Nutrition is the study of how food influences the body’s health. Food is necessary for survival; it offers critical nutrients and aids in the body’s function and health maintenance. Food contains macronutrients such as protein, carbohydrate, and fat that provide calories to fuel the body and provide energy and play specialized roles in health maintenance. Additionally, food provides micronutrients (vitamins and minerals) and phytochemicals, which do not provide calories but perform many vital functions in the body.

Macronutrients: Protein, Carbohydrates, and Fat


Found in cattle, hog, poultry, game and wild meats, fish and seafood, eggs, soybeans, and other legumes found in traditional Central American cuisine. Amino acids are the building blocks of proteins required for bodily tissue growth, development, repair, and maintenance. Protein gives muscle and bone structure, heals damaged tissues, and aids immune cells in their fight against inflammation and infection.


A carbohydrate’s primary function is to provide energy and fuel the body, just like gasoline fuels an automobile. Sugars or starches found in corn, chayote, beans, plantains, rice, tortilla, potatoes, and other root vegetables such as yucca, bread, and fruit.

Energy enables the body to do daily actions ranging from walking and speaking to running and pushing large objects. Because fuel requires for growth, it is especially critical for developing youngsters and pregnant women. Even when the body is at rest, it requires calories to accomplish essential processes such as regulating body temperature, beating the heart, and digesting food.


Dietary fat, which in oils, coconut, nuts, milk, cheese, meat, chicken, and fish, gives cells structure and protects membranes from harm. Oils and fats are also necessary to absorb fat-soluble vitamins, such as vitamin A, which is necessary for healthy eyes and lungs.

Micronutrients: Vitamins and Minerals Explanation

Vitamins and minerals are food components that contribute to general health and require proper cell metabolism and neurological function.

Vitamins aid in generating energy, wound healing, bone growth, immunity, and the health of the eyes and skin.

Minerals contribute to the cardiovascular health and structural integrity of the skeleton.

Consuming a balanced diet that includes fruits, vegetables, dairy products, protein meals, and whole or enriched grains helps ensure that the body receives adequate nutrients. By illustrating a handful of the roles of specific micronutrients, nutrition education can be made more effective:

  • Vitamin A aids with the vision of the eyes.
  • Calcium and magnesium aid in the relaxation of muscles and blood vessels, hence reducing cramps and hypertension.
  • Vitamin C promotes wound healing and enhances the body’s ability to resist infection.
  • Iron aids in the blood’s oxygen transfer throughout the body and help avoid anemia.

Explanation of the Nutrients as Building Blocks Concept

Protein requires for infants’ growth in utero, child and teenage development, and the repair of injured skin, blood, and other body components in adults who are not developing. Because certain body components, such as blood and skin, are replaced regularly, even adults continually generate new body parts. Calcium is also a necessary component of bone formation. Iron is a component of blood. Due to the short lifespan of blood cells, the body always needs additional iron and protein to produce new blood.
