Nutritional value of apple 1: nutritional value of pectin
Pectin in apples can reduce the content of total cholesterol and bad cholesterol. In an animal experiment, the researchers divided guinea pigs into two groups. A group of guinea pigs with normal cholesterol were fed apples in addition to three meals. Another group of guinea pigs raised with deliberately high cholesterol also added apples to their diet. The results showed that both groups of guinea pigs benefited a lot from eating apples, but in different ways: the cholesterol content of the former decreased by 20%, while the cholesterol content of the latter was close to normal. Even better, their bad cholesterol is reduced (bad cholesterol can block arteries and prevent blood from flowing to important organs, such as the brain and heart).
German scientists have found that pectin in apples can lower cholesterol. After a long-term investigation, Dutch scholars found that people who eat 1 apple every day have increased bile excretion and bile acid concentration, which is helpful for the liver to excrete more cholesterol. French researchers have come to the conclusion through experiments that eating apples can reduce the cholesterol content in blood and increase bile secretion and bile acid function, thus preventing cholesterol from precipitating in bile to form gallstones. Experiments show that more than 50% of people who eat apples regularly have lower cholesterol content 10% than those who don't eat apples. Researchers in Finland have conducted experiments on people. The results show that people who eat two apples a day can reduce their cholesterol by 16%.
On the other hand, pectin in apples can inhibit the abnormal peristalsis of intestines and slow down digestive activities, thus inhibiting mild diarrhea. Pectin can also promote the excretion of lead, mercury and manganese in gastrointestinal tract, regulate the blood sugar level of human body and prevent the sudden rise and fall of blood sugar.
Nutritional Value of Apple Ⅱ: Nutritional Value of Fiber
The fiber element contained in apples can soften the feces in the large intestine, thus having dual functions of relaxing bowels and stopping bleeding; In addition, the fiber in apples is beneficial to the growth and development of children and can promote their growth and development.
There is a kind of water-soluble dietary fiber in apples, which can reduce the number of bad bacteria in the intestine and help beneficial bacteria to reproduce. The once popular "Apple Diet" is used to make people feel full and regulate the intestines, so as to achieve the effect of losing weight. Now many Americans regard apples as a necessity to lose weight. They go on a diet one day a week and eat only apples. This day is called "Apple Day".
Nutritional value of apples Ⅲ: Nutritional value of zinc
Zinc in apples is a component of many important enzymes in human body, which can enhance children's memory and promote their development.
Nutritional value of apples Ⅳ: Nutritional value of flavonoids
The research report published by Finnish researcher 1999 10 shows that flavonoids in apples are effective substances to reduce the incidence of cancer.
The nutritional value of apples V: the nutritional value of vitamin C.
American researchers have also proved that "taking vitamin C directly from fresh fruits is more effective than taking oral drugs". Vitamin C is the protector of the cardiovascular system and a healthy element for patients with heart disease. At the same time, vitamin C can effectively inhibit the formation of skin melanin, help eliminate skin pigmentation, increase heme, and delay skin aging, which has the effect of beauty beauty. Eating a red Fuji every day can meet most of the vitamin C that the human body needs every day.
Nutritional value of apples ⅵ: Nutritional value of organic acids
Apples are rich in organic acids, which can stimulate gastrointestinal peristalsis and promote defecation. According to botanists' experiments, if you eat an apple for 15 minutes, the organic acids and fruit acids in the apple can kill 99% bacteria in the mouth. Therefore, eating apples should be chewed slowly, which is not only beneficial to digestion, but also beneficial to oral hygiene and reducing human diseases.
The seventh nutritional value of apple: the nutritional value of "apple phenol"
Apple phenol has seven functions: first, it can resist oxidation and keep food fresh; The second is to eliminate odor, which can remove fishy smell and bad breath; The third is to prevent tooth decay; Fourth, it can inhibit the production of melanin and enzymes; Fifth, it can inhibit the occurrence of reactive oxygen species and prevent various lifestyle diseases caused by reactive oxygen species; Sixth, it can inhibit the rise of blood pressure and prevent hypertension; Seventh, it can inhibit allergic reaction and has certain antiallergic effect.
Nutritional value of apples ⅷ: Nutritional value of potassium.
Apple contains more potassium, which can be combined with excess sodium salt in human body and excreted. When the human body ingests too much sodium salt, eating some apples is beneficial to balance the electrolytes in the body.
Nutritional Value of Apple IX: Nutritional Value of Phosphorus and Iron
The phosphorus, iron and other elements contained in apples are easily absorbed by the intestinal wall, which has the functions of nourishing the brain, calming the nerves and helping sleep.
Nutritional Value of Apple X: Nutritional Value of Sugar, Lithium and Bromine
Apple contains sugar, lithium and bromine, which is an effective sedative and hypnotic without side effects.
The nutritional value of apples eleven:
Apples contain much more calcium than ordinary fruits, which helps to metabolize excess salt in the body.
Nutritional Value of Apple XII: Nutritional Value of Malic Acid
Malic acid can metabolize calories and prevent obesity in the lower body. Malic acid can also stabilize blood sugar and prevent senile diabetes, so diabetics should eat sour apples.
Nutritional value of apple XIII: other values
Modern people ingest too much protein in their daily diet, and these protein are broken down into amino acids, which makes most people's body fluids "acidic". Acidic body fluids will continue to accumulate in the body, making people feel tired and weak. Polysaccharides, potassium ions, pectin and tartaric acid contained in apples can neutralize acid radicals in acidic body fluids and reduce the acidity in body fluids, thus alleviating fatigue.
The aroma of apples is a good medicine for depression and depression. After many experiments, experts found that among many smells, the aroma of apples has the greatest impact on people's psychology and has obvious effect on eliminating psychological depression. Clinical application has proved that patients with depression have greatly improved their mood and relaxed spirit. After smelling the fragrance of apples, the sense of depression disappears. Experiments have also proved that insomnia patients can smell the fragrance of apples before falling asleep, which can make people fall asleep quickly and quietly. The pace of city life is very tense, and professional people are under great pressure. Many people have different degrees of tension and depression. At this time, picking up an apple and smelling it will relieve the bad mood and refresh your mind. Expectant mothers eat an apple every day, which can reduce the reaction during pregnancy.
People who eat more apples are much less likely to catch a cold than those who don't eat or eat less apples. Therefore, some scientists and doctors call apples "all-round healthy fruits" or "general practitioners". Now the air pollution is more serious. Eating more apples can improve the respiratory system and lung function and protect the lungs from dust and smoke in the air.
