An Unexpected Ally for Eye Health
Soy has long been recognized for its protein content and cardiovascular benefits — but newer research is revealing another reason to add it to your diet: protection for your eyes.
The Isoflavone Connection
Soy foods are rich in isoflavones — compounds with powerful antioxidant properties. Research shows that soy isoflavones protect against cataract formation in animal studies, and scientists believe similar benefits may extend to humans.
The best soy sources for eye health include:
- Soy milk
- Soy sauce
- Miso
- Tempeh
- Tofu (a natural addition to this list)
- Edamame
Soy and Dry Eye Syndrome
There’s another eye condition where soy may play a helpful role: dry eye syndrome. A 2010 study found that isoflavones from soy may help restore tear production that has been reduced by this common and often frustrating condition.
Dry eye affects millions of people — particularly postmenopausal women — and can significantly impact quality of life. If you struggle with dry, irritated eyes, adding more soy to your diet may be worth discussing with your eye doctor.
Easy Ways to Eat More Soy
- Swap regular milk for soy milk in your morning coffee or cereal
- Use miso paste as a base for soups and dressings
- Snack on edamame sprinkled with sea salt
- Use tempeh in stir-fries or grain bowls as a protein source
- Try sesame and soy-roasted fall vegetables as a flavorful side dish
