Ha. Maybe I am confusing the two. I wasn’t in a rush to buy more back in those days.

Nutritional yeast tastes great. Easy way to get flavor without sodium. I think it activates the immune system though, for better or worse.

Nutritional yeast flakes were an old hack for vegans back in the 70s and 80s. Sprinkle on anything where you would traditionally have used grated cheese. Not great, but better than nothing!

Press coverage of this paper (that started the thread):
UW study: Mice live longer, healthier lives with less of one amino acid (isoleucine)
Mice fed a diet formulated to cut out two-thirds of their intake of isoleucine lived longer than mice in a control group. Male mice lived 33 percent longer, while females lived 7 percent longer. The mice were considered middle-aged when the study began, and still saw benefits from the change in diet.
“And they’re fitter throughout their lifespan, too,” said professor and metabolism researcher Dudley Lamming. “So they’re still able to run and climb, and they don’t grow as frail as normal animals do as they age.”
The mice also maintained steadier blood sugar levels and were less likely to develop cancer. Male mice experienced less age-related prostate enlargement.
Earlier research from UW-Madison showed that Wisconsinites with higher body mass index measurements ate more isoleucine. The amino acid is plentiful in foods including eggs, dairy, soy protein and many kinds of meat.
Lamming said he doesn’t expect his research to turn into a new fad diet. Humans need isoleucine to live and it would be difficult to even cut intake in half, he said.
But he said scientists may find ways to mimic the effect.
