Beetroot is a widely consumed crop all over the world and contains plenty of bioactive compounds. In this study, we analyzed the bioactive as well as the antimicrobial properties of the oven-dried beetroot (pulp and peel) using different solvents. The 50% methanolic extract yielded the highest content of total polyphenols and total flavonoids as well as the reducing power of the beetroot. The beetroot peel exhibited a higher content of total polyphenols, total flavonoids, and reducing power activity under all the extraction solvents. Mixture of methanol and water (50% v/v) extracted the highest chlorogenic acid (78.24 mg/100 g) of the dried beetroot peel, while 1,2-dihydroxybenzene was the most noteworthy phenolic compound (42.52 mg/100 g) in beetroot peel methanolic extract. The 50% methanolic extract of both peel and pulp demonstrated the highest antibacterial and anticandidal potential. These results can be helpful for beetroot consumption.

The eggplant is an important vegetable that is used all over the world and it contains valuable bioactive properties. Cooking methods affect the nutritional value as well as the functional characteristics of vegetables. This study investigated the effect of air-frying at different temperatures and the extraction solvents on the bioactive properties of eggplant. The eggplant air-fried for 25 min and extracted with 50% ethanol exhibited the highest total flavonoid content (35.10 mg catechin equivalent per gram dry weight), while its total polyphenol content was found as 87.81 mg gallic acid equivalent per gram dry weight. The uncooked sample exhibited the lowest DPPH scavenging (IC50: 422.12 mg/mL reducing power: 0.914), while the highest DPPH scavenging activity (IC50: 2.87 mg/mL; reducing power: 0.936) was recorded for the sample air-fried for 25 min and extracted with 50% ethanol. The highest amount of tannic acid was found in medium-cooked eggplant, while chlorogenic acid was the highest in the high-cooked sample. These results might be helpful for functional food processors.

Fruits and vegetables constitute a considerable amount of antioxidants and among them eggplant is a rich source of polyphenol compounds. This study investigated the bioactive and antimicrobial properties of eggplant under different degree of microwave cooking. The eggplant was cooked for 7 min (light cooked), 10 min (medium cooked), and 15 min (high cooked). The highest total polyphenol content was observed in the light cooked eggplant sample (27.35 mg gallic acid equivalent (GAE)/g dry weight (DW)) followed by high cooked sample (26.10 mg GAE/g DW), while the lowest total polyphenol content (2.79 mg GAE/g DW) was obtained for the uncooked (control) sample. The total polyphenol content of the samples ranged in the following order; light cooked > high cooked > medium cooked > uncooked. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging of eggplant ranged between 16.16% (control) and 47.88% (high cooked). The highest reducing power was exhibited by the light cooked (absorbance 1.708) eggplant sample followed by the high cooked (absorbance 1.597), while the lowest reducing power was shown by uncooked sample (absorbance 0.389). Moreover, antimicrobial studies showed that light cooked eggplant sample demonstrated broad-spectrum inhibition of growth in Gram-positive as well as Gram-negative bacteria and Candida albicans. Slightly lower antimicrobial potential was exhibited by medium cooked eggplant sample while no antibacterial or antifungal activity was recorded for the extract of high cooked eggplant sample. Microwave cooking might be a method to enhance the antioxidant and antimicrobial potential of eggplant.

BackgroundThe obesity epidemic is a pressing global health concern, as obesity rates continue to climb worldwide. The current study was aimed mainly to evaluate the correlation between thyroid hormones and homeostatic model assessment of insulin resistance in Saudi obese women with metabolic syndrome.Methods100 obese women aged 25 to 55 years were clinically evaluated, from which 72 women were diagnosed with the metabolic syndrome and 28 without metabolic syndrome. Insulin resistance was quantified using the homeostatic model assessment of insulin resistance method and the resulting values were analyzed for association with demographic, clinical, and metabolic parameters.ResultsThis analysis revealed that body mass index, systolic blood pressure, and biochemical parameters and fasting insulin showed statistically higher levels in the group with metabolic syndrome compared to the group without metabolic syndrome. Similarly, values of waist circumference, fat ratio, cholesterol, free thyroxine, free triiodothyronine and homeostatic model assessment of insulin resistance results were higher in the group with metabolic syndrome as compared to the group without metabolic syndrome. Correlation analysis revealed positive association of thyroid-stimulating hormone with waist circumference (P=0.01), total cholesterol (P=0.002), fasting insulin (P=0.03) and homeostatic model assessment of insulin resistance results (PHomeostatic model assessment of insulin resistance test revealed elevated level with positive association of body mass index, waist circumference, biochemical parameters and thyroid-stimulating hormone in insulin resistant obese women. Higher level of free triiodothyronine was found to be associated with low insulin sensitivity.

