Can food help avoid the disease get worse?

Hi everybody, I'm just discovered Hashimoto Thyroiditis. I'm at the beginning, with no symptoms ad a good TSH range. For now I don't have to take any meds, but I will if I'll get worse TSH results.

Anybody can tell me if there is a food diet that can help thyroid working better and maintain my TSH range?

Thank you all for the support :)
