Unfortunately there isn’t one simple recommendation that would suit everyone.
Total carbohydrate content is certainly the aspect of a meal which is most likely to impact blood glucose levels, but within that are all sorts of variations and imponderables - because people can have quite different reactions to different sources of carbs.
When told they are at risk of diabetes, some people on the forum have found it helpful to simply cut right back on sweet and sugary things (including fruit juice and some fruits), and to generally aim to reduce portion size of carbohydrates in their meals.
For more precision, others choose to self fund a BG meter so that they can check immediately before eating, and again 2hrs after the first bite to aim for a rise of 2-3mmol/L or less. By keeping the ‘meal rises’ down to a moderate level (even if readings are a little on the high side to begin with) the overall BG levels can gradually come down over time. Plus of course this approach can free you up to eat the sources of carb your metabolism copes well with, and shows you where others (even some thought of as healthy or slow release) don’t suit you so well.
If you like the sound of this approach, it helps to choose a meter which gives reliable results for reasonable cost. The most affordable meters members here have found are the
SD Gluco Navii or the
Spirit Tee2 - which both have test strips at around £8 for 50 (some other brands would be £25 or more for 50 strips!).
Good luck and let us know how you get on
