There was a massive systematic review earlier in the year for dietary causes of heart disease.
I'm surprised we haven't heard more about it...
It seems that there is moderate evidence of association between fish consumption and CHD. (I'd like to see more about all of the correlations if anyone finds any info)
Highly correlated harmful factors are trans fats and high GI food.
So much for tubers not being bad for you. They seem like a great way to get CHD.
The "Seven Deadly Sins"
Grains (wheat/rice/oats etc) . . . . . Dairy (milk/yogurt/butter/cheese etc) . . . . . Nightshades (peppers/tomato/eggplant etc)
Tubers (potato/arrowroot etc) . . . Modernly palatable (cashews/olives etc) . . . Refined foods (salt/sugars etc )
Legumes (soy/beans/peas etc)
