Yes, I heard that during the day yesterday, and found it very interesting. The main thrust of the program is that sugar and refined carbs are the enemy of the heart, and not fat. And that we've been misled over the years by vested interested and biased/shoddy research. It was claimed that some animal fats, such as dairy, have a protective effect on the heart.
It was impossible to analyse the evidence that they were presenting, without having access to the actual evidence, and I'm not sure how much of it to believe. I can easily accept that unrefined vegetable oils might be healthy, and that eating unprocessed white and red meat can be healthy. But when it comes to processed meats, such as turkey twizzlers, sausages and cheap deep-fried burgers, I tend to believe that those really aren't a healthy option! But perhaps I'm just biased, because of years of indoctrination?
Also, I think that e.g. chips from a chip shop aren't a healthy option, because the fat has been used for so long and so it's full of toxins. I think the issues may be related to how food is prepared and cooked. My personal opinion is that we should feel fairly safe eating fresh whole foods, prepared and cooked in a traditional manner. And the more vegetables the better. It also seems sensible to eat minimal refined carbs or sugar.
The issues explored in the program have parallels to the world of ME; Vested interests carrying out biased and shoddy studies which (for various reasons) governments, vested interests and some industries buy into, and the public get carried along with the prevailing wind.
