Evidence is showing that the HPL may positively influence many in our communities to cut back on the number of sugary drinks they consume. According to a study published in the journal Public Health Nutrition, the health promotion levy led to a 60% reduction in sugary beverage consumption among those surveyed in Soweto. Another study in Langa outside of Cape Town, found adults between 18 and 39 years old reduced their overall sugar intake by over a third after the levy was introduced. Furthermore there have been greater reductions in middle-LSM households than in higher-LSM households.
