Phenolic compounds may exert a favorable effect on the risk of several cancer types, including gastric cancer (GC). However, selected polyphenol classes have not been adequately investigated in ...relation to GC. The aim of this study is to evaluate the association between the intake of polyphenols in relation to GC risk. We used data from the Stomach cancer Pooling (StoP) Project, including 10 studies from six countries (3471 GC cases and 8344 controls). We carried out an individual participant data pooled analysis using a two-stage approach. The summary odds ratios (ORs) of GC for each compound, and the corresponding 95% confidence intervals (95% CI), were computed by pooling study specific ORs obtained through multivariate logistic regression, using random effect models. Inverse associations with GC emerged for total polyphenols (OR = 0.67, 95% CI = 0.54–0.81, for the highest versus lowest quartile of intake), total flavonoids (OR = 0.73, 95% CI = 0.55–0.90), anthocyanidins (OR = 0.74, 95% CI = 0.56–0.92), flavanols (OR = 0.77, 95% CI = 0.66–0.88), flavanones (OR = 0.57, 95%CI = 0.44–0.69), total phenolic acids (OR = 0.75, 95%CI = 0.55–0.94), and hydroxybenzoic acids (OR = 0.73, 95%CI = 0.57–0.89). Results were consistent across strata of age, sex, social class, and smoking habit. Suggestive inverse associations were also found for flavonols (OR = 0.76, 95%CI = 0.51–1.01) and hydroxycinnamic acids (OR = 0.82, 95%CI = 0.58–1.06). Further investigations from longitudinal data are needed to confirm this association.
Dairy milk is a ubiquitous nutrient-dense beverage and ingredient, especially in Western diets. However, consumers are increasingly seeking alternatives to dairy, called plant-based milks (PBMs), to ...avoid allergens, pursue a plant-based diet, or reduce their environmental impacts. The base ingredients used in PBMs have a wide range of environmental impacts, which may translate to substantial variation across the impacts associated with PBMs themselves. To assess the state of the literature on this topic, we performed a scoping review of the environmental impacts of PBMs, following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. Recent growth in the variety of PBMs available means that there is unlikely yet enough data for conclusive statements regarding environmental impacts of all PBM types, which makes this topic appropriate for a scoping review. We included all relevant documents found through searching scholarly databases. We found 20 studies covering 6 types of PBMs, but the literature does not examine many other types of PBMs. All studies examined use the life cycle assessment methodology. The most data regarding environmental impacts were available for soy- and almond-based milks, and the most common impact quantified was greenhouse gas emissions. We also examined the nutrient composition of PBMs compared with dairy using data from the USDA. PBMs attempt to replicate the organoleptic properties of dairy but often do not exactly match the nutrient profile of dairy. We identified a need for the application of a standardized methodology to facilitate more comprehensive assessment of environmental impacts of the wide variety of PBMs available, which are presented as environmentally preferable to dairy.
El objetivo de este estudio es evaluar la asociación entre antecedentes familiares (AF) de primer grado y cáncer colorrectal (CCR).
Se incluyeron 2857 controles y 1360 casos de CCR, del estudio ...MCC-Spain. La odds ratio (OR) y el intervalo de confianza del 95% (IC95%) de los AF de primer grado y el CCR se estimaron mediante regresión logística no condicional según la localización tumoral en los casos.
Los AF de primer grado duplicaron el riesgo de CCR (OR: 2,19; IC95%: 1,80-2,66), incrementándose en aquellos que presentaban dos o más (OR: 4,22; IC95%: 2,29-7,78) y en aquellos cuyos familiares fueron diagnosticados antes de los 50 años (OR: 3,24; IC95%: 1,52-6,91). Presentar AF se relacionó con estilos de vida como un menor consumo de vegetales. En cuanto a la asociación de los AF con la localización no se observaron diferencias significativas entre colon y recto, pero sí en la relación de estas con la edad de diagnóstico, presentando más AF los diagnosticados antes de los 50 años (OR: 4,79; IC95%: 2,65-8,65).
Presentar AF de primer grado de CCR aumenta las probabilidades de desarrollar este cáncer, y también se elevan cuando el familiar es diagnosticado a edad temprana. Por ello, debe ser una población diana sobre la que incrementar las medidas de prevención.
To evaluate the association between first-degree family history and colorectal cancer (CRC).
We analyzed data from 2857 controls and 1360 CRC cases, collected in the MCC-Spain project. The adjusted odds ratio (OR) and 95% confidence interval (95% CI) of association with the family history of CRC was estimated by non-conditional logistic regression.
