The connection between POPs and Metabolic Syndrome
As the pioneer and global leader of Functional Medicine, the Institute of Functional Medicine leads and catalyses the efforts of a large and expanding Functional Medicine ecosystem, including providers, educators, payers, industry leaders, regulators, and influencers.
2023
Abstract
This IFM insight investigates the growing link between persistent organic pollutants (POPs) and increased rates of metabolic syndrome. There is evidence that POPs may also impair metabolic functioning of ‘normal weight’ individuals and not just those who are overweight or obese due to their potential impact on the gut microbiome. Underlying mechanisms are explored as well as the risks of eliminating POPs from the body. They review dietary approaches that may be targeted to support individuals with metabolic syndrome along with a high toxic burden in light of the ubiquity of POPs in our food environment.

Food Crops: Nutrient Fluctuations and Malnutrition
As the pioneer and global leader of Functional Medicine, the Institute of Functional Medicine leads and catalyses the efforts of a large and expanding Functional Medicine ecosystem, including providers, educators, payers, industry leaders, regulators, and influencers.
2022
Abstract
This article provides an insight into fluctuating nutrient levels within our food crops and why this might be happening, delving into the impact of climate change and farming methods on soil quality and subsequent nutrient availability. Research appears to be limited with respect to the level of pesticide exposure and health outcomes in organic food versus conventional food, but what has been noted is higher levels of polyphenols in organic crops which can reduce the risk of a wide range of chronic diseases. Having an awareness of the relationship between environmental change, food crops and human health can help practitioners to navigate the increasingly complex and hot topic of food sustainability with their clients.

Food systems, Health and Sustainability with Barbara Bray, MBE
Dr Rupy Aujla is an NHS medical doctor who reversed his heart condition using a food and lifestyle approach after diving deep into the literature and learning more about nutritional medicine. He started the Doctor’s Kitchen in 2015, as a way to teach others how they can cook their way to health and showcase that food is medicine.
2022
Abstract
In this podcast Rupy discusses a whole host of topics with Barbara Bray, from regenerative farming and farming techniques to food sustainability to food labelling and organic versus non organic food. Barbara is currently the director of Alo solutions, a consultancy that helps develop sustainable nutrition strategies for food businesses. She has a diverse background and has been awarded an MBE for services to food nutrition. Overall an interesting discussion looking through different lenses: the government, the nutritionist, the farmer, and the consumer. It is suggested that considering overall toxic load including environmental toxins might far outweigh the impact of ingesting pesticides through food.

Plain language summary
Recently, there has been an increase in organic food consumption. Among the specific foods included in worldwide dietary patterns that are organically produced is the chicken egg. The aim of this study was to synthesize the available evidence on the association between organic egg consumption and human health. This study is systematic review of three studies. This study shows that: - two of the studies reported favourable results in terms of higher serum carotenoid levels and lower levels of specific inflammatory markers associated with the consumption of organic eggs. - scientific evidence has thus far not focused on whether organic eggs are directly associated with health benefits but on the nutritional value of organic foods compared to conventional foods which in turn could lead to advantages for human health. Authors conclude organic eggs may have nutritional advantages over conventional or non-organic eggs, possibly related to the higher levels of carotenoids and the reduction in the inflammatory potential of the diet. However, their findings are limited thus no firm conclusions can be drawn about the benefits of organic eggs on human health.
Abstract
Consumption of organic foods has increased recently, but evidence about their potential health benefits is still limited. This systematic review aims to synthesize the available scientific evidence on the association between organic egg consumption and human health. We searched for peer-reviewed articles on this subject indexed in the MEDLINE, EMBASE, Web of Science and Cochrane Library databases from the inception date to April 13, 2022. This review was based on PRISMA guideline recommendations. Three studies on organic egg consumption in humans were included. After 8 weeks of consuming organic eggs, one randomized crossover trial found that participants had higher serum concentrations of the beta-carotene lutein compared to the period without consuming organic eggs. Moreover, in a cross-sectional study with nationally representative data from Americans over the age of 50, it was found that consumption of organic eggs was associated with lower levels of the inflammatory markers C-reactive protein and cystine C compared with conventional eggs. Finally, in a cohort of children aged 0 to 2 years, no significant association was observed between consuming organic eggs and the risk of eczema. In conclusion, the evidence about the potential benefits of organic egg consumption and human health is promising but still requires further research. A human research agenda is proposed based on laboratory studies pointing out that organic eggs have a more desirable nutritional profile than conventional eggs.

