Prebiotics and probiotics are important for human health 💪

As you may know, prebiotics and probiotics are different from one another, but both play an essential role in human health. It has been known for quite some time that these two nutrients help to maintain the healthy bacteria production in a human’s body and also improve overall health.

The main benefit of prebiotics and probiotics in maintaining a healthy gut is that they also have other benefits such as preventing heart issues, lowering cholesterol, relieve constipation, prevent obesity, prevent cancer etc. Do you know how we can get prebiotics and probiotics? Prebiotics are live bacteria that we can get from different food items. And probiotics are a substance that we can obtain from fiber-rich and carb-containing food.

This article will help you to know the importance of prebiotics and probiotics for human health.

What do probiotics do?

Here are a few benefits of probiotics mentioned below

  • Prevent and treat diarrhea

Probiotics help in preventing diarrhea and decrease its severity.  Antibiotics have many side effects, and diarrhea is one of them. Antibiotics disturb the balance between good bacteria and harmful bacteria.

According to some studies, probiotic use decreases the risk of bacteria-associated diarrhea.

According to reports, it reduced antibiotic-associated diarrhea by 42 percent.

  • Reduce eczema and allergy

Probiotics also help in reducing the severity of eczema in children and infants.

According to a study, infants who use probiotic-supplemented milk have fewer chances of eczema.

Another study was carried out on women who used probiotics during pregnancy. These children are 83 percent less prone to eczema in the first two years of their life. However, there is a need to do some more research.

Probiotics can help in reducing inflammatory responses in children with milk or dairy allergies. We can take probiotics through fermented foods or supplements.

  • Heart health

Probiotics also maintain your heart health by lowering LDL, cholesterol, and blood pressure.

Certain lactic acid-producing bacteria break down the gut’s bile and decrease cholesterol levels.

Bile is a fluid that is made of cholesterol and helps in digestion. Thus probiotics prevent it from reabsorption from the gut.

According to a review of 5 studies, if someone takes probiotic yogurt for 2-8 weeks, it can reduce cholesterol by 4 percent and LDL by 5 percent. Another study found a slight increase in HDL

What do prebiotics do?

The prebiotics help the body in the following way

  • Relieving Constipation

Intestinal dysbiosis is the primary cause of constipation. Prebiotics such as Bifidobacteria help in relieving constipation by stimulating the growth of beneficial bacteria. SCFA production by these bacteria plays a significant role in the modulation of intestinal motility by having a trophic effect on the epithelial cells. This results in increased blood flow in this region and increased intestinal motility as well.

  • Prevention of Obesity

Gut Microbiota causes low-grade inflammation, which disturbs the metabolism of glucose and absorption of fats. These disruptions are the major cause of obesity. Probiotics help improve the gut barrier integrity and reduce intestinal inflammation, thus preventing metabolic alterations and promoting weight loss. Prebiotics cause an increased release of satiety-promoting peptides such as glucagon-like peptide-1 (GLP-1) and peptide YY (PYY) and decreased production of ghrelin, a peptide that promotes the feeling of appetite.

  • Cholesterol-lowering Effects

Prebiotics produce SCFAs which help in lowering the levels of cholesterol in the body. The SCFAs are absorbed in the portal vein and metabolized by life, resulting in lower blood pressure levels. Prebiotics are also involved in the absorption of fats and phospholipids in the lower intestine. Low cholesterol levels in the body increase the clearance of LDL cholesterol and reduce blood pressure levels as well

  • Effects On Immune System

Probiotics help stimulate our immune system. Gut Microorganisms affect our innate and adaptive mucosal Immune system. These effects might be direct or indirect by increasing the population of beneficial microorganisms or probiotics, especially lactic acid. Prebiotics stimulate the activity of Gut Associated Lymphoid tissues which helps in reducing the risk of many severe diseases.

  • Prevention of inflammatory Bowel disease

The dysbiotic intestinal microbiota is the major cause of inflammatory bowel disease; thus, research has been done to discover the treatments that target gut microflora. Probiotics aid in improving gut microflora and prevent Inflammatory Bowel Diseases. Probiotics have also been proven beneficial in Crohn’s disease prevention.


Prebiotics and probiotics are important for gut health and improve your overall health. If you have heart problems, constipation issues, diarrhoea, obesity, or high cholesterol, start taking a sufficient amount of prebiotics and probiotics in your diet. There is plenty of food that is a great source of prebiotics and probiotics. So eat healthily and get a sufficient amount of hot prebiotics and probiotics.
