Q: ... is hyper/hyopthyroidism common at any age? Or is there any lifestyle that will increase the risk of getting them? -Sakinah

Overworking is a lifestyle that will increase the risk of getting the disorders.

Q: ... A question since this really bothered me. Do you think by drinking coffee everyday, it would increase the chance of having this disorder? So would you say the food cause the disorder? or it really just depends on individual? -Lynn

If you do not suffer from either of the disorders, it's fine to drink coffee everyday. The foods proposed for thyroid health are mainly advise for those with the disorders. This is because many of them are unaware that when taking medication in the morning, they aren't suppose to consume caffeine within an hour from taking their medication.
Food does not cause the disorder however, do take note on balance and moderation. One of the functions of the thyroid gland is to destroy toxins from fish, eggs, cheese and so on but when too much is consumed, it puts strain on the gland. Other factors such as overworking will increase the chance of having this disorder.
Ultimately, it depends on an individual's thyroid gland limits.
