4 work efficiency

1, control blood lipid
Nowadays, the efficacy of dietary fiber has been proved, which can reduce the blood lipid level of people and animals, and greatly reduce the serum cholesterol and fat (triglyceride) of people and mice. If 5- 10g inulin is ingested every day, the serum fat can be reduced by less than 20%. Hidaka et al. reported that elderly patients aged 50-90 years ate 8g short-chain dietary fiber every day, and after two weeks, the blood triglyceride and total cholesterol levels decreased. Yamashita et al. fed 8g inulin to 18 diabetic patients for two weeks, the total cholesterol decreased by 7.9%, but HDL—- cholesterol remained unchanged. However, in the control group fed with food, the above parameters did not change. Brighenti et al. observed that 12 healthy young men added 9g inulin to their daily cereal breakfast for 4 weeks, the total cholesterol decreased by 8.2% and the triglyceride decreased by 26.5%.
Many dietary fibers absorb intestinal fat and form fatty fiber complex, which is excreted with feces, thus reducing blood lipid level. Moreover, inulin itself is fermented into short-chain fatty acids and lactic acid before intestinal end, and lactic acid is a regulator of liver metabolism. Short-chain fatty acids (acetate and propionate) can be used as fuel in blood, and propionate inhibits the synthesis of cholesterol.
2, lower blood sugar
Inulin is a carbohydrate, which will not lead to the increase of glucose in urine. It will not hydrolyze into monosaccharide in the upper part of intestine, so it will not increase blood sugar level and insulin content. Now research shows that the decrease of fasting blood glucose is the result of short-chain fatty acids produced by fructooligosaccharides fermentation in colon.
3. Promoting the absorption of minerals Inulin can greatly improve the absorption of minerals such as Ca2+, Mg2+, Zn2+, Cu2+ and Fe2+ ",and dietary fiber can combine with metal ions in the digestive tract. Any compound of inulin and minerals will degrade during fermentation, releasing minerals, thus effectively absorbing metal ions. In addition, the acid produced by fermentation reduces the pH value of colon by 1-2 units, which greatly improves the solubility/bioavailability of many minerals (such as calcium phosphate). Moreover, studies have shown that short-chain fatty acids, especially butyrate, can stimulate the growth of colonic mucosal cells and improve the absorption capacity of intestinal mucosa. Inulin can also improve the combination of calcium and protein in colon segment.
4. Studies on increasing intestinal bifidobacteria show that daily intake of inulin can greatly increase beneficial bacteria in colon (about 10 times) and reduce pathogenic bacteria and spoilage bacteria, such as Salmonella, Listeria, Staphylococcus aureus and Escherichia coli. Its mechanism is that inulin directly enters the large intestine without digestion and absorption, and is preferentially used by Bifidobacterium to produce acetic acid and lactic acid, which reduces the PH value of the large intestine, thus inhibiting the growth of harmful bacteria. Therefore, inulin is a proliferation factor of Bifidobacterium.
5. Anti-constipation and treatment of obesity Dietary fiber reduces the residence time of food in gastrointestinal tract, and increases the amount of feces, effectively treating constipation. Its weight-reducing function is to increase the viscosity of the contents and reduce the speed of food entering the small intestine from the stomach, thus reducing hunger and reducing food intake.
5 medical care
edit
First, inulin can reduce blood sugar and dilute blood sugar concentration.
1, blood sugar level decreased.
Eating inulin or drinking inulin concentrate on an empty stomach can immediately reduce blood sugar levels. Many people obviously feel the decrease of blood sugar in a short time. The following are the reports of 6 patients who ate inulin or drank inulin concentrate for 10 days:
(Note: The unit of blood sugar is mg/dl, which refers to the glucose content per deciliter. The glucose content per deciliter of normal people on an empty stomach is 80- 100 mg. Below this standard is hypoglycemia, above this standard is hyperglycemia. )
2. Relieve the symptoms of diabetes
When people used to eat inulin, it was not found that inulin had a special effect on treating diabetes. After investigation, people concerned found that the reactions of long-term use of inulin were "not weak", "not thirsty", "going to the toilet less often at night" and "bright eyes".
Second, the function of digestion and defecation is enhanced, which has a miraculous effect on treating constipation.
