The Walnut’s Health Benefits

1. Vitamin E, Melatonin, and Polyphenols

Vitamin E is a powerful antioxidant in walnuts, especially in the nut’s papery skin. Vitamin E plays a key role in reducing oxidative stress, which helps protect your cells from damage. Walnuts are the most omega-3-rich nut, with an impressive 2.5 g of ALA per 1 oz serving. ALA is a plant-derived omega-3 that you need to get through your diet to maintain good health. Studies show that higher ALA intake can reduce the risk of heart disease, arrhythmias, and other chronic diseases. Eating walnuts can also help reduce inflammation, which is the root cause of many chronic diseases. ALA helps protect against oxidative stress, inflammation, and other types of oxidative stress. 

In addition, walnuts contain polyphenols, which are converted into urolithin compounds by beneficial gut bacteria. This helps to maintain a healthy gut microbiota, which is important for overall health. Eating walnuts can help improve gut health and reduce the risk of obesity, heart disease, and other health issues.

Walnuts may play a protective role in overall health.

Studies have shown that walnuts may reduce the risk of developing certain types of cancer, including breast cancer, prostate cancer, and colon cancer.  When converted to urolithin by intestinal microbes, walnuts produce anti-inflammatory compounds that may help protect against colon cancer. These compounds may also interact with hormone receptors to reduce the risk of hormonal-related cancers.

Keeping your blood pressure in check is essential for your heart's health. Studies have shown that walnuts may help lower blood pressure, particularly in people with hypertension.
