Walnuts are incredibly nutritious, as they are packed with minerals, vitamins, and fiber. They're also a good source of protein and healthy fats, which are linked to keeping you full longer and helping you control your cholesterol levels.

Walnuts have the highest level of antioxidants among all types of nuts. It's attributed to the melatonin, plant compounds, and vitamin E that are present in the nut and its papery skin. Eating a handful of walnuts every day can lower your bad cholesterol level, known as LDL or low-density lipoprotein.

In addition to providing your body with the nutritional benefits it needs, walnuts are linked to a reduction in inflammation. They contain polyphenols, which are micronutrients that have several health benefits.

The polyphenols in walnuts can be converted to compounds called urolithins within the gut. These compounds have been found to help reduce inflammation in the body.
