Boosting gut health: A comprehensive guide to foods and strategies

The gut is another term for the gastrointestinal tract. The organs that collectively form the gastrointestinal tract include the mouth, stomach, oesophagus, small intestine, and large intestine (which have the rectum and the anus). There are bacteria and microorganisms in your gut that help in the digestion process, they help break down food into nutrients and minerals for the body, these are called the gut microbiome. 

The type of nutrition largely influences the kind of bacteria present in your gut. These gut microbiomes impact your overall health.

Understanding gut health: How your digestive system works

The digestive processes of the body take place in the gastrointestinal tract. The process begins at the mouth, where the food is chewed using saliva, after the food is swallowed, it is pushed into oesphagus. Once the food reaches the oesophagus it is conducted by a special movement called peristalsis. 

Peristalsis is the wave of constriction caused by circular muscles of the gut pushing the food along, the peristalsis causes the food to enter the stomach, which further churns the food using secreted gastric juices. The food stays in the stomach for about three hours and then it is allowed to enter the intestine little by little. 

The small intestine welcomes the chyme (churned food) by mixing it with bile and pancreatic juice to break it into digestible proteins, carbohydrates, and fats with the help of water. After providing essential elements to your body, the food reaches the large intestine, which again breaks into remaining nutrients and discards the waste in the form of faeces that pass into the rectum and are expelled.

Top foods to improve gut health

We learned about the functioning of the gut. Gut health is extremely important for healthy digestion, equivalent to healthy physical and mental health. We all want good health but are there ways to improve gut health? Yes! Your food intake determines your gut health, certain foods can be consumed for a happy and healthy gut.

2. Legumes: Chickpeas, lentils, baked beans, soybeans, kidney beans, and peas are legumes. These contain high levels of fiber and prebiotic fiber. The microorganisms and bacteria in our gut feed on these fibers and break them into essential nutrients.
3. Whole grains: Quinoa, oats, barley, wheat bran, and bulger are a great source of fiber that is required for easy digestion.
4. Nuts and seeds: Yet another storehouse of fiber and polyphenols, nuts and seeds serve the purpose of promoting good gut health. Almonds, walnuts, cashews, chia and sesame seeds, and pistachios can be considered. 
5. Water: Water plays a crucial role in digestion. It helps the intestine break down food and absorb important nutrients, therefore good amount of water should be consumed to ease the process.
