To the best of my knowledge in 2013, according to WHO consumption of sugar by adult should not exceed 20 kg /person/year.... that can be translated as near 10 tea spoon a day, however consumption of single soft drink was enough to achieve that.... Later WHO recommended it to be 10 kg per person per year, Now ideally it is said that energy from free sugar should be avoided and it should be 0 kg .
In dental practice, It is necessary to give dietary advice to patients? How many dentist know that? or doing that significantly, needs to be monitored through research.
