The Radical Feminist Dietitian agenda was pointed out long ago in such books as Ann and Bill Moir's "Why Men Don't Iron - The Real Science of Gender Studies" 1998,
Chapter 2 "Foodsex 1 Perhaps he's a rabbit"
Chapter 3 " Foodsex 2 Where's the beef"
each chapter of which has plenty of references to the scientific papers at the time.
It points out such unaddressed anomolies as the recommended diet by these radical professionals for first-world women, being pretty much the same as the diet that typical third-world women are forced to endure - from which they get shorter life expectancy and high infant mortality. And it addresses the differences in dietary needs between men and women, concluding in one part that based on NASA's healthy diet, the first person to land on Mars will likely be a woman, as there is no way most men could endure the trip.
Check the Harvard Study you linked to - 84,000 women in one study and 38,000 men in the other - and no mention of any difference between the sexes. And no account of why both groups have continually increasing life expectancies, despite the supermarket shelves being full of meat. Such agendas develop a life of their own, especially when coupled to saving the planet.
As an aside, Ann Moir's earlier book "Brainsex" explained the profound differences in brains and brain fucntion between men and women, as discovered in laboratory studies. Subsequent studies by others have only confirmed what she found, and expanded upon it. In sharp contrast to the gender fluidity pseudo-science now being taught in schools.