First-degree relatives doubled the risk of CRC (OR: 2.19; 95% CI: 1.80–2.66), increasing in those with two or more (OR: 4.22; 95% CI: 2.29–7.78) and in those whose relatives were diagnosed before 50 years (OR: 3.24; 95% CI: 1.52–6.91). Regarding the association of the family history with the location, no significant differences were observed between colon and rectum, but there were in the relation of these with the age of diagnosis, having more relatives those diagnosed before 50 years (OR: 4.79; 95% CI: 2.65–8.65).
First-degree relatives of CRC increase the chances of developing this tumor, they also increase when the relative is diagnosed at an early age. Therefore, it must be a target population on which to carry out prevention measures.
La cuantificación del riesgo cardiovascular se basa en puntuaciones como las de Framingham, Framingham-REGICOR, SCORE o Life's Simple 7 (LS7). Los polifenoles pueden proporcionar beneficios al ...sistema vascular y reducir la respuesta inflamatoria; sin embargo, los estudios clínico-epidemiológicos muestran resultados discordantes. Nuestro objetivo es evaluar la posible asociación entre la ingesta de diferentes clases de polifenoles y las puntuaciones cardiovasculares.
Estudio transversal sobre 6.633 participantes del estudio PREDIMED-Plus. El contenido de polifenoles se estimó mediante un cuestionario semicuantitativo de frecuencia alimentaria y se ajustó por la ingesta energética total según el método de residuales. La asociación entre la ingesta de polifenoles y el riesgo cardiovascular se evaluó mediante análisis de regresión lineal.
La ingesta total de polifenoles y flavonoides se asoció directa y significativamente con la escala LS7. Igualmente, los lignanos se asociaron directa y significativamente con las escalas SCORE y LS7; los estilbenos, con la SCORE y los ácidos fenólicos, con las de Framingham y Framingham-REGICOR. La clase «otros polifenoles» se asoció de manera significativa con las escalas de Framingham, SCORE y LS7. En las mujeres, la ingesta de todas las clases de polifenoles, excepto los ácidos fenólicos, mostró una tendencia directa en los resultados de Framingham y Framingham-REGICOR e indirecta con la escala LS7.
Se encontraron asociaciones inversas entre el consumo de la clase «otros polifenoles» y, especialmente en las mujeres, el riesgo cardiovascular estimado. Los resultados fueron similares con las de Framingham, Framingham-REGICOR y LS7 (después de eliminar el componente de dieta) y diferentes con la SCORE, pero los predictores que se incluyen en este son escasos.
Quantification of cardiovascular risk has been based on scores such as Framingham, Framingham-REGICOR, SCORE or Life's Simple 7 (LS7). In vitro, animal, and randomized clinical studies have shown that polyphenols may provide benefits to the vascular system and reduce the inflammatory response. However, some clinical-epidemiological studies have yielded inconsistent results. Our aim was to assess the possible association between intake of the various polyphenol classes and established cardiovascular scores.
This cross-sectional analysis involved 6633 PREDIMED-Plus study participants. Food polyphenol content was estimated by a semiquantitative food frequency questionnaire, adjusted for total energy intake according to the residual method. The association between polyphenol intake and cardiovascular risk was tested using linear regression analyses.
Total polyphenol and flavonoid intake were directly and significantly associated only with the LS7 scale. Intake of lignans was directly and significantly associated with SCORE and LS7 scales, stilbene intake with SCORE, and phenolic acid intake with Framingham and Framingham-REGICOR scores. Other polyphenol classes were associated in a protective and significant manner in Framingham, SCORE and LS7 scores. In women, intake of all the polyphenol classes, except phenolic acids, showed a protective trend in the results of the Framingham, Framingham-REGICOR scores and LS7 scale.
An inverse association was found between consumption of the ‘other polyphenols’ class and, especially among women, with estimated cardiovascular risk. The results were similar to those of Framingham, Framingham-REGICOR and LS7 (after eliminating the diet component) and differed from those of SCORE, but the predictors included were limited in the latter case.

Scope
Diets rich in polyphenols has been associated with better cognitive performance. The aim of this study is to assess the relationship between microbial phenolic metabolites (MPM) in urine and ...cognition in the context of an older population at high cardiovascular risk.
Methods and results
A cross‐sectional analysis is conducted in 400 individuals of the PREDIMED‐Plus study. Liquid chromatography coupled to mass spectrometry is used to identify urinary MPM. Mediterranean diet (MedDiet) adherence is estimated with a 17‐item questionnaire and cognitive function is evaluated with a battery of neuropsychological tests. Multivariable‐adjusted linear regression models are fitted to assess the relationship of urinary MPM with the MedDiet and cognitive tests. Protocatechuic acid and enterolactone glucuronide are associated with higher adherence to the MedDiet. Regarding cognitive function, protocatechuic acid, vanillic acid glucuronide, 3‐hydroxybenzoic acid, enterodiol glucuronide, and enterolactone glucuronide are directly associated with a global composite score of all the cognitive tests. Furthermore, protocatechuic acid and enterolactone glucuronide are associated with higher scores in the Mini‐Mental State Examination, whereas enterodiol glucuronide is associated with improved Clock Drawing Test scores.
