RESUMEN
BACKGROUND & AIMS: To our knowledge the association between dietary advanced glycation end-products (dAGEs) and cardiometabolic disease is limited. Our aim was to examine the association between dAGEs and serum concentration of carboxymethyl-lysine (CML) or soluble receptor advanced glycation end-products (sRAGEs), and to assess the difference on dAGEs and circulating AGEs according to lifestyle and biochemical measures. METHODS AND RESULTS: 52 overweight or obese adults diagnosed with type 2 diabetes were included in this cross-sectional analysis. dAGEs were estimated from a Food Frequency Questionnaire (FFQ) or from a FFQ + Home Cooking Frequency Questionnaire (HCFQ). Serum concentrations of CML and sRAGEs were measured by ELISA. Correlation tests were used to analyze the association between dAGEs derived from the FFQ or FFQ + HCFQ and concentrations of CML or sRAGEs. Demographic characteristics, lifestyle factors and biochemical measures were analyzed according to sRAGEs and dAGEs using student t-test and ANCOVA. A significant inverse association was found between serum sRAGEs and dAGEs estimated using the FFQ + HCFQ (r = -0.36, p = 0.010), whereas no association was found for dAGEs derived from the FFQ alone. No association was observed between CML and dAGEs. dAGEs intake estimated from the FFQ + HCFQ was significantly higher among younger and male participants, and in those with higher BMI, higher Hb1Ac levels, longer time with type 2 diabetes, lower adherence to Mediterranean diet, and higher use of culinary techniques that generate more AGEs (all p values p < 0.05). CONCLUSIONS: These results show knowledge on culinary techniques is relevant to derive the association between dAGEs intake and cardiometabolic risk factors.

Culinary medicine (CM) represents a novel strategy to promote healthy ageing, as it improves adherence to healthy dietary patterns by providing nutritional education and training in cooking skills. We conducted a comprehensive review of the current scientific literature (2011-2022) concerning CM programmes implemented among participants over the age of 40. This review includes fourteen culinary-nutritional interventions. Each CM programme was analysed according to seven variables: health goal, study design, theoretical basis of the intervention, intervention duration, main outcomes, culinary intervention and the effectiveness of intervention. Although CM programmes showed low effectiveness in achieving positive results on psychosocial outcomes, they were successful in improving dietary intake and health-related outcomes. The interventions lasting for at least 5 months and employing study designs with two or more groups seemed to be important factors associated with achieving significant results. Significant results were observed regardless of the prevention phase defined as the health objective of the CM programme. The use of theoretical frameworks as an educational resource did not influence the effectiveness of the interventions. Other variables such as the inclusion of culinary outcomes, the optimisation of the culinary curriculum taught to the participants and the participation of a chef in the intervention are factors that should be taken into account. In addition, several educational components (cooking classes, hands-on cooking, free food delivery, individualized counselling) were promising for achieving health outcomes in ageing people. Our review has shown that CM programmes can be a powerful tool to improve the health status of ageing people.
RESUMEN
BACKGROUND: The bioaccessibility of bioactive compounds for functional food deserves evaluation. An in vitro gastrointestinal digestion model was applied to provide information about the extent of lipid hydrolysis, oxidative stability and bioaccessibility of algae oil (42% of docosahexaenoic acid; DHA), comparing three lipid delivery systems: bulk oil, soy protein stabilized O/W emulsion and carrageenan gelled emulsion. RESULTS: Lipid digestion kinetics was slightly influenced by the delivery systems. Nevertheless, at the end of intestinal digestion, lipolysis in the three samples ranged between 49% and 52%, showing a partial oil digestion. Lipid oxidation, measured by malondialdehyde, was significantly lower (P < 0.01) in both emulsified oils after intestinal digestion compared to the bulk oil. Bioaccessibility of DHA was 58%, 71% and 84% for bulk oil, O/W emulsion and gelled emulsion, respectively. CONCLUSION: These results suggest that both emulsified delivery systems used in the present study enhanced the solubilization of free fatty acids, in particular omega-3 fatty acids, and therefore their potential intestinal absorption. © 2018 Society of Chemical Industry.

