Mediterranean diet protects heart health in multiple ways
Applauded for reducing your risk for obesity, high cholesterol, and high blood pressure, a new study shows that a Mediterranean diet helps your heart in another way as well.
The diet, which gets much of its protein and fat from plants, can help ease stress, according to a study from researchers at the Wake Forest School of Medicine.
That’s good news for your heart, as persistent stress increases the risk for heart disease. That’s because your heart rate and blood pressure rise when you’re faced with a stressful situation, as do levels of the stress hormone cortisol. When heart rate, blood pressure, and cortisol levels don’t subside, your heart suffers.
To examine the stress-relieving impacts of a Mediterranean diet, researchers fed animals either a Mediterranean diet or a Western diet, which is higher in animal protein, saturated fat, salt, and sugar.
The study found that a Mediterranean diet helps support the parts of the nervous system that help the body calm down. It enhanced resilience and was linked to a more rapid recovery after stress ended.
A Western diet increased the fight or flight response to stress, which researcher Dr. Carol Shively likened to the unhealthy response of “having the panic button on all the time.”
Adopting a Mediterranean-style diet can be a relatively simple and cost-effective way to reduce the negative impacts of stress.
For many reasons, it can be an effective way to support heart health.
What's a Mediterranean diet?
