BACKGROUND A smartphone image recognition application is expected to be a novel tool to measure nutrients and food intake, but its performance has not been well evaluated. OBJECTIVE We assessed the performance of an image recognition application called CALO mama in terms of the nutrient and food group contents automatically estimated by the application. METHODS We prepared 120 sample meals for which the nutrients and food groups were already calculated. Next, we predicted the nutrients and food groups included in the meals from their photographs using 1) automated image recognition only and 2) manual modification after automatic identification. RESULTS Predictions using only image recognition were similar to the actual data in weight of meals, 11 out of 30 nutrients, and 4 out of 15 food groups; it underestimated energy, 19 nutrients, and 9 food groups; it overestimated dairy products and confectioneries. After manual modification, predictions were similar in energy, 29 out of 30 nutrients, and 10 out of 15 food groups; it underestimated pulses, fruits, and meats; it overestimated weight, vitamin C, vegetables, and confectioneries. CONCLUSIONS The results of this study suggest that manual modification after prediction using image recognition improves the performance of the assessment of nutrients and food intake. Our findings suggest the potential of image recognition to achieve a description of the dietary intakes of populations using “precision nutrition” (a comprehensive and dynamic approach to develop tailored nutritional recommendations) for individuals.

Abstract Obesity and increased body adiposity have been alarmingly increasing over the past decades and have been linked to a rise in food intake. Many dietary restrictive approaches aiming at reducing weight have resulted in contradictory results. Additionally, some policies to reduce sugar or fat intake were not able to decrease the surge of obesity. This suggests that food intake is controlled by a physiological mechanism and that any behavioural change only leads to a short-term success. Several hypotheses have been postulated, and many of them have been rejected due to some limitations and exceptions. The present review aims at presenting a new theory behind the regulation of energy intake, therefore providing an eye-opening field for energy balance and a potential strategy for obesity management.

Abstract. Emotion-related impulsivity, defined as the tendency to say or do things that one later regret during periods of heightened emotion, has been tied to a broad range of psychopathologies. Previous work has suggested that emotion-related impulsivity is tied to an impaired function of the serotonergic system. Central serotonin synthesis relies on the intake of the essential amino acid, tryptophan and its ability to pass through the blood brain barrier. Objective: The aim of this study was to determine the association between emotion-related impulsivity and tryptophan intake. Methods: Undergraduate participants (N = 25, 16 women, 9 men) completed a self-rated measure of impulsivity (Three Factor Impulsivity Index, TFI) and daily logs of their food intake and exercise. These data were coded using the software NutriNote to evaluate intakes of tryptophan, large neutral amino acids, vitamins B6/B12, and exercise. Results: Correlational analyses indicated that higher tryptophan intake was associated with significantly lower scores on two out of three subscales of the TFI, Pervasive Influence of Feelings scores r =  –.502, p < . 010, and (lack-of) Follow-Through scores, r =  –.407, p < . 050. Conclusion: Findings provide further evidence that emotion-related impulsivity is correlated to serotonergic indices, even when considering only food habits. It also suggests the need for more research on whether tryptophan supplements might be beneficial for impulsive persons suffering from a psychological disorder.
