After the disappointing tests with resistant white rice I checked the next family of foods high in carbs: lentils. Legumes are said to be filling and have low impact on blood sugar. So why not try a can of lentils?
To make things easy and reproducible I chose to open a can of french precooked lentils with sausages (I live close to the french border and sometime buy food there – uhm and wine…).
Conveniently they put the nutrition values for one person on the label: 33g of carbs (see NB below).
I assume most of the carbs come from the lentils as the other ingredients (sausage and spices) are not carb-rich.
Result for foods high in carbs – Lentils
Here are the results from the Freestyle Libre Flash Glucose Meter: now that looks very nice: a BG rise of only 18 mg/dl from 34g of carbs.
NB: in some countries (like US) the total carb value does contain the fiber amount as well. I do not know how the french are doing it but even if I subtract fiber from total carbs – for 23g of carbs this is still a gentle rise.
