea creatures, which has less pollution, strong active substances and is friendly to human body. So far, marine special diet is the most exquisite nutritional formula for human beings on the road of nutrition and health.
Compared with ordinary food, marine special dietary food supplements the nutrition needed by special people, and the effect of balanced nutrition is more obvious! The appearance of special marine diet will undoubtedly contribute to people's health!