Plain language summary
Neurodegenerative diseases such as Alzheimer’s disease are without effective therapeutics. The aim of this study was to compare the effects of a precision medicine approach to historical controls in patients with mild cognitive impairment or early dementia. This study is a proof-of-concept study which recruited twenty-five patients with Alzheimer’s disease or mild cognitive impairment, aged between 50–76 years. Patients were treated for nine months with a personalised, precision medicine protocol that addressed each patient’s identified potentially contributory factors. Results show that a precision medicine approach to the cognitive decline of Alzheimer’s disease and mild cognitive impairment may be an effective strategy, especially with continued optimization over time. Authors conclude that their findings indicate that it is possible to reverse cognitive decline in mild cognitive impairment and early dementia with a personalised, precision medicine (/systems medicine) protocol. This is a small study that requires larger scale initiatives, including examining the practicalities of integrating this approach into healthcare systems.
Abstract
BACKGROUND Effective therapeutics for Alzheimer's disease are needed. However, previous clinical trials have pre-determined a single treatment modality, such as a drug candidate or therapeutic procedure, which may be unrelated to the primary drivers of the neurodegenerative process. Therefore, increasing data set size to include the potential contributors to cognitive decline for each patient, and addressing the identified potential contributors, may represent a more effective strategy. OBJECTIVE To determine whether a precision medicine approach to Alzheimer's disease and mild cognitive impairment is effective enough in a proof-of-concept trial to warrant a larger, randomized, controlled clinical trial. METHODS Twenty-five patients with dementia or mild cognitive impairment, with Montreal Cognitive Assessment (MoCA) scores of 19 or higher, were evaluated for markers of inflammation, chronic infection, dysbiosis, insulin resistance, protein glycation, vascular disease, nocturnal hypoxemia, hormone insufficiency or dysregulation, nutrient deficiency, toxin or toxicant exposure, and other biochemical parameters associated with cognitive decline. Brain magnetic resonance imaging with volumetrics was performed at baseline and study conclusion. Patients were treated for nine months with a personalized, precision medicine protocol, and cognition was assessed at t = 0, 3, 6, and 9 months. RESULTS All outcome measures revealed improvement: statistically significant improvement in MoCA scores, CNS Vital Signs Neurocognitive Index, and Alzheimer's Questionnaire Change score were documented. No serious adverse events were recorded. MRI volumetrics also improved. CONCLUSION Based on the cognitive improvements observed in this study, a larger, randomized, controlled trial of the precision medicine therapeutic approach described herein is warranted.

