Natural sugar: essential for human body to maintain life
All life forms on earth are composed of sugar molecules, fats and amino acids. Such as humans and food. About 500 grams of glycogen molecules are stored in the skeletal muscle and liver of an adult in order to provide energy for the human body at any time. Even meat contains "sugar", which is a certain proportion of carbohydrates.
I believe that many health-conscious friends are no strangers to carbohydrates. In fact, carbohydrates are the widely recognized name for sugar. If the sugar chain structure composed of sugar molecules is relatively simple, like glucose and sucrose, it tastes obviously sweet. If the sugar chain structure is complex, such as the starch contained in cereal and potato ingredients, it will not taste sweet. The sugar contained in natural foods is necessary for the human body to maintain life activities. The brain, nervous system, and heart muscle all use glucose as energy source.
Juice is actually a "blood sugar cannonball"
Many people think that carbohydrates are the main culprit for gaining weight, so they avoid staple foods, but feel that juice is very good for health. In fact, they are quite wrong. In terms of quantity, eating an apple and drinking a glass of apple juice, the body's intake of sugar is the same. The difference is that the glucose, fructose, etc. in the juice will enter the blood within a few seconds. So much sugar enters the human body at the same time, just like throwing into a "blood sugar cannonball", it will cause the blood sugar level to soar and insulin gushes frantically. When the sugar is "sucked" away by muscle cells and fat cells, the blood sugar level drops to the bottom like a roller coaster. Due to the rapid speed of this process, although the blood sugar rises, the brain has no time to secrete the corresponding hormones and give a "satisfaction" signal.
And if we eat an apple, if we chew it carefully, it will take at least 5 minutes. Not only glucose and fructose can enter the blood relatively smoothly, but also the carbohydrate that does not produce energy and does not stimulate insulin secretion-dietary fiber. This will make the "rising and falling" curve of blood glucose after a meal more rounded and smoother.
Because of this, many girls with small appetites will feel full after eating an apple. Studies have shown that if you replace the juice you drink daily with white water, you can reduce the risk of diabetes by 8%.
Such as white sugar (cane sugar extracted from sugar cane, sugar beet, etc.), rock sugar, brown sugar, glucose, honey, fructose, maltose syrup, sugar in freshly squeezed fruit juice, etc.
Free sugar: a stumbling block to health
Free sugar will increase the overall energy density of the diet, resulting in excess energy. The intake of free sugars by drinking sugar-sweetened beverages will reduce the intake of more suitable nutritious calorie foods, leading to unhealthy diets, weight gain, and aggravating the risk of non-communicable diseases. In addition, excessive intake of free sugars can also lead to protein, high-quality fats, minerals, vitamins, phytochemicals, and even water (eating ten biscuits consumes much less water than eating a bowl of rice) and so on. Insufficient intake of nutrients causes the strange phenomenon of obesity and malnutrition, leading to delayed growth and development. Academic research has also proved that "sweetness" can significantly increase the probability of dental caries, leading to imbalances in the intestinal flora, giving "bad bacteria" the upper hand, making probiotics worry about survival and causing problems such as constipation or chronic diarrhea.
Go with nature and eat natural sweets
People prefer sweets because of their fast energy supply and good taste. When the "Guru family" in the movie "Crazy Primitives" came to the fruit farm of "Modern People", the feeling of happiness could overflow the screen to infect every audience.
In fact, there are many natural foods in natural forms that have not been ground or squeezed to give us a sweet taste. Strawberries and mulberries in spring; watermelons and lychees in summer; grapes and pomegranates in autumn; sweet potatoes and chestnuts in winter can give you imaginative sweetness.
