How long ago was it that science was controverting centuries of populist knowledge that carbs are what made you fat, not eating fat?
Talk about science creating a mind boggling ongoing health crisis by telling people to limit their fat intake and replace it with cereals and bread.
- AstralStorm 9y agoIf by science you mean policy of NHS? Current scientific consensus is that it is caloric surplus - confounded by a bunch of poorly researched factors. For weight gain source does not seem to matter too much. This does not say anything about dietary specifics or how they affect intake and metabolism. Technically nutrition science does not provide strong support for such statements as this carb vs fat one based on interventional studies. Epidemiology alone does not tell you "therefore this change will be beneficial"...
- lmm 9y ago> How long ago was it that science was controverting centuries of populist knowledge that carbs are what made you fat, not eating fat? I've looked into that and all I can say is the history is disputed - some people say there really was a nutritionist consensus, others that this was a popular misunderstanding based on overzealous popularisation of a small number of papers (similar to the myth that the consensus among climate scientists in the '70s predicted an ice age) and that working scientists never thought this. Either way it's a failing of the process, but the appropriate response is quite different; in the first case all we can say is mistakes do happen, in the second we need to get better at ensuring that the real scientific consensus gets translated into appropriate policy actions.