Plain language summary
Omega-3 fatty acids such as docosahexaenoic acid (DHA) are thought to be beneficial for the development of the fetal brain. Women with a singleton pregnancy at <21 weeks’ gestation enrolled in this multicentre, double-blind, randomised controlled trial to assess the fetal neurodevelopment effects of 800 mg/day, which they took until the birth of their children. A follow-up assessment was arranged when the children reached age seven to evaluate their neurodevelopment. Children of women who took DHA supplements showed increased risk scores on hyperactivity, behavioural problems that may impact daily activities, ADHD, peer relationships, Metacognition Indexes, Shift, Inhibit, Monitor, Working Memory, and Organization of Materials scales. Supplementing with high doses of DHA during pregnancy might not have any protective effects on neurodevelopment in women with high baseline DHA levels. However, further robust studies are required to confirm the results to determine the clinical applicability of DHA supplementation in pregnant women. Healthcare professionals can use the results of this study to understand the dose-dependent therapeutic application of DHA and its impact on fetal neurodevelopment.
Abstract
Docosahexaenoic acid (DHA) accumulates in the fetal brain during pregnancy and is thought to have a role in supporting neurodevelopment. We conducted a multicenter, double-blind, randomized controlled trial in women with a singleton pregnancy who were <21 weeks' gestation at trial entry. Women were provided with 800 mg DHA/day or a placebo supplement from trial entry until birth. When children reached seven years of age, we invited parents to complete the Strengths and Difficulties Questionnaire (SDQ), the Behavior Rating Inventory of Executive Function (BRIEF), and the Conners 3rd Edition Attention-Deficit Hyperactivity Disorder (ADHD) Index to assess child behavior and behavioral manifestations of executive dysfunction. There were 543 parent-child pairs (85% of those eligible) that participated in the follow-up. Scores were worse in the DHA group than the placebo group for the BRIEF Global Executive, Behavioral Regulation and Metacognition Indexes, and the Shift, Inhibit, Monitor, Working Memory, and Organization of Materials scales, as well as for the Conners 3 ADHD index, and the SDQ Total Difficulties score, Hyperactivity/Inattention score, and Peer Relationship Problems score. In this healthy, largely term-born sample of children, prenatal DHA supplementation conferred no advantage to childhood behavior, and instead appeared to have an adverse effect on behavioral functioning, as assessed by standardized parental report scales.

Plain language summary
The gluten-free diet (GFD) is a medical response for people with coeliac disease, a systemic autoimmune disorder for which GFD is the only available effective treatment. The aim of this study was to compare the consumption of organic products (as a whole and by food group) in individuals (partially or totally) avoiding gluten or not, and their places of food purchases of organic food. Results indicate a positive association between gluten avoidance and contribution of organic food to the diet. A gradient was also observed with total avoiders consuming more of organic food than partial avoiders. This contribution was higher for all types of products, except milk and dairy products. Furthermore, the results appear consistent with the motives reported by individuals avoiding gluten. Authors conclude that their findings underline a strong positive correlation between gluten avoidance and organic food consumption.
Abstract
The rising popular belief that gluten is unhealthy has led to growth in gluten avoidance in people without coeliac disease. Little information is available on their dietary profiles and their dietary behaviours. Our aim was to compare the consumption of organic foods between gluten avoiders and non-avoiders, and their places of food purchase. We described their sociodemographic and dietary profiles. The study population included participants of the NutriNet-Santé cohort who completed both a food exclusion questionnaire and an organic semi-quantitative FFQ (n 23 468). Food intake and organic food consumption ratios were compared using multivariable adjusted ANCOVA models. Associations between gluten avoidance and organic food consumption as well as places of food purchase were investigated with multivariable logistic regression. Participants avoiding gluten were more likely to be women and had a healthier dietary profile. Organic food consumption was higher among gluten avoiders (48·50 % of total diet for total avoiders, 17·38 % for non-avoiders). After adjustments for confounders, organic food consumption and purchase in organic stores were positively associated with gluten avoidance: adjusted OR (aOR)Q5 v.Q1 organic food = 4·95; 95 % CI 3·70, 6·63 and aORorganic stores v.supermarkets = 1·82; 95 % CI 1·42, 2·33 for total avoiders. Our study highlights that individuals avoiding gluten are high organic consumers and frequently purchase their foods in organic stores which propose an extended offer of gluten-free food. Further research is needed to determine the underlying common motivations and the temporality of the dietary behaviours of healthy people avoiding gluten.

