I do not understand how the sources you provided result in the conclusion that 'fats should take higher priority' in a healthy diet. Much of the recent literature suggests that too much fat in the diet can result in a higher concentration of Intramyocellular Lipids (fat in the cells), this has been shown to increase insulin resistance (resulting in +ce instances of type 2 diabetes) [0].
In addition, the blue zone study (largest epidemiological study ever conducted on human health) concluded that diets rich in whole grains, starchy root vegetables, legumes, fruits, nuts and seeds proved to result in the lowest instances of diet related diseases (heart attach, stroke, diabetes, alzheimers) and was found to increase longevity.
"From this There is abundant evidence that increased levels of plasma lipids, predominantly free fatty acids (FFAs) and triglycerides, are causally involved in IR" (insulin resistance)
