Well, as reactive hypoglycemia tends to occur after eating high-carb meals due to the fast spike and then crash
of blood sugar, I would focus eating foods that do not cause this. Stay away from heavily processed starches (pastas, cereals, breads) and get your carbs from healthy sources like sweet potatoes, spinach, peppers, and other vegetables. A white rice or quinoa would be alright in small amounts and in moderation.
