Nutrition Overview
Nutrition is the science of food, the nutrients and other substances, their action, interaction, and balance in relation to health and disease. It is the process of consuming, absorbing, and using nutrients needed by the body for growth, development, and maintenance of life.
Why nutrition is important.
In simple terms food is energy. It is the fuel our body uses to enable us to carry on our daily activities. Some nutrients have energy (calories) and others do not, but both are critical to our bodies. There are over 45 different nutrients that our bodies need every day. Proteins, fats and carbohydrates are the three nutrients that have energy.
The objective of a proper diet is to meet the body’s energy and nutrient requirements, while achieving and maintaining a desirable body composition. The daily requirements for essential nutrients depend on a person’s age, sex, height, weight, metabolic rate and physical activity.
Obesity and related medical conditions are the second leading cause of death in America . Health risks related to obesity include coronary heart disease, hypertension, diabetes, gallstones, osteoarthritis and certain cancers. A basic understanding of nutrition can also help you achieve your personal health, weight and lifestyle goals.
