@rustee2011 hi sorry to hear about your allergic reaction, one of my daughters gets a tingly lip if she eats prawns so fully aware that there are things out there that can disturb your balance.
In terms of diet, as someone who undertakes a high level of exercise and general activity I have focussed on consuming more calories without increasing my consumption of carbs. I have found that eating things like fish or meat as part of a salad with some avocado I can avoid the high BG while making sure I feel full and have plenty of energy.
I don't like raw cheese nor can I eat eggs outside of being mixed in a cake or bread. Yoghurt (particularly Greek) I can eat all day long together with some berries or half a pear. Therefore I use other sources of healthy fats together with eating slightly more protein to ensure that I have a good slow burn of food to keep my energy up. Some dark chocolate also helps to boost things particularly is my lunch or dinner has been especially low carb.
For things I used to eat a lot of like bread and pasta, I use substitutes such as red lentil pasta, or noodles made from edamame or black beans. These are lower cab but still fill me up. In addition I also enjoy the Fat Head Dough Rolls in the Freshwell app. When toasted you cannot taste any cheese and they are definitely a filling option.
