The analysis traces how different post-Brexit policy strategies would affect the intake, availability, cost and sources of food. Half of all food consumed in the UK is imported, including more than three quarters of all fruits and vegetables. The study shows that, when post-Brexit freedoms over agricultural policy are used to encourage British farmers to grow more fruits, vegetables, beans, pulses and nuts, it could change diets for the better. Our findings highlight the need for health-sensitive trade and agricultural reforms... Protecting people’s health requires consistent policies that don’t shy away from discouraging unhealthy foods and promoting healthy ones.’