Gelled emulsions with carrageenan are a novel type of emulsion that could be used as a carrier of unsaturated fatty acids in functional foods formulations. Lipid degradation through volatile compounds was studied in gelled emulsions which were high in polyunsaturated oils (sunflower or algae oil) after 49 days of storage. Aqueous Lavandula latifolia extract was tested as a natural antioxidant. Analysis of the complete volatile profile of the samples resulted in a total of 40 compounds, classified in alkanes, alkenes, aldehydes, ketones, acids, alcohols, furans, terpenes and aromatic hydrocarbons. During storage, the formation of the volatile compounds was mostly related to the oxidation of the main fatty acids of the sunflower oil (linolenic acid) and the algae oil (docosahexaenoic acid). Despite the antioxidant capacity shown by the L. latifolia extract, its influence in the oxidative stability in terms of total volatiles was only noticed in sunflower oil gels (p < 0.05), where a significant decrease in the aldehydes fraction was found.
RESUMEN
Dietary interventions are a key strategy to promote healthy ageing. Cooking skills training emerges as a promising approach to acquiring and maintaining healthy eating habits. The purpose was to evaluate the effectiveness of a culinary programme to improve healthy eating habits among overweight/obese adults (55-70 years old). A total of 62 volunteers were randomly (1:1) assigned to an culinary intervention group (CIG) or a nutritional intervention group (NIG). Dietary, cooking, and health-related outcomes, including body advanced glycation end product (AGE) levels, were evaluated at baseline and after four weeks. Mixed-effects linear models were used to assess the effects of the interventions within and between groups. Among the 56 participants who completed the trial, CIG participants achieved a significant improvement in Mediterranean diet adherence (1.2; 95%CI, 0.2 to 2.2) and a reduction in the use of culinary techniques associated with a higher AGE formation in foods (-2.8; 95%CI, -5.6 to -0.2), weight (-1.5; 95%CI, -2.5 to -0.5), body mass index (-0.5; 95%CI, -0.8 to -0.2), waist circumference (-1.4; 95%CI, -2.6 to -0.2), and hip circumference (-1.4; 95%CI, -2.4 to -0.4) compared with the NIG participants. Although a greater confidence in cooking in the CIG was found, attitudes and cooking habits did not improve. No significant differences in biochemical parameters or AGEs were found between groups. In conclusion, a culinary intervention could be successful in promoting healthy eating and cooking habits compared to a programme based on nutrition education alone. Nevertheless, further efforts are needed to strengthen attitudes and beliefs about home cooking, to address potential barriers and understand the impact of cooking interventions on biological parameters. Larger studies with longer follow-ups are needed to evaluate the relationship between cooking, diet, and health.

Background: Irritable bowel syndrome is a heterogeneous syndrome and it is difficult to find an effective treatment. Previously, a starch- and sucrose-reduced diet (SSRD) demonstrated promising short-term outcomes. It was proposed that genetic variants in the sucrose-isomaltase gene might influence this success. Our aim in this work was to extend the follow-up study to 1 year and to analyse the effect of the genetic variants of genes involved in starch and sucrose metabolism. Methods: IBS-SSS questionnaire, IBS-QoL questionnaire and questionnaires about adherence, difficulty and food assessment were sent to 34 patients after 6 months and 1 year after the end of the dietary intervention. In addition, 11 genes involved in sucrose and starch metabolism were sequenced. Results: Twenty-three participants responded to the 6 months follow-up and 16 to the 1 year follow-up. IBS-SSS total value increased 59.71% in the 6 months follow-up compared with the end of the intervention (p = 0.0018), and 55.39% in the 1 year follow-up (p = 0.0166); while IBS-QoL score decreased 24.09% (p = 0.0002) and 18.07% (p = 0.0022), respectively. The adherence decreased by 29.11% (p = 4.8 × 10-5) and 27.21% (p = 0.0054), respectively. In addition, carriers of pathogenic variants on the SI gene showed a slightly better performance than non-carriers. Finally, the participants showed less satisfaction over time with 18 allowed foods in the diet. Conclusion: Over time the SSRD is difficult to follow and the genotype might affect the performance of the diet. Since this diet could be a promising therapeutic option, a larger cohort needs to be analysed to validate the results and to compare it with other diets.
RESUMEN
Background: Irritable bowel syndrome (IBS) is a common gastrointestinal condition which entails a high burden in the quality of life (QoL) of patients. Nutritional interventions have been proposed to alleviate symptoms, since still no effective treatments exist for IBS. Objectives: Our aim is to analyse the feasibility of the use of starch- and sucrose-reduced diet (SSRD). Design: In this study, we used a SSRD accompanied by nutritional and culinary recommendations to measure the effects in IBS patients with diarrhoea. Methods: In all, 34 participants completed a 4-week nutritional intervention based on SSRD. Symptoms, QoL and dietary habits were assessed by several questionnaires that were completed at the beginning, daily, after 2 weeks, at the end, and after 2 months. Results: 85.29% of the participants reached the primary endpoint [reduction of 50 points or more in IBS-symptom severity scale (SSS)], and 58.82% the secondary endpoint (reduction of 50% or more in IBS-SSS). The relief of symptoms and improvement of the QoL were significant after 2 weeks of intervention, at the end and after 2 months. Dietary habits were consistent with the diet and high adherence was achieved. Conclusions: SSRD and individualized nutritional and culinary guidance improved symptoms and QoL of IBS patients with diarrhoea, with a high adherence.
RESUMEN
BACKGROUND: The objectives of this pilot study were to evaluate the safety and efficacy of the central nervous system stimulant methylphenidate in the management of asthenia in breast cancer patients treated with docetaxel. PATIENTS AND METHODS: Patients with early breast cancer who presented asthenia >3 on the Visual Analogue Scale (VAS) after the first cycle of docetaxel-based chemotherapy were included. Patients received two additional cycles of chemotherapy, one with methylphenidate (10 mg bid) and the other without methylphenidate. Asthenia was evaluated using VAS and the Functional Assessment of Cancer Therapy-Fatigue (FACT-F) scale. Distress was assessed using the Hospital Anxiety and Depression Scale (HADS), and quality of life using FACT-F. RESULTS: Ten patients were included and evaluated for efficacy and safety. Overall, cycles with methylphenidate were better tolerated than those without methylphenidate in terms of asthenia (VAS, p = 0.004; FACT-F, p = 0.027) and quality of life (FACT-F, p = 0.047). No significant differences were observed in terms of distress (HADS, p = 0.297). Six (60%) patients continued with methylphenidate after study end. Main adverse events during study were palpitations and insomnia (30% of patients each). CONCLUSIONS: This pilot study suggests that methylphenidate may reduce asthenia and improve quality of life in breast cancer patients treated with docetaxel.

