Alternative Milks

| milk

I’ve not been getting out as much during Covid, as such I’ve tried to reduce my caloric intake. One way I tried to do this, was to switch the kind of milk I drink. This also had a secondary impact on reducing my environmental impact. However, while researching the various milks, I couldn’t find one source that put both nutritional information, and the environmental impact of the various milks in one place. This article does just that.

During my research, I found there are minor differences in the US and UK in how they represent this data. For example, a UK serving size is 200ml, whereas in the US it’s 1 cup (or ~240ml). I’ve normalised all values to the UK serving size.

I’m not going to provide any kind of editorial, I just wanted all the data in one place. The data is sourced from the following locations.
