Respecting food intolerances

some 10-15 years prior to my diabetes diagnosis, I was diagnosed with various food intolerances for which I took anti allergy medication for 5+ years. The most pronounced foods were dairy and nightshade veg. One result of being teted and diagnosed was that I lost a lot of weight (6 1/2 stone) in 6 months and more since ( now around 10 stone below heaviest weight) while I have been limiting the amount of those foods rather than continue with the Nalcrom meds
Impressionistically since diabetes diagnosis, I have thought that whenever I have had a period of ignoring the intolrances, my sugars become more erratic and slightly harder to control, so I finally decided 2 weeks ago to test it out by avoiding averything with a trace of dairy or nightshades in them while wearing one of mt stash of libre sensrs and also cross checking those results with finger pricks
What Ive found unfortunately matches my impressions.
Prior to experimenting the results Id entered onto MySugr, predicted an hba1c of 41.7, now it predicts 38.8. My libre results are aalso showing less variation than when I previously used them and much more time in target
Am I pleased - yes and no - I really like both food groups and can easily become somewhat addicted to dairy ( the dreams I had for a week or so when it was first excluded years back, were all incredibly vivid milk based ones ( drinking, bathing, milking animals were all in there along with some rather more left field ones revolving around milk). Im aso pleased that respecting the intolerances does seem to add something to the control pot

The change to flatter Bgs took 4 days
The loss of the symptoms of dairy intolerance like chronic rhinitis took about a week
The clinic that originally diagnosed my intolerances started off with a pretty hardcore 10 day exclusion diet of lamb, brown rice and pears , followed by skin and individual food testing to find suspect foods, then advised that food groups from which any food had shown up as suspect should not be eaten more frequently than every 3-4 days in order to allow inflammation to die down
Interestingly I read a whole heap of stuff about food intolerances after I was diagnosed with them, and a link between food intolrance and diabetes came up quite frequently. When I mentioned it when I was diagnosed as diabetic thonthe consultant endo dismissed it as “American nonsense”

I too eat a low carb diet - a bit more complicated with broader food intolerances but nowhere near impossible
Wrt potato - it is a member of the nightshade vegetable family so its carb count may not be the only issue. Nig - Tomatoes, peppers, aubergines, & tobacco are some other members of the nightshade family) are quite a common group for people to be intolerant to.
When I was tested, 2 cherry tomatoes blew my stomache up by 3 and a half inches and caused a whole upper body rash - on the basis of that the medics told me not to eat any nightshade veg
