Over the past several decades nutritional advice from doctors and expert researchers has largely relied on one-size-fits-all approach – eat five portions of fruit and veg a day, limit your intake of sugar and salt, stay away from overly fatty or processed foods as much as possible – but in recent times it has become clear that, while this is all good advice, the real-life picture is much more subtle. The latest research has revealed that the way we respond to the food we eat varies widely from person to person.

As part of our four-part miniseries, Future of Food, we’re joined by Prof Sarah Berry, a nutritional scientist based at King’s College London and chef scientist at the ZOE.

She tells us how the gathering of large-scale datasets on dietary habits is changing the way we think about nutritional science, how some of us are more sensitive to the negative effects of certain foods than others, and the key role that advances in technology are playing in the future of dietary research.
