First of all, earlier this year, the World Health Organization did talk about taxation, but they actually stated that it is not a cost-effective manner of reducing obesity. They did recommend that countries do it, but they did state that it is not cost effective. We have to be careful interpreting what the World Health Organization did say.
I look at the McKinsey Global Institute report of 2014, which talked about 18 different measures that either government or industry could do to help reduce obesity and disease caused by obesity, which I will also provide to the committee. Taxation was 16th on that list of policy recommendations concerning what governments and industry could do in order to actually move the needle on obesity.
I can refer this committee to the Mexican government's own reports on obesity, as of last year on their website, which I will provide for you, that show that obesity is continuing to rise. I'm not exactly sure what reports are being referred to about Mexico. I am aware of one that was done and written by a proponent of the tax, who actually helped the government design the tax. He pointed to a whopping six-calorie difference in diets since the tax has been introduced. The study did not cross-reference whether those calories are simply being replaced by other high-calorie foods. Six calories is a potato chip.
I have one final comment. When looking at Mexico, it is disingenuous to say that it is only a beverage tax. That tax applies to chips, snacks, cakes, and all kinds of confectionary. It is not just a beverage tax. Even with a broad tax like that, which applies to a variety of products, including beverages, there has been no moving the needle on obesity.
In Canada, our products make up 4% of Canadians' calories currently. That's soft drinks for example, and it's falling. To think that a tax on that small of a segment is going to make a difference is not—
