Healthy and varied food is very important for our digestion. Nutrients are absorbed from this diet and converted into energy and building materials for the body. Due to an unhealthy lifestyle, digestion can be out of balance. The powerful herbs in our products help to restore this.

Digestion and metabolism: Everything you need to know about metabolism

Our digestive system plays a crucial role in how our body functions, from converting food into essential nutrients to maintaining a healthy metabolism. On this page we dive deep into the complex world of digestion and the many components involved in this vital process. Read on to unlock your body's secrets and discover how you can improve your health through a better understanding of your digestive system.

What is Digestion?

Digestion is the process of breaking down food into nutrients that can be absorbed by the body into the blood. This complex process begins as soon as food enters your mouth and ends when waste products leave the body through the anus. The digestive process involves several organs, including the esophagus, stomach, small intestine, colon and rectum, liver, and more.

How does digestion begin?

Digestion begins in the mouth where chewing and saliva begin to digest the food. Saliva contains enzymes that start breaking down carbohydrates. Proper chewing is essential as it helps to mix food with digestive juices and break it into smaller, more manageable pieces.

What happens in the esophagus?

After swallowing, the food moves through the esophagus to the stomach. The muscles in the esophageal wall help push the food along in a journey that usually takes only a few seconds. During this phase, the correct functioning of the sphincter between the esophagus and the stomach is crucial to prevent reflux of stomach acid and stomach contents.

The role of the stomach in digestion

In the stomach, food is mixed with gastric juice, which contains hydrochloric acid and enzymes that break down proteins. The lining of the stomach contracts to grind the food and slowly send it to the small intestine. This process can vary from 1 to several hours, depending on the composition and quantity of the food consumed.

How does the small intestine function?

The small intestine begins with the duodenum, where most of the chemical digestion takes place. Once the food reaches the duodenum, enzymes from the pancreas and bile from the gallbladder are added to further break down fats, proteins and carbohydrates. This initial section at the beginning of the small intestine is crucial for preparing the nutrients for absorption later in the small intestine. The duodenum also plays a role in neutralizing the acidic food coming from the stomach, which is essential for the effective functioning of digestive enzymes.

The small intestine is where most of the nutrients are absorbed. Once food reaches the small intestine, enzymes from the pancreas and bile from the gallbladder work together to break down fats, proteins and carbohydrates. The small intestine has a very large surface area due to the presence of villi, small protrusions that aid in the absorption of nutrients.

The importance of metabolism in the digestive process

In addition to digestion, metabolism also plays a vital role in our health. Metabolism includes all chemical processes that take place in our body that ensure that the absorbed nutrients are converted into energy and building blocks for the body. These processes are divided into two categories: anabolism, where energy is used to build cells, and catabolism, where nutrients are broken down and thus begin converting into energy. These metabolic activities are essential for maintaining vital functions, regulating hormones, and supporting the immune system.

What does the large intestine do?

In the large intestine, water is extracted from the indigestible food and the remaining materials are converted into feces. This process is essential for maintaining water balance in the body. Bacteria in the large intestine also play a role in the further breakdown of certain materials, producing important vitamins such as vitamin K.

The meaning of liver and gallbladder

The liver plays a crucial role in digestion by producing bile, which is essential for the digestion of fats. The gallbladder stores this bile and releases it into the small intestine. The liver also processes nutrients that are absorbed from the intestine through the portal vein.

The influence of pancreatic enzymes

The pancreas produces digestive enzymes that play a crucial role in breaking down proteins, fats and carbohydrates in the small intestine. These enzymes ensure that nutrients are broken down into molecules that are small enough to be absorbed through the intestinal wall and transported in the blood.

Digestion of fats and proteins

Fats and proteins require special attention during digestion. Enzymes specific to the breakdown of these macronutrients work in the stomach and small intestine to produce fatty acids and amino acids, which can then be used by the body as building blocks or as energy sources.

The role of glucose in digestion and energy supply

Glucose, broken down from carbohydrates during digestion, is important for our body. It functions not only as a primary energy source for cells but also as a foundation for important metabolic processes. After absorption through the intestinal wall, glucose circulates through the body via the blood. Insulin, produced by the pancreas, regulates the uptake of glucose into the cells, supporting health and energy levels. This makes glucose essential for both our daily functions and overall metabolic balance.

The total duration of the digestive process

The total duration of our digestion varies, but it takes 24 to 48 hours from the time food is consumed to the time the remains leave the body as feces. However, this time frame depends on several factors, including the type and amount of food consumed, the efficiency of digestion, and the overall health of the digestive system.

Here's how this process typically unfolds:

Mouth to stomach: Chewing and swallowing food takes only a few minutes.
Stomach: Food can stay in the stomach for between 2 and 4 hours, depending on the composition and complexity of the meal.
Small Intestine: Food stays here for about 4 to 6 hours, where most of the nutrients are absorbed.
Colon: The remaining contents can remain in the colon for up to 24 hours or longer. Here water is absorbed and feces are formed.
Rectum: The final stage of digestion, where stool is temporarily stored before leaving the body, usually lasts several hours until the next bowel movement.

These time periods may vary depending on individual digestive health and other factors such as age, metabolism and lifestyle.

How can you support your digestion?

  • Eat a balanced diet rich in fiber: Fiber aids the movement of food through the digestive system and supports healthy intestinal flora.
  • Drink plenty of water: Hydration is crucial for good digestion because it helps in the formation of digestive juices and the passage of food through the intestines.
  • Limit high-fat and heavy foods: Too much fat can slow digestion and lead to discomfort.
  • Exercise regularly: Physical activity stimulates bowel movements, which helps regulate digestion.
  • Add ginger to your diet: Ginger is known for its ability to support digestion. Consider drinking ginger tea or adding fresh ginger to your meals.
  • Consider digestive enzymes: For additional support, we offer a range of digestive enzymes in our range that can help break down food efficiently and improve nutritional absorption. These can be particularly useful for meals that are heavier or contain more fat.