Plain language summary
The food market is changing dynamically. New food production technologies are emerging, especially those with high and enriched nutritional value and functional food. The aim of this study was to determine the differences in the frequency, reasons, and barriers against buying organic food by residents of the Visegrád Group member states. Results indicate that: - the Poles and Hungarians buy organic food very often, whereas the largest percentages of Slovaks and Czechs do so rarely. - the most important reasons for choosing organic food in all V4 countries were the absence of genetically modified organisms, chemicals and preservatives. - high prices is the main barrier limiting the purchase of organic food. - the differences in the consumption of organic products in individual V4 countries may result from the actual differentiation or different interpretations of the definition of organic products and confusion with home and locally produced food. Authors conclude that to fully utilize the potential of the organic farming sector and organic aquaculture and to ensure their sustainable development, it is necessary to define the goals and activities to be implemented by the Minister of Agriculture in individual countries to produce organic food together with its promotion.
Abstract
This study aimed to determine the differences in the frequency of, reasons for, and barriers to purchasing organic food among the inhabitants of the Visegrád Group member states. The selection of the countries for the study was dictated by the fact that the countries of Central and Eastern Europe play the role of a niche market in the European organic food market. This research employed the method of a diagnostic survey and the discriminant function. A chi-squared test, ANOVA, and Fisher's Post Hoc LSD test were also used to present differences in individual groups. This research shows that respondents from Poland, the Czech Republic, Hungary and Slovakia were guided by similar behaviors regarding the purchase of organic food. However, the attitudes of the respondents slightly differed between countries. In the case of the reasons for choosing organic food, the most important thing was that it is non-genetically modified food, especially for Polish consumers. The following were also mentioned: lack of chemical compounds (Slovaks and Czechs), high health value of such food (Czechs and Slovaks), and excellent taste (Hungarians). The most critical barriers against purchasing are the price (Poles and Hungarians), difficult access (Poles and Hungarians), and the short expiry time of such products (Slovaks).

Plain language summary
Autism spectrum disorder (ASD) is characterized by neurodevelopmental differences in the brain that manifest in divergent social and communicative abilities and stereotyped behaviours. The prevalence of ASD diagnoses has risen sharply in recent years, possibly due to changes in diagnostics criteria, but this does not fully explain the increase. ASD has known genetic predispositions, but vulnerability factors, such as influences from the external environment, are thought to influence the development of the condition. Exposure to pesticides has been of interest here, as both human and rodent studies have demonstrated links between certain pesticides and ASD-like behaviours and diagnosis. This systematic review sought to summarize current knowledge from preclinical and epidemiological studies. It included 45 human and 16 preclinical studies from animal models, focusing on Organophosphates, Organochlorine, Pyrethroid, Neonicotinoid, Carbamate, and exposure to mixed pesticides. The anayisis yielded no clear conclusion as the complexity of influencing factors made the studies hard to summarize. I.e. different types of pesticides, exposure duration, exposure routes and methodologies used in the various studies. Another problem highlighted by the author is that it is impossible to look at pesticide exposure in isolation as it always co-exists with other factors that may be harmful or beneficial for the development of the nervous system. Such as lifestyle, socioeconomics, educational status, ethnicity, gender or genetics. However, evidence suggests that some compounds like Organophosphates, Organochlorine and Pyrethroid appear to have an impact on cognitive and behavioural functions in children following exposure. Yet, further clinical research is needed to draw firm conclusions on pesticide exposures in humans and ASD in general. Overall this review yields a comprehensive overview of various pesticides and their evidence on ASD. Whilst awaiting further research more solid conclusions may be drawn by focusing on specific compounds and their existing research
Abstract
Autism spectrum disorder (ASD) is a complex set of neurodevelopmental pathologies characterized by impoverished social and communicative abilities and stereotyped behaviors. Although its genetic basis is unquestionable, the involvement of environmental factors such as exposure to pesticides has also been proposed. Despite the systematic analyses of this relationship in humans, there are no specific reviews including both human and preclinical models. The present systematic review summarizes, analyzes, and discusses recent advances in preclinical and epidemiological studies. We included 45 human and 16 preclinical studies. These studies focused on Organophosphates (OP), Organochlorine (OC), Pyrethroid (PT), Neonicotinoid (NN), Carbamate (CM), and mixed exposures. Preclinical studies, where the OP Chlorpyrifos (CPF) compound is the one most studied, pointed to an association between gestational exposure and increased ASD-like behaviors, although the data are inconclusive with regard to other ages or pesticides. Studies in humans focused on prenatal exposure to OP and OC agents, and report cognitive and behavioral alterations related to ASD symptomatology. The results of both suggest that gestational exposure to certain OP agents could be linked to the clinical signs of ASD. Future experimental studies should focus on extending the analysis of ASD-like behaviors in preclinical models and include exposure patterns similar to those observed in human studies.
