This article, found on ironMag, suggest that fat (among other substances as L-Glutamine, BCAAS, vit C) could inhibit cortisol:
Some preliminary studies show that vitamin C may also inhibit the catabolic actions of cortisol; however, the evidence is not particularly impressive. More likely, substances like branched-chain amino acids and even dietary fat are the nutritional cortisol inhibitors. Top
A new study reported at the 1997 meeting of the American College of Sports Medicine found that one of the branched-chain amino acids, leucine, successfully reduced the catabolic effects of cortisol in rat muscle without affecting muscle glutamine levels. That’s interesting because past studies showed that BCAAs work by either increasing muscle glutamine synthesis or preventing its release under the influence of cortisol. Top
Another study, reported at the Experimental Biology 97 meeting in New Orleans, examined the effects of dietary fats on plasma hormones in runners. The study compared three levels of fat composition in the diets of the runners: 17 percent, 32 percent and 41 percent. The results showed that the 32 percent fat diet significantly reduced cortisol levels in the runners compared to the 17 percent fat diet. Under the 42 percent, or high-fat, diet, cortisol levels increased only marginally. The diet lowest in fat produced the highest cortisol levels. Top
The authors of this study suggest that higher fat diets may help eliminate some of the excess cortisol release through an upgraded prostaglandin synthesis.
