Nutrition is very important in life due to multiple reasons. As human is makeup of different matters. It contains Water, Oxygen, Hydrogen, Carbon, Nitrogen, Sodium, Potassium, Carbohydrates, Proteins and Lipids etc. Their amount in our body is very important. They must be in balanced for normal body functions. If their balanced is disturbed then they produced many diseases. Amount and place of every micro and macro nutrient is very important. In this article I will discuss some nutritional important and diseases due to the imbalance of these nutrition.
Types of Nutrients in our body:
There are two types of nutrients in our body that are given below:
- Macro Nutrients
- Micro Nutrients
Importance of Macro Nutrients in our body:
Macro Nutrients includes Proteins, Carbohydrates, Lipids etc. They provide energy in our body.
Carbohydrates as a energy source in our body:
Maximum amount of energy is provided by the carbohydrates that can be changed according to the body requirement and conditions of the body. Normally carbohydrates are required 45-60% in our body.
Proteins as a energy source in our body:
After carbohydrates other next macro nutrient that is required in large quantity are proteins. Proteins also provide energy in our body. 1g of protein provide 4 kcals in our body. Proteins are required 20-30% in our body. Amino acids are the building block of the protein in our body. Its means when proteins are broken down into pieces, we get amino acids and vice versa. Proteins are used to build muscles of our body.
Lipids/fats as a energy source in our body:
Next macro nutrient that is required in large quantity is lipids. They provide maximum energy in our body because 1g of lipids provide maximum energy in our body that is 9kcals. Which is 3 times as compared to the energy required from the others macro nutrients like carbohydrates and proteins. They are stored in our body as energy bank. When we need energy but don’t take energy from outside then this energy bank is used to full fill the energy requirement. The amount of energy we intake in the form of carbohydrates, proteins and lipids are used for our body functions including body basic functions and physical activity and the remaining energy is stored in our liver and muscles as lipids. This energy is used in the absence of carbohydrates. Energy can be converted from carbohydrates, proteins into lipids and vice versa. As we know, energy is required for work done in the form of force. As is the case here, for physical activity energy is required for work done. This energy is provided by the macro nutrients in our body.
