Low Mineral Intake in the Gluten-Free Diet?

Elisabeth Hasselbeck - Gluten-Free
The Gluten-Free diet, a medical necessity for those with Celiac Disease, is gaining popularity among the general population.  In part, this trend has been fueled by the popularity and support of the gluten-free diet among celebrities such as Victoria Beckham (Posh Spice), Zooey Deschanel, and The View's Elisabeth Hasselbeck, for example.

On a cautionary note, a research study from the UK suggests that the gluten-free diet may be deficient in some important minerals and dietary fiber [1].

From the study authors:
Individuals consuming a strict GFD (gluten-free diet) generally had similar intakes of energy and nutrients to those of comparison populations, but a higher proportion of carbohydrate intake was obtained from nonmilk extrinsic sugars and intakes of nonstarch polysaccharides were low. Compared with the UKWCS sample, female patients adhering to a GFD had lower intakes of magnesium, iron, zinc, manganese, selenium and folate. In male patients, intakes of magnesium and selenium were particularly low.

Summary:

The study authors found that the gluten free diet was high in sugar, low in minerals such as iron, zinc, manganese, selenium, magnesium, and folate, and low in dietary fiber.
