New Study: The risks and benefits of soy

CHARLESTON, SC (WCSC) - Many women choose soy for their meals, rather than animal products, but a recent study finds women who eat a lot of soy products may face more problems with their thyroid function.

The study, conducted at Loma Linda University, found women who ate large amounts of soy-based food often experienced higher levels of serum thyroid-stimulating hormones (TSH.)

Experts say women are more at risk for thyroid disease than men, and may be more susceptible to factors that affect their thyroid function. This is especially true during perimenopause and menopause. Researchers say the women who are especially at risk are those who have a borderline underactive thyroid.

"This could suggest that women consuming high quantities of soy have an annual check on their TSH," Dr. Serena Tonstad, a lead researcher, said,

Experts say eating soy based foods can have benefits, including lowering LDL cholesterol levels. But the researchers caution there is concern that the isoflavones may adversely affect thyroid function.
