There is no shortage of stressors in today’s day and age. That includes everything from political news segments and social media clips to environmental pollutants and foods and drinks. As a result, the body’s primary stress hormone, cortisol, has become a hot topic of discussion in the health world. 

Cortisol plays a vital role in helping the body respond to stress, but chronic levels increase the risk of weight gain, high blood pressure, and insulin resistance. You can bring cortisol levels down through stress management techniques, such as deep breathing, meditation, and gentle exercise, but eating the wrong foods can cause cortisol levels to rise. Stay away from the following foods and drinks because they may trigger cortisol release. 

Refined Grains

Refined grains, just like other carbs, can spike blood sugar, which can potentially raise cortisol levels. These grains have been processed to remove fiber, which the body uses to lower cortisol levels, in addition to improving digestion and heart health. Some examples of refined grains include white rice, cereals, white bread, pasta, and pastries. Control the cortisol response with those foods by switching to their whole grain counterparts, which contain fiber.

High-Calorie Meals

Nutritional guidelines are based on a 2,000-calorie per day diet, but people can easily exceed that many calories in a day, especially if they eat out. A small 2023 study found that participants who consumed a 2,000-calorie meal  within 15 minutes showed significant increases in cortisol. Researchers attributed that response to the strain of processing such a large amount of calories in a short period of time. Most people typically do not mimic that scenario, but it does caution people to be more mindful about portion sizes and how quickly they eat. 

Fatty Foods

These foods are popular in the Standard American Diet. We are talking about red meat, fried foods, and full-fat dairy, all of which have been linked to increased cortisol levels. Eating large amounts of these foods may also increase inflammation in the body. Over time, chronic inflammation can interfere with the body’s stress response, leading to cortisol spikes and unnecessary stress. 

Caffeine

This is the most common drug that people are addicted to, and they drink it at all hours of the day. Be it a double shot of espresso in the morning or an energy drink after lunch, caffeine provides you with both a jolt of energy and a cortisol surge. Caffeine blocks receptors for adenosine, the “fatigue molecule in the brain, making you feel more alert. It also triggers the release of excitatory hormones, such as cortisol and adrenaline. A 2025 study on the cortisol response from beverages containing caffeine found that coffee had the most significant impact. It actually increased cortisol by up to 50% above baseline levels. Energy drinks and soda followed with a 30% increase, while tea had the lowest impact of a 20% increase. 

Juice

Natural sugars are not nearly as bad as added sugars, but research suggests that there is a sugar-cortisol response in concentrated amounts of natural sugar. A small study from 2020 found significant cortisol responses to people who drank 200 milliliters (6.8 fluid ounces) of grape juice. A quick note about grape juice: it typically contains a higher percentage of natural sugars compared to other juices. 

Ultra Processed Foods

Chips, deli meat, soda, packaged sweets, and soda fall into the category of ultra-processed foods. These foods tend to contain high levels of added sugar, sodium, additives, and preservatives, which may elevate cortisol levels. Ultra-processed foods can also increase inflammation and spike blood sugar, both of which put stress on the body. Some research indicates that people who eat more ultra-processed foods tend to have higher stress levels. 

Alcohol

Wine, beer, and hard liquor are famous for triggering cortisol production. In fact, studies show that having a single drink per day is enough to increase cortisol levels. That effect is even more pronounced in binge drinking, which is defined by having five drinks for men or four for women within two hours. That is because the liver has to work overtime to break down alcohol, putting stress on the body and triggering the release of cortisol.
