Both macronutrients and micronutrients are used to categorise foods. Water, fibre, lipids, proteins, and carbs are examples of macronutrients. They are really important to our body. Vitamins and minerals are examples of micronutrients.
Our bodies require them in considerably smaller amounts. Macronutrients give the body the energy it needs to survive and thrive. Some of these nutrients are constantly required by the body because they give off continual energy. Because of the nutrient imbalance, people’s health deteriorates. In our bodies, nutrients can both be insufficient and excessive.
There are six main classes of food. They are:
- Carbohydrate
- Protein
- Fats and Oil
- Minerals
- Vitamins
- Water
Carbohydrate
Carbon, hydrogen, and oxygen make up carbohydrates. Carbohydrates can be obtained in Nigeria from various foods, such as yam, maize, sugar, cassava, potatoes, oat, millet, ripe plantains, rice, honey, and bread.
Functions of carbohydrates in the body
Carbohydrates perform many functions in the body, some of which are:
- It generates energy for muscle contraction in one.
- It generates the energy needed by the neurological system.
- It additionally aids in the generation of body heat.
The deficiencies associated with insufficient or excess intake of carbohydrates are Marasmus in Children, lack of energy, reduced functions of the nervous system, etc.

Protein
Hydrogen, oxygen, hydrogen, carbon, and nitrogen make up the majority of protein molecules. This nitrogen is a crucial component of the amino acids that our body needs. It is found in both animal and plant meals.
It comes from various sources, including breadfruit, peas, cereals, oil beans, soybeans, shrimp, snails, chicken, meat, and fish. Some of the deficiencies include Kwashiorkor in children, anemia, etc.
Functions
- To promote growth and development, particularly in children
- To create new tissues
- To replace deteriorated or damaged tissues
- It facilitates the production of hormones and enzymes.
- It provides necessary energy when fats and carbohydrates are scarce or unavailable.
Fats and oil
Oil is liquid, but fat is solid at room temperature because most of the fats in our diet come from plants, while most fats come from animals.
Cream, butter, cod liver oil, beef margarine, vegetable oil, almonds, cheese, palm oil, groundnut oil, and other foods are sources of fats and oils.
Fatty acids and glycerol are the byproducts of the digestion of fats and oils.
Functions of fats and oil
- The body receives heat and energy from fat and oil.
- Fat transports and stores the vitamins A, D, E, and K
- Because fatty foods take longer to digest than carbohydrate-based foods, they help prevent hunger.
- When fat is stored in the body, it helps to prevent heat loss and insulates the body against cold.
- They support and safeguard against damage to body organs like the kidney and the eye.
- They also help the skin’s texture to be smooth.
Vitamins
Another nutrient that is not required in huge amounts but is crucial to our bodily function is vitamin. Thiamine, Riboflavin, Niacin, Pantothenic Acid, Biotin, Pyridoxine, Folic Acid, Cobalamin, Ascorbic Acid, and others are examples of vitamins.
Our immune system depends on vitamins since they help us control and sustain our body’s healthy functions. Almost every product on Earth contains them. Sources of vitamins include carrots, vegetables, fruits, eggs, etc.
Functions
- Encourage growth
- Development of bones and teeth
- Clear sight
- Healthy hair and skin

Functions
- For wholesome growth
- The development of robust bone and teeth
- Necessary for the production of haemoglobin in red blood cells, producing blood haemoglobin, and promoting thyroid gland health.
Water
Water is a vital component of the organism. Oxygen and hydrogen are present.
Direct ingestion, fruits, vegetables, and other foods are some sources.
Function
It is more important for digestion and absorption, controlling body temperature, reproduction, and moving food, oxygen, and other chemical substances throughout the body.
Conclusion
It is important to always have a balanced diet to get the best out of all the food classes. A balanced diet consists of all the six classes of foods in the right proportion.
Too little or excess intake of one class of food can cause some deficiencies and illnesses. It is also important to state that diet greatly influences a person’s appearance and nutritional wellbeing.
Remember that a healthy diet contributes to a long life. You must eat all the nutrients your body needs for it to survive on this harsh planet. You can achieve this by combining and balancing the fundamental components of a healthy diet, such as fat, carbohydrates, water, and others.