Home cooking and the type of cooking techniques can have an effect on our health. However, as far as we know, there is no questionnaire that measures in depth the frequency and type of cooking techniques used at home. Our aim was to design a new Home Cooking Frequency Questionnaire (HCFQ) and to preliminarily assess its psychometric properties. For this purpose we used a five-phase approach, as follows: Phase 1: item generation based on expert opinion, relevant literature and previous surveys; Phase 2: content validity assessed by experts for relevance and clarity (epidemiologists, dietitians, chefs); Phase 3: face validity and inter-item reliability; Phase 4: criterion validity using a 7-day food and culinary record; and Phase 5: test stability and inter-item reliability. The content validity index for scale and item level values provided evidence of the content validity for relevance and clarity. Criterion validity analysis showed intraclass correlation coefficients ranged from 0.31−0.69. Test−retest reliability coefficients ranged from 0.49−0.92, with Æ values > 0.44. Overall Cronbach's alpha was 0.90. In conclusion, the HCFQ is a promising tool with sound content and face validity, substantial criterion validity, and adequate reliability. This 174-item HCFQ is the first questionnaire to assess how often people cook and which cooking methods they use at home.

Non-communicable diseases (NCDs) are the first causes of death worldwide. Reduction in the dietary intake of salt and sugars is important lifestyle advice that is useful for NCD prevention. However, the simple recommendations of reducing salt and sugars by healthcare professionals are often ineffective; innovative strategies are therefore necessary. This review aimed at describing the current knowledge about the strategies to reduce dietary salt and sugar intake, including both strategies for the food industry to reduce the salt or sugar of its products and recommendations for health professionals in a clinical context, such as the replacement with substitutes in foods, the gradual reduction to allow a progressive consumer adaptation towards less intense taste, and the different spatial distribution of tastants within the food matrix with taste intensity enhancement. In addition, the cross-modal interaction between two or more different sensory modalities as an innovative strategy for enhancing sweetness and saltiness perception was described. Finally, the dietary tips for salt and sugar reduction were summarized in order to create a comprehensive guide of dietary advices for healthcare professionals for optimizing the management of patients at increased cardiometabolic risk.

FGF21 has emerged as a key metabolism and energy homeostasis regulator. Dietary supplementation with eicosapentaenoic acid (EPA) and/or α-lipoic acid (LIP) has shown beneficial effects on obesity. In this study, we evaluated EPA and/or LIP effects on plasma FGF21 and the fatty acid (FA) profile in overweight/obese women following hypocaloric diets. At the baseline, FGF21 levels were negatively related to the AST/ALT ratio and HMW adiponectin. The weight loss did not cause any significant changes in FGF21 levels, but after the intervention FGF21 increased in EPA-supplemented groups compared to non-EPA-supplemented groups. EPA supplementation decreased the plasma n-6-PUFA content and increased n-3-PUFAs, mainly EPA and DPA, but not DHA. In the LIP-alone supplemented group a decrease in the total SFA and n-6-PUFA content was observed after the supplementation. Furthermore, EPA affected the desaturase activity, lowering Δ4D and raising Δ5/6D. These effects were not observed in the LIP-supplemented groups. Besides, the changes in FGF21 levels were associated with the changes in EPA, n-3-PUFAs, Δ5/6D, and n-6/n-3 PUFA ratio. Altogether, our study suggests that n-3-PUFAs influence FGF21 levels in obesity, although the specific mechanisms implicated remain to be elucidated.
