Onions cannot be eaten with apples, as they may induce thyroid enlargement?

It is April now, and onion season has arrived. However, a rumor has gone viral on the Internet: "Onions cannot be eaten with apples or carrots. They may induce goiter?" Nutritionists point out that this is a wrong statement. Onions are rich in nutrients and are known as the "Queen of Vegetables." They will not cause goiter just by eating them with apples or carrots.

It is not only a good food for weight loss, but also contains polyphenols that can prevent cancer. It has the effect of lowering blood lipids and stabilizing blood sugar levels, making it very suitable for diabetic patients.

Can’t onions be eaten with apples or carrots?

Regarding "Can't onions be eaten with apples or carrots?" It is mainly due to the misunderstanding that onions will produce sulfides through metabolism, while apples and carrots are rich in bioflavonoids, which are natural antioxidants. They are easily decomposed by bacteria in the intestines and converted into benzoic acid and ferulic acid, which will enhance the inhibitory effect of thiocyanate on the thyroid gland.

In fact, the causes of thyroid enlargement may be thyroid hypoplasia, thyroid tissue destruction, thyroid hormone synthesis disorders, etc. Different foods contain different nutrients. Eating only one food or adding another food together will not suppress the function of the thyroid gland. The correct way is to consume all kinds of food in a balanced way.
