Introduction: Imbalance between total energy intake and expenditure causes accumulation of excess fat and sugar in the body which leads to development of diabetes mellitus type II, obesity, and metabolic syndrome. These harmful diseases accelerate aging and cause fatal metabolic disorders as people age. Inhibition of pancreatic lipase, and alpha glucosidase digestive enzymes is a step that can reduce excess fat and sugar from the body, which is an essential component of healthy aging. Methodology: In this study, aqueous and 50% ethanolic extracts of Hibiscus sabdariffa were investigated for their inhibitory activities on pancreatic lipase and alpha-glucosidase, in addition to their antioxidant activities (using UV-vis spectrophotometer). Results: Both extracts displayed antioxidant properties, indicated by IC50 of 5166.80 mg/mL for H. sabdariffa aqueous extract and 2809.10 mg/mL for H. sabdariffa 50% ethanolic extract. The extracts also suppressed the activities of pancreatic lipase and alpha-glucosidase enzymes, which suggests possible antiobesity and anti-diabetic activities. H. sabdariffa aqueous extract inhibited pancreatic lipase activity with IC50 of 167.5+/-12.7 mg/mL, whereas H. sabdariffa 50% ethanolic extract inhibited the enzyme with an IC50 of 790.65+/-16.02 mg/mL. Both H. sabdariffa aqueous and ethanolic extracts also successfully inhibited alpha-glucosidase enzyme activity with IC50 949.88 +/-10.83 mg/mL, and 378.33 +/-4.20 mg/mL, respectively. Conclusion: Taken together, the outcome of the investigations offers the possibility of the extracts as an anti-obesity, anti-diabetic, anti-metabolic and anti-aging agent, which can be developed into supplements for adults to prevent the occurrence of these prevalent diseases and delay the onset and effects of aging.

Abstract The aim of this study was to investigate the effects of wheat shorts, a milling by-product, on some properties of pasta. For this purpose, wheat semolina was replaced with wheat shorts at 15, 30, and 45% levels in pasta formulation. Some physical, chemical, and sensory properties of pasta samples were evaluated and compared with control samples prepared with durum wheat semolina. As the concentrations of shorts increased in the pasta formulation, the brightness values decreased and the redness values increased. The ash, fat, total dietary fibre, total phenolic content, antioxidant activity, and mineral content increased with the use of shorts. The highest solid loss value (10.28%) was found in pasta samples containing 45% shorts. The addition of shorts up to 30% presented similar overall acceptability scores to control pasta samples. As a result, it was observed that as the shorts content of the samples increase, the nutritional value and the levels of some components that affect health positively, increase as well. So, the samples containing 30% shorts appear to be at forefront due to health effects and overall acceptability scores.

Rosehips, which are commonly grown in nature in shrub form, are always popular due to their importance in terms of nutrition and health. Because fruits are rich in vitamin C, total phenol and mineral contents and antioxidant activities. Nowadays, there is high demand for natural products. Rosehip grows spontaneously in Turkey. In this study, 9 individuals were examined. Consequently, significant differences were stated according to genotypes for pomological and phytochemical characteristics. Vitamin C, phenol and antioxidant activity were found to affect P and Zn nutrients. Additionally, it was detected that P, K, Ca, Mg, Na Fe, Cu, Zn and Mn contents ranged in 0.09-0.17%, 1.35-1.86%, 1.05-1.44%, 0.43-069%, 50.00-100.00 ppm 28.50-48.30 ppm, 3.30-7.00 ppm, 8.06-12.56 ppm and 50.85-85.35 ppm, respectively. In this context, one of the genotypes has been found promising due to its content.
