According to studies published in medical journals such as The New England Journal of Medicine, people who eat walnuts 3–5 times a week have up to a 30% lower risk of cardiovascular disease. The reason is their rich content of omega-3 fatty acids, which maintain the flexibility of blood vessels and regulate levels of “bad” cholesterol.
Walnuts are also one of the best natural sources of antioxidants that protect cells from damage. They contain vitamin E, polyphenols, and melatonin – substances that slow down aging and reduce inflammatory processes in the body.
One of the most notable benefits that doctors note is the influence of walnuts on brain function. It is no coincidence that the shape of the walnut itself resembles a human brain – it contains fatty acids, phosphorus and magnesium, which improve memory, concentration and nervous activity. Studies show that their regular consumption can reduce the risk of cognitive impairment and dementia in old age.
Additionally, walnuts aid digestion thanks to their fiber and create a feeling of satiety, making them useful for weight control. They also contain the amino acid arginine, which helps dilate blood vessels and improve blood circulation.
