I absolutely agree with you Mollygo. It really irritates me when people claim things like it's better to have cottage cheese. No, it's not, if you don't particularly like cottage cheese (which I don't) and know you won't enjoy it. The theory is that a little fat with carbs slows down the digestion of carbs and helps prevent sugar spikes in diabetics. If it works - and you like it - do it. I rarely eat potatoes anyway, but if I do, I'll have a few small pieces alongside a plate of protein, healthy fats and a mound of veggies or salad.
I've read so many times that porridge is good for people, so I've tried it a number of times. It's cheap too, so I'd love to eat more of it, but I know I can't. My plasma blood glucose levels two hours after eating porridge are sky high and it takes 24 hours for them to settle, even if I don't eat any carbs for the rest of the day. However, if it works for you, eat it!
When I was diagnosed with diabetes in my 30s, most people (including GPs) were clueless. I must have been diabetic for a while and nobody really knows why. I wish I'd known earlier what I know now because I might have had a chance to put diabetes into remission, but it's too late now. My pancreas is worn out and I have no option but to control the symptoms, which I know how to do with lifestyle. Not eating starchy carbs seems to cause people problems and I have been accused of eating a fad diet. No, I don't - I eat what is right for me and I can prove it's right with constant testing and my routine blood tests. So when people suggest eating a spoonful of something or adding an expensive supplement - or even going to the faff of making a green salad to eat before all the other salad and veggies I eat routinely, I just smile grimly and vow not to listen to that person again.
