glad that was cleared upThe Independent has decideed that "food manufacturers that market American-style mega-meals and jumbo portions are to blame for Britain's obesity epidemic, a conference was told yesterday." Andrew Stuttaford thrashes the piece: "Research in the US has shown that in the past 20 years the size of a standard hamburger has increased by 112 per cent and bagels by 195 per cent. Pasta servings are 480 per cent bigger and cookies 700 per cent larger."Isn't it a well known fact that every time the Food Pyramid gets redone that "suggested serving sizes" are also scaled down? It isn't the case that Cookies are 700 per cent larger, but the "suggested serving size" of a cookie has shrunk. The value of the numerator can remain constant, yet when the denominator decreases, the value of the fraction changes. |
