RESUMEN
OBJECTIVE: To use Google Trends to explore the trends of interest of the Spanish population regarding information related to different types of diets, focused on those that are popular and with evidence-based studies, over the last 10years. MATERIAL AND METHODS: The search trends referred to the terms «Mediterranean diet¼, «ketogenic diet¼, «low fat diet¼, «intermittent fasting¼ and «vegan diet¼ were analyzed. The relative search volumes (RSV) of the terms were compared. The direction of the trend was studied using the Spearman's correlation coefficient (SC). RESULTS: «Mediterranean diet¼ was the most widely searched term, with a median RSV of 16 (interquartile range [IQR] 6; range 8-100), though it exhibited a decreasing chronological trend (SC=-0.216). It was followed by «ketogenic diet¼, with an RSV of 8 (IQR 9; range 1-57); «vegan diet¼, with an RSV of 4 (IQR 5; range 0-16); «intermittent fasting¼, with an RSV of 2 (IQR 5; range 0-27), and «low fat diet¼, with an RSV of 1.16 (IQR 0; range 0-2). The term with the best correlation over time was «intermittent fasting¼ (SC=0.96), followed by «ketogenic diet¼ (SC=0.91) and «vegan diet¼ (SC=0.85). CONCLUSIONS: In Spain, the interest of the population in information about the Mediterranean diet is greater than for other diets. However, in recent years there has been a progressive increase in interest (measured as RSV) in other diets such as the ketogenic diet, vegan diet or intermittent fasting, and there has been a decrease in interest in the Mediterranean diet. The low fat diet does not generate interest in the Spanish population.

INTRODUCTION: Even though evidence is lacking, a low-fat diet has been traditionally recommended after cholecystectomy. The main aim of this study was to assess the potential correlation between postoperative symptoms and type of diet after cholecystectomy. METHODS: Symptoms were prospectively assessed by the Gastrointestinal Quality of Life Index (GIQLI) score at baseline, one month and 6 months after cholecystectomy in 83 patients operated on at our institution. Patients completed a questionnaire about their diet and were classified into 4 groups according to the amount of fat intake. Differences in the GIQLI score depending on the type of diet were assessed over time. RESULTS: The overall GIQLI score and most subdomains significantly increased after surgery compared to baseline, regardless of the intake of dietary fat. Constipation improved after cholecystectomy compared to baseline, whereas diarrhea and bowel urgency got worse. More than 50% of patients experienced a change in their bowel habit after surgery, which persisted 6 months later in 23% of cases. CONCLUSIONS: A low fat diet does not seem to have an influence on the improvement of symptoms after cholecystectomy. However, a randomized study is ongoing at our institution to confirm the results of this prospective study.
