Peanut butter contains a phytosterol called beta-sitosterol, which may be believed to help reduce cortisol levels and modulate the body’s stress response.
Peanut butter is a dietary item that is made from peanuts by crushing it into small pieces and then grinding it into paste.
It is a great source of important nutrients like protein, good fats, vitamins (such as vitamin E), and minerals (like magnesium and potassium).
In terms of how peanut butter affects cortisol levels, cortisol is a hormone secreted by adrenal glands in response to stress.
Despite a lack of direct scientific studies on the specific effects of peanut butter on cortisol levels, some research suggests that some peanut-derived compounds may have stress-relieving effects.
Several bioactive substances found in peanuts, such as polyphenols and antioxidants, have been related to anti-inflammatory properties. Further, we’ll discuss in the article, does peanut butter lower cortisol level or not. And other important points related to the same.
What is Cortisol?
The adrenal glands release the steroid hormone cortisol in reaction to stress. It is crucial for the body’s reaction to stress and aids in the control of several physiological functions.
Blood pressure, immune system performance, metabolism, and the body’s inflammatory response are all impacted by cortisol.
It is frequently referred to as the “stress hormone” since it is produced when people are under stress.
Naturally, cortisol levels vary throughout the day, peaking in the morning and progressively dropping during the rest of the day.
However, a persistent or chronic increase in cortisol levels can have harmful effects on health, such as an increased risk of anxiety, depression, weight gain, and immune system impairment.
Role of Cortisol in the Human Body
The human body needs cortisol because it helps control several physiological functions.
It is essential for controlling blood pressure, immunological response, metabolism, sleep-wake cycle, memory and learning, mood modulation, and bone health.
Cortisol aids in the body’s reaction to stress, energy maintenance, anti-inflammatory activity, blood pressure regulation, wakefulness promotion, support for cognitive processes, and normal bone turnover.
However, cortisol imbalances can have a detrimental impact on health, emphasizing how crucial it is to maintain normal levels for general well-being.

Does Peanut Butter Lower Cortisol?
While peanut butter is a nutritious food, there is limited scientific research specifically investigating its impact on cortisol levels. However, peanut butter contains several bioactive compounds that may potentially influence cortisol.
One such bioactive compound beta-sitosterol is present in peanuts, and due to its high concentration of beta-sitosterol, a plant sterol with anti-inflammatory and stress-relieving properties, peanut butter has been linked to a possible reduction in cortisol levels.
It is thought that beta-sitosterol may help reduce cortisol levels and modulate the body’s stress response. To completely comprehend the connection between beta-sitosterol, cortisol levels, and peanut butter, more research is necessary.
One study published in the Journal of Clinical Endocrinology & Metabolism investigated the effects of a high-fat meal on cortisol levels.
They found that consuming a high-fat meal led to a transient increase in cortisol levels.
Although peanuts were included in the high-fat meal, the specific effects of peanut butter on cortisol were not isolated in this study.
Peanuts are rich in healthy fats, including monounsaturated and polyunsaturated fats. These fats have been associated with lower cortisol levels and improved stress response in some studies.
Another study published in the Journal of the International Society of Sports Nutrition examined the effects of a high-protein snack on the cortisol response following exercise.
The study found that consuming a high-protein snack, which included peanuts, helped attenuate the rise in cortisol levels after exercise compared to a control group.
However, the study did not solely focus on peanut butter or directly investigate its effects on cortisol.
Peanuts are a good source of protein, which can help regulate cortisol levels. Adequate protein intake has been linked to better stress management and reduced cortisol release.
It’s important to note that while these studies provide some insight into the potential impacts of protein-rich snacks and high-fat meals (which may include peanut butter) on cortisol levels, they do not directly prove that peanut butter alone lowers cortisol.
Therefore, further scientific studies are needed to establish a direct relationship between peanut butter consumption and cortisol regulation.
