Food Intake before and after Gastroplasty for Morbid Obesity

Abstract

Preoperatively, the energy intake was high, the protein intake was sufficient, whereas the relative contribution of fat was greater than and of carbohydrate less than the recommended values. After gastroplasty a dramatic fall occurred in the intake of energy and all nutrients, and a relative reduction in the contribution of fat at 3 months and of carbohydrate at 12 months was observed. Preoperatively, the intake of vitamins D, B₆, folacin, biotin, magnesium, iron, zinc, manganese, copper, and fluoride was deficient. Twelve months after operation the intake of these components and of vitamin E and iodine was less than half of the values recommended.
