Potatoes and cereals are heart disease risk while dairy, fat and meat are good for you


Results: ...The most significant dietary correlate of low CVD risk was high total fat and animal protein consumption. Additional statistical analyses further highlighted citrus fruits, high-fat dairy (cheese) and tree nuts. ... The major correlate of high CVD risk was the proportion of energy from carbohydrates and alcohol, or from potato and cereal carbohydrates.

Conclusion: Our results do not support the association between CVDs and saturated fat, which is still contained in official dietary guidelines. Instead, they agree with data accumulated from recent studies that link CVD risk with the high glycaemic index/load of carbohydrate-based diets. In the absence of any scientific evidence connecting saturated fat with CVDs, these findings show that current dietary recommendations regarding CVDs should be seriously reconsidered.

The first graph published in the paper:

is the most interesting in conjunction with the rest of the results, showing that the high consumption of animal fat and protein correlates very well with high blood cholesterol level and at the same time (see for example Fig.4 and 7) the high cholesterol and high consumption of animal fat and protein correlate consistently and strongly with the low cardiovascular and other diseases' risk! That is yet another nail to the coffin of the cholesterol-heart hypothesis and an indication that the blood cholesterol correlation with cardiovascular disease (+ or -) is secondary and spurious while the primary risk factor appears to be related to the carbohydrate contents of the diet! Note that some of the graphs refer to women some for men but the actual correlation factors are similar for men and momen (see Table 1) with the exception of correlations involving BMI and smoking which are opposite for women and men (that is another interesting subject).

Most of the results point consistently and strongly, see for example Fig.10 towards the carbohydrates contents of the diet as being the strongest positive correlator with the cardiovascular disease risk, where as the animal and most plant fats correlate most negatively (that is being protective) against cardiovascular disease, see Table 1, with the notable exception of sunflower oil which correlates strongly and positively with the CVD.

It is also interestingly to notice a strong linear correlation graph with very low data scatter, between the prevalence of raised blood glucose and consumption of carbohydrates plus alcohol ('CA' variable), on Fig.9:

Although diabetes risk was not directly measured in the study, Fig.9 appears to indicate that diabetes risk may be steeply correlated to the total consumption of carbohydrates plus alcohol, and strongly inversely correlated with the consumption of animal fat and protein (see Table 1). For example an increase of the dietary carbohydrate+alcohol contents from 42% to 68% seems to increase the prevalence of high blood glucose (and thus probably diabetes risk as well) by a factor of 3!

The overall results of this study are also remarkably consistent with the original China Study data as published on the Oxford University web site and  discussed on this blog (see my previous posts).

The study is also discussed in the following journalistic article:
