I'm really on a roll with the "refuting paleo authorities" rants, aren't i? ;-)
Chris Kresser, whom i respected until he got that ol' delusions-of-grandeur disease, has one of his podcasts freshly out -- you know, those ego-massaging audio shows, which begin with WHAT HE ATE FOR BREAKFAST, as if the world hangs breathless, waiting for that august pronouncement....
He, along with Mark, is distinctly pro-veggie because they're so HEAAALTHY (tra-la-la). He offered three reasons we should all be stuffing our faces with them, so i of course need to offer you three more, proposing that his opinion is a total CROCK [evil grin].
Vegetables (we'll leave fruits in the cellar waiting for their turn at castigation) are full of ANTIOXIDANTS, and OMG, those things are just fabulously spectacularly HEALTHY ... for the plant. Oh wait -- you mean they don't work AS antioxidants when we eat them???
No, that doesn't seem to be their function. It SEEMS that they act like OXIDATING agents and that in THIS case that's a good thing! Because (tongue in cheek here) our own bodies don't make enough oxidants we NEED vegetables to perform this sometimes-toxic operation, so that it prompts our systems to churn out more antioxidants of their own!
Suppose we already have trouble generating enough endogenous (the actually effective kind) antioxidants for our basic needs? So we eat vegetables that require we produce more than before ... kinda sounds stress-causing to me. As a matter of fact, this sounds very much like the argument that claims low-carbing makes you hypothyroid, because in a healthy person adding carbs requires that the body produce more hormone to metabolize it. And the enemy of my enemy is my friend....
Well, if you discount the antioxidants-which-don't-reduce, how 'bout them PHYTONUTRIENTS!!!
Name me one essential phytonutrient. Lycopene? A carotenoid which has been found of use in certain illnesses -- I SEE! This is an argument for Manifest Destiny as well as Intelligent Design because Sky Daddy gave us a disease which we couldn't cure till we learned how to make pizza sauce!!! He wanted us to discover America, and learn that tomatoes aren't toxic, and make sure they found their way to Italy, and set the chefs to work revolutionizing a peasant bread dish, and ....
OH, you mean a MEDICINAL plant -- we ain't talkin' about HERBS today! Do you have foxglove with your dinner? I have absolutely no problem with plants-as-medicine. I'm talking about "eat real food, mostly plants."
How about RESVERATROL! What, did you say you can't get significant quantities from "eat real food" -- that you have to concentrate it significantly to show benefit? AND you say that the benefit from drinking red wine actually comes from the ALCOHOL? (hehehe) Well, who'd 'a' thunk it....
Sorry, Chrissy, when you have concentrate plant "nutrients" to get benefits from them, then we're talking about drugs again.
Don't skip that paleo-requirement, of canonizing KAAAAALE -- "it's all about the kale"! Just THINK about how filling and how full of wonderful minerals kale is! ...FILLING.... Back in the '80s I tried a super-low-fat diet, filling up on vegetables and lean meat -- big problem there was that my stomach may have been "full" but my appetite certainly wasn't satisfied. That may be the problem with LFers grazing -- you're full but still hungry on a nutrient level, so as soon as there's room in your stomach you go searching for something to eat that might actually make you feel FED. Rinse and repeat.
And just think of the fact that kale is also not only full of ANTInutrients (so doesn't do a damned bit of good to eat it raw in a salad or ground up in a smoothie), it's also one of a huge family of GOITROGENS.
So are sweet potatoes and brussels sprouts and sauerkraut and broccoli and cauliflower and ....
Do i have to also list the high-FODMAP vegetables which the Veg Squad so love?
Don't get me wrong -- if YOU like vegetables and they agree with your system, by all means chow down! I and many other people like me have problems with them, and they are by no stretch of the imagination something we should TRY to consume more of!
It's just another damn case of "it suits me so you have to do it too" that has become so rife in the nutritional world.
