I think we might be well past the days of honest natural sport. Thats not me saying we should be cheating, but trying to get back to that isnt possible, we have to figure this out moving forward not just for women or trans people but for all the other ways science affects sports.
Its not natural that someone with enough money for the best training science can provide them is almost guaranteed to be in the top percentiles of their sport.
What’s interesting is that this has been true since at least roman times, with funding going towards training and gear, even if the participants themselves might not be wealthy.
Quite a lot of people experience physical discomfort or pain from eating the things you listed.
A good portion of the world is lactose intolerant, justtpo point out an obvious one.
Meat can cause a “spike followed by a come down” effect somewhat similar to sugar in some people.
But what I think happens is that people dont make the connection between how they feel and their diet.
