Nutrition is the study of how nutrients in food are used by the body. The human body uses nutrients to produce energy and perform other functions. In addition, the body also uses nutrients to maintain its health.
A healthy diet includes a variety of foods that provide the body with nutrients it needs. Having a healthy, balanced diet can lower the risk of certain diseases, such as heart disease and cancer. It can also improve sleep and skin quality.
When people aren’t getting enough of the nutrients they need, they can suffer from malnutrition. Nutrition deficiency can lead to chronic disease. Symptoms of malnutrition include weight gain, weakened immune system, fatigue, and depression.
Nutrients are found in every living thing on Earth. They are biomolecules that are essential for the normal functioning of an organism.
There are two types of nutrition: autotrophic and heterotrophic. An autotroph is an organism that uses the materials in its environment to create its own food. Autotrophs include plants, bacteria, and algae. Plants and algae use sunlight to convert carbon dioxide and water into carbohydrates, which are then used by the body to make energy.
An heterotroph is an animal or other organism that doesn’t produce its own food. Heterotrophs can be omnivores or carnivores. Heterotrophs can be divided into two main groups: mixotrophs and euglena. Mixotrophs have a mixture of energy sources, while euglena primarily feeds on inorganic matter.
Carbohydrates are the most common dietary energy source in most populations. The body breaks down carbohydrates into glucose, which it uses for energy.
