Your skin looks really nice! Really! I understand it can be hard to find those triggers. I personally don't have any itching or red bumps on the rest of my body (yeah, body acne...).
I found an institute here in the Netherlands that can test for many many food allergies or sensitivities (on all popular foods) and also for the products you mentioned. I think it would be very helpful if I took those tests, that will show where I'm sensitive for. I think it's more about avoiding your personal triggers, rather than avoiding anything. At least, I think that's the way I will do it do keep on doing it. There's no way I could otherwise stick to it.
I think in may/june I will pump up the lifestyle even more. I will swtich my whole grain bread to whole grain spelt (organic) and for breakfast some eggs. At night just quinoa or brown rice. I already eat about 300/400 g of vedgetables.
I started eating garlic since yesterday, because I read somewhere it was just as strong as an antibiotic, but I read controversal stories so we will see how that goes!
Weirdly, the acne seems to be a bit worse than last year around this time, while I'm eating healthier, less stress and taking more care of myself. Hmm..
