Everyone reacts differently to various foods. I avoid most of the "superfoods" (turmeric, spinach greens, almonds & most nuts, etc which are claimed to be anti-inflammatory) as most of them are high in oxalates, no good for joint ailments for some of us. Ginger is moderately high in oxalates but I do have the occasional teaspoon of crushed ginger in stirfry with no ill effects. I've no idea about the effects of alcohol on PMR, but I quit drinking years ago. Cutting out things that are no good for us is always a good idea.

Sugar of any kind is inflammatory, even sugar that occurs naturally in fruit (and wine!) So are carbs, because they turn to sugar to burn as calories. You want to keep your sugar as low as possible, so kicking wine out is worth a try. Opt for berries in your diet as they are low in sugar. And low carbs. High quality proteins, lots of greens and non-starchy vegetables of all kinds, and healthy fats (avocados, olive oil, coconut oil, etc) is what works best for most people. Everyone is different.
