What is a balanced diet?
Food, in general, is classified into six different categories; protein, carbohydrate, water, vitamins, fats and oils, and minerals. Some have argued that there are seven instead of six classes of food – the 7th class would be fibres.
But whichever way you choose to understand it, the primary point is that it is essential to have all the necessary nutrients in the food you eat. A balanced diet is one that contains each of these classes of food.
Almost everyone is familiar with the five food groups which are: fruits, vegetables, protein, fibres, and dairy; so I wouldn’t waste time explaining those.
But, for the six classes of food, I will explain the different functions they perform in the body, so you understand why you need them in your diet.
Carbohydrate is our primary source of energy. While energy production may be the essential function of carbohydrate, it also acts as structural molecules.
Take for instance; there is a part of the human muscles and liver that contain is the storage form of starch known as glycogen.
For people who think fibres should be classified as a nutrient on their own, fibres are actually a non-digestible form of carbohydrates, and they do not contribute to energy production, rather fibres help the digestive system.
Protein is an essential nutrient because it helps to give your body amino acids that it needs for the creation of specific structures and functions.
What protein does is help with building your muscles boosting your immune system, help to transport molecules in and out of your cells and even create the basis for enzymes and hormones.
Your cells cannot absorb your food protein because these proteins are too large. So your digestive system does the job of breaking them down into single particles of amino acids, which then travels in your body and performs the basic functions they were created to perform.
It goes without saying that water is the most important nutrient of all. While it is possible for humans to live an extended period of time without food, it is impossible to survive without water.
Water performs several functions in the human body; it is needed for so many reactions within your cells.

What set vitamins and minerals apart from the other nutrients is that they do not need to be digested by your body before you begin to benefit from them. These molecules may be small, but they serve a variety of purpose for your tissues and cells.
Calcium is a mineral that your bones and teeth need to be healthy and strong, Potassium performs the duty of regulating your blood pressure, zinc keeps your immune system healthy, and Iron helps to transport oxygen through your blood.
