A healthy diet is consistently touted as an essential part of any healthy life. But can eating healthy make you sick? Perhaps. After all, anything in excess -- even water -- can have a detrimental effect on your health.

As it turns out, eating too many fruits and veggies can aggravate thyroid disease, particularly goitrogenic foods like cauliflower, cabbage, broccoli, turnips and much more. These veggies can lead to a iodine deficiency, which can cause hypothyroid conditions get worse. Too many veggies have also shown to aggravate Irritable Bowel Syndrome, which I can attest to. Though in my case, I eat veggies regardless.

Unless you have one of these conditions, don't use this as an excuse to avoid your veggies. And if you do have one of these conditions, talk to your doctor.
