Even though I think Tim Spector isn't looking the best right now, if that vid was recent, (y'all know I think he needs a good thick steak! The side order of brocolli is optional), (we know he has been getting plenty of plant matter!), I do think about his key message about food quality being essential is essential, these days. When we are talking about his vids and ideas (and books) being good ones to spread around to the general populace/our friends and families, who might be interested in nutrition for life etc, I think it is that essential message we are responding to? That needs to be spoken from the rooftops more. It's a simple but good message. Don't skimp on food quality, if you are weighing up what to spend your resources on! Especially in these inflated inflation times. (Assuming one has the option to weigh up what one spends ones resources on! And that is not a given, even in OECD countries as we know.)
Re the importance of the gut biome - I am of the opinion too, that it is hugely important, and was a missing link for a mighty long time. But why is it only plants that our gut biome feed off? Of course not! In an omnivorous species like us that just doesn't add up. If the humble cow, coming from the not-so humble aurochs, can provide us with every essential vitamin and mineral and lots more besides (thinking of their lovely coats) - why is it left out, not to mention all the other dead critters we thrive on eating, when discussing the healthy gut biome? The healthy human specimen? But left out it consistently is, from my observations. If anyone knows why, apart from for propag... I mean - pro-vegetarian reasons... give me a holler in here! (Wouldn't it be hillarious if you need to eat 30 different plant types to match beef and cow-innards in the nutrition/healthy gut biome department? Which I suspect - could very well be the case.)
