Introduction: Prevalence of overweight and obesity, a condition that promotes development of chronic degenerative diseases, has increased in Mexico in recent years. Implementation of strategies to increase daily consumption of vegetables, legumes, whole grain cereals, and fruits by the population will result in an adequate intake of soluble fiber, antioxidants, protein of vegetable origin, and vitamins., Objective: To assess the effect of a commercial food product prepared using 6 legumes on some anthropometric and biochemical parameters in apparently healthy subjects., Methods: A randomized dietary intervention trial where subjects in the study group received for three months 15g of the product, administered daily in periods of five days with two days of rest. Before and after intervention, anthropometric and dietary assessments were performed, and serum glucose, lipid profile, insulin, ultrasensitive C-reactive protein, malondialdehyde (MDA) and insulin resistance (HOMA index) were measured. A Mann-Whitney U test was used and values of P<0.05 were considered statistically significant., Results: Sixty university students were included in the study (53% males). At the end of the intervention, decreases were seen in serum glucose levels (P=0.001), MDA (P=0.001) and HOMA index (P=0.017), but there were no significant changes in all other parameters., Conclusions: Daily intake of 15g of the legume-based food product improved serum glucose and malondialdehyde levels in the study group, as well as insulin resistance; which could be attributed to the presence of polyphenols and isoflavones such as genistein in legumes., (Copyright © 2019 SEEN y SED.

Background: Decrease in the capacity to deglution solids and liquids is a problem in many people, this problem decreases quality of life. The main objective of our work was to evaluate the influence in elderly ambulatory patients with dysphagia of a texture modified diet ready to use on nutritional parameters and quality of life., Methods: We enrolled 29 patients from Nutrition Department with dysphagia and an age over 70 years. Patients received a texture modified diet supplemented with dehydrated nutritional products (Resource Ready) (1,633 kcal, 59,9 g proteins (16%), 52,1 g lipids (29%), 231,7 g carbohydrates (57%), 11,1g de fiber, 82 mg cholesterol). Before and after 3 months of starting the treatment, we recorded a blood analysis, nutritional anthropometric evaluation (tricipital skinfold, midarm circumference, midarm muscle circumference, weight, height and body mass index), a bipolar bioimpedance and a dietary questionnaire of 3 days. SF36 as a questionnaire of quality of life was used before and after nutritional treatment., Results: A total of 29 patients were recruited with a sex distribution of (18 females and 11 males), and an average age of 79,5+8,59 years. A 25,7% of patients had head and neck tumors, a 24% dementia and a 41,3% chronic neurological deterioration. After treatment, we detected an improvement in weight, fat mass, fat free mass, total proteins, albumin, transferrin and lymphocytes. Caloric, protein fat and carbohydrate intakes increased in a significative way. Caloric intake corrected by weight improved (26.1 +/- 5.7 cal/kg vs 28.9 +/- 4.5 cal/kg: p < 0.05). Quality of life improved significantly (SF 36 score 94.7 +/- 15 points vs 99.3 +/- 10 points; p < 0.05)., Conclusion: A texture modified diet with dehydrated nutritional products improved dietary intake, nutritional status and quality of life of ambulatory elderly patients with dysphagia.

Production of new protein-based products for special nutrition such as hypoallergenic infant formulas, fortified beverages and nutraceutics, require ideal ingredients. Protein ingredients were developed by enzymatic hydrolysis and methionine synthesis of soy protein. Hydrolysis was done at 4% (w/v) using porcine pancreatic enzymes (4% w/w), 50 degrees C, 6 h and pH 8. After drying powder was resuspended (20% w/v) and incubated with 7.6% (w/w) methionine methyl-ester, 1% (w/w) chymotrypsin and 3 M glycerol, 37 degrees C, 3 h and pH 7. Hydrolysates were fractionated by ultrafiltration (UF) before and after enrichment (E): FI > 10, 10 > FII > 3 and 3 > FIII > 1 kDa. Functional properties, amino acid content, anti-physiological factor activities and antigenicity were assayed for all the UF fractions and the soybean meal. Protein quality bioassay and sensorial test of an non-enriched fraction and an enriched fraction were performed. Functional properties were positively modified by hydrolysis and synthesis by using a minimum time and methionine added for the last reaction. After UF all the fractions under 10 kDa showed 100% solubility (pH 4 and 7), good clarity, acceptable foam capacity and negligible antigenicity and antiphysiological activities. Additionally, methionine enrichment enhanced their nutritional value, upgrading sulfur amino acid requirements for infants and adults. Because functionality and nutritional value FIII-E could be used for hypoallergenic infant formulas, FII-E for fortified soluble formulas and nutraceutics and FI-E for a semi-solid baby food.
