Here is an executive summary of the 2015 dietary guidelines: link
Some of the key brilliance found within:
- Saturated fats (natural) and trans fats (manmade) are treated as equally bad. This defies logic and has been debunked thoroughly.
- Unsaturated vegetable fats (many of which are highly processed) are the recommended fats. This also defies logic.
- Grains, half of which should be "whole grains", yet all of which are highly processed in the modern world, are still being encouraged as a staple. This would be great advice in the old days when a farmer grew wheat and then had it ground locally and made into food soon thereafter. But in todays world of modern grain processing this makes no sense. Grains labelled "whole grains" today are usually refined flours to which they have added back the germ and the bran in proportions unrelated to actual complete grains. Consumers will be hard pressed to know whether they are buying complete grains or reconstituted "whole grains".
- According to the bureaucrats - who would never take the advice of sugar lobbyists - a healthy diet can include up to 10% of total calories as added sugars. That's added sugar, not total! Total carbohydrates would be much higher given the recommendation to drink skim milk, eat lots of fruity things, and load up on pasta and bread.
And we wonder why we have an ongoing obesity epidemic!
The fact is, governments don't do science. Individuals do science. Governments do consensus. Consensus is not science. No one said this better than the late author Michael Crichton (Jurassic Park, Andromeda Strain, etc.):
I regard consensus science as an extremely pernicious development that ought to be stopped cold in its tracks. Historically, the claim of consensus has been the first refuge of scoundrels; it is a way to avoid debate by claiming that the matter is already settled. Whenever you hear the consensus of scientists agrees on something or other, reach for your wallet, because you’re being had.
Let’s be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science, consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.
There is no such thing as consensus science. If it’s consensus, it isn’t science. If it’s science, it isn’t consensus. Period.Crichton was not referring to diet science here but it applies. Governments are always telling us, "the science is settled". They've been saying that about diet since 1977. And yet, obesity rates in the U.S. have skyrocketed since then. The original "Food Pyramid" that helped put the obesity epidemic on steroids in the 1990s is at the top of this page.
What are the odds these same consensus followers are right about any scientific matter?
If only our government would get back to the business of constitutionally limited government and leave the science to the few gifted scientists who can actually prove their theories. We'd all be better off and much healthier.
