Diet funk about to clear?

“It would be all but impossible to carry out a research trial where you controlled the diets of thousands of people over many years. That’s why guidance in the UK is based on a consensus of the evidence available not just on randomised controlled trials.” Victoria Taylor, senior dietitian at the BHF
...the obvious.
There is certainly a strong argument that an overreliance in public health on saturated fat as the main dietary villain for cardiovascular disease has distracted from the risks posed by other nutrients such as carbohydrates. Yet replacing one caricature with another does not feel like a solution.
It's clear that ones diet is designed to be a bit too specific to a person's needs for dietary advice to be generalized beyond a certain point. Whether its their physiological and yes psychological make-up, their preferences according mainly though not wholly to exposure. Environment, culture, region, etc., The best way to get beyond the general advice is to learn to fine tune the interpretation and response to your own hunger and appetite.

General guidelines often seek to minimize risk to those with genetic susceptibilities. It's a bit like weight loss dieting. The insistence on this as the basis of weight regulation and "health" has left those susceptible to virtually all ED's from anorexia to hyperphagia to blunder far too often into these tendencies unwittingly.

So sacrificing minority susceptibility for, in this case, a perceived good isn't necessarily ethical. In this case it's clear that the exact nature of dieting needs to be made abundantly clear. And nor should it be the basis of anything.

When it comes to general dietary guidelines, too many have been seduced by the idea of one perfect diet. It's one thing to diagnose vitamin C deficiency and another to say, there's a diet suitable for all, which everyone should follow.

I suspect this has been invested with the desire to enforce a somewhat imagined bourgeois standard on everyone. On the grounds that this will in itself uplift society.

Finding out how diet affects health isn't particularly amenable to scientific inquiry-way too many variables- I hope this spate of admissions will hold. Recognizing limitations may actually help boffins to identify and make use of what actually is useful.

The aim needs to change too. Instead of trying to control other people, try assisting them with making better use of what comes naturally.
