Eating walnuts from early age can keep your health in better condition at old age. 

Participants eating walnut in middle age tends to be physically active. 

The new findings appeared Thursday in the journal Nutrition, Metabolism and Cardiovascular Diseases.

"Walnut eaters seem to have a unique body phenotype that carries with it other positive impacts on health like better diet quality".

Walnuts "may act as a bridge or 'carrier food' for helping people form healthy nutrition and lifestyle habits throughout life," said Steffen

Walnut is an excellent source of Omega 3 Fatty Acid, which is good for health. 

1 ounce of serving walnuts have antioxidants like Polyphenols.

After 30 years, the walnut consumers had higher self-reported physical activity outcomes than people in the "other nut" and "no nut" categories. 

Walnuts have improved heart disease risk profile, waist circumference and lower body mass index.

The walnut eaters gained less weight over time.
