Any tips on thyroid health?

I just recently learned BOTH sides of my immediate family have various thyroid issues so I assume later in my life this will most likely trickle it’s way down to me. I’m 23 going to be 24 later this year, does anyone have any tips for thyroid health or to ensure it stays healthy for as long as possible?

And yes, I know I should consult a doctor for the best advice, but it’s 9:30 PM here and I’m just curious what any one else might have to say for the time being! 😄