Alzheimer’s disease (AD) is a progressive neurodegenerative disease, and due to various physiological and psychological factors the patients are at risk of nutritional insufficiencies. The purpose of this study was to assess the dietary fatty acid intake and its effect on plasma fatty acids in elderly Saudi women and to compare the differences in their food and plasma fatty acid profile on the basis of their residence. A total of 76 elderly women (50–100 years) were recruited through a random sampling method. A structured proforma was designed to gather information related to their age, income, dietary habits, and presence of any disease and awareness of AD. A 24-h dietary recall method for 3 days and food frequency questionnaire, concentrating on fish consumption and consumption of foods rich in ω-3 fatty acids, which was planned by dietitians, was used for dietary assessment. The gathered data were then analyzed using food processor software. The blood samples were collected to determine plasma fatty acids. The mean age of women diagnosed with AD was more than 75 years, and the prevalence of illiteracy was higher among AD subjects. As compared to the AD group, the concentration of LA and total ω-6 was significantly (p ≤ 0.05) higher in the control group from both recruitment sites [National Guard Health Affairs, King Abdulaziz Medical City, Riyadh (NGH) and Social Welfare Homes for the Elderly (SWH)]. Similarly, the concentrations of EPA, DHA, and ω-3 were also slightly higher in the control group at both sites, but the difference between the control and AD subjects was only significant (p ≤ 0.05) in subjects from NGH. We found no significant difference in the ω-6/ ω-3 ratio between groups. Also, no significant difference was found in the mean level of the plasma fatty acid when comparing the control and AD groups. The concentration of DHA in controls only and AA, EPA and ω-6 in both control and AD were significant (although weakly) correlated with their respective dietary intakes. No correlations were found between the intake of 18 C precursors (LA and ALA) and plasma levels of their long chain derivatives (AA, EPA, and DHA). Education, income, overall health status and the concentration of various fatty acids from food was higher and better in subjects from SWH than NGH. The lower plasma level indicates lower impaired systemic availability of several nutrients. We found that dietary intervention might play a role in the prevention of AD.

The purpose of this study was to investigate the effect of long-term supplementation with dietary lipids on growth and fatty acid composition of rabbit’s brain. Soybean oil, fish oil, sesame oil, docosahexaenoic acid and arachidonic acid were fed to weanling rabbits for 100 days. The rabbits were decapitated and brain sample was removed, homogenized and fatty acid concentration was measured by gas chromatography. Dietary lipids had a distinct effect on growth rate only in males. Rabbits fed the fish oil diet showed the highest total w-3 fatty acids and lowest w-6/w-3 ratios. Rabbits fed the DHA diet had highest total saturated fatty acids and lowest values of total MUFA, total PUFA, total w-6, and total w-3 in females. This study shows that w-6/w-3 ratios have tremendous effect on the fatty acid composition of rabbit’s brain. Effect of treatment was not significant among different gender except for total saturated, ARA, C20:1 and C16:0. FO, DHA and DHA+ARA groups showed the w-6/w-3 ratios within the recommended range. This study shows that fatty acid composition of brain can be modulated by dietary lipids and long-term supplementation of dietary lipids especially fish oil (FO) has very good effect on the fatty acid composition of rabbit’s brain.

Fats and lipids are common components of food and may perform essential roles. Their types may be more important with regard to health and disease than their amount. The objective of this review is to summarize the information on the role of functional lipids on human health. New research has linked functional lipids to the prevention and treatment of many diseases. Functional lipids such as omega-3 and omega-6 fatty acids, conjugated linoleic acids, medium chain triglycerides, and phytosterols have many beneficial effects on human health such as in obesity, bone health, and in treating and managing depression, blood pressure, cardiovascular health, etc. The ratio of omega-3 and omega-6 polyunsaturated fatty acids regulates the production of eicosanoids, which are the metabolites of these series of fatty acids. Scientific evidence has shown encouraging improvements in patients and beneficial effects in healthy persons with the use of supplemental and dietary forms of functional lipids.
