I’ve been scouring the PubMed database reading up on insulin sensitivity, fish oil, supplements and other nutritional info. It struck me that most of these studies are done on diabetics, obese, or elderly people. It finally occurred to me that that’s who needs the help - or more cynically, the meds.
What’s to gain in understanding people who are already healthy? And, you don’t have to do studies to sell supplements to healthy people, because you’re not claiming that you can make them better.
So, it leads me to question the validity of conventional wisdom about supplements, which now seem to be misappropriated from studies involving populations whose response does not match that of healthy adults. Specifically, most of the advise I’ve come to believe from this site would probably more accurately be prepended with “For diabetics…”
I guess this should be no surprise, that for healthy people, bodybuilders or not, supplements are really not necessary, if you have a healthy balanced diet- which consistently is reported as high fiber, low saturated fat, regardless of macro breakdowns.
All the magical properties of supplements only come into play if you are severely deficient in something to begin with, typically because of some disease or enzyme disorder.
That’s not to say there’s nothing to learn about nutrition for performance, but it seems pretty simple, and does align with the bodybuilding standard of sugar only around exercise, frequent fiber and protein meals, and a variety of fruits, vegetables, and lean proteins.
An interesting point, is that any non-bodybuilder considers high protein around 1g/kg, which would be considered criminally low around here, and except in the context of ketogenic diets, low carb seems to describe anywhere below 40% of calories, which again, on this site, would be considered a high carb bulking diet.
The most surprising detail, since I’ve read over and over from members and authors here that fish oil improves insulin sensitivity, is that consistently, in any study with healthy adults, it does not.
EDIT: I want to summarize.
- Common knowledge about nutritional supplements seems to be based on their effect on diabetics.
- You have to NEED supplements to gain their benefit.
- You are most likely not going to be limited in any way by a lack of supplements.
