Patients who have undergone bariatric surgery have increased risks of developing micronutrient deficiencies. Translational research investigating the actual micronutrient intake of bariatric patients is limited. We examined the micronutrient intake of a multicentre cohort of laparoscopic adjustable gastric banding patients 1 year post-surgery. These data were compared to micronutrient recommendations for the general population.
Consecutive patients from three bariatric surgery facilities in Melbourne, Australia, were invited to participate 12 months post-operatively. A validated food frequency questionnaire was posted to 215 prospective participants.
Of the 52 participants, micronutrient intakes from food and fluids alone were below population recommendations for calcium, folate, magnesium, potassium, retinol equivalents, thiamin and vitamin E. Males did not meet the recommended intakes for zinc, and iron intakes in pre-menopausal women were insufficient. Intakes lower than recommended levels for these micronutrients suggest inadequate intake of foods from vegetable, dairy, lean meat (or alternatives) and wholegrains. Micronutrient intakes below recommended levels in this patient group can be further explained by their macronutrient intakes that suggested diets of poor nutrient density. Recommendations for supplementation in this group have wide variations, usually having been developed through the presence of clinical and biochemical deficiencies.
Nutritional supplementation should be more extensive in scope and dosage than is currently recommended by some professional guidelines. Further long-term studies are needed to explore both macro- and micronutrient intakes on the morbidity and mortality of this patient population.
