Fermentation has shown to be an effective technique in bioactive peptides release. That is why in this study antihypertensive, antithrombotic, and antioxidant activity was evaluated during amaranth proteins fermentation with Lactobacillus casei Shirota and Streptococcus thermophilus 54102 in mono and combined culture. During fermentation an increase of free amine groups was observed, and no statistical differences among monocultures were shown, getting higher concentration in combined culture. This was related to antihypertensive and antioxidant activities, where the highest values were also found in the combined process (45% of angiotensin-converting enzyme inhibition, and 168 μmol Trolox equivalents per liter [TE/L] for 2,2-diphenyl-1-picrylhydrazyl, 268 μmol TE/L for 2,2′-azino-bis 3-ethylbenzothiazoline-6-sulfonic acid, and 381 μmol Fe2E/L for ferric reducing ability of plasma). On the contrary, antithrombotic activity was not related to free amine groups during fermentation, having the highest bioactivity in different moments in each experiment. L. casei Shirota and S. thermophilus 54102 are strains that are able to release bioactive peptides from amaranth protein, although amaranth is not a common matrix for the development of lactic acid bacteria. In addition, in this study it was observed for the first time that lactic acid strains are able to release bioactive peptides from amaranth protein. In addition, this methodology could be part for the development of fermented beverages, different from fermented milk, to diversify matrix to obtain a novel functional food.

Correct nutrition is important for keeping good health; to attain that, the diet has to include vegetables such as quelites. The objective of this study was to determine the glycemic index (GI) and glycemic load (GL) of rice and a tamal prepared with and without two species of quelites: “alache” (Anoda cristata) and “chaya” (Cnidoscolus aconitifolius). The GI was measured in 10 healthy subjects, 7 women and 3 men, with the following mean metrics: age, 23 years old; body weight, 61.3 kg; height, 1.65 m; body mass index, 22.7 kg/m2; and basal glycemia, 77.4 mg/dL. Capillary blood samples were collected within 2 h after the meal. White rice (rice with no quelites) had a GI of 75.35 ± 15.6 and a GL of 36.17 ± 7.8; rice with alache had a GI of 33.74 ± 5.85 and a GL 33.74 ± 1.85. White tamal had a GI of 57.33 ± 10.23 and a GC of 26.65 ± 5.12; tamal with chaya had a GI of 46.73 ± 22.1 and a GL of 23.36 ± 11. The GI and GL values recorded for the combination of quelites with rice and tamal confirmed that quelites could be a good alternative for healthy diets.

Metabolic Syndrome (MS) is recognized as a cluster of cardiovascular risk factors. All components of MS have a genetic base. Genes of the renin angiotensin system are potential candidate genes for MS. We investigated whether angiotensin converting en-zyme (ACE) gene polymorphism increases suscep-tibility to MS as an entity in a Mexican population. In a cross-sectional study, 514 individuals were studied including 245 patients with MS and 269 subjects without MS criteria. ACE gene polymorphism was detected using PCR. MS was defined according to The National Cholesterol Education Program Expert Blood Cholesterol in Adults (Adult Treatment Panel III) criteria, except that the raised fasting plasma glucose ≥100 mg/dl criterion for identification of intolerance fasting glucose was modified in accordance with the suggestion of the American Diabetes Association. Patients with MS were sig - nificantly different from subjects without MS in relation to mean body mass index (BMI), waist circumference (WC), systolic blood pressure, diastolic blood pressure, glucose, total cholesterol (C), triglycerides, HDL-C, and LDL-C (P<0.0001). The differences in the mean BMI, WC, glucose, total cholesterol, triglycerides, LDL-C, and HDL-C were maintained in patients with the MS and DD genotypes (P<0.01). The DD genotype was strongly asso - ciated with MS (adjusted OR = 5.48, 95% CI 3.20-9.38, P<0.0001). We concluded that the DD genotype increases susceptibility to MS in a Mexican pop - ulation. These results indicate that pharmacological and non-pharmacological treatment and a reduction in body fat will have important therapeutic im - plications in this disease.
