I bought Tillamook because their cheese is good and I thought they’d make other good dairy. It seems like a rip off though. It’s fluff, so it weighs nothing. A serving of Tillamook has 30% less ice cream than a serving of regular stuff - 95 grams in 2/3 cup compared to 136 grams in 2/3 cup. The ingredient list isn’t as bad as others, but it’s got some odd stuff. In comparison, the Aldi stuff is just straight ice cream.
The OP article said the same thing, and like this article, it provides no evidence for the statement. I looked for some numbers, and for world bests, men had better performance in every category I found. The study linked below looked at speeds over decades and in every case men had better performance. Both men and women have improved over time, and as a percentage the difference is getting smaller, but in absolute difference it appears the same. It is an admittedly brief search, but I can’t find evidence in the form of measured times (not conjecture about estrogen) indicating at all that women perform better in ultra marathons. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3870311
