Fruit juice market, currently there are three: nothing to do with the fruits of fruit drinks, fruit drinks containing a certain proportion, pure fruit juices. And the same kind of analysis in the end what the "health" and "unhealthy."
Juice counts one: high-calorie soft drinks have
According to U.S. media reports, more and more doctors, scientists and public health officials believe that the natural fruit juice drink may not be good for health. Natural fruit juice drink caused obesity, with Coke and other soft drinks and alcoholic drinks saccharin, no difference.
More than a glass of fruit juice to the sugar together. If calculated by the same weight, fruit juice or even higher than the calories contained in soft drinks.
You probably can not think of a cup 240 milliliters of pure fruit juice generally have about 100 calories of heat, than recognized as the "fat drinks" Coke is also higher.
U.S. Department of Agriculture data, containing 112 calories a cup of fresh orange juice, apple juice contains 114 calories, grape juice contains 152 calories. The same amount of Coca-Cola contains 97 calories, Pepsi contains 100 calories.
Vice President, Shanghai Sixth People's Hospital, Shanghai Diabetes Institute director Professor Jia Weiping image to explain: usually eat an apple to feel full, and can only squeeze four small amount of apple juice, even if all the drinking is also do not feel full. But it is precisely this cup of juice, heat it contains much higher than would an apple. "Especially in fruit drinks, fruit juice drinks is also a considerable number of added sugar." Fang endocrinologist six homes, the "large number of current international juices and juice drinks on the research, many studies are designed to protect children troubled by the type 2 diabetes. "
Juice counts II: more increase in fat accumulation
In addition, the juice contains large amounts of fructose. University of California scientists Stanhope noted that intake of fructose may increase the risk of heart disease and type 2 diabetes risk, because fructose is more likely than glucose by the liver into fat.
Many studies indicate that fruit juice is good for health, and reduce body weight. In 2008, a survey of 3618 children aged 2 to 11 survey found that drinking at least 6 ounces a day (about 177 ml) juice of children, body weight than those who do not drink fruit juice full of children light, the body will also have more vitamins and minerals. However, many experts believe that this data simply reflect the juice and the correlation between healthy eating, rather than causality.
Yale University Lutheran Center for Food Policy and Obesity Browner, director pointed out: "The children drink more fruit juice are more likely to eat breakfast, and children eating breakfast and weight lighter than the children do not eat breakfast."
Juice counts III: 8 days let you rely on sweet drinks
In addition, some experts worry that children drink plenty of sweet drinks will make them grow up to prefer sweets. A Dutch study in 2004 found that children aged 8 to 10 eight days in a row of orange juice to drink sugary, the more preferred than sweet drinks. They also used orange juice because of the sweetness of the drink.
Juice counts four: artificial colors of IQ
Both fruit drinks, fruit drinks or low concentrations, will use artificial colors - bright colors will make the consumer perception of fruit drinks and linked, when the juice content not to drink to have a little fun when fruit color , cheap artificial colors is the best choice.
And artificial colors on the human body, especially children's injuries in modern nutrition, the long study.
University of Southampton in 2008, researchers found that children had 100, synthetic pigment will affect children's mental development. Changyin juice children drink less, and often loss of appetite, hyperactivity and morose, lack of height and weight.
Tartrazine and sunset yellow, and other chemical additives make children of 7 IQ by 5 points. Mushy peas and lemon is a yellow cotton candy with food coloring in its prohibition of children under 3 years of age to use food and drink; and Quinoline Yellow is the fruit drinks, soft drinks and cold capsules often add food coloring. Widely used in fruit juice preservative sodium benzoate have damage to the body.
Excessive pigment into the children's body, easy to cool in their immature gastrointestinal mucosa, causing loss of appetite and indigestion, a variety of enzymes interfere with the function of the body, metabolism and physical development of adverse effects.
Clearly, the use of artificial colors, sweeteners, sour agents, spices and other food additives produced, does not contain any fruit juice fruit drinks almost no nutritional value.
Five counts juice: fruit juice will make you anemic?
In addition, the fructose will also hinder the body's absorption of copper. The lack of copper will affect the formation of hemoglobin, causing anemia. Albert Einstein Medical Center for more than 100 cases of anemia in children were retrospectively found that 80% of them are drinking fruit juice habit.
National survey data show that addicted to drink fruit juice present polarization physical development of children, or too thin, or obese. As the sugar content of fruit juice drinks too much, children can derive after drinking a lot of heat, thus affecting the eating dinner. If this trend continues, will inevitably lead to protein, certain vitamins, minerals and trace elements intake, affecting physical and mental development.
Therefore, the U.S. Medical Association recommended children 1-6 years old children drank no more than 4-6 ounces of fruit juice (one ounce is 28 ml); 7-18 year-olds no more than 8-12 ounces.
Juice counts six: you more susceptible to cancer
After being filtered juice of fruits and vegetables were thrown away mainly insoluble fiber. This insoluble fiber on the human body what effect?
This fiber is not heat, does not dissolve in water, there can not be completely in the gastrointestinal digestion, vitamin B, can hold full GI, is very effective and safe weight-loss food.
It enters the body, will remain intact into the large intestine, become food for bacteria in the large intestine. Metabolism of bacteria will produce some of the beneficial ingredients. Insoluble fiber maximum benefit is to promote the large intestine peristalsis, reduce the food in the large intestine residence time, prevent constipation and reduce the large intestine where bacteria convert food into toxic substances opportunities, but also dilute the food in the existing toxic substances, reduce opportunities for victims of the large intestine to prevent the occurrence of colon and rectal hemorrhoids. Food in the absence of such fibers suffering from colon cancer, rectal cancer will increase the chance.
WHO recommended intake of 25 grams of fiber each day, but according to the survey, most people are lower than this amount. In this sense, the fruit or vegetable juice, really throw is very good for human health, the fiber component.
In addition, the fiber can not be digested to provide "full" feeling, thus reducing the desire of people to eat other things, for the weight loss is beneficial.
Generally recognized as the world is the lack of sufficient modern diet of vegetables and fruits. The juice of fruits and vegetables lost to provide dietary fiber composition - this is the vast majority of people should be increased consumption. So, compare the value of fruit juice itself, eat fruits, do not drink fruit juice.
