I've just been doing some research on niacin and rosacea. It seems in high doses it causes blood vessels to dilate, flushing and itching.
Some foods high in niacin are salmon, chicken, butternut squash. This is a bit worrying as I eat those foods every day! I stay away from beef and am possible allergic to pork and lamb.
Should I be avoiding these foods or will an antihistamine and aspirin a day neutralise any niacin effects? or should I just not worry about it any carry on eating what I already do?
