Kohlrabi is rich in nutrients such as vitamin C, potassium, fiber, and antioxidant compounds. However, for people with thyroid disease, eating kohlrabi can cause some negative effects if not used properly. This is because kohlrabi contains a group of compounds called goitrogens, which can affect the functioning of the thyroid gland.
Goitrogens and their effects on the thyroid gland
Goitrogens are compounds that inhibit the synthesis of thyroid hormones by preventing the body from using iodine, an important trace element in the production of thyroid hormones. When there is a deficiency of thyroid hormones, the body can experience problems such as hypothyroidism, with symptoms such as fatigue, weight gain, and depression. Studies from the World Health Organization and thyroid disease experts recommend that people with thyroid disease pay attention to the consumption of foods containing goitrogens, especially when they are eaten raw.
Some cruciferous vegetables, including kohlrabi, contain goitrogenic compounds such as glucosinolates, which can interfere with thyroid function if consumed in excess, especially in people with an already weakened thyroid condition. However, cooking kohlrabi can help reduce the effects of goitrogens, as high temperatures can break down their structure, minimizing their harmful effects on the thyroid.
Recommendations for people with thyroid disease
According to nutritionists from the US National Institutes of Health, people with thyroid disease can eat kohlrabi, but they should note a few important points. First, do not eat too much raw kohlrabi or other cruciferous vegetables that contain goitrogens. Second, cooking kohlrabi by boiling or steaming will help reduce the effects of these compounds. Third, patients also need to ensure that they get enough iodine in their diet to support thyroid function.
Although kohlrabi is a nutritious food, people with thyroid disease should carefully control the consumption of kohlrabi. A reasonable diet, combined with cooking kohlrabi, will help minimize the negative effects of goitrogens on thyroid health. Before changing the diet, people with thyroid disease should consult a doctor or nutritionist for a suitable nutritional plan.
