Hi @scarlettoh, have you had any success in fighting your LS?

One diet change that is scientifically proven to reduce the severity of a range of autoimmune disorders is the reduction of salt in the diet while making sure you get enough potassium. Salt triggers inflammation. As far as I know there are no studies specifically on LS (well studies in MS, LSE, etc.), but since there are other benefits to reducing salt intake I would recommend trying for yourself. I would try to avoid all processed foods and fast-food as these can contain more sodium in a single serving than the salt used in a week's worth of home cooked meals. (If you want to read more about this google "T-helper 17 (Th17) cells"). One option is to use a potassium based salt substitute.

I would not try avoiding (properly cooked) legumes, nuts (w/o added salt) or nightshades unless you have personally experienced problems including these in your diet. It might make sense to avoid or limit meat though since these are inflammatory.

I am using clobetasol propionate to control my LS symptoms. I used Nigella sativa oil to treat my Hashimotos, but I have stopped taking the oil after I switched to a (more or less) vegan, whole plant food based diet, which made all my Hashimotos symptons disappear (for now...). Speaking of Nigella sativa, I recently found the below study where they used Nigella sativa cream to treat oral LP. Not sure who funded this study, but it would be wonderful if this will also be effective for LS. (I couldn't post the URL as I am a new member...)
Perhaps someone else on the forum has tried this?
