I've gone off Spector and the whole Zoe thing. I was very engaged with it during the Covid tracking and quite interested in the gut biota / diet initiative, but it's become increasingly like a cult. Zoe's all high-pressure selling and Spector's gone off the rails, imo.
I watched a couple of his recent videos last week. He was bullshitting. Enthusing all over the place about 'science' where the actual science doesn't back his statements, and misdirecting the scientists he interviewed so they never got to make their actual points. He only seems to like interviewees who reflect his bouncy, boyish, bullshit energy.
It happens. Again during the beginning of Covid, I was a big fan of John Campbell. He started off analysing the available data in sensible ways, maybe a little facile at times but basically solid and made things easy for people to understand. Then he went all anti-vax conspiracy theorist, getting more absurd as his YouTube revenues increased. I suppose it's unrealistic to expect people not to follow the money, even if it leads them on to treacherous ground.
Anyway: I'm a nutrition bore and no, I'm not fretting about UPFs. I make the vast majority of my food at home - and I use "scary" ingredients like flour improvers (wheat gluten, ascorbic acid), different sugars, citric acid, MSG and xanthan gum, plus anything else I think will get the desired result. I actually prefer supermarket multigrain bread to my own and, if I had the right machinery, would happily pump carbon dioxide through my dough to get an even crumb!
Practically all food is processed. Processing our food is what enabled humans to evolve and to develop communities that could sustain population growth. "Ultra" processing suggests a loss of nutrition: that is true of some things you already know are nutritionally impoverished, like cheese string. But what the hell's supposed to be wrong with pizza??
Here's the ingredients list for ready-salted crisps: Potatoes, Vegetable Oils (Sunflower, Rapeseed, in varying proportions), Salt, Antioxidants (Rosemary Extract, Ascorbic Acid, Tocopherol Rich Extract, Citric Acid).
Not evil. (Ascorbic acid = Vitamin C; Tocopherol = Vitamin E)
I love 'em!
