Fish oil supplements, oxidative status, and compliance behaviour: Regulatory challenges and opportunities.

ABSTRACT:

Background

Fish oil supplements that are rich in omega-3 long-chain polyunsaturated fatty acids (n-3 PUFAs). PUFAs are among the most widely-used dietary supplements globally, and millions of people consume them regularly. There have always been public concerns that these products should be guaranteed to be safe and of good quality, especially as these types of fish oil supplements are extremely susceptible to oxidative degradation.

Objectives

The aim of the current study is to investigate and examine the oxidation status of dietary supplements containing fish oils and to identify important factors related to the oxidation status of such supplements available in the United Arab Emirates (UAE).

Methods

A total of 44 fish oil supplements were analysed in this study. For each product, the oxidative parameters peroxide value (PV), anisidine value (AV), and total oxidation (TOTOX) were calculated, and comparisons were made with the guidelines supplied by the Global Organization for EPA and DHA Omega-3s (GOED). Median values for each of the above oxidative parameters were tested using the Kruskal-Wallis and Mann-Whitney U tests. P values < 0.05 were chosen as the statistically significant boundary.

Results

The estimate for the average PV value was 6.4 with a 95% confidence interval (CI) [4.2-8.7] compared to the maximum allowable limit of 5 meq/kg. The estimate for the average P-AV was 11 with a 95% CI [7.8-14.2] compared to the maximum allowable limit of 20. The estimate for the average TOTOX value was 23.8 meq/kg with a 95% CI [17.4-30.3] compared to the maximum allowable limit of 26 according to the GOED standards.

Conclusion

This research shows that most, although not all, of the fish oil supplements tested are compliant with the GOED oxidative quality standards. Nevertheless, it is clear that there should be a high level of inspection and control regarding authenticity, purity, quality, and safety in the processes of production and supply of dietary supplements containing fish oils.

Project description:ImportanceOne in 5 US adults older than 60 years takes fish oil supplements often for heart health despite multiple randomized clinical trials showing no data for cardiovascular benefit for supplement-range doses. Statements on the supplement labels may influence consumer beliefs about health benefits.ObjectivesTo evaluate health claims made on the labels of fish oil supplements in the US, and to examine doses of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in commonly available formulations.Design, setting, and participantsThis cross-sectional study used data from labels of on-market fish oil (and nonfish ω-3 fatty acid) supplements obtained from the National Institutes of Health Dietary Supplement Label Database. The study was conducted and data analyzed from February to June 2022.Main outcome and measuresThe frequency and types of health claims made on fish oil labels (US Food and Drug Administration [FDA]-reviewed qualified health claim vs a structure/function claim) and the organ system referenced were evaluated. The total daily doses of combined EPA and DHA (EPA+DHA) were assessed for supplements from 16 leading manufacturers and retailers.ResultsAcross 2819 unique fish oil supplements, 2082 (73.9%) made at least 1 health claim. Of these, only 399 (19.2%) used an FDA-approved qualified health claim; the rest (1683 [80.8%]) made only structure/function claims (eg, "promotes heart health"). Cardiovascular health claims were the most common (1747 [62.0%]). Across 16 leading brands/manufacturers, 255 fish oil supplements were identified. Among these, substantial variability was found in the daily dose of EPA (median [IQR], 340 [135-647] mg/d), DHA (median [IQR], 270 [140-500] mg/d), and total EPA+DHA (median [IQR], 600 [300-1100] mg/d). Only 24 of 255 supplements (9.4%) evaluated contained a daily dose of 2 g or more EPA+DHA.ConclusionsResults of this cross-sectional study suggest that the majority of fish oil supplement labels make health claims, usually in the form of structure/function claims, that imply a health benefit across a variety of organ systems despite a lack of trial data showing efficacy. Significant heterogeneity exists in the daily dose of EPA+DHA in available supplements, leading to potential variability in safety and efficacy between supplements. Increasing regulation of dietary supplement labeling may be needed to prevent consumer misinformation.

Project description:Interpersonal violence, which includes child abuse and neglect, youth violence, intimate partner violence, sexual violence, and elder abuse, affects millions of US residents each year. However, surveillance systems, programs, and policies to address violence often lack broad, cross-sector collaboration, and there is limited awareness of effective strategies to prevent violence.To describe the burden of interpersonal violence in the United States, explore challenges to violence prevention efforts and to identify prevention opportunities.We reviewed data from health and law enforcement surveillance systems including the National Vital Statistics System, the Federal Bureau of Investigation's Uniform Crime Reports, the US Justice Department's National Crime Victimization Survey, the National Survey of Children's Exposure to Violence, the National Child Abuse and Neglect Data System, the National Intimate Partner and Sexual Violence Survey, the Youth Risk Behavior Surveillance System, and the National Electronic Injury Surveillance System-All Injury Program.Homicide rates have decreased from a peak of 10.7 per 100,000 persons in 1980 to 5.1 per 100,000 in 2013. Aggravated assault rates have decreased from a peak of 442 per 100,000 in 1992 to 242 per 100,000 in 2012. Nevertheless, annually, there are more than 16,000 homicides and 1.6 million nonfatal assault injuries requiring treatment in emergency departments. More than 12 million adults experience intimate partner violence annually and more than 10 million children younger than 18 years experience some form of maltreatment from a caregiver, ranging from neglect to sexual abuse, but only a small percentage of these violent incidents are reported to law enforcement, health care clinicians, or child protective agencies. Moreover, exposure to violence increases vulnerability to a broad range of mental and physical health problems over the life course; for example, meta-analyses indicate that exposure to physical abuse in childhood is associated with a 54% increased odds of depressive disorder, a 78% increased odds of sexually transmitted illness or risky sexual behavior, and a 32% increased odds of obesity. Rates of violence vary by age, geographic location, sex, and race/ethnicity, and significant disparities exist. Homicide is the leading cause of death for non-Hispanic blacks from age 1 through 44 years, whereas it is the fifth most common cause of death among non-Hispanic whites in this age range. Additionally, efforts to understand, prevent, and respond to interpersonal violence have often neglected the degree to which many forms of violence are interconnected at the individual level, across relationships and communities, and even intergenerationally. The most effective violence prevention strategies include parent and family-focused programs, early childhood education, school-based programs, therapeutic or counseling interventions, and public policy. For example, a systematic review of early childhood home visitation programs found a 38.9% reduction in episodes of child maltreatment in intervention participants compared with control participants.Progress has been made in reducing US rates of interpersonal violence even though a significant burden remains. Multiple strategies exist to improve violence prevention efforts, and health care providers are an important part of this solution.
