Given the multitude of products and labels in extensive food databases, along with the dynamic nature of the food supply, food categorization and nutrient profiling are demanding, time-consuming, and costly processes.
Employing a pre-trained language model and supervised machine learning, this research automatically classified food categories and predicted nutritional quality scores, based on manually coded and validated data. The generated predictions were further analyzed by comparing them to models incorporating bag-of-words and structured nutritional data.
Data from both the University of Toronto Food Label Information and Price Database (2017, n = 17448) and the University of Toronto Food Label Information and Price Database (2020, n = 74445) were incorporated to analyze food products. Health Canada's Table of Reference Amounts (TRA), containing 24 categories and 172 subcategories, facilitated the classification of foods, while the Food Standards of Australia and New Zealand (FSANZ) nutrient profiling system assessed the nutritional quality of the items. Manual coding and validation of both TRA categories and FSANZ scores were undertaken by trained nutrition researchers. A pre-trained sentence-Bidirectional Encoder Representations from Transformers model, modified for this task, was employed to convert unstructured text from food labels into lower-dimensional vector representations. Subsequently, supervised machine learning algorithms, including elastic net, k-Nearest Neighbors, and XGBoost, were then utilized for multiclass classification and regression.
The multiclass classification algorithm, XGBoost, utilizing pretrained language model representations, reached 0.98 and 0.96 in predicting food TRA major and subcategories, demonstrating improved accuracy over bag-of-words methods. In predicting FSANZ scores, our proposed methodology achieved a comparable accuracy in predictions (R.

The incorporation of healthy, minimally processed plant-based foods into a balanced dietary pattern substantially influences the composition of the gut microbiome and supports improved cardiovascular and metabolic health. The relationship between diet and the gut microbiome in US Hispanics/Latinos, a group with a substantial prevalence of obesity and diabetes, is currently poorly understood.
Using a cross-sectional design, we analyzed the associations of three healthy dietary patterns—the alternate Mediterranean diet (aMED), the Healthy Eating Index (HEI)-2015, and the healthful plant-based diet index (hPDI)—with the gut microbiome in US Hispanic/Latino adults, and investigated the correlation between diet-related species and cardiometabolic characteristics.
Comprising a multi-site, community-based approach, the Hispanic Community Health Study/Study of Latinos is a cohort. Dietary assessments utilizing two 24-hour recalls were undertaken at the initial stage of the study (2008-2011). In 2014-2017, 2444 stool samples were sequenced using the shotgun method. To ascertain the correlations between dietary patterns and gut microbiome species and functions, ANCOM2 was employed, controlling for sociodemographic, behavioral, and clinical factors.
Dietary patterns reflecting better diet quality were associated with increased presence of species from the Clostridia class, including Eubacterium eligens, Butyrivibrio crossotus, and Lachnospiraceae bacterium TF01-11. Despite this shared characteristic, the specific functions contributing to better diet quality differed based on the dietary pattern, with aMED linked to pyruvateferredoxin oxidoreductase and hPDI connected to L-arabinose/lactose transport. The association between a less nutritious diet and a higher abundance of Acidaminococcus intestini was observed, and this correlation was further connected to functions in manganese/iron transport, adhesin protein transport, and nitrate reduction. Clostridia species, enriched by healthy dietary approaches, were demonstrably associated with favorable cardiometabolic characteristics, such as lower levels of triglycerides and a smaller waist-to-hip ratio.
Fiber-fermenting Clostridia species, a higher abundance of which is linked to healthy dietary patterns in this population, are consistent with previous studies in other racial/ethnic groups. A correlation exists between a higher diet quality and a decreased cardiometabolic disease risk, potentially influenced by the gut microbiota.
A higher abundance of fiber-fermenting Clostridia species in the gut microbiome of this population is a result of healthy dietary patterns, a correlation previously demonstrated in studies of other racial and ethnic groups. The gut microbiota's involvement in the salutary impact of a high-quality diet on cardiometabolic disease risk warrants exploration.
