Unless youre bodybuilding or training in a similar manner then I dont see why you would supplement with any protein supplements let alone whey. Ive been bodybuilding for 3 years now and I never drink whey protein shakes because theyre shite in all honesty. If youre eating correctly then theres no reason you wouldnt reach protein goals through the diet. Protein only needs to make up around 15% of total calories per day.
Everyone should be aiming to eat a high carbohydrate (starchy complex carbs) whole foods diet abundant in fruit and veg (dark leafy greens should be eaten daily).
Sure, people
should be eating a well rounded diet with low glycemic index carbs, well rounded fats/meats and have no need for whey/soy protein shakes, but I have a hunch that some people aren't spending much time in the kitchen when they're struggling to get themselves out of bed
I wasn't necessarily recommending whey for effects on muscle protein synthesis, its caloric value or to help stave off muscle catabolism during stress/sleep deprivation, but rather I was thinking people need to be getting in their daily protein for brain related reasons.
See for example the effect of tryptophan deprivation on the brain, or protein's effect on sleep when taken before bed (it increases sleep, and so does supplementing with tryptophan purportedly).
I don't know why people are claiming protein shakes are garbage? Its amino acids, the building blocks of all your cells and neurotransmitters, and if you don't get them much in your breakfast and dinner then whey/soy protein is a fast and cheap option
The whey fraction has effects on insulin which can be beneficial for some but you can also just go with soy shakes too if you can stomach it
There is also something to be said for getting in enough daily fats/cholesterol for hormone synthesis, amino acids aside
And in regards to the gluten sensitivity, I wasnt suggesting everyone has it because they dont, but that a low glutamate diet may be worth a shot.
If glutamate was leaking through the BBB people would be having seizures (it is only actively transported into the brain and it's levels are tightly regulated, and it's non-essential as well), but anyways GABA uses glutamate as a precursor so if someone actually manages to make a significant impact on glutamate levels then it could also affect GABA levels
