Cortisol is a steroid hormone produced by the adrenal glands. It helps regulate the body’s response to stress and affects many systems, from metabolism to immune function.While short bursts of cortisol are normal, Christine Ferguson, ph.D., RDN, assistant professor in the University of Alabama at Birmingham‘s department of Nutrition Sciences says chronically elevated levels can increase the risk of long-term health conditions.
“Diet influences many things, including cortisol, through the inflammatory pathway,” Ferguson said. “Inflammation is a key factor as increased cortisol can raise inflammation, and inflammation can also raise cortisol. Diet can influence both. That’s why anti-inflammatory foods or an anti-inflammatory dietary pattern is worth considering.”
The Cortisol-Inflammation Connection
The relationship between cortisol and inflammation is a complex feedback loop. Chronic stress leads to elevated cortisol, which, over time, can trigger a systemic inflammatory response. This inflammation, in turn, can further elevate cortisol levels, creating a vicious cycle. Diet plays a crucial role in modulating this cycle. Foods high in processed sugars, refined carbohydrates, and unhealthy fats tend to promote inflammation, while those rich in antioxidants, omega-3 fatty acids, and fiber help to dampen it.
Anti-inflammatory foods often include antioxidants, which are found mostly in fruits, vegetables, legumes and whole grains. When it comes to meats, the picture is more nuanced. Fish are considered anti-inflammatory becuase of thier omega-3 fatty acids. Other animal proteins, such as chicken and beef, provide beneficial vitamins and minerals; but fat content matters. lean options like chicken breast
