Everyone needs food to grow and live. Without it we couldn’t survive. But the way we produce, eat food, and live our lives can have some pretty big effects on our health.
Barely a day goes by without the news reporting a new food claimed to cause or prevent against diseases.
It’s not just you or me as individuals facing health challenges, the whole world is facing them too. People are realising much more that what and how people eat is clearly linked to factors such as poverty and wellbeing. And that as well as social side, there are also environmental impacts to consider.
How can our planet feed 9 billion people by 2050? How do we deal with the fact that it’s not just hunger or obesity that’s the problem, it’s both?
There are scientists working on all of these areas.
Food scientists are responsible for developing safe, nutritious foods that we all take for granted each day. Some work on genetically modifying plants so they grow better and produce more food.
Dietitians help people make informed practical choices about the food they eat and their lifestyle, to keep them healthy. Psychologists look at how different peoples’ behaviours can affect how healthy they are. Biologists look at how the human body changes during lifestyle related diseases like diabetes, obesity and cancer.
