The large intestine is the largest immune organ of the human body. 60%-70% of the immune cells in the human body are produced by the large intestine. Therefore, maintaining the healthy environment of the large intestine helps improve the body's immunity.
Prebiotics are fermented by coliform bacteria in the body to produce organic acids, lower the pH of the intestinal environment, improve the growth environment for bifidobacteria, lactic acid bacteria, etc., promote the balance of the flora, maintain the environment in the large intestine, and improve the body's immunity.
Galactooligosaccharide (GOS) is a non-artificial oligosaccharide derived from animal milk. In nature, there are traces of galacto-oligosaccharides in animal milk, while human breast milk contains more, it has the general characteristics of oligosaccharides, has good bifidobacteria proliferation activity, and is a high-quality prebiotic. Among the three internationally recognized prebiotics, galactooligosaccharide is the only oligosaccharide that exists in breast milk and can be used by the eight beneficial bacteria in the human intestine at the same time, and is known as the "golden prebiotic."
1. Enhance human intestinal immunity
Since galactooligosaccharides are not digested and absorbed in the human
gastrointestinal tract, they enter the large intestine directly and are used by
bifidobacteria. Bifidobacterium, Lactobacillus and other bacteria constitute the
membrane flora of the intestinal flora. Membrane flora protects the intestinal
mucosa and lymph nodes by producing bacteriocins, organic acids, hydrogen
peroxide and other substances to prevent or inhibit pathogenic bacteria from
invading intestinal mucosa and lymph nodes. The intestinal flora acts as an
antigen stimulus to promote the development and functional maturity of the
immune system, the toxic products produced by the intestinal flora have
broad-spectrum immunogenicity, which stimulates the immune system and enables
the body to gain resistance to many pathogenic bacteria and their toxic
products.
Galactooligosaccharide can promote the peristalsis of the human intestinal tract and enhance the ability of the intestinal tract to promote movement, so that harmful substances can be discharged from the body in time. First of all, galactooligosaccharide can be used as a high-efficiency nutrient for beneficial bacteria such as bifidobacteria, so that the beneficial bacteria such as bifidobacteria in the human intestine can rapidly multiply, rebuild and restore the intestinal microecological balance, and improve intestinal function; Secondly, bifidobacteria fermented galactooligosaccharides to produce short-chain fatty acids such as acetic acid and lactic acid (pH is about 5.0), which promotes intestinal peristalsis and enhances the ability of intestinal propulsion; In addition, galactooligosaccharides have strong water absorption, which can increase the water content in the stool and make it easy to be excreted from the body.
3. To prevent dental cariesGalactooligosaccharide has the characteristics of not being digested and absorbed by the human body, low in sweetness, and low in calories. It is not used by streptococcus in the oral cavity, nor is it decomposed by oral enzymes. So it has the function of preventing dental caries.
4, the effect of galactooligosaccharides on cardiovascular health
The intestine is
the human body's largest "toxin-carrying organ" and the largest
detoxification organ. If toxins cannot be eliminated in time, they will be
reabsorbed in the colon and enter the bloodstream, endangering human health.
The acidic environment in the intestinal tract formed by
galactooligosaccharides will promote intestinal peristalsis and the excretion
of harmful substances in the intestine. It can not only inhibit harmful
bacteria and reduce the production of toxins by increasing the number of
beneficial bacteria, but also use its own water retention properties to prevent
constipation, and it can form a barrier on the intestinal wall to prevent
toxins from being absorbed into the blood. So as to maintain cardiovascular
health.
Galactooligosaccharide
is not only a prebiotic, but also a kind of dietary fiber. The mechanism that
dietary fiber helps to control weight is inferred from the following studies: Fiber
replaces the energy and nutrients available in the diet; Fiber increases
chewing action, which can limit food intake and promote the secretion of saliva
and gastric juice, thereby causing stomach distension and increasing satiety; Fiber
reduces the absorption efficiency of the small intestine, and
galactooligosaccharide as a dietary fiber can affect energy intake.
