They are the fashionable alternatives to sugar which have been championed by celebrities such as Gwyneth Paltrow and Deliciously Ella.
But agave and maple syrup are not healthier choices, according to a presentation at the British Science Festival, because they are just another form of sugar.
Dietitian Dr Duane Mellor, senior lecturer in human nutrition at Coventry University, has urged people to ignore ‘nutribabble’ and not demonise sugar – which has been dubbed more unhealthy than smoking.
Addressing the trendy syrups like agave and raw cane syrup which are increasingly used as replacement sweeteners, he said they are ‘still sugar’, telling an audience: ‘The bottom line is, sugar is sugar.’
Actress Gwyneth Paltrow, now a lifestyle guru, has credited agave syrup, which is made from the Mexican agave plant, with helping her maintain her slim figure.
