Are Walnuts Keto?

1 oz of walnuts contains 1.98g of net carbs. With less than 2g of net carbs per serving, but 19g of fat and 4g of protein, walnuts are considered keto-friendly. [1]

Why You Should Go Nuts Over Walnuts

Walnuts have numerous health benefits. In fact, walnuts have greater amounts of antioxidants than any other nut. Walnuts are high in Vitamin E and polyphenols (plant-based phenols that function as antioxidants). [3]

Walnuts may also help with inflammation. Of the 19g of fat per serving, about 3g is from alpha-linoleic acid (ALA), an omega-3 fatty acid. ALA has been shown to help reduce inflammation and may even decrease your risk of cardiovascular diseases.

Additionally, walnuts are also high in magnesium and arginine, both of which have been shown to reduce inflammation. [4] [5]

One polyphenol that walnuts are rich in is known as ellagitannins. Ellagitannins can be converted into urolithins in the gut. Urolithins not only have potent anti-inflammatory properties but have been shown to protect again prostate and breast cancer. [6]

Benefits of Walnuts

Moreover, walnuts have also been shown to be beneficial for male reproductive health. Research suggests that consuming walnuts may help improve sperm health by reducing oxidative damage. [7] [8]
