What are nutrients?

There are three main types of nutrient that we process in the body: lipids (fats), carbohydrates and proteins.

These three groups of molecules are broken down into sugars, starches, fats and smaller, simpler molecule elements, which we can absorb through the small intestine walls and that then travel in the bloodstream to our muscles and other areas of the body that require energy or to be repaired.

We also need to consume and absorb vitamins and minerals that we can’t synthesise within the body, eg vitamin B12, which are prevalent in meat and fish.
