Until recently, fat consumption and total energy balance have dominated the debate about obesity and health.

However, recent thinking is that sugar should be targeted not only for its calories but as a potential causal agent of disease, i.e. that it is harmful in addition to being fattening. Some research indicates sugar is a prime suspect for causing non-alcoholic fatty liver disease.

More research to determine sugar’s dangers needs to be undertaken, but in the meantime, we need to reconsider consumption levels.
