The difference between micronutrients and macronutrients

Plants and humans, including animals, need nutrients to maintain their growth and health. There are two main types of nutrients, called macronutrients and micronutrients, both of which can be obtained from different diets and supplements that are specifically consumed by humans. These include all foods such as grains, vegetables, meat, eggs, fruits, and other eggs in the diet. Although both macronutrients and micronutrients can be obtained from the same source, they differ significantly in various ways. The main difference between macronutrients and micronutrients relates to the amount required to ensure optimal health and its function in the body. More details on the difference between macronutrients and micronutrients are provided below.

The difference between micronutrients and macronutrients

The main characteristics of macronutrients

A large amount of macronutrients are required to ensure the best function of the whole body. For example, carbohydrates constitute macronutrients, and these are usually consumed in large amounts. Carbohydrates are rich in fiber and should be consumed in large amounts to promote human growth. The same applies to meat and fish that contain high levels of protein, so they should be consumed in large amounts. Unlike micronutrients, macronutrients are specifically used to promote growth.

They contain calories that help provide energy to the body. For example, fat, protein, and carbohydrates are all examples of macronutrients, which help provide energy to different parts of the body, such as the kidneys, heart, and brain. This energy is specifically used to ensure that these organs are operating at an optimal level to ensure the best function and quality of the body's health. In order for the body to function normally, it should have enough energy to maintain the functions of different organs, otherwise insufficient energy will cause fatigue. The main food types rich in macronutrients include: meat, grains, potatoes, yams, nuts, fish, water, and oilseeds.

Another noteworthy aspect is that excessive consumption of macronutrients in the form of saturated fat and carbohydrates can lead to health problems such as obesity or diabetes. Since high acid levels may cause excessive consumption of macronutrients, dental problems may also occur. In other words, these should be consumed at a proportional level in order to obtain the best health among different people.

The main characteristics of micronutrients

Unlike macronutrients, micronutrients require small amounts. The main reason for this can be attributed to the source of micronutrients. Micronutrients mainly come from minerals, which are present in small amounts and therefore cannot be consumed in large amounts.

Compared with macronutrients, micronutrients do not contain energy, but they are mainly composed of a large amount of antioxidants. Basically, these antioxidants play a key role in protecting the body from various diseases. They also help to eliminate toxins that may have a negative impact on human health, thereby promoting longevity among them. Most importantly, it can be observed that micronutrients are also crucial in the production of enzymes and other components that help improve different functions of the body. Examples of micronutrients include minerals and vitamins that are usually required in small amounts. Examples of different types of foods rich in micronutrients include: fresh produce, including green vegetables and fruits, iodized foods, and eggs.

Studies have shown that excessive consumption of macronutrients has no effect on health. These are usually present in small amounts, which helps the body eliminate unwanted elements. However, the lack of micronutrients can have a negative impact on health. They can cause fatigue, poor eyesight or mental health problems. If you witness a micronutrient deficiency, you can make suggestions for improving your health. For example, iodine can be recommended to improve thyroid health.

Summary of the main differences between macronutrients and micronutrients

As mentioned above, it can be noted that macronutrients and micronutrients are significantly different due to many factors. For ease of understanding, these are summarized in the following categories.


  • Large amounts of nutrients are required to ensure optimal health and physical performance. These are usually found in large quantities in different types of foods, so they are also needed in large quantities.
  • In contrast, micronutrients are usually needed in small amounts in the human body. They are usually found in small amounts in different types of food.

Body function

  • Macronutrients mainly provide the body with the energy required by different organs to perform various activities. It can also be seen that macronutrients are also responsible for other functions, including the following functions: repair body tissues, store energy in the body through carbohydrates, while fat maintains temperature and vitamin storage, promotes normal cell function and blood coagulation.
  • On the other hand, micronutrients promote muscle growth and improve health by preventing diseases that may attack the human body. Other main functions of micronutrients include: promoting healthy hair growth, promoting good skin, promoting the development of strong teeth and bones, producing hormones, strengthening a strong immune system, and preventing infectious diseases, etc.


