Key Nutrients & Their Functions

I am always amazed that many people do not know the function/s that their food items (& nutrients within those food items) play. That said, many aren't too sure what nutrients are derived from those food items that they're eating, despite most being clearly labeled. 

Below is a list of our key nutrients and the main function that they perform. Please click on each for more info.

Protein – repair & growth of tissue (including MUSCLE!).
Carbohydrate – primary energy source.
Fat – secondary energy source.
Vitamins & Minerals – regulate metabolic processes.
Water – transportation of other nutrients.

Key Nutrients - Carbohydrates

In short, carbohydrates are foods that provide you with energy - carbohydrates being your primary energy source. Second being fats and finally protein. Hopefully, breads, cereals, rice, pasta, fruit and vegetables being your main sources of carbohydrates throughout the day.

Broken down through the digestive process, carbohydrates are metabolised into Glucose - some going to fuel brain activity and most of the remainder stored in the liver and muscles as Glycogen.

There are three categories of carbohydrates - Monosaccharides (simple sugars), Disaccharides (dual combination of simple sugars), Polysaccharides (chain of simple sugars, Starches). Simple sugars and starches are commonly referred to as simple carbohydrates and complex carbohydrates respectively. Simple carbohydrates are foods that give a quick increase in blood sugars, complex carbohydrates giving a slow increase in blood sugars. Most food items are now labelled with a ranking system (Glycemic Index) to indentify this.
