I've often had quite pronounced allergic reactions to certain apples, but especially if the peel is left on, despite pesticide content - in fact, I have an apple tree in my garden, and despite keeping it clean and well-cared for without the use of any pesticides, and despite taking care to clean everything adequately, I've had reactions to them too.

I found this brief clip of Peat saying that some of the more popular species of apple develop an insecticidal enzyme which can be highly allergenic, but that this might be reduced with cooking, so perhaps I'm unlucky in that I have one of those species. Does it stand to reason that the procyanidin B-2 content would vary significantly between species, and if so - perhaps if one wanted as high a procyanidin B-2 content as possible, it might be fruitful to attempt to discover which species are commonly used for extraction by the supplement manufacturers? I wasn't able to find many papers which explored this, although this one about phenol content of a few apple species might be a useful starting point.

Ray Peat: "[...] besides the starch problem with some fruits such as bananas, you have the allergy problem: and I think that's partly because of the industrialisation of banana-farming, use of a lot of chemicals, and just overuse of the soil stresses the plants - and you've heard of the latex allergy, probably, corresponding to the banana allergy? Both of those, the rubber tree and the banana plant are highly-industrialised, stressed crops, and I think that it's the defensive stress substances that the plants evolved to kill insects which were attacking them. Those highly-cropped species produce this insecticidal enzyme which happens to be highly allergenic to humans. Even some brands of apples have quite a high allergen content, and cooking many of the allergenic fruits makes them safer to eat. [...]"

I think perhaps this isn't news to a lot of people viewing this thread, but I've included it just in case it helps someone make a connection later.

Chocolate is also rich in procyanidin B-2, isn't it? I'm not sure if you'll remember this, but there was a user on RPF who claimed drinking store-bought chocolate milk did a lot to ameliorate his hair loss. I can't remember any further details, but perhaps this is another dot you've connected already?

Why is the native search the way that it is? I can type out parts of a message I have posted, select "Match Any", and it won't come up. I can use a keyword to try to navigate back to a post I saw earlier in the day, but get nothing. Does it simply take a matter of days to update? Longer?

I actually have a number of unpublished emails! I'll have to compile them eventually, but what would be the most helpful way of uploading them? I often see screenshots and things like that; a lot of the context I ask him about is quite personal so I might prefer to abridge them somehow, but I want to provide as much detail as I can in case it helps someone.

Hello! I think some of you might recognise me; it's very nice to see you all, and to be here! I hope I can make a meaningful contribution eventually.

Hello! I was banned too. I'm sorry to re-post these images from Mauritio's thread. This is the only post that I've made which is even remotely close to "backseat moderating" so I've assumed it's the reason I've been expelled.

I suspect that it's possible he didn't very much like me being around anyway, I had an annoying habit of asking questions. This was the last thread I was active in.

@Mauritio Hi, it's great to see you again. I believe I was banned for asking if you were banned. I really didn't think there was anything objectionable in how I asked, but I suppose there was.
