The Claim
In healthy young men, ingestion of protein, fat, or water does not significantly amplify the cortisol response to psychosocial stress when compared to ingestion of glucose.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you're a healthy young man and you eat protein, fat, or drink water before a stressful situation, your stress hormone (cortisol) doesn't go up much more than if you'd eaten sugar instead.
See the scientific wording
Ingestion of protein, fat, or water does not significantly amplify cortisol response to psychosocial stress compared to glucose in healthy young men.
What the research says
1 studyStudy: Glucose but not protein or fat load amplifies the cortisol response to psychosocial stress.
The study found that only sugar (glucose) made stress hormones go up more than usual — protein, fat, and water didn’t. So saying they all have the same small effect is wrong: sugar is special here.