  • Examples of macronutrients include: carbohydrates used to store energy, fats used to store vitamins, and proteins responsible for maintaining proper body temperature and maintaining enzyme and acid balance.
  • Examples of micronutrients include vitamins and minerals, which play a key role in promoting the healthy growth of hair, teeth, skin, cells, bones, and the development of a strong immune system that can fight different diseases in the body. In essence, micronutrients are mainly responsible for disease prevention and promotion of quality health.

Health effects

  • Excessive consumption of macronutrients may be harmful to health because it may cause problems such as obesity and diabetes. These significantly affect the normal function of the body, and this situation is not recommended. Lack of sufficient macronutrients in the body can also cause problems such as malnutrition and kwashiorkor.
  • In contrast, there is no data showing the effects of excessive consumption of macronutrients on the body. However, due to insufficient micronutrients in the body, it may cause some health-related problems. For example, scurvy and goiter are two diseases that may be caused by a lack of micronutrients in the body.

In general, a proper balanced diet must be maintained to ensure that the body has sufficient macronutrients and micronutrients to achieve optimal health. If appropriate measures are not taken to ensure that balanced nutrients are always consumed, there is a risk of affecting the body in a negative way.

The table shows the difference between macronutrients and micronutrients

Macronutrients Micronutrients
A lot of need Small amount needed
Provide energy to the body Play a key role in disease prevention
Examples of micronutrients include protein, carbohydrate and fat Examples of micronutrients include minerals and vitamins
Excessive consumption of macronutrients can lead to obesity and diabetes There is no data showing the effects of excessive consumption of micronutrients
Macronutrients mainly come from the following foods: potatoes, grains, fish and nuts, etc. Micronutrients mainly come from vegetables, fruits and eggs

Difference between Micronutrients and Macro-nutrients

Following are the important difference between macronutrients and micronutrients:

Micro-nutrients Macronutrients
Required in very minute quantities. Required in larger quantities.
Prevents diseases. Provides energy.
Consequences of Deficiency
Deficiency results in Anemia, Goiter, Scurvy, etc. Deficiency results in Kwashiorkor, Marasmus, Malnutrition,  etc.
Consequences of Overconsumption
Overconsumption of Vitamins leads to liver and nerve damage. Overconsumption of macro-nutrients results in cardiovascular diseases, diabetes, obesity, etc.
Available in a minute concentration in the body, less than 1 mg/gm. Available in high concentration in the body, equal to 1 mg or 1000 microgram.
Also called trace elements. Also known as major elements.
vitamins, minerals and trace elements. carbohydrate, protein and fats.
Antioxidants, Minerals, and Vitamins are examples of macro-nutrients. Proteins, fibre, carbohydrates, and fats are examples of micro-nutrients.
Are found in fruits, vegetables, eggs, fermented foods, green leafy vegetables, etc. Are found abundantly in cereals, fish, legumes, meat, nuts, oilseeds, potatoes, yam, etc.
Micro-nutrients contribute to body growth and disease prevention. Provides energy required for the metabolic system.

in conclusion

The human body needs nutrients obtained from various diets in order to achieve optimal health. As mentioned above, nutrients are divided into two categories, namely macronutrients and micronutrients. Even if macronutrients and micronutrients are obtained from the same source in some cases, they are significantly different in many ways. The main difference between the two is that the body needs a large amount of macronutrients, while a small amount needs micronutrients. On the other hand, macronutrients are especially used to provide energy and support body growth, while micronutrients are responsible for disease prevention. As mentioned above, excessive consumption of macronutrients can have a negative effect on the body because they can cause health problems such as obesity or diabetes. Insufficient macronutrients can cause health problems such as malnutrition and kwashiorkor. However, there is no data suggesting that excessive consumption of micronutrients can have a negative impact on health. It has been observed that the lack of micronutrients can have a negative impact on health and lead to problems such as scurvy, poor eyesight and weak joints. Efforts should be made to ensure that a good balance is established between the consumption of macronutrients and micronutrients to promote optimal health among different individuals. In most cases, the individual’s diet determines their health.
