Antioxidant Enriched Nutri Bar Supplementation on the Serum Anti Oxidant Status and Performance of Track and Field Athletes

Background: Adequate nutrition knowledge among athletes becomes vital. Knowledge, Attitude and Practices (KAP) regarding food intake of athletes become essential more so to have antioxidant rich diets. Antioxidants supplementation may provide protection against negative health consequences of oxygen free radicals caused by aerobic and re-sustained exercise.

Aim: Is to find out the efficacy of anti- oxidant rich nutri bar supplementation on the anti-oxidant status and physical fitness components of the athlete’s.

Methods: Single blind study was employed. Study group (n=20) subjects were supplemented with the formulated nutri bars daily for a period of 3 months and control group with a placebo. Bio-chemical parameters GSH, GSH-px, SOD, Vitamin C, lipid profile, serum LPO and physical fitness tests were assessed at baseline and after 90 days. Statistical analysis was performed using SPSS (version 15).

Results: The mean age was 18 ± 3.2 yrs. 60% of the selected athletes were males and 40% females. The main source of nutrition information was from coaches (56%) and magazines (30%). Supplemented group athletes showed a significant increase in serum levels of SOD (p=0.000), LPO (p=0.005), GSH (p=0.000) than control group. Significant decrease was observed in total cholesterol (p=0.000) and LDL Cholesterol (p=0.000) than placebo. Vitamin C levels and GSH-px, HDL decreased in supplemental group but there was a significant decrease in control group (p=0.000, p=0.02, p=0.000). Significant improvement in all six physical fitness tests was observed in supplemented group (p=0.000), whereas in control group pushups test, vertical jump and agility tests alone did not find statistical significance.

Conclusion: False beliefs, food fads, have brought in major drawback in performance; hence appropriate nutrition knowledge is necessary for winning. Antioxidant effects of the formulated food were useful in improving the endurance of athletes.

Gut Microbiota: A Potential Biomarker to Define Individual

It has scientifically been proven that we are not born alone, as we get colonized by innumerable number of bacteria at the time of birth and by adulthood we have trillions of bacteria colonizing every surface of the body

Nutritional Evaluation of Lunches Consumed In Community Restaurants in Brazil

This work aims to evaluate the nutritional adequacy of meals consumed by those who have lunch at Community Restaurants (CRs) in Brazil. This is an exploratory cross-sectional study that evaluated 1771 adult and elderly individuals distributed in 36 CRs in all geographic regions of Brazil. The study evaluated the nutritional status of participants and the lunch food intake during three consecutive days, by direct observation and weighing the meals. The usual consumption was estimated, and descriptive analyzes, correlations, non parametric tests, and the Tukey test by ANOVA were performed. It was observed that 36.9% of the population is overweight and 16.9% is obese. Lunch energy intake was 880 calories, with adequate consumption of fiber and iron. The energetic consumption of saturated fat was adequate, but the consumption of essential fatty acids was below the recommended level. Sodium intake showed high inadequacy (41%). A high prevalence of overweight/ obesity in this population was observed. Lunch consumed in the CRs provides adequate amounts of energy, fiber and iron, but it is necessary to adequate the sodium and the quality of fats.

Dyslipidemia and Associated Risk Factors among Health Sciences University Students

The Saudi community has experienced considerable transformations in lifestyle and eating habits during the past 30 years. This study aimed to determine dyslipidemia prevalence and related risk factors among female Health Sciences students in Taif University, Kingdom of Saudi Arabia (KSA).A total random sample of 148 female university students from Health Sciences colleges aged 18.5-22.1 years, was selected to contribute to the present study. Subjects were screened for serum lipid chemistry, obesity/overweight and associated risk variables via completion of pre-examined food frequency questionnaire. Anthropometric measurements, namely height, weight, and waist circumference (W_C) were determined. Fasting blood samples from each participant was taken for determination of blood lipid parameters. Obtained data was analyzed using the Statistical Package for Social Sciences (SPSS) program. The overall dyslipidemia rate was 58.90%. The prevalence of hypertriglyceridemia, hypercholesterolemia, high levels of low density lipoprotein (LDL-c), low levels of high density lipoprotein (HDL-c), and high risk ratio of total cholesterol (TC)/HDL-c were 2.1%, 9.5%, 8.8%, 54.7%, and 33.8%, respectively. Low HDL-c level was the major prevalent dyslipidemia among female university students. Overweight/obese students were more likely to demonstrate at least one unfavorable blood lipid concentration. BMI was substantially correlated to high level of LDL-c and high risk ratio of TC/HDL-c. Living and eating with a family and TV viewing were considerably associated with unacceptable amounts of HDL-c. Daylight sleep had significant impacts on hypercholesterolemia, and undesirable level of LDL-c, while only liver uptake had significant effect on hypercholesterolemia and high level of LDL-c. This study strongly recommends creation of health education program to provide university students with information regarding healthy lifestyle and eating habits that improve good blood lipid profile.

Topical Application of Hesperidin, a Citrus Bioflavanone Accelerates Healing of Full Thickness Dermal Excision Wounds in Mice Exposed to 6 Gy of Whole Body Radiation

Abstract The irradiation leads to delayed wound healing and the paradigms that can enhance the healing of irradiated wound will be useful, especially in conditions were wounds are exposed to ionizing radiation before or after surgery. The wound healing activity of various concentrations of hesperidin ointment was investigated in mice exposed to 6 Gy of whole body γ-radiation after infliction with a full thickness circular excision wound of 15 mm diameter by measuring wound contraction using videography and determining the mean wound healing time. Topical application of different concentrations of hesperidin ointment twice daily accelerated the healing of irradiated wounds in a concentration dependent fashion when compared to placebo application on the irradiated wounds. A maximum wound contraction was observed for 5% hesperidin ointment when compared to the other concentrations. Likewise, the mean wound healing time also reduced in a concentration dependent manner in the animals receiving a topical application of 5% hesperidin, where it was shorter by 2.7 days when compared to the irradiated placebo controls. The present study demonstrates that topical application of hesperidin accelerates healing of normal as well as irradiated wounds and may serve as a useful paradigm for the management of irradiated wounds in a clinical setting and after nuclear disaster. The acute toxicity determination of hesperidin showed that animals were able to tolerate 5 g/kg body weight and it was no observed adverse effect level (NOAEL) dose. No symptoms of toxicity in any form were observed at this dose. In vitro free radical scavenging revealed that hesperidin scavenged, DPPH, hydroxyl, superoxide, ABTS+ and Nitric oxide radical in a concentration dependent manner.

Tracing the In Vitro Antioxidant Activity of Some Rare Honeys Produced in the Hellenic Zone

Background: Honey is a complex mixture of numerous phytochemicals that possess considerable antioxidant activity. Aim: The aim of this study was to investigate the in vitro antioxidant activity of some rare honey types produced in the Hellenic zone.

Methods: Fourteen honey samples were collected during two consecutive harvesting years from 5 different regions in Hellas. Honeys belonged to arbutus, asfaka, chestnut, citrus, oak, pine, sage, and thyme. The in vitro antioxidant activity was estimated using the 2, 2-diphenyl-1-picryl-hydrazyl spectrometric assay.

Results: The in vitro antioxidant activity was greatly affected by honey botanical origin. The higher in vitro antioxidant activity (%AA) and effective concentration (EC50 ) was recorded for chestnut honey followed by those of oak, pine, and arbutus honeys.

Conclusion: Apart from its use as a natural sweetener, honey, especially in the form of an aqueous solution, may be used in the daily diet as a good source of water soluble antioxidants
