The recent Public Health England report on sugar reduction recommended that we slash the amount of sugar we eat to just seven teaspoons a day.

Diabetes, cardiovascular disease and obesity have all been linked to high sugar intake. Treating obesity and its consequences alone costs the NHS \\xa35.1m per year.

Jim Al-Khalili invites three scientific experts from different disciplines into the studio to present the evidence behind their strategy to reduce our sugar intake:

- Dr Peter Scarborough, a mathematician from the Nuffield Department of Public Health at Oxford has been analysing sugar taxes\\n- Prof Theresa Marteau, a behavioural psychologist from the University of Cambridge, studies the effects of portion sizes\\n- Jenny Arthur, Director of Innovation and Nutrition at Leatherhead Food Research is experimenting with the microscopic structure of sugar particles
