Barley as a Stress Reliever: A Scientific Perspective
Barley (Hordeum vulgare) is primarily recognized for its nutritional benefits in the dietary realm. However, recent research suggests that this ancient grain may also have stress-relieving properties. This article delves into the scientific evidence supporting the claim that barley helps with stress.
The primary mechanism through which barley might reduce stress levels lies in its rich nutritional profile, particularly beta-glucans and selenium. Beta-glucans are a type of dietary fiber found abundantly in barley that have been shown to lower cortisol (the primary stress hormone) levels in animal studies [1]. Selenium, another essential mineral present in barley, functions as an antioxidant and may help manage stress by reducing oxidative stress in the body [2].
Beta-glucans are a significant component of barley's stress-relieving properties. Studies on rats have shown that beta-glucan supplementation led to reduced cortisol levels and improved anxiety-like behavior [1]. While human studies are still limited, these findings suggest that similar effects may occur in humans when consuming barley.
In addition to beta-glucans, selenium found in barley plays a crucial role in managing stress by acting as an antioxidant. Oxidative stress is often associated with increased levels of stress hormones [2]. By reducing oxidative stress in the body, selenium may help mitigate the negative effects of stress on various physiological systems.
While more human-focused research is needed to fully understand barley's role in stress management, existing evidence supports its potential benefits. Barley's rich nutritional profile, particularly beta-glucans and selenium, may contribute to reduced stress levels by lowering cortisol production and minimizing oxidative stress.
