Quantification of lectins in Synsepalum dulcificum and comparison with reference foods

Abstract

A healthy life means a balance between physical activity and a diet rich in fruits and vegetables, however, some plant-based foods can have certain adverse effects due to the presence of anti-nutritional factors, such as lectins, capable of binding molecules and preventing their normal assimilation. The level of lectins in Synsepalum dulcificum fruit was determined by hemagglutination assays in human blood, and its comparison with foods characterized as having high and low lectin content. The relative hemagglutinating activity of berries from Synsepalum dulcificum compared to our positive high lectin content food reference (Pinto bean) corresponds to 3.13-6.25%, representing safe levels for nutritional food.
