I hadn’t heard any of this and on first reading it’s a bit scary. But I’m sticking with my Delicious Delilah’s kefir output and if I want yogourt, I won’t buy Greek; I’m way more likely to make it myself and not strain it. This current approach to food and marketing is not going anywhere I want to live . . . how about you?
On second reading, I’m thinking the problem likely goes back to manufacturing ‘food’ in factories instead of in the home. When I made yogourt, I did so in gallon jars. We ate it whole and there were no by-products to dispose of. If there had been, I would likely have used the whey when I made bread or pancakes, etc.
Well, too much thinking is hurting my brain . . .
