Fat of the Land?

There seems to be quite a deal of organised resistance to a proposed tax on sugary drinks (http://www.theguardian.com/commentisfree/2015/nov/30/tax-sugary-drinks-poorest-children-childhood-obesity) with manufacturers complaining that it will disproportionately hit the 'poor'. It appears, however, that a high percentage of excess sugar intake comes via this route and the children of the 'poor' are more likely to be classed as obese or overweight when at primary school (so they are already hit). Excess weight is, of course, linked to type 2 diabetes as well as increased risks of heart disease and stroke, meaning (in addition to the personal and family trauma) massive expense to the NHS. The tax could be used to encourage healthier life-styles and might turn people to non-sugar containing alternatives (that, in many cases already exist). I certainly think it is worth trying (accepting that it is unlikely, on its own, to 'cure' the obesity epidemic).
