In the story of the woman who ate cabbage daily for a month and felt unwell, the likely explanation is a combination of factors:

High Goitrogen Intake: A massive, daily intake of raw cabbage could have suppressed thyroid function, leading to symptoms like fatigue and joint discomfort.

Underlying Deficiency: She may have had a pre-existing, mild iodine deficiency that was exacerbated by her new diet.

This story is a powerful reminder that even “superfoods” are best consumed as part of a balanced and varied diet.
