Objectives: To evaluate the association between the consumption of different dietary fats with the quality of the diet, insulin resistance, and hyperhomocysteinemia in adults.

Methods: Cross-sectional study conducted with 624 overweight subjects (73.7% females). Assessments of food intake (24h food recall and health eating index-HEI), anthropometry, and biochemical assays of fasting glucose, insulin (HOMA-IR and ß calculus) and homocysteinemia were performed.

Results: The low quality of diet was associated with the vegetable oil at 3rd quintile (≥1.5-2.0 servings) showed risk 2.9 times and cholesterol at quintiles 2nd, 3rd, and 4th was 2.0 times. HOMA-IR was higher at 5th quintile of saturated fat (≥10,7% - total caloric value) with risk of 60% and hyperhomocysteinemia the vegetable oil at 3rd quintile (>1.5-2.0 servings) with risk of 12.0 times and 5th (≥3.5 servings) 7.1 times. However, significance disappeared when adjusted for anthropometric variables.

Conclusion: Dietary fats were associated with the harm diet quality, insulin resistance, andhyperhomocysteinemia. However, associations are dependant of demographic variables, dietetic, and nutritional state.

Several clinical studies have evaluated the relationship between copper on colorectal cancer (CRC), but the results are contradictory. This study aimed to conduct a systematic review and meta-analysis to investigate copper measured in two biological matrices (serum/plasma/blood and tissue) and dietary intake in CRC patients compared to healthy controls. We conducted a comprehensive and systematic search in PubMed, Scopus, Embase and Web of Science.

UNCPBA, Facultad de Ingeniería, Departamento de Ingeniería Química y Tecnología de los Alimentos, TECSE, Olavarría, Buenos Aires, Argentina.

The growing consumer demand for healthier foods that help reduce the risk of chronic diseases has driven the food industry to innovate with nutritionally and technologically viable products. This trend and the nutritional gaps in gluten-free diets have spurred the exploration of unconventional, high-quality ingredients like flour from pseudocereals, legumes, and oilseeds. This study evaluated the nutritional and functional profiles of chia expeller and flours from buckwheat, green/yellow peas, and rice to study their potential as techno-functional ingredients for new gluten-free premixes.
