Since the GI is a measure of how much of a negative response your body has to certain sugars, the 7g of sugar in Oatly with its 100+ GI is actually potentially worse than the 12g of sugar in whole milk with a 46 GI. We can use something called the “glycemic load” to measure this, which gives us a GL for the sugar in 8oz of Oatly of 7.35, and a GL for the sugar in 8oz of whole milk of 5.52. Oatly’s glycemic load is about 33% higher than milk’s is!
This is a bit of a dubious paragraph. GI is not a measure how much of a negative response your body has to sugar. It is simply how quickly carbohydrate turns into energy, as far as I understand.
Comparisons to coke are also a bit far-fetched. Like, people who get obese from drinking fizzy drinks are probably drinking a whole lot more fizzy drinks than the average oat milk consumer is drinking oat milk. No one is sitting and drinking 2 litres of oat milk while watching TV.

Thought this was an interesting read. If anything because it made me think about the sugar content more than I have done in the past.
