I double-checked the amount of sugar in milk and in my area, Netherlands, all milk (whole or not) contains less than 5g of sugar per 100g. While Oatly has indeed about 7g per 100g. So it's quite the opposite, oatly has significantly more sugar with higher glycemic index.

The US nutrition label lists sugars per serving, which is 240ml. So according to the US rules it's 7g sugar per 240ml, not per 100g (or 100ml).

The US Oatly label lists "Total Carbohydrate 16 g, Includes 7 g added sugars" per 240ml.

The UK Oatly label lists "Carbohydrate: 6.6 g, of which sugars: 4.0 g" per 100ml. Pretty sure the Netherlands product and label is the same as the UK one.
