Interestingly enough, there are now non-animal whey milks out there (made via fermentation). It’s worth noting that protein bioavailable numbers are pretty misleading because the way they are done overvalues the availability of animal products and undervalues it for plant-based foods

While multiple strengths characterize the DIAAS, substantial limitations remain, many of which are accentuated in the context of a plant-based dietary pattern. Some of these limitations include a failure to translate differences in nitrogen-to-protein conversion factors between plant- and animal-based foods, limited representation of commonly consumed plant-based foods within the scoring framework, inadequate recognition of the increased digestibility of commonly consumed heat-treated and processed plant-based foods, its formulation centered on fast-growing animal models rather than humans, and a focus on individual isolated foods vs the food matrix. The DIAAS is also increasingly being used out of context where its application could produce erroneous results such as exercise settings. When investigating protein quality, particularly in a plant-based dietary context, the DIAAS should ideally be avoided.

I’m not vegan. I just don’t drink milk and I’m certainly not advocating veganism because you don’t have the ability to commit to 10 minutes to make your own oat milk so howTF are you going to make such a lifestyle change?

All I did was say how easy it is to make yourself as you complained about the cost and when you bleated about your very busy important lifestyle, laid out your options.

It’s quite obvious the biggest hurdle to you making changes to your life is you so good luck with that and I hope it works out.
