What is soy lecithin and why is it in everything?
What is soy lecithin? Lecithin is a food additive that comes from several sources — one of them being soy. It’s generally used as an emulsifier, or lubricant, when added to food, but also has uses as an antioxidant and flavor protector. Like many food additives, soy lecithin isn’t without controversy.
Does soy lecithin affect thyroid?
Thus, collectively the findings provide little evidence that in euthyroid, iodine-replete individuals, soy foods, or isoflavones adversely affect thyroid function. In contrast, some evidence suggests that soy foods, by inhibiting absorption, may increase the dose of thyroid hormone required by hypothyroid patients.
Why is soy bad for thyroid?
Animal studies dating back as far as 1959 have suggested that certain chemical components of soy — the isoflavones — may be linked to thyroid disorders, especially goiter and low thyroid. The two main soy isoflavones, genistein and daidzein, inhibit thyroid peroxidase, an enzyme necessary for making thyroid hormone.
Is soy not good for thyroid?
Hypothyroidism is generally treated with synthetic thyroid hormone — and soy has long been thought to interfere with the body’s ability to absorb the medication. However, there’s no evidence that people who have hypothyroidism should avoid soy completely.
What are the side effects of soy lecithin?
Although not all side effects are known, lecithin is thought to be likely safe for most people. Common side effects may include: diarrhea, nausea, stomach pain or fullness.
Does soy lecithin increase estrogen?
Furthermore, we found soy lecithin to be strongly estrogenic. It might, therefore, be a major contributor to total estrogenicity. We conclude that dietary estrogens are omnipresent and not limited to soy-based food.
Does soy lecithin decrease testosterone?
No. Soy intake does not raise or lower a man’s testosterone levels. Derived from soybeans, soy is a high-protein substance found in many foods, such as edamame, tofu, tempeh, miso, soy flour, and soy milk.
Is it safe to take lecithin everyday?
It is important to remember that there is no recommended daily intake of lecithin and that you will likely get enough by eating a balanced diet high in green vegetables, legumes, and healthy fats.
