Chinese people's diet is mainly composed of cereals, supplemented by vegetables and fruits, so there is no risk of lack of dietary fiber. However, with the improvement of living standards, the degree of food refinement is getting higher and higher, and the proportion of animal food is greatly increased.

In some big cities, the proportion of heat production from dietary fat has increased from 20% to 25% a few decades ago to 40-45% at present, while the intake of dietary fiber has decreased significantly.

This is that "life’s better, less fiber." It leads to some so-called "modern civilization diseases", such as obesity, diabetes, hyperlipidemia and so on. At the same time, there are some diseases related to the lack of dietary fiber, such as bowel cancer, constipation, and intestinal polyps. And their incidence rate is increasing.

Obesity is a phenomenon caused by excessive accumulation of fat in human body, which is not regarded as a sign of "health". Obesity not only affects physical beauty, but also brings inconvenience to life.

In addition, obesity is very easy to cause hypertension, hyperlipidemia, hyperglycemia, commonly known as "three highs"!

According to statistics, the incidence of cerebral embolism and heart failure in obese people is twice as high as that of people with normal weight. The risk of coronary heart disease is twice as high as that of normal weight. The incidence rate of hypertension is 2 to 6 times higher than that of normal weight. The incidence of diabetes is 4 times higher than that of normal people.

What's more serious is that the life span of obese people is significantly shortened. It is reported that a 45-year-old man who is 10% overweight has a life span of 4 years shorter than that of a normal weight person. According to Japanese statistics, the standard mortality rate is 100%, and the mortality rate of obese people is 127.9%.

The high blood sugar caused by obesity also threatens everyone's life and health, and the occurrence of obesity is largely related to the insufficient intake of dietary fiber in human food.

Dietary fiber is an indispensable nutrient in the human diet. It has physiological functions such as improving human intestinal flora, improving blood sugar and fat metabolism, lowering serum cholesterol, and promoting mineral absorption. Therefore, it is necessary to add a certain amount of dietary fiber in processed food.

"Resistant dextrin" is a kind of low molecular weight water-soluble dietary fiber. According to the different content of dietary fiber, resistant dextrin can be divided into type 1 and type 2. It will not be digested and absorbed in the digestive tract and can directly enter the large intestine, since it contains anti-human digestive enzymes.

Therefore, it is a low-calorie food raw material, which can play various physiological roles as dietary fiber. The specific functions are as follows.

Hypoglycemia

Resistant dextrin can delay and inhibit the digestion and absorption of carbohydrates as well as improve the sensitivity of peripheral tissues to insulin.

Water-soluble resistant dextrin can form a gel to prevent the diffusion of sugars and delay its absorption in the intestines, thereby inhibiting the increase in blood sugar and blood insulin after the absorption of sugars.

In addition, resistant dextrin can change the secretion of hormones in the digestive tract, such as reducing the secretion of pancreatic juice, changing the digestive enzymes in the intestine. Consequently, it will be inhibiting the absorption of carbohydrates, and ultimately reducing blood sugar.

Hypolipidemic

Continuous intake of resistant dextrin can reduce the concentration of serum cholesterol, neutral fat and body fat. Resistant dextrin can also adsorb bile acid, fat and so on to reduce its absorption rate. What’s more, it can achieve the effect of reducing blood lipid, thus improving the lipid metabolism of patients with various types of hyperlipidemia.

In addition, water swelling of resistant dextrin can increase fecal volume and promote intestinal peristalsis, which has good preventive effect on constipation, hemorrhoids, colon cancer and other diseases.

Relaxing Bowel

As the resistant dextrin is not absorbed by gastrointestinal tract, it can directly reach the large intestine and be used by beneficial microorganisms in human intestinal tract. It can stimulate the growth and reproduction of probiotics, inhibit the harmful microorganisms in the intestinal tract, and provide beneficial regulatory substances for the human body, so as to improve the immune system and intestinal function of the human body.

At the same time, resistant dextrin is fermented by some beneficial intestinal bacteria to produce short-chain fatty acids, which produce more acid than the same dietary fiber. These short-chain fatty acids can prevent the growth and reproduction of cancer cells and effectively prevent rectal cancer.

As a kind of healthy food, resistant dextrin has the same powder characteristics and processing adaptability as granulated sugar. It is easy to use, with low viscosity and sweetness, good acid and heat resistance.
