No. I think that, in a number of cases, the claims being made are a bit premature. The general principles make sense, but some details are not specifically substantiated by research. I will again give the example of the recommendation on high-fat or low-fat products. I don't think it makes a difference whether Canadians consume low-fat or high-fat dairy products.
As a researcher, my role is to check whether the recommendation that people consume low-fat dairy products is evidence-based. I combed through the literature and did not find any research claiming that it is preferable to consume low-fat yogourt over high-fat yogourt. Other people around the world—I gave the example of the Netherlands—have come to the same conclusion. The same could be said for cheese.
Does science show that low-fat cheese is healthier than high-fat cheese? We don't have the answer, but a recommendation was made to that effect. I feel that the value of scientific data is being stretched in some cases.
