Nutrition is the process by which living organisms obtain food to grow, reproduce, and lead a healthy life. It involves the ingestion, digestion, absorption, and assimilation of solid and liquid material. Nutrients are the components of food that the body needs in adequate amounts to function properly. All types of nutrients have their own functions to perform, but they must work together for the body to stay healthy.
Nutrition can be divided into two main categories: autotrophic and heterotrophic. Autotrophic nutrition is exhibited by plants, algae, and bacteria (cyanobacteria) as they are able to produce their own food from simple substances. Heterotrophic nutrition is the type of nutrition exhibited by animals and humans as they rely on other organisms for their food. A balanced diet is essential for a healthy life as it provides energy for all body activities.
Carbohydrates and fats are known as foods that provide energy, with examples such as potatoes, rice, and other fats. Proteins have great nutritional value and are directly involved in the chemical processes essential for life.
