Good Digestion and Absorption of Nutrients

nutrient-absorption1Although good nutrition starts with a healthy diet, good digestion and absorption of nutrients are the essential next steps.

Here’s how good digestion and absorption of nutrients into your bloodstream works.

Eating good food is vital. But the food you eat can’t nourish your body until it’s in a form your body can use. Good digestion changes the food you eat into tiny molecules for nutrients absorption into your bloodstream.

Your blood can then carry nourishment to all the cells of your body.

With good food, good digestion and absorption of nutrients and good blood circulation, you’ll be able to build and nourish all your cells that provide you with energy. These are necessary steps for cellular nutrition.

Healthy Digestion and Absorption of Nutrients

The saying “You are what you eat” really should be “You are what you eat and absorb;” because nutrient absorption is essential to good health.

Your digestive system is made of a series of hollow organs strung together by a long twisting tube that goes from mouth to anus. Mucus membrane linings in your mouth, stomach and small intestines have tiny glands that produce digestive juices to break down your food.

Good digestion starts in your mouth and digestion absorption in the small intestines completes the absorption of nutrients into your blood.

But for carbohydrates, proteins, fats and liquids to be absorbed into your cells, they must first be turned into much smaller molecules. The carbohydrate digestion begins in your mouth, protein digestion begins in your stomach and digestion fats begins in your intestines.

Most digested nutrients, like simple sugars, amino acids, vitamins, minerals, phytonutrients and water must to pass through your intestinal walls into your bloodstream to be carried to your cells.

Your liver, pancreas and nerves all play roles in a healthy digestive system and the absorption of nutrients. Once your food is broken down into simple components, you’re ready for nutrients absorption.

This takes place in your ileum, which is part of your small intestine.


The inner walls of your ileum are covered with thousands of minuscule finger-like structures that are called villi. Some of the digested food passes through the thin walls of the villi into tiny blood vessels.

But digested fats and fat-soluble nutrients take a less direct rout through special lymphatic vessels before moving into your bloodstream.

Digestion Absorption of Nutrients into the Blood

With good digestion, the muscles in the walls of your esophagus, your stomach and your intestines all work to mix and push food and fluids through your digestive system. This action is called peristalsis.

Peristalsis works like ocean waves processing food for good digestion.
Once good food, fluids and digestive juices mix, your stomach slowly empties it all into your small intestine for further food digestion.

Finally, all the good nutrients are absorbed through intestinal walls to flow to your cells in good blood circulation for good cellular nutrition.

With a super healthy diet (including some raw food), moderate exercise and never overating at any meal, you should be able to maintain good digestion and won’t have to be absorbed with digestion absorption. :-)

So how’s your digestive system working? Has it gotten better or worse? If worse, what are your symptoms? If better, what’s working for you?
