A randomized parallel intervention study was conducted with male patients diagnosed with coronary heart disease. Participants were assigned to three groups: Group A abstained from alcohol (n=20), Group B consumed red wine (n=21) and Group C (n=16) consumed an alcoholic beverage without wine micro-constituents. Biological samples were collected at baseline, 4 and 8 weeks. Enzyme activities of acetyl-CoA:lyso-PAF acetyltransferase (LysoPAF-AT), CDP-choline:1-alkyl-2-acetyl-sn-glycerol cholinephosphotransferase (PAF-CPT), PAF-acetylhydrolase (PAF-AH) in leukocyte homogenates, serum lipoprotein associated phospholipase-A2 (LpPLA2) and plasma markers of thrombosis were measured. PAF-, adenosine diphosphate (ADP)-, and collagen- induced platelet aggregation was measured in human platelet rich plasma.

Red wine consumption led to 15.3% reduction in LysoPAF-AT activity at 4 weeks (p=0.008) compared to baseline and Group A (p=0.01). PAF-CPT activity was reduced by 11.1% at 8 weeks (p=0.04) compared to baseline, and by 24.9% compared to Group C (p=0.02). PAF-AH activity was reduced by 36.2% at 8 weeks compared to baseline (p=0.001) and compared to Group A (p<0.000) and Group C (p=0.009). Fibrinogen levels in Group B reduced by 6-9% at 4 (p=0.04) and 8 weeks (p=0.01) compared to baseline while d-dimer in Group C increased by 16.1% at 8 weeks (p=0.005) compared to baseline. Platelet aggregation against PAF and collagen was reduced in Group B (82.6% and 35.4%, respectively), and in Group C (158.4% and 37.1%, respectively) compared to baseline and Group A (p<0.05).

In conclusion, moderate wine consumption improved the activity of PAF-metabolism enzymes regardless of ethanol and reduced platelet aggregation probably through mechanisms different from those of ethanol.

Insulin-like growth factor 1 (IGF-1) is an important growth factor in childhood. We aimed to investigate the impact of food supplements for treatment of moderate acute malnutrition (MAM) on serum IGF-1 (sIGF-1). Secondary analysis of a randomized 2×2×3 factorial nutrition trial was performed. Children aged 6-23 months with MAM received 2093 kJ/day as lipid-based nutrient supplement (LNS) or corn-soy blend (CSB), containing either dehulled soy or soy isolate and different quantities of dried skimmed milk (0%, 20% or 50% of total protein) for 12 weeks. The trial was double-blind with regard to soy and milk, but not to matrix (LNS vs. CSB). sIGF-1 was measured at inclusion and after 12 weeks supplementation. Of 1609 children enrolled, 1455 (90%) had sIGF-1 measured at both time points. During supplementation sIGF-1 increased 6.7 (95%CI 6.1; 7.3) ng/ml compared with an expected age-dependent decrease of 0.3 (95%CI 0.2; 0.4) ng/ml. Children who received LNS vs. CSB had lower increase in sIGF-1 (-8%, 95%CI -12; -3). The effect of LNS was partly attenuated when sIGF-1 was corrected for inflammation. Children who received soy isolate compared with dehulled soy had higher increase in sIGF-1 (6%, 95%CI 1; 12). Milk content did not affect sIGF-1. Overall, sIGF-1 increased during supplementation. The lower increase with LNS vs. CSB was only partly explained by increased inflammation with LNS, and needs further investigation. Isolate vs. dehulled soy led to a higher increase which may be due to antinutrients in dehulled soy.

A co-relation between Schistosoma japonicum (Sj) and liver cancer (LC) in humans has been reported in the literature; however, this association is circumstantial. Due to the inconclusive nature of this association, the International Agency for Research on Cancer has placed Sj in Group 2B for LC, signifying it to be a ‘possible carcinogen’. Many epidemiological, pathological and clinical studies have identified multiple factors, linked with Sj infection, which can lead to liver carcinogenesis. These factors include chronic inflammation in response to deposited eggs (which leads to fibrosis, cirrhosis and chromosomal instability at cellular level), hepatotoxic effects of egg-antigens, co-infection with hepatitis viruses, and up-regulation of glycolysis linked genes among others which predisposes hepatic tissue towards malignant transformation. The objective of this work is to present the current understanding on the association of Sj infection with LC. Mechanisms and factors linked with Sj infection that can lead to LC are emphasized, along with measures to diagnose and treat it. A comparison of liver carcinogenesis is also provided for cases linked with and independent of Sj infection. It appears that Sj, alone or with another carcinogen, is an important factor in liver carcinogenesis, but further studies are warranted to conclusively label ‘infection with Sj alone’ as a liver carcinogen.

