The Claim

In healthy young men, ingestion of glucose prior to psychosocial stress results in a greater cortisol response, as measured by absolute cortisol levels and net cortisol increase, compared to ingestion of protein, fat, or water.

Source: Glucose but not protein or fat load amplifies the cortisol response to psychosocial stress.

What the research says

Supports is higher

Support is ahead, but a single strong opposing 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.

Cause and effect
1 study reviewed
In plain English

If a young man drinks sugar water before a stressful situation, his body releases more of the stress hormone cortisol than if he drinks protein, fat, or just water.

What the research says

1 study
  1. Study: Glucose but not protein or fat load amplifies the cortisol response to psychosocial stress.

    When healthy young men drank sugar water before a stressful test, their stress hormone (cortisol) went up more than when they drank protein, fat, or plain water — so sugar makes the stress response stronger.