Many people who eat inulin obviously feel that their gastrointestinal function has been enhanced and their stools have begun to flow smoothly. At the same time, after taking inulin, it can enhance the peristalsis ability of the intestine, discharge odor, and thus restore the health of the intestine, especially for some habitual constipation and intractable constipation.
Third, the metabolic function is enhanced, and burns and other injured wounds can be quickly recovered.
The metabolic function is enhanced, and the whole body feels warm and energetic. Especially warm hands and feet. Taking inulin on an empty stomach can obviously warm the body within 30 minutes, even in winter. There is also the obvious feeling that the skin becomes smooth after eating inulin continuously, and the acne on the face and the wounds on the body disappear quickly. Inulin has a good effect on dermatitis.
Fourth, skin care.
Beauty Skin provided by Japan Inulin Research Association shows that eating inulin has a good effect on the skin. Mr. Zhongshan, the pioneer of inulin research, once said that inulin can reduce the pigmentation of the skin, whiten and nourish the skin, and make the skin bright, tender and shiny.
People without diabetes drink 50- 100 ml inulin solution every day, and their skin turns white obviously after 3 months. Moreover, the original pigment and spores on the face disappeared cleanly. For example; After eating inulin, Miss Ji Chuan said, "I don't have diabetes, but I feel too fat. In order to be healthy, I began to eat inulin. Inulin has made my skin better. My skin used to be rough, but I still feel rough after washing it with soap and applying skin cream. After eating inulin, the skin has obviously improved. Now I feel smooth and fair, and I feel beautiful without makeup. "
Fifth, get rid of eczema
Dr. Sun Yat-sen's daughter has eczema, which itches badly and she can't sleep well every night. I'm covered in blood. After taking a lot of medicine, the secretion of hormones has been controlled. But other side effects have appeared again. Then I thought of a way to eat inulin. Inulin has the function of cleaning the stomach. Gastrointestinal peristalsis increases, its function of eliminating toxins in the body is enhanced, and eczema disappears.
Sixth, it has special effects on colorectal cancer.
According to American reports, inulin has special effects on the treatment of colorectal cancer. In 2003, there was a special institution in the United States to study inulin. There is a case in Japan in which a patient with advanced cancer recovered quickly after taking inulin.
Seven, improve vascular disorders
Inulin is very effective in improving vascular diseases. There are many reports about inulin reducing blood lipid and cholesterol.
Eight, weight loss effect
Inulin mainly promotes the absorption of vitamins and trace elements by regulating the movement of the stomach, so as to be healthy and energetic, thus promoting the consumption of energy in the body and achieving the purpose of losing weight. On the other hand, after ingesting inulin, blood sugar will drop, but it will not rise, so insulin in the kidney will not be secreted, and glucose will not be stored in cells, so the body will not get fat. On this basis, do some exercise properly and burn some fat to achieve the purpose of slimming.
Nine, protect liver function
The experiment showed that a 69-year-old patient with liver cirrhosis took 10g inulin oligosaccharide every day, and the symptoms of liver coma and constipation were relieved after about 5 days.
X. low or no energy
Inulin oligosaccharide is difficult to be digested or absorbed by human body, and provides little or no energy, so it can play a role in low-energy foods, meet the requirements of people who love desserts and worry about getting fat to the greatest extent, and can also be eaten by diabetics, obese patients and hypoglycemia patients.
Eleven, quickly increase the number of bifidobacteria in the intestine.
Promote the growth of Bifidobacterium in colon by 40 times. Adults ingest 10g inulin oligosaccharide every day, and the number of bifidobacteria per gram of feces increases by 20% after one week. Daily intake of 10g inulin oligosaccharide can reduce the production of toxic fermentation products and harmful bacterial enzymes by 44.6% and 40.9% within 3 weeks.
12. Improvement of skin itching in diabetic patients
According to consumers' feedback, Mr. Sun Yat-sen observed that in Chinese mainland, the use of inulin also led to obvious skin improvement. The pruritus of skin in diabetic patients was obviously improved and disappeared, especially in the elderly and women. The time to eat inulin is about 10 day, which can almost be said to be the miraculous effect of medicine to get rid of the disease, but not everyone has this reaction. At present, there is no systematic, scientific and effective experiment to carry out research and statistics in this field.
