My grandpa was a Great Depression child. I remember my mom would have to dig through his pantry and throw out the expired food every time we visited, that man would throw nothing usable away ever.

I eat the entire apple. Learned to do it so I simultaneously wouldnt litter on hikes and also wouldn't have to carry a slimy apple core in my backpack. Then i got used to it and started doing it all the time. Why not? Free apple.

Also, the girls like a horse boy.... ifyouknowwhatimean

Litter...food that literally grows on trees?

FWIW, m6 grandpa taught me to easy the whole apple top to bottom to help the core's fibrous bits break apart easier. 🤩🤘🏼

That seems overly strict. I assume you're not eating apple after apple for the amygdalin to do any harm, but then I also don't assume you're eating apple after apple for you to do any harm by just chucking it (without the sticker) somewhere out-of-the-way. I eat so closely to the core that people think it's weird, but the core itself is physically uncomfortable to eat.

I haven't tested it, but by now you should have built up an immunity to poison since apple seeds contain small amounts of cyanide. Or maybe it was arsenic. One of those... I'd have to look it up. But now you don't have to worry about someone poisoning you.

You can't get immune to cyanide ever

But iocane powder on the other hand...

Corpses are immune.

Pretty sure arsenic will build up in your system over time though

If you eat it from the bottom up, the core isn’t that bad in terms of texture. As long as you spit out the seeds, it’s all edible.

You can eat the seeds as well. Just uncomfortable, not unsafe. There isn't enough "cyanide" inside 1 apples seeds. You'd need to eat on the absolute lowest estimate, 10-20+kg of apples and grind up, not chew, the seeds to get enough chemicals to create enough cyanide for a poisoning.

Haha I just mentioned this in another comment. It's like one of my favorite little food factoids. My daughter who is still just 3 has always eaten the whole apple, and it always made my wife worry she was going to die. I'm like nah she'll be fine.

Is it true that you build up an immunity to cyanide by eating the seeds, or is that just an old wives tale kind of thing?

You cannot build up an immunity to cyanide. The mechanism of action for it to act as a poison is that it directly limits aerobic respiration on a molecular level. To put that more simply, it stops oxygen from getting where it needs to go and effectively stops your cells from "breathing", ultimately stopping your mitochondria from functioning. To put that in a more complex way, it binds to part of an enzyme called cytochrome c oxidase that is essential to ATP synthethis and prevents the reaction from occurring.

Horrifyingly, cyanide poisoning cannot be fixed by simply giving the body higher concentrations of oxygen to breathe in. It doesn't prevent your repository system from uptaking oxygen. Instead it prevents your individual cells from using the available oxygen.

While it is sort of technically possible in the case of cyanide for the liver to produce more rhodanese (an enzyme that specifically reduces the toxic effects of cyanide in the body) the reaction is dependent on sulfur. Perhaps if you ate foods like eggs in very large quantities and also regularly ate larger amounts of cyanide you could maintain a state of immunity to doses larger than what would normally kill a person but I can't find any evidence of someone stupid enough to test that. Regardless this immunity is in the form of getting your liver to simply clear the cyanide from your system faster and does nothing to stop the underlying cellular asphyxiation.

As an aside Arsenic which was also mentioned earlier interrupts mitochondrial function as well, but in this case it takes the place of Phosphorus (The P in ATP) and the resulting molecule is not able to react correctly. While not a perfect comparison you can think of cyanide as starving your cells of oxygen while arsenic starves them of useful fuel. Neither of these are something you can build an immunity to.

Sadly i don't know about the immunity part. While i have dug through the depths of the internet to find out how many and which sort of seeds are required for lethal dose and even then the estimate range is huge, lovest end 10-20kg up to 100kg worth of apples and no mention of which sort. I haven't looked into the immunity part.

In addition the seeds need to be ground up, chewing might not even be enough to break up the seeds well enough for the digestive system. Otherwise those will pass through fully intact.

Thats an old wives tale methinks. The amount ingested via apple seeds is so small that it is unlikely to generate enough response for immunologic or epigenetic adaptations to be unaffected. Even if it does result reduce effects in any sense it would likely be overwhelmed in any purposeful poisoning.

I saw an old guy eat the entire apple in 2018. Weirdest dam thing I’ve ever seen.
