What Are the Main Functions of Food?

The main functions of food are to satiate hunger, provide essential nutrients, and supply energy. Energy is required for many involuntary processes such as growth, household activities, and professional activity. Food also provides the body with the nutrients it needs to maintain its temperature, stay warm, and perform many other functions. Food is a source of energy and supplies this energy through oxidation. The body uses energy from food to power all its processes. Here’s a breakdown of what these functions are.


While we only need trace amounts of vitamins in our diet, they are important for normal growth and development.

This article will discuss what vitamins are, their importance, and how you can increase your intake. Let’s get started!


You must get your daily dose of minerals through food. They support the structure of all bodily tissues and make up 4 percent of your body weight. They aid in digestion, regulate fluid levels, and support proper muscle and nerve function. Some minerals are essential for human health. You can get them from meat, fish, poultry, eggs, and whole unprocessed foods. Listed below are some of the many essential minerals in food. And, remember: minerals can be found in all food sources.


Our body is made up of about 40% to 80% carbohydrates. Although our diets are increasingly high in fats, we still get plenty of carbs from vegetables, fruits, and grains. In fact, carbohydrates are the body’s preferred energy source. Studies show that the brain is sensitive to the glucose levels in the blood. Carbohydrates provide energy and help the body function normally. The average Western diet contains approximately 40 grams of carbohydrates per serving.


While the structure of proteins has long been studied, scientists are only now realizing the role they play in the food industry. This is because the protein structure can have a major impact on the processing of food and its sensory quality. Furthermore, proteins can act as a regulator of gastrointestinal hormones, reducing the amount of calories we take in from a meal. Fortunately, protein-based ingredients are becoming more popular in food processing and manufacturing.
