> White rice has one of the highest glycemic indexes. This is correct, but do keep in mind the impact that cooling down has on starches. A fresh bowl of rice is very high, but cool it for a couple of hours and the GI drops considerably. Cool it overnight and it drops even more. Onigiri is usually in the cooled down to over-night range. This never makes rice particularly good from a GI perspective, but preparation is a considerable factor. --- One study, but this is fairly well reproduced: https://pubmed.ncbi.nlm.nih.gov/26693746 https://pubmed.ncbi.nlm.nih.gov/26693746 And a more general write up: https://www.diabetes.org.uk/guide-to-diabetes/enjoy-food/carbohydrates-and-diabetes/carbs-and-cooking https://www.diabetes.org.uk/guide-to-diabetes/enjoy-food/car...
