Dr. Fuhrman mentions in Eat to Live that soy products such as soy burgers, soymilk, and soy cheeses have grown in popularity, resulting in their widespread availability. Despite the positives of soy consumption, many people harbor worries over the bean. In the member center of DrFuhrman.com he talks with a few concerned members:
I.Forum Member: Please give me some advice and direction concerning the use of soy milk, my physician is very upset with me that I started using soymilk, he states it is very dangerous and can cause many thyroid and autoimmune diseases, please clear this up for me, I am a 46 year old female who has had an hysterectomy and do not take any estrogen replacement.
Dr. Fuhrman: Is your physician a real doctor? Or does he just play one on TV? Before you accept a dramatic and radical claim about the dangers of soymilk, you should ask this person to show you some scientific medical journal articles that support his assertion.
Bottom line, there is evidence that substituting soy formula for breast milk has long-term harmful consequences, but no data to suggest that consuming soy milk as an adult has any negative health consequences as he claims. Keep the soymilk and get rid of the doctor.
II.Forum Member: Should men with prostate problems (enlarged) or women who want to avoid breast cancer take ground flaxseeds? I read something about flaxseed oil and estrogen. Also, can soymilk be safely taken, or do soy products contain estrogen that may promote breast cancer?
Dr. Fuhrman: Of course. All people should regularly use some ground flax or hemp seeds, but not the oil. Soy does not promote breast cancer. In fact, research shows it has protective effects. This has been answered in depth with references on this forum in the past. Did you try to do a search for it?
That does not mean I recommend processed soy products or soy powders. It means using some tofu, frozen soybeans or some soymilk in your diet is okay.
III.Forum Member: When I was diagnosed with an under active thyroid and began meds, I was told to stay away from soy products. I have much difficulty getting my body to lose weight and I attribute this to slow metabolism from the thyroid condition. Can you give me some information about soy and how it reacts with thyroid medications?
Dr. Fuhrman: I can assure you that eating some soy beans or tofu as part of a well-rounded diet will have zero effect on your thyroid gland. It is true that being raised on soy formula instead of breast milk as an infant increases your risk of hypothyroidism later in life, but this does not mean that eating some soy products causes thyroid problems.
