2. Packed with Antioxidants

These nuts are among the top foods with the highest antioxidant content. Walnuts contain compounds like vitamin E, melatonin, and polyphenols, which help combat oxidative stress — a major factor in aging and chronic diseases. By neutralizing free radicals, walnuts can protect your cells and support long-term health.

3. Supports Brain Function

It’s no coincidence that walnuts look like miniature brains. They’re loaded with nutrients known to promote brain health, including polyunsaturated fats, polyphenols, and vitamin E. Research suggests that walnut consumption may enhance memory, cognitive performance, and even mood — particularly in older adults.
