Soy Intake in Childhood Reduces Breast Cancer Risk Later in Life

A new study looking at more than 1,500 Asian-American women living in California

and Hawaii showed that those with the highest intake of soy during childhood

(younger than 12 years old) had a 60 percent lower risk of developing breast

cancer later in life. Regular soy consumption in adolescence (12 to 19 years

old) and adulthood (20 years old and older) also had a protective effect but

with 20 and 25 percent reductions in risk, respectively.1

Prior studies have shown similar protective effects of soy consumption before

adulthood.2,3,4
