Why FITPROs find the digestive system hard to revise

The Digestive system is notoriously claimed to be one of the hardest modules within the Level 3 Nutrition exam syllabus, so you are not alone if you find this area difficult to understand or remember.

Unlike other areas of anatomy (like muscles), we never get to see our intestines or stomach, which makes it feel theoretical. It may also feel like this is less directly related to training clients and giving advice as a FITPRO..

Although you might not actually be quoting the parts of the digestive system and how we pass food, with your clients. The knowledge of this is foundational and absolutely crucial in order to understand the deeper nutritional advice we give our clients.

Understanding The Passage of Food

To help you remember the Passage of Food, we use a story acronym about a DJ in Los Angeles.

For a moment imagine Kate Moss is now a DJ and she is doing her DJ thing in LA.

Now the acronym that goes with this is MOSS DJ I LA

(aka Moss is a DJ In LA)

So let’s break down what this means:

M = MOUTH

The mouth starts the digestive process, with mechanical digestion via the teeth and tongue. Chemical digestion also starts here in the mouth, with Amylase (inside saliva) breaking down simple sugars.

O = OESOPHAGUS

This is a tube that connects the mouth to the stomach, and allows food to move in just one direction. A mechanism called peristalsis assists in ensuring the food moves down the oesophagus.

S = STOMACH

The stomach is like a carrier bag where food can be stored for 2-4 hours before moving onto the small intestine. The main role is to kill bacteria using hydrochloric acid, and the digestion of Proteins via and enzyme called Pepsin.

Then the mushed up food (called Chyme) leaves the stomach in small amounts (approx 1 tsp per minute) via the pyloric sphincter.

S = SMALL INTESTINE

The small intestine is a key area for both digestion and absorption. This is broken into three areas: The duodenum, jejunum and ileum

D = DUODENUM

This first section of the small intestine is all about breaking food down, especially carbs, fats, and proteins. This is when key enzymes like lipase are secreted from the liver and pancreas to help breakdown the macronutrients,

J = JEJUNUM

Finally, the food can be absorbed into the bloodstream. This area of the small intestine is lined with micro-villi , which are small hair-like finger protrusions. Their role is to increase the surface area and maximise absorption

I = ILEUM

Much like the Jejunum this is another site of absorption of key macronutrients. After absorption the carbohydrates become glucose when floating in the blood, and glycogen when stored. Protein becomes Amino Acids after absorption, and fats become fatty acids and triglycerides.

L = LARGE INTESTINE

The large intestine is where the waste products, that can’t be absorbed, are compacted together for easy excretion. This is the point that water and micronutrients are absorbed into the bloodstream

A = ANUS

The anus is the exit valve whereby waste faeces is excreted into the toilet. This concludes the end of the passage of food
