"All-food" pop "eat grapes without spit grape skin"
Experts say that if they want to “eat whole foods and get all the nutritionâ€, they need to have two levels of nutrient absorption and food safety.
"Eat grape does not spit grape skin" is no longer a jingle, in the concept of "the whole family", eating grapes not only do not spit grape skin, and grape seeds have to be swallowed together. Is this so subversive "Total Food Concept" correct? This reporter interviewed a number of nutrition experts in Nanjing.
The "all-family race" is a concept.
The reporter enters the words "whole family" in the search engine. According to Baidu's encyclopedia, the "all-family" refers to people who insist on eating whole food. "Eating grapes does not spit grape skins". Eating bananas is no longer "skinned and eaten." They also like to "swallow the dates." Today, more and more urban people are joining this rank. They believe in "full food, full nutrition" and insist on eating whole foods to get all the nutrition. Allegedly, as a food culture, "full food" first emerged in Western developed countries and gradually expanded to the whole world.
Only eat leaves do not eat roots, stems, eat fruit only eat the pulp and discard the skin, kernels, fruit seeds, are all a waste of food essence. “The Whole Family†believes that these foods contain vitamins, minerals, cellulose, and plant bios. "It is a compound naturally secreted by plants. It is said to be an important material for plants to protect their lives. If people take it for a long time, they can resist oxidation, eliminate free radicals, and delay aging."
"With leash seeds" to eat more nutritious?
Mou Baoqing, an associate professor of nutrition and food hygiene at Nanyang University, told reporters that the exact name of “plant biochemistry†should be phytochemicals. However, experts say that this type of argument is controversial, at least for the time being, there is no authoritative research data in this field to support the statement that plant biochemicals “have long-term ingestion, can resist oxidation, eliminate free radicals, and delay agingâ€.
The “all-family†pays attention to “eat even belt seeds†when eating, and eat whole foods to get all the nutrition. However, Li Qun, director of the Department of Nutrition of the People's Hospital of Jiangsu Province, told reporters that food is not all the nutrients are in the skin and seeds, but it is completely unnecessary to deliberately pursue “complete foodâ€. "Although many people will misunderstand when they eat, but as long as one day's food is eaten according to the recommendations of a balanced diet pagoda, it is basically able to meet the nutritional needs of the human body. So far, there is no one kind of disease because of eating skin. Or because of not eating skin."

Peel has some nutrients but also pesticides
The reporter learned that the "fruit nutrition theory" advocated by the "full family" has to go through two levels of "nutrition absorption" and "food safety." "If apple skin is accidentally encountered, it may have more harmful substances if it accidentally encounters the 'bag apple'," said Li Qun. "Apple's main nutrition is still in the meat, not in the skin.
Mo Baoqing, associate professor of Department of Nutrition and Food Hygiene at the Department of Health, believes that the banana peels greeted by netizens have some effects on the gastrointestinal tract. However, if the bananas grow longer, the pigments will also change and cause mold. The breeding of the patients.†Wang Dongxu, deputy director of the Department of Nutrition, Nanjing Hospital of Integrated Traditional Chinese and Western Medicine, introduced the “Watermelon Chui Yi†with Qingshu, antipyretic, thirst-quenching, and urination. It is not a complete sense of watermelon rind. A planer knife is used to plan the cyan layer containing the waxy green skin and dry it, which is to say that the watermelon is Cuiyi (or watermelon blue).
According to Wang Dongxu, deputy director of the Department of Nutrition of Nanjing Hospital of Integrated Traditional Chinese and Western Medicine, even the roots of some of the ingredients are nutritionally nutritious, but they can only be absorbed after manual treatment. Otherwise, nutrient intake is very limited and may even be detrimental to health.
Raw swallowed grape seeds cannot be digested as well as grape seed oil
In the concept of “the whole familyâ€, grape skins are rich in resveratrol, not only can prevent cardiovascular and cerebrovascular diseases, but also have strong anti-cancer ability; grape seed contains a large number of polyphenols such as flavonoids, Procyanidins, etc. These are all strong antioxidants. Mo Baoqing told reporters that the phytochemicals in grape skins and grape seeds do have antioxidant functions, but “the shells of grape seeds are very thick and the whole meal is not conducive to digestion and absorption.†Li Qun, Director of Nutrition Department, Provincial People’s Hospital It is also believed that even if the grape seeds are crushed, they will still not meet the standards for digestion and absorption, and will eventually be discharged with fecal matter. And eating grape seeds will make the tongue numb, because it contains a lot of tannins, which will coagulate the protein on the tongue, mouth and esophagus, producing a strong astringency.
Mo Baoqing suggested that the whole family should choose to swallow grape seed instead of choosing grape seed oil that is hot in the market. “The linoleic acid content of grape seed oil is over 70%.†The reporter learned that linoleic acid is a fatty acid that the human body can not synthesize but cannot be synthesized by the human body. At the same time, grape seed oil can also prevent cardiovascular diseases and reduce human serum cholesterol and blood pressure.
Banana peel crude fiber helps to excrete gastrointestinal bad but become burden
Crude fiber is the most important “nutritional selling point†for fruit peels, typical of banana skins.
Wang Dongxu, deputy director of the Department of Nutrition of Nanjing Hospital of Integrated Traditional Chinese and Western Medicine, said that if the relationship between the fibrous tissue of food and nutrition is somewhat far-fetched. First of all, not all fibrous tissue contained in foods can be called the dietary fiber we often say. Second, even dietary fiber mainly refers to food nutrients that are generally not easily digested. Here is a key sentence: It is not easy to digest! The dietary fiber mainly comes from the plant cell wall, and the nutritional effect is far lower than other effects. The main function of dietary fiber is not its nutrition, but it is mainly a strong ability to combine with water. This effect can increase the volume of feces in the intestine, speed up its transport speed, and reduce the time when harmful substances contact the intestinal wall. If you have a bad stomach and gastrointestinal tract, but it is hard to stuff a lot of crude fiber, it will increase the gastrointestinal burden.
