I really doubt it was the "similarity to meat" that gave you those symptoms (though obviously there is no way for me to verify that, so you have the last word on what happens in your own body). Anyway - there is a great comment that I saved (https://www.facebook.com/david.zilber/posts/pfbid02CkCY53qDdzpUFYmSzc9gfvsTpHHwvw1Y1prDhKT1ErNZuUdYMSifSZGJoEEiYkKbl https://www.facebook.com/david.zilber/posts/pfbid02CkCY53qDd...) "Here’s a pesky little chemical called hexanal. If you’ve ever eaten a beyond burger, or any of these plant based products 2.0 (though to be honest, it’s more like they’re on V.46.6.2) and burped 10 or 15 minutes afterwards, and thought to yourself, “Hmmm, wow, ok I definitely just had a meat alternative” you were probably regurgitating this aerosol. Some people think it’s fruity, like green apple, others like mulched grass. At the lab, we had to walk outside to get wafts of it in its pure form, but the minute I opened the cap I knew exactly what this flavour was…. “OLD FRYER OIL, 100%”. It’s metabolized in all manners of organisms through the oxidation of fatty acids, and is… kind of unpleasant?! The point is that while this molecule exists in fava beans, peas, and soy, (the three kings of texturized vegetable protein) when you have a WHOLE FOOD, its there in harmony among all sorts of other volatile compounds, while also being locked away deep inside the beans fibres. It’s the act of processing that concentrated and heightens the presence of off-flavours like these, making the processed foods made from them taste, well, processed. Good with the bad. You can’t concentrate for protein without concentrating other aspects of a plant. There’s always a cost. Now, I will always be a huge proponent for whole foods, made with care, prepared simply. But the realities of grocery store shelves dictate a different truth. People opt for convenience, and sometimes, you’ve got to meet them where they are. My current work at CH has me doggedly hunting down an effect of fermentation I’ve long known intuitively through practice. Certain lactic acid bacteria fermenting their way through legumes don’t just mask, but dismantle this and other problematic molecules. I’m still after the mode of action, but it’s also enough for me to know that age old techniques of fermentation (like soaking ones legumes or grains days in advance of their cooking) can still put to shame the greatest technological “advances” of food science of the past 40 years. Nature is, after all, cleverer than you are. "
