In my early months of PFS, I was still dedicated to a fully vegan diet that I had already done for about 3 years prior. I ate lots of soy-based meat replacements. (Tempeh was wonderful in my spicy curry instead of chicken!) I never had any nutritional or health problems in those years. Certainly not sexual ones.
Given that PFS is induced by an anti-androgenic endocrine disruptor, I didn’t want to risk skewing my hormones one way or the other. Soy has been shown to behave as both estrogenic and anti-estrogenic according to studies, which are quite conflicting conclusions and it makes it a complex issue where there are differences involved between different soy-based products and their various methods of processing.
Then there’s couple of reports from people who had adverse effects that they personally attributed to soy food consumption, so I got scared off of it. I don’t really know whether I have given in to fearmongering or whether there is truth to it, but I didn’t want to take a potentially big risk out of pride.
So I went back to a more regular / varied omnivore diet, in hopes my body would ‘heal better’ if it had a slightly different nutrient intake. I never really consciously avoided 5-ari foods or anything like that (it would help to have a comprehensive list of 5ari foods and their potency/risk factor per weight) and I would say that my personal condition has been overall very stable, with some mild fluctuations.
I did see minor improvements over time in my condition, but these could very well be due to time and there was no notable ‘sudden-ish’ change in symptoms for me that I can definitely attribute to the diet shift.
I have also tried alternatives for soy-protein, like chickpea-based protein. I seemed to have no problems with eating those, but a non-soy vegan diet was a bit too shake-dependent and unsatisfactory for my tastebuds to remain fully enjoyable. I don’t like quinoa, lol.
I also consume(d) coconut-based products like coconut oil and coconut milk on the regular (still do) and I do not feel these have any adverse effects on me personally. Oat / almond milk are also fine.
Most brands of those products that I consumed back then are Dutch (vegetarian butcher, etc.) but there are a couple of brands that I believe are more international, Vivera and Quorn for example.
Alpro and Oatly for drinks. I have never had problems with any of their stuff.
That said, I have not consumed much soy-heavy foods after I got PFS and switched diets, so I’m not sure if I can really promote it all as safe.
Hope it helps
