Explore how nutrition and environmental factors influence our health.

On this course you’ll look at the importance of nutrition in human health and explore what happens to the body when it doesn’t receive the right nutrients. You will focus on malnutrition and obesity and how these contribute to the development of diseases, such as diabetes. Using research from the University of Leeds, you’ll learn how food can lead to ill health by carrying pathogens that cause food poisoning, or toxins linked with diseases such as cancer. You’ll then investigate environmental factors, including air pollution and its contribution to cardiovascular diseases.

Skip to 0 minutes and 12 seconds Malnutrition is an important risk factor for human disease. Eating too much or too little can have negative consequences for our body. Food provides us with nutrients which are the building blocks of the body and, therefore, we need to know about those in order to keep our body healthy and prevent disease. The course will be covering a range of risk factors, including nutritional and environmental factors, that can be avoided in order to prevent disease.

Skip to 0 minutes and 44 seconds We’re going to focus on what we sometimes refer to as lifestyle risks, such as smoking and drinking alcohol, but we’ll also look at other environmental agents such as chemicals that may be in the environment, for example, in food and water. You may have seen in the news recently that there’s been quite a focus on health problems related to air pollution, particularly those arising from traffic emissions, so we will look at the reasons why air pollution causes health problems and what those problems are.
