Introduction to Diet, Nutrition and Hydration

Introduction to Diet, Nutrition and Hydration

Learn about nutrition principles, healthy dieting and the significance of keeping hydrated in this free online course.

We do not always find the six vital nutrients required for optimal health in our diet. So how do we ensure the body gets all the nutrients it needs? Learn about the nutritional values of different foods, types of nutrients and the dietary requirements for children and adults. Explore common eating disorders, food-related diseases, the role of nutrition in combating and managing conditions and the impact of malnutrition on the body.


Foods contain different substances, called ‘nutrients’, necessary for the health and growth of the body. We will introduce you to the factors that influence our food choices, the composition of diets and the broad application of nutritional studies. Our bodies need both macro and micronutrients to remain healthy. We will help you understand these components and their respective role in maintaining a healthy and energetic body. Not everyone requires identical amounts, however, and a well-balanced diet provides you with the nutrients your body needs. How can we ensure that we eat a well-balanced diet? We will demonstrate the diverse requirements of expectant mothers, children, teenagers, adults and the elderly. Study how the traditional diet evolved into being relatively balanced despite a lack of knowledge.

Eating disorders adversely affect your body and may lead to physical or mental illnesses and diseases. Explore types of eating disorders, the reasons behind developing them and how you can prevent and cure them. Upon that, you will learn about the diseases of various organs, including the gastrointestinal tract and liver and study the role of nutrition in treating or managing them. The ideal body weight depends upon a person’s height and the risk of developing health-related issues increases when you become either over or underweight. Investigate the factors behind weight gain and loss, ways to manage body weight and lifestyle choices that can aid in maintaining wellness. Tissues and internal organs require fluid to perform physiological functions, such as retaining internal temperature, excreting waste products from the body and providing lubrication to joints. Investigate the significance of staying hydrated, the daily water requirement and the consequences of dehydration for your body.

We designed this course for people who want to maintain good health by making the right nutritional and lifestyle choices. However, it is also helpful for anyone in this industry wanting to improve their knowledge in the field. You don’t need to have any prior learning.
