It is misleading people because people see the graph and compare it to the graph of rising obesity levels and infer (incorrectly) that if sugar is falling and obesity is rising then it is not sugar that is responsible for obesity.

The truth is that obesity is more complex problem but sugar definitely one of the important drivers.

One way obesity is a complex problem is that in most people it is delayed by decades. Our bodies can take a lot of punishment for a long time before they become disregulated enough to start gaining weight.
