> Oatly compares their sugar to the sugar in cow’s milk, but they’re not the same sugar. Lactose, the sugar in cow’s milk, has a GI of 46. 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. The "glycemic load" is just the result of the multiplication of the sugar mass by the glycemic index: 7x1.05=7.35 and 12x0.46=5.52; it would be more clear to simply state that.
