Stress is often associated with work, conflict, or unexpected events. However, the source of tension can be much closer to home—on our plates. Certain foods and drinks can stimulate the release of cortisol, the main stress hormone, affecting mood, energy levels, and overall well-being.
Experts point out that the cause of anxiety is not always external circumstances. Eating habits can trigger hormonal fluctuations, which the body perceives as a danger signal.
Salty packaged snacks
Chips, crackers, flavored snacks, and frozen meals are loaded with salt, simple carbohydrates, and saturated fat. This combination can raise blood pressure, cause inflammation, and disrupt the balance of gut microbiota, which directly affects cortisol levels. A healthier alternative is to eat raw nuts, seeds, or minimally processed baked snacks.
Alcohol
Alcohol is often perceived as a way to relax, but its effect is deceptive. Initially, cortisol levels do decrease, but then there is a sharp “rebound” - the stress hormone increases. Regular alcohol consumption can disrupt sleep and increase anxiety. The best choice would be moderation, alternating alcohol with water or non-alcoholic drinks.
Energy drinks
High doses of caffeine quickly activate the nervous system, but at the same time increase cortisol. The result can be tremors, irritability and sleep problems. A milder alternative is green tea, which contains less caffeine and has a more balanced effect.
Packaged sweets
Candy, cookies, and processed desserts cause sharp spikes in blood sugar levels. The body perceives these spikes as stress, which triggers the production of cortisol. Instead, choose fruits, berries, or dark chocolate in moderation.
Sweet carbonated drinks
Sugary sodas spike glucose and insulin levels, which triggers a hormonal stress response. Much healthier alternatives would be water with berries or citrus fruits, herbal or green tea.
Sweet coffee cream
Coffee supplements with sugar and artificial sweeteners can cause a morning “cortisol surge” and upset stomach. Natural milk or plant-based drinks without added sugar can help avoid this effect.
What to remember
Stress doesn't always manifest itself abruptly—sometimes it builds up gradually through everyday little things, including food. Conscious food choices can help reduce hormonal stress, improve mood, and reduce anxiety. It's not about strict prohibitions, but about replacing foods that are aggressive to the body with more balanced and "calm" alternatives.
