The Science of Nutrition

Why join the course?

Are we really what we eat? And how do we know what is in our food?

This free online course will look to answer some of these questions, by looking at the science behind nutrition, covering aspects of biology, chemistry and physics. You’ll look at the components of food that are given on food labels and consider how these are processed by the body.

There will be some human biology, focusing on the digestive system, including the liver, and the bloodstream, which carries the processed food components to all parts of the body. You will also find out how much energy different sorts of foods supply.

You will have the opportunity to carry out some experiments to find out a little more about the role that acid plays in digestion and how enzymes work, as well as working out how much energy is contained in a single peanut.

Finally, you’ll consider some of the advice that is given about what constitutes a healthy diet and how overconsumption has led to an obesity epidemic in many countries of the world.
