There's no shortage of rules about what people with
type 2 diabetes should and shouldn't eat. Avoid refined carbs. Limit sugar. Eat
more fiber. Pair carbohydrates with protein. These guidelines are
evidence-based and generally useful — but they're also generic, and blood sugar
response is not a generic phenomenon. It varies significantly from person to
person, and even for the same person it varies depending on portion size, food
combination, timing, stress level, and sleep quality.
This is the core problem with following general
dietary rules as the primary management strategy: they tell you what works on
average, not what works for you specifically. A food that causes a significant
spike in one person may be well-tolerated by another at the same portion. A
meal that is stable in the morning may produce a different response in the
evening. The rules are a starting point. Personal data is what makes management
actually precise.
