Omega-3 Index improves after increased intake of foods with omega-3 polyunsaturated fatty acids among US service academy cadets.

The inclusion of omega-3 fatty acids in our dietary intake is important for performance and recovery and may reduce the risk of various health issues. Studies have shown the omega-3 fatty acid status of US service members is low. The purpose of this study was to evaluate whether offering fish and omega-3-enhanced foods would increase the Omega-3 Index (O3I). We hypothesize cadets will increase O3I with enhanced omega-3 options more than fish alone. Food service venues at 3 US service academies offered fish and other omega-3 foods to cadets for 12 weeks. Questionnaires were used to collect information on the dietary habits and omega-3 food intake of participants. The O3I of each participant was measured at baseline, mid- (6 weeks), and after data collection (12 weeks) time points. Following the 12 weeks, we found a significant increase in O3I. More specifically, the intake of other omega-3 foods, smoothies (3 per week) and toppings (3 per week), increased O3I in cadets. This study identified a strategy encouraging omega-3 food intake and improving O3I among cadets. These results help us understand how we can more effectively impact military service member nutrition for optimal health and performance.

Omega-3 Fatty Acids: Benefits for Performance and Recovery.

Full-spectrum human performance optimization (HPO) is essential for Special Operations Forces (SOF). Nutrition is one part of HPO and is important for all aspects of performance. One area of increased interest in this regard is omega-3 polyunsaturated fatty acids (omega-3). Research has indicated that Servicemembers (SM), including SOF, do not eat the recommended 2 to 3 servings per week of fatty fish and have low omega-3 levels. Therefore, alternative approaches are warranted. The purpose of this article is to highlight the potential mental and physical health and performance benefits of omega-3. Consuming omega-3 on a regular basis would not only be beneficial for the health of SOF but also for their training and overall performance.

Optimization of Omega-3 Index Levels in Athletes at the US Naval Academy: Personalized Omega-3 Fatty Acid Dosage and Molecular Genetic Approaches.

The Dietary Guidelines for Americans recommend increasing the intake of omega-3 polyunsaturated fatty acids. The Omega-3 Index (O3I) is one marker used to assess omega-3 status. The O3I national average is 4.3%, which translates into a high risk for developing cardiovascular disease. Research has reported an association between variants in the two desaturase encoding genes, fatty acid desaturase 1 and fatty acid desaturase 2 (FADS1/2), and the concentration of O3I. The aim of this study was to assess whether a personalized dosage of omega-3 supplementation would lead to an O3I ≥ 8%. A secondary aim was to identify if changes in O3I levels would be associated with either of the two FADS1/2 variants. METHODS: This interventional study had a pre- and post-intervention design to assess changes in O3I. Ninety participants completed demographic, biometrics, O3I, and genetic testing. Participants were provided a personalized dose of omega-3 supplements based on their baseline O3I. RESULTS: The majority (63%) of participants were 20 year old white males with an average O3I at baseline of 4.6%; the post-supplementation average O3I was 5.6%. The most frequent genetic variants expressed in the full sample for FADS1/2 were GG (50%) and CA/AA (57%). CONCLUSIONS: O3I was significantly increased following omega-3 supplementation. However, it was not possible to conclude whether the two FADS1/2 variants led to differential increases in OI3 or if a personalized dosage of omega-3 supplementation led to an O3I ≥ 8%, due to our study limitations.

The effect of peer influence on the amount of physical activity performed in 8- to 12-year-old boys.

The purpose of this study was to determine the amount of physical and sedentary activity normal-weight and at-risk-for/overweight boys perform when alone, with a peer of similar weight and with a peer of different weight. Participants included boys, ages 8-12 years, classified as either normal-weight (<85th BMI percentile; N = 12) or at-risk-for/overweight (<85th BMI percentile; N = 12). At-risk-for/ overweight boys allocated a greater amount of time to sedentary activities and accumulated fewer accelerometer counts than normal-weight boys in the alone condition. Once paired with a peer of either similar or different weight there were no differences between groups. These results indicate the presence of an unknown peer has a positive effect on at-risk-for/overweight children's physical activity behavior.

Dietary Supplements: Knowledge and Adverse Event Reporting Practices of Department of Defense Health Care Providers.

INTRODUCTION: The purpose of the study was to assess the knowledge of dietary supplements (DS) and adverse event (AE) reporting practices of the Department of Defense health care providers. AEs related to use of DS are not uncommon. However, it is estimated that less than 2% of AEs are reported. This is problematic given the Food and Drug Administration relies on AE reports to identify and ultimately remove unsafe products from the market. Inadequate reporting of AE puts all DS users at risk. MATERIALS AND METHODS: Cross-sectional design was used. Electronic surveys were sent to the Department of Defense health care professionals (HCPs) and Emergency Medicine (EM) physicians asking questions about practices regarding DS and AE knowledge and reporting behaviors. The surveys were open for 5 months. During this period of time, HCPs received three email reminders following the initial email to enhance participation. The computer package IBM SPSS version 25 software (IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 21.0, Armonk, New York) was used for statistical analysis. Frequency distributions of the responses were analyzed. RESULTS: Of the 1,700 surveyed, 270 HCPs and 68 EM physicians completed the surveys. At least 39% of HCPs reported never receiving formal DS training. Seventy-two percent of HCPs reported asking their patients about the use of DS. However, when asked if they knew where to report an AE, only 40% of HCPs knew where to report an AE and only 38% knew how to report an AE. Of the EM physicians, only 38% asked their patients about DS. However, a majority (78%) reported that they had encountered an AE. EM physicians also reported they lacked knowledge regarding where (87%) and how (87%) to report AE. CONCLUSIONS: It is clear that physician and nonphysician HCPs would benefit from additional training about DS and how and where to report suspected AE. Providing regular training on risks, common AE, and how and where to report an AE would help fill the knowledge gap in the ever-changing DS industry. Addressing these issues and coming up with a solution to integrating AE reporting into clinical care could improve health care practices and increase AE reporting to the Food and Drug Administration, which would have a beneficial impact on patient care, public safety, and mission readiness.

Healthy Eating Index and Nutrition Biomarkers among Army Soldiers and Civilian Control Group Indicate an Intervention Is Necessary to Raise Omega-3 Index and Vitamin D and Improve Diet Quality.

Diet quality and nutrition status are important for optimal health and military performance. Few studies have simultaneously evaluated diet quality and biochemical markers of nutritional status of military service members. The Healthy Eating Index (HEI) can be used to assess dietary quality and adherence to federal nutrition guidelines. The aim of this study was to assess soldiers' diet quality and nutritional status and compare results to a civilian control group. METHODS: A cross-sectional study was conducted with 531 soldiers. A food frequency questionnaire was used to calculate HEI scores. A blood sample was collected for analysis of select nutrition biochemical markers. Non-parametric analyses were conducted to compare the diet quality and nutritional status of soldiers and controls. Differences in non-normally distributed variables were determined by using the Wilcoxon signed-rank test. RESULTS: Soldiers had an HEI score of 59.9 out of 100, marginally higher than the control group (55.4). Biochemical markers of interest were within normal reference values for soldiers, except for the omega-3 index and vitamin D. CONCLUSIONS: This study identified dietary components that need improvement and deficits in biochemical markers among soldiers. Improving diet quality and nutritional status should lead to better health, performance, and readiness of the force.
