However, in order for you to have a full gut health understanding we must start from the beginning… the digestive system.

1. Digestive System

Gut health is closely tied to our digestive system, which is a complex network crucial for our well-being. Knowing how it works is key to improving gut health. This part explains where digestion starts, describes the main organs involved, and guides you through the digestion process, including its seven steps.

The digestive system’s job is to turn the food we eat into nutrients that give us energy, help us grow, and repair cells. Important parts of this system include the mouth, esophagus, stomach, small intestine, large intestine, and other organs like the liver, pancreas, and gallbladder.

Where Does Digestion Begin?

Digestion begins in the mouth, where the process of breaking down food kicks off with chewing and the introduction of saliva. This marks the first step of digestion, emphasizing the importance of thoroughly chewing food to aid the rest of the digestive process.

The role of each organ:

  • Mouth. Breaks down food physically through chewing and chemically with saliva, starting the breakdown of starches.
  • Esophagus. Transports chewed food to the stomach.
  • Stomach. Further, it breaks down food using stomach acids, turning it into a semi-liquid substance called chyme.
  • Small Intestine. The most extended part of the digestive system is where most of the nutrients are absorbed into the bloodstream.
  • Large Intestine. Absorbs water and vitamins while converting digested food into stool.
  • Liver, Pancreas, and Gallbladder. These organs produce enzymes and bile to digest fats, neutralize stomach acid, and more.

What are the 7 steps of digestion?

  • Ingestion. The intake of food.
  • Propulsion. Moving food through the digestive tract, starting with swallowing and continuing with the muscular movements of peristalsis.
  • Mechanical Digestion. The physical breakdown of food, such as chewing and the churning in the stomach.
  • Chemical Digestion. The breakdown of food by enzymes and acids in the stomach and small intestine.
  • Absorption. Nutrients from the digested food are absorbed in the small intestine.
  • Secretion. The release of digestive juices is necessary to break down food.
  • Excretion. Removal of indigestible substances from the body as feces.

How Can I Improve My Gut Digestive Health?

Improving your gut digestive health involves a combination of dietary changes, lifestyle modifications, and possibly supplements. Here are practical tips:

  • Eat a diverse range of foods rich in fiber to encourage a healthy digestive system.
  • Stay hydrated by drinking plenty of water.
  • Incorporate probiotics into your diet to support a healthy gut microbiome.
  • Limit foods high in fat and added sugars, which can slow the digestive process.
  • Exercise regularly to help keep food moving through your digestive system.

2. Gut Microbiome

In the quest to understand gut health, the gut microbiome stands out as a critical player. This hidden ecosystem within our bodies is not just a passive resident; it plays an active role in our health, affecting everything from our digestion to our immune system and even our mood.

What is the Gut Microbiome?

The gut microbiome refers to the trillions of microorganisms, including bacteria, viruses, fungi, and other life forms, that reside in our digestive tracts, primarily in the large intestine. These microorganisms are not mere freeloaders; they perform critical functions that our bodies need to function optimally. The composition of one’s gut microbiome is unique, much like a fingerprint, influenced by diet, lifestyle, and even the way we were born.
