Yes, milk, particularly whey protein found within it, may be beneficial for managing cortisol levels.
Here's a breakdown:
-
Calcium's Role: Diets low in calcium can stimulate cortisol production in visceral adipose tissue (belly fat). Ensuring adequate calcium intake, which milk can provide, may help regulate cortisol.
-
Whey Protein's Impact: Studies suggest that consuming whey protein, a component of milk, can reduce both basal (normal) and stress-related levels of circulating salivary cortisol. This is significant because elevated cortisol levels, especially during stress, can have negative health consequences.
-
Mood and Cognitive Benefits: Furthermore, research indicates that whey protein may improve mood and cognitive function, which are often negatively affected by high cortisol levels.
In summary, milk, especially due to its whey protein content, appears to offer potential benefits for managing cortisol levels, improving mood, and supporting cognitive function. While more research is always valuable, these initial findings are promising.