Variations in the methylenetetrahydrofolate reductase (MTHFR) gene, alongside folate intake, could modify how folate is handled in infants.
We analyzed the connection between an infant's MTHFR C677T genotype, dietary folate intake type, and the concentration of folate markers found in their blood samples.
The study compared 110 breastfed infants to 182 randomly assigned infants, receiving infant formula enriched with 78 grams of folic acid or 81 grams of (6S)-5-methyltetrahydrofolate (5-MTHF) per 100 grams of milk powder, lasting 12 weeks. BAPTA-AM Samples of blood were obtained at the ages of less than a month (baseline) and 16 weeks. The researchers analyzed the MTHFR genotype, and the quantities of folate markers and their catabolic products, including para-aminobenzoylglutamate (pABG).
At the study's commencement, individuals with the TT genotype (in comparison to those with alternative genotypes), Subjects CC had significantly lower mean (standard deviation) concentrations of red blood cell folate (all in nanomoles per liter) [1194 (507) versus 1440 (521), P = 0.0033] and plasma pABG [57 (49) versus 125 (81), P < 0.0001], but significantly higher plasma 5-MTHF [339 (168) versus 240 (126), P < 0.0001]. Regardless of genetic makeup, an infant formula containing 5-MTHF (in contrast to one without) is a common choice. BAPTA-AM A noteworthy rise in RBC folate levels was observed following folic acid supplementation, increasing from 947 (552) to 1278 (466), a statistically significant difference (P < 0.0001) [1278 (466) vs. 947 (552)]. Marked increases in plasma concentrations of 5-MTHF and pABG were seen in breastfed infants from their baseline levels to the 16-week mark, by 77 (205) and 64 (105), respectively. At 16 weeks, infants consuming infant formula, in accordance with current EU folate legislation, demonstrated significantly higher RBC folate and plasma pABG concentrations (P < 0.001) when compared to those fed a conventional formula. Across all feeding regimens, individuals with the TT genotype displayed 50% lower plasma pABG levels at 16 weeks than those with the CC genotype.
The folate content in infant formula, as prescribed by current EU regulations, produced a more pronounced increase in infant red blood cell folate and plasma pABG concentrations than breastfeeding, especially among infants with the TT genotype. Nevertheless, this intake did not entirely eliminate the disparities in pABG between genotypes. BAPTA-AM However, whether these differences hold any tangible clinical meaning remains elusive. This trial's data has been deposited and is available on clinicaltrials.gov. Further investigation of the trial NCT02437721.
Infants receiving folate from infant formula, as mandated by current EU regulations, exhibited a more pronounced elevation in red blood cell folate and plasma pABG concentrations compared to breastfed infants, particularly those possessing the TT genotype. However, the ingestion did not completely quell the variations in pABG attributable to differing genotypes. The question of whether these differences carry any clinical weight, however, remains unresolved. This trial is listed in the clinicaltrials.gov database. This clinical trial is identified by the code NCT02437721.
Studies on the correlation between vegetarian diets and breast cancer incidence have exhibited inconsistent outcomes. A scarcity of studies have probed the link between a gradual decrease in animal food intake and the quality of plant foods in their association with BC.
Explore the connection between plant-based dietary choices and breast cancer risk specifically within the postmenopausal female population.
A comprehensive study of the E3N (Etude Epidemiologique aupres de femmes de la Mutuelle Generale de l'Education Nationale) cohort, which included 65,574 participants, was conducted over the timeframe of 1993 to 2014. Subtypes were identified in incident BC cases after a review of the corresponding pathological reports. To develop cumulative average scores for healthful (hPDI) and unhealthful (uPDI) plant-based dietary patterns, self-reported dietary intakes were analyzed at both baseline (1993) and follow-up (2005), and the results divided into five groups (quintiles).
