Ate with 10 of my family and I had roast turkey, sprouts, parsnips, carrots, avoided the roasties but allowed myself the stuffing and sausages as a treat (been avoiding nightshades and bread for the last 4 months and will continue now to do so). Could have had gluten free gravy if i was bothered about gravy. Also allowed myself a generous dollop of cranberries - 1st 'added sugar' in 4 months. Thoroughly enjoyed it all.
Had a luscious pint of green smoothie during the afternoon (pak choy, banana, pear and ginger). And a few dates & nuts for pud (never been a 'normal' pudding fan). As you suggest - meat and 3 veg perfect if avoiding dairy, nightshades & gluten.
I am avoiding dairy, nightshades and gluten to try and help my skin as Humira wasn't working. Now it is (with addition of metho) but I have really got into healthier eating and loving the daily green smoothies and have lost over a stone in weight (14lbs) which can only help my joints and over all health.
Hoping the diet will help skin in the long term whenever I may need to come off H and it does seem to be helping long term energy issues. I have no clear obvious signs of allergy or sensitivity but trying to maximise health and minimise inflamation.
