Every food commercial, advertisement, and packaging in the US is currently protein obsessed. I just bought 3 burritos, and the most noticeable thing on the entire package is its protein content. TV commercials about waffles are advertising that they have X amount of protein per serving. The products in my jobsite’s vending machine have protein all over every package.
Did America have a protein thing recently?
I’m not sure which of us misunderstood it, but my interpretation of their findings is that overall, increased protein intake was not associated with increased athletic performance. However if you look ONLY at endurance, it was actually associated with high performance, though only when alongside carbs. Maybe counterintuitive.
Their total sample size was around 300 or 400 iirc. Pretty big, but could be better.
