Not sure if I circulated this one before, but here we go anyway. Ok, so it focuses on the old glycemic index and load - but it gives a very elegant exposure-response for inflammatory carb and CHD; also, they have corrected for a host of standard confounders, including the classic risk factor milieu. Paper below:
Note the risk profile based on increasing Carby Glycaemic Load in quintiles going to the rightmost, adjusted fully in model 4 at the bottom:
Now the party piece - note the other so-called risk factors in the table below - like fat, lack of fibre and all the other auld malarkey we have to listen to; again the rightmost is where the people have the highest CHD - notice anything?
Well, it looks like a LCHF peeps' heaven right there: lower saturated fat is worse for CHD, likewise lower Protein, and lower cholesterol. And Lower Alcohol associates with more CHD - hurray! Exercise doesn't figure really. Yawn.
I'll leave you browse the rest....
Yep, it's the carb baby - the higher octane the carby fuel - the more your pipes burn out.
Keys picked the wrong horse - in spectacular fashion ;-)
