Cortisol is an essential hormone that helps regulate blood sugar and supports immunity. While it is normal for this hormone to increase during stress, prolonged elevation can harm health.

Fried foods

French fries and fried chicken contain saturated and trans fats, which can cause inflammation, oxidative stress, and stimulate the body to release cortisol. These items are also rich in refined carbohydrates, leading to increased blood sugar, which in turn prompts the body to produce cortisol to rebalance.

Alcohol

Alcoholic beverages alter blood sugar levels, leading to excess cortisol production. Individuals who regularly consume large amounts of alcohol often have persistently high cortisol levels, contributing to health problems such as: high blood pressure, weight gain, and sleep disorders.

Caffeine

Drinking a cup of coffee in the morning provides energy to start the day, but it can also cause a short-term spike in cortisol levels, especially when consumed in large quantities. Caffeine in coffee is a central nervous system stimulant, which can increase cortisol secretion, particularly when consumed on an empty stomach, in high doses, or by individuals sensitive to caffeine.

Ultra-processed foods

Ultra-processed foods like: packaged snacks, cookies, cereals, and fast food contain preservatives, saturated fats, and refined carbohydrates. Regularly eating these foods can cause inflammation, activate an immune response, and produce excess cortisol.

Added sugar

Sweets can provide immediate comfort but contain added sugar that affects cortisol levels and the body's stress response. Rapidly digested sugar easily increases blood sugar. Additionally, consuming sugary foods negatively impacts gut health, disrupting the microbiome, and reducing the body's ability to regulate its stress response.
