Thyroid Health and The Coconut Diet

Many Americans suffer from symptoms such as cold hands and feet, low body temperature, sensitivity to cold, a feeling of always being chilled, headaches, insomnia, dry skin, puffy eyes, hair loss, brittle nails, joint aches, constipation, mental dullness, fatigue, frequent infections, hoarse voice, ringing in the ears, dizziness, loss of libido, and weight gain, which is sometimes uncontrollable. Approximately 65 percent of the U. S. population is overweight; 30 percent is clinically obese. Research is pointing to the fact that an under active thyroid might be the number one cause of weight problems, especially among women, in the US today.

While more research needs to be done, it is generally accepted that diet plays a major role in thyroid health.  For decades we have known that low iodine intake leads to low thyroid function and eventually to goiter.  Iodized salt was intended to solve this problem, but it has not been the answer.  There are a number of foods known as goitrogens that block iodine. Two goitrogens are quite prevalent in the American diet—peanuts and peanut butter and soybeans used most often in prepared foods as textured vegetable protein (a refined soy food) and soybean oil.
