Nutrition is the science that examines the relationship between diet and health, and investigates the metabolic pathways and processes that are used to extract nutrients from food, and convert them into energy and other essential components for our bodies to use. It includes the study of how our bodies respond to dietary intake, and how these changes affect our overall health. Additionally, nutrition also examines how the body processes nutrients, and how certain diseases and medical conditions can be managed through proper nutrition. Nutrition is important to optimal health, and is used to prevent and treat various illnesses and diseases.
Nutritional science examines the relationship between food and the body's ability to absorb and utilize the nutrients it contains. It looks at how different nutrients, such as vitamins, minerals, carbohydrates, fats and proteins, interact with each other and how the body uses them to maintain normal body functions. Nutritionists use this information to create food plans that are tailored to the needs of each individual.
Nutrition also looks at the environmental and social aspects of food, such as the effects of climate change and the availability of food sources in certain regions. In addition, nutritionists may also work to improve the food supply in developing countries and promote nutrition education.
Overall, nutrition is the science that studies the relationship between diet and health, and investigates the metabolic pathways and processes that are used to extract nutrients from food and convert them into energy and other essential components for our bodies to use. It is essential to our physical and mental wellbeing, and is used to prevent and treat various illnesses and diseases.
