I just invested in a new camping cooler- a Yeti. I did so because being a Type1 means I always have to have the right food with me and water. The nice thing about the cooler is once packed it literally keeps food cold for 48 hours! So I can throw in some yogurts and fresh fruit, cheese sticks and left overs and I am good to go.
I have quite literally left my car in the sun all day in the parking lot and came out to find the ice still solid and my food cold.
I also recently had my endocrinologist recommend Larabar health bars, as working the best for maintaining stable BG for several hours. I have found this too be a useful tool, albeit they taste like peanut butter paste to me. I eat them, because they’ve worked for me.
Being a diabetic, means being prepared- it’s a drag, but a necessity. I also do a lot of hard boiled eggs.
When your in trouble- protein works the best in terms of leveling you out. Low sugars need to be treated, followed by protein.
Good luck! With all of the easy to prepared salads and chicken, things are much easier than they used to be!
