The medical community is finally starting to notice that glucose instability is causal to cardiovascular conditions, after all we just had 40 years of denigrating meat and fat, promoting high carb diets, ending with a major increase in T2D and cardiovascular disease.
I mean for crying out loud it's right in our faces, yet some biochemists were making this very point by the early 90's.
Even worse, doctors who treated diabetes (T1) in the early 20th century already understood reducing simple carbs and increasing fat and protein was the way to help manage T1.
Thanks for the links
Says who?
I've seen plenty of small kids on wrist leashes since the 80's.
Also, there's a vast difference between a kid and even a dog, when it comes to autonomy - your goal is to slowly develop a kid's autonomy so they can be independent. Some kids/circumstances can be very challenging to negotiate safely.
With dogs, you have to do the reverse - condition them so they'll want to defer their autonomy to you. And with some dogs, even with the best, most capable trainers in the world they'll still dart after that rabbit or whatever catches their eye.
