New research has found that women who eat walnuts every week can age better, becoming more active and independent later in life.
Researchers studies data from more than 50,000 nurses over 30 years, eating around a dozen walnut halves once or twice every week.
It was noted that these women became less frail than those who did not consume walnuts on a regular basis.
Walnuts are a great source of omega-3 essential fatty acids and are also a rich source of energy.
It was also found that a higher intake of fruits and vegetables and less intake of sugary beverages, sodium and trans-fats helped in reducing the rate of physical impairment.
