An appetite for health - research transforming the food we eat

Impact: Economic and/or Commercial, Societal

Description of impact

The UK is in the midst of an obesity epidemic, arising from low activity and easy availability of energy-rich foods. Research conducted by the University of Aberdeen’s Rowett Institute has identified the nutritional effects of protein, including sustainable plant-proteins, on satiety (repleteness), demonstrating that dietary protein is an effective way to control appetite and slow muscle decline. This research has underpinned collaborations with major commercial food brands - Marks & Spencer (M&S), Tate & Lyle, the Jamie Oliver Group – supporting the development of healthier food options, including with M&S Balanced For You range, worth GBP40 million annually. Therefore, economic impact and enhanced understanding of the health benefits of improved protein consumption in the food sector has been achieved.

Outcomes to Date / Future Developments

Research by Prof Johnstone on dietary protein has shown it to be an effective means of managing hunger to achieve weight loss in obese individuals. She has also explored sustainable plant protein sources to promote healthy ageing. Together, these findings support the food industry to develop healthier food ranges, delivering economic impact in the food and drink sector, and enhancing public health and food industry understanding of the health benefits of improved protein consumption.
