Blending Berries could release toxins!

Commented on September 11, 2013

I've been making a lot of smoothies lately and just got a high-powered VitaMix blender known to be able to completely pulverize the seeds and skins in common fruits and veggies.

Now good old Ray Peat has me worried again. I'm not about to stop eating anything with unavoidable seeds, but I know that the seeds and skins of many fruits and veggies contain high concentrations of toxins. What sort of risk do I run from blending the crap out of my seedy fruits and skinny veggies?

possible conservative option: peel any veggies you are worried about beforehand. & throw any seeded berries in last on 'non-pulverize' mode, so the seeds are not ground/broken.

M- I would suggest you focus on quality of life first... longevity merely for its own sake seems more than a bit hollow. I know a number of people who are focused on longevity as a goal in and of itself...they're just take up space / consuming resources. :(

interesting question. we are told by the paleo 'gurus' to avoid seeds & grains (seeds of grasses) & avoid seed/grain oils, but i do not recall reading/seeing anything regarding the seeds on or in berries. & then you have the so called healthy (by some) seed oils, such as blackcurrant seed oil, hemp seed oil, flaxseed/linseed oil, chia seed oil,

Thanks for being constructive thhq. The "best answer" was basically stating that it may or may not be slightly harmful. Most of the others either touted ground berry seeds as super foods or said they might be kind of bad. Hoping for something more concrete. I'm thinking over a lifetime, could these mild toxins add up to a shorter life span? I'm admittedly obsessed with longevity.

You said seeds, I assumed apples and pears, not berries. The subject has been pretty well covered here before.

BTW thhq: read the question before you respond. I'm VERY CLEARLY not blending peach pits. I'm talking about berries. The seeds in berries naturally pass through the body undigested. I'm wondering if breaking apart these seeds, making them digestable, might have adverse effects.

Trolling!?!? What's happening to this website when a perfectly logical query is ridiculed because it steps outside the bounds of "Did caveman eat like X?"??

Not just Ray Peat... It's pretty widely known that most seeds are mildly toxic and many are more toxic. Just a few can be deadly, of course. The seeds don't want to be eaten.

Berry seeds are fairly difficult to grind, even with a primitive mortar and pestle, but I'm unsure how harmful the toxins would be. Generally, the indigenous peoples of North America ate a very widely varied diet (150+ varieties of plants/berries, etc.?), so it's unlikely that they'd consume anything equivalent to a daily morning shake of large modern-day berries. And, if they were eating berries often for periods of time, it'd seem much more likely most of the seeds were eaten and undigested/unsmashed (Even if grinding up the seeds is possible, it seems like quite a bit of work.).

If you're worried, why not eschew ultra-blending and consume a few whole?

Longevity is very fascinating! :-)

Are you eating ground berry seeds daily? Restrictive diets are more worrisome than occasional toxin consumption.

Sure, caveman did not have blenders. Paleolithic peoples were tool users and were more than capable of mashing their food with rounded stones. Would they have mashed up their berries? Doubtful. I happen to love blended berries, but is it healthy?

Oh horrors. Call the food police someone.

Blenders were not paleo and no sensible ancestral person would have eaten fruit seeds and all. Probably not a big deal unless you're grinding cyanide-laden peach pits. Why not core and peel your fruit before you grind it?
