Purpose: To determine the effects of dates vinegar on blood biochemical and hematological parameters in type 2 diabetic subjects. Methods: Current research focused on fifty-five subjects having blood sugar more than126 mg/dL. Participants ingested dates vinegar (20 mL) daily into their normal diets for a period of 10 weeks. Glycated hemoglobin (HbA1c), fasting blood sugar (FBS), total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), creatinine (Cr), urea, complete blood count (CBC), alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), potassium and folate levels were analyzed before, after 5 weeks and after the experiment Results: Dates vinegar improved the blood concentrations of HbA1c (6.80 ±2.34 to 6.17 ± 2.14 (%)),

In the current study, fresh‐cut broccoli was soaked in melatonin solution before cold storage (4°C, 95% RH) for 25 days. The results indicated that 100 µM melatonin treatment inhibited the increase of L* and b* values and retained higher hue angle, total chlorophyll content, and fresh weight during storage. Furthermore, 100 µM melatonin treatment obviously increased antioxidant contents including ascorbic acid, total phenols, and flavonoids, and enhanced the antioxidant activity of florets. Individual phenolic compounds including epicatechin, rutin, and quercetin were positively influenced by melatonin treatment. Superoxide dismutase (SOD), ascorbate peroxidase (APX), and catalase (CAT) activities were obviously enhanced by 100 µM melatonin treatment whereas peroxidase (POD) activity was significantly reduced. Moreover, florets treated with melatonin exhibited lower malondialdehyde (MDA), H2O2, and O2− levels. Our research concluded that melatonin treatment could be an effective technique for enhancing antioxidant capacity and improving the quality of fresh‐cut broccoli during cold storage. Practical applications Fresh‐cut fruits and vegetables are more prone to senescence than their intact forms during postharvest storage. Broccoli is a healthy vegetable and has high demands in many countries. In order to reduce economic losses, it is important to delay the senescence and maintain the quality of fresh‐cut broccoli during postharvest storage. In this article, 100 µM melatonin treatment was found to significantly enhance antioxidant capacity and delay the senescence of fresh‐cut broccoli florets, which maintained the quality of broccoli during cold storage. We believe that melatonin treatment can be applied for the preservation of more fresh‐cut fruits and vegetables.

While the use of vinegar to fi ght against infections and other crucial conditions dates back to Hippocrates, recent research has found that vinegar consumption has a positive effect on biomarkers for diabetes, cancer, and heart diseases. Different types of vinegar have been used in the world during different time periods. Vinegar is produced by a fermentation process. Foods with a high content of carbohydrates are a good source of vinegar. Review of the results of different studies performed on vinegar components reveals that the daily use of these components has a healthy impact on the physiological and chemical structure of the human body. During the era of Hippocrates, people used vinegar as a medicine to treat wounds, which means that vinegar is one of the ancient foods used as folk medicine. The purpose of the current review paper is to provide a detailed summary of the outcome of previous studies emphasizing the role of vinegar in treatment of different diseases both in acute and chronic conditions, its in vivo mechanism and the active role of different bacteria.
