10. High-Fiber Foods
Whole grains, fruits, vegetables, and legumes all provide fiber, and are generally healthy foods. However, as mentioned earlier, foods that are high in fiber can also cause problems for people with thyroid issues. While normally healthy, high-fiber foods can cause interference with thyroid medication by limiting your body’s ability to absorb thyroid replacement hormones. If you can, limit your fiber intake to somewhere between 20 and 30 grams each day. If you’re stuck on a high fiber diet, you may need to increase your medication dosage. This is an important conversation to have with your doctor.
If you suffer from hyperthyroidism, you may want to cut down on your coffee intake, as having a lot of caffeine, especially early in the morning, can cause problems. Taking your thyroid medication with coffee in the morning leads to out of control thyroid levels, so it’s best to avoid using anything other than water to take your medication. Furthermore, if you just can’t get away from having that morning coffee, make sure to wait at least half an hour after taking your medication before having coffee.
8. Processed Foods
Much like fatty and sugary foods, processed foods can prove very unhealthy if eaten in excess. Oftentimes, they have a number of harmful ingredients, and are notably high in added salt. Too much sodium can raise blood pressure, as it causes the blood vessels to stiffen; worse, obesity, heart disease, and diabetes tend to exacerbate each other. For the person with an underactive thyroid, this is all very problematic, because those with hypothyroidism are already in danger of having high blood pressure. Too much added salt increases this risk. The American Heart Association recommends that such individuals should keep their salt intake below 1500 milligrams a day.Related: 7 Natural Ways to Lower Blood Pressure
