AskNadia: Is Soy Bad for Me?

Dear Nadia,

I have decided to start replacing some of my protein meals with soy. Is soy bad for me?

Portland Oregon

Dear Janet,

Soy is a high protein alternative that vegetarian and vegans use as a substitute for meat and dairy products. The origins of soy date back thousands of years from the Asian culture.

Plant-based foods are considered good for lowering your cholesterol and believe to have some benefits to a healthy heart in addition to strengthening bones. This is good news for people with osteoporosis.

Soy is also believed to lower blood sugars.

The two most common concerns with consuming soy products are the possible link to breast cancer and thyroid.

The Breast Cancer Link:

The research is mixed about breast cancer. Some say if you have a genetic disposition for breast cancer, you should err on the conservative side and not use soy in your diet.

Others argue that the benefit of soy for strengthening bones and a healthy heart outweighs the concern because the increased probability of getting a tumor is insignificant.

The Thyroid Link:

Many soy studies are based on consumption amounts that are unrealistic for the average person. There is no real evidence that soy benefits your thyroid or adversely impacts your thyroid. However, for people with iodine deficiency, soy can add to your deficiency. If you have hypothyroidism, soy may interfere with the medication that treats it.

Another well-designed study from the American Journal of Clinical Nutrition studied the effect of realistic amounts of soy protein on hormones, including thyroid hormone. It found that soy had no significant effects on these hormones.

Soy and Your Blood Sugars:

The Mayo Clinic reports that soy can decrease blood sugars. Caution is necessary for people who take oral medication or injectable medication to lower their blood sugars.

Reach out to your healthcare professional to discuss your consumption of soy and how it may impact your medications. There are other considerations for soy that include adverse reactions to certain medications. Including over the counter products like ibuprofen.
