Beetroot juice increases the risk of thyroid nodules and hypothyroidism in breast cancer patients
A
fter diagnosis, many breast cancer patients start consuming high quantities of beetroot and carrot juice in the hope that
it will sustain their treatment. But these foods are very high in nitrates which can competitively inhibit the use of iodine
by the thyroid, potentially leading to hypothyroidism or thyroid nodules. Thus, we applied a nitrate and iodine food frequency
questionnaire (asking about dairy, fish, sea food and iodized salt for iodine intake and spinach, carrots, beetroot, lettuce and
arugula for nitrates intake) to 353 ER+/PR±/HER2- breast cancer patients during anti-estrogenic treatment. We excluded
patients with a thyroid disease diagnosis before the cancer diagnosis, ex-smokers or those with renal disease or bipolar
disorders. In this sample of patients, the only correlations between dietary intake of nitrates and the appearance of thyroid
nodules were protection factor by minimum intake of dairies 250 ml/day; risk factor by intake over 200 g spinach, 250 g carrots
or beetroot 250 g/day. And the correlations between dietary intake of nitrates and hypothyroidism were protection factor by
intake of iodized salt 2.5 g, minimum fish 100 g or 250 ml dairy/day; and risk factor by intake over 250 g carrots or beetroot 250
g/day. The results of this study support the hypothesis that an increased intake of foods high in nitrate - in particular beetroot
and carrot juice-is a risk factor for the
de novo
development of hypothyroidism or thyroid nodules after the diagnosis of breast
cancer.