Conclusions
These results suggest that the MedDiet is linked to MPM associated with better cognitive performance in an older population.
A cross‐sectional analysis is conducted in 400 individuals to assess the relationship between microbial phenolic metabolites and cognition in the context of a Mediterranean diet. Microbial phenolic metabolites are related to better global cognition, and protocatechuic acid and enterolactone glucuronide are associated with Mediterranean diet. This suggests that Mediterranean diet may promote microbial phenolic metabolites associated with better cognitive performance.
Several epidemiological studies have investigated the association between the dietary flavonoid intake and gastric cancer (GC) risk; however, the results remain inconclusive. Investigating the ...relationship between the different classes of flavonoids and the histological types and origin of GC can be of interest to the research community. We used data from a population-based multi-case control study (MCC-Spain) obtained from 12 different regions of Spain. 2700 controls and 329 GC cases were included in this study. Odds ratios (ORs) were calculated using the mixed effects logistic regression considering quartiles of flavonoid intakes and log2. Flavonoid intake was associated with a lower GC risk (ORlog2 = 0.76; 95% CI = 0.65-0.89; ORq4vsq1 = 0.60; 95%CI = 0.40-0.89; ptrend = 0.007). Inverse and statistically significant associations were observed with anthocyanidins, chalcones, dihydroflavonols and flavan-3-ols. The isoflavanoid intake was positively associated with higher cancer risk, but without reaching a statistical significance. In general, no differences were observed in the GC risk according to the location and histological type. The flavonoid intake seems to be a protective factor against GC within the MCC-study. This effect may vary depending on the flavonoid class but not by the histological type and location of the tumor. Broader studies with larger sample size and greater geographical variability are necessary.
Several anticancer properties have been largely attributed to phenolics in in vivo and in vitro studies, but epidemiologic evidence is still scarce. Furthermore, some classes have not been studied in ...relation to gastric cancer (GC). The aim of this study was to assess the relationship between the intake of phenolic acids, stilbenes, and other phenolics and the risk of developing GC and its anatomical and histological subtypes. We used data from a multi-case-control study (MCC-Spain) obtained from different regions of Spain. We included 2700 controls and 329 GC cases. Odds ratios (ORs) were calculated using mixed effects logistic regression considering quartiles of phenolic intake. Our results showed an inverse association between stilbene and lignan intake and GC risk (OR
= 0.47; 95% CI: 0.32-0.69 and OR
= 0.53; 95% CI: 0.36-0.77, respectively). We found no overall association between total phenolic acid and other polyphenol class intake and GC risk. However, hydroxybenzaldehydes (OR
= 0.41; 95% CI: 0.28-0.61), hydroxycoumarins (OR
= 0.49; 95% CI: 0.34-0.71), and tyrosols (OR
= 0.56; 95% CI: 0.39-0.80) were inversely associated with GC risk. No differences were found in the analysis by anatomical or histological subtypes. In conclusion, a diet high in stilbenes, lignans, hydroxybenzaldehydes, hydroxycoumarins, and tyrosols was associated with a lower GC risk. Further prospective studies are needed to confirm our results.
The aim was to assess the effect of adherence to the Mediterranean Diet, measured with five different indexes, on the risk of gastric cancer. Data come from the multicase-control study MCC—Spain, ...which included 354 gastric cancer cases and 3040 controls with data on diet. We used five indexes to evaluate adherence to the Mediterranean diet and assess the association between each pattern with the risk of gastric cancer, using multivariate logistic regression. The analyses were performed for the whole set of gastric cancer cases, by anatomical location (cardia and non-cardia) and by histological type (intestinal and diffuse). According to the used index, a high adherence protects one from gastric cancer (between 48% (aOR = 0.52; CI 95% = 0.28–0.94) and 75% (aOR = 0.25; CI 95% = 0.12–0.52)), from non-cardia (between 48% (aOR = 0.52; CI 95% = 0.36–0.75) and 65% (aOR = 0.35; CI 95% = 0.23–0.52)), and from the intestinal type (between 41% (aOR = 0.59; CI 95% = 0.36–0.95) and 72% (aOR = 0.28; CI 95% = 0.16–0.50)), but not from the diffuse type. In conclusion, high adherence to a Mediterranean diet pattern is a protective factor for the risk of gastric cancer, with greater adherence leading to greater protection.

Statement of Significance: To the authors' knowledge, this is the first scoping review to explore the literature regarding the environmental impacts of plant-based milks. This review aggregates all such known literature and identifies important knowledge gaps to prioritize for future research to fill. Such research would help identify the most sustainable choices for plant-based milks as well as potential instances where impacts would be comparable to or exceed those of dairy milks.
