Apparently the WHO published a recommendation that sugar should count for no more than 10% of a healthy diet. This peeved corporations like CocaCola and Pepsico and they're apparently now pressuring congress to stop giving $405 million to help fund the world health organization.
So briefly reviewing some of the scientific literature there is some conflict over what the limit for sugar intake should be.
However having a industry group try to threaten a health organization to get the answer they would prefer is quite reprehenisble. This even violates tenants of capitalism, which require that the producer and consumer be well informed (perhaps perfectly informed, I'm don't quite remember).