Mastitis in dairy cows is an important factor restricting the healthy development of dairy industry. Natural extracts have become a research hotspot to alleviate and prevent diseases because of their unique properties. The purpose of this study was to investigate the effects of resveratrol (RES) on the mitochondrial biosynthesis, antioxidation, and anti-inflammatory in bovine mammary epithelial cells (BMECs) and its mechanism involved. Blood samples were collected from six healthy cows and six mastitis affected cows, respectively, and lipopolysaccharide (LPS) was used to treat BMECs to construct inflammation models, gene interference is achieved by transfection. The results showed that messenger RNA (mRNA) expression of peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) was down-regulated and mitochondrial biogenesis-related gene expression was disrupted in the blood of mastitis cows and LPS-induced BMECs. RES is the best active substance to activate PGC-1α. The addition of RES can effectively alleviate the production of BMECs reactive oxygen species (ROS) and mitochondrial damage induced by LPS, and improve the antioxidation and anti-inflammatory ability, while the alleviation effect of RES is inhibited after interfering with protein kinase AMP-activated catalytic subunit α 1 (PRKAA1). In summary, our study emphasizes that PRKAA1 is a key gene mediating the activation of PGC-1α by RES, which regulates mitochondrial biosynthesis, inhibits ROS release, attenuates mitochondrial damage, and improves mitochondrial antioxidant capacity through the activation of PGC-1α by PRKAA1, thus attenuating the inflammatory response in BMECs.

Chia seeds have gained attention for their potential anti-inflammatory properties, which may be attributed to their high content of omega-3 fatty acids, dietary fibre, and antioxidants. This study aims to provide an overview of the current understanding regarding the effects of chia seeds on inflammatory markers, specifically C-reactive protein (CRP), interleukin-6 (IL-6), and tumour necrosis factor-alpha (TNF-α). A comprehensive literature search was conducted on PubMed, Scopus, Web of Science, Cochrane, and Google Scholar up to June 2024. Randomized controlled trials (RCTs) assessing the effect of chia seed on CRP or/and IL-6 or/and TNF-α. Data were extracted and analysed using a random-effects model, and reported as weighted mean differences (WMD) with 95% confidence intervals (CI). Subgroup and sensitivity analyses were also performed. Four RCTs involving 210 participants were included in the meta-analysis. The results showed that chia consumption significantly decreased CRP (WMD: –0.64 mg/dl; 95% CI: –1.24, –0.04; P = 0.03). But it had no significant effect on IL-6 (WMD: 0.29 pg/dl; 95% CI: –0.40, 0.98; P = 0.41), and TNF-α (WMD: 0.05%; 95% CI: –0.21 to 0.30; P = 0.72). Chia consumption can significantly decrease CRP, but no significant effect was observed on IL-6 and TNF-α. To prove our findings, more studies with a larger sample size are needed.

Metabolic dietary patterns, including the Empirical Dietary Index for Hyperinsulinaemia (EDIH) and Empirical Dietary Inflammatory Pattern (EDIP), are known to impact multiple chronic diseases, but the role of the colonic microbiome in mediating such relationships is poorly understood. Among 1,610 adults with faecal 16S rRNA data in the TwinsUK cohort, we identified the microbiome profiles for EDIH and EDIP (from food frequency questionnaires) cross-sectionally using elastic net regression. We assessed the association of the dietary pattern-related microbiome profile scores with circulating biomarkers in multivariable-adjusted linear regression. In addition, we used PICRUSt2 to predict biological pathways associated with the enriched microbiome profiles, and further screened pathways for associations with the dietary scores in linear regression analyses. Microbiome profile scores developed with 32 (EDIH) and 15 (EDIP) genera were associated with higher insulin and homeostatic model assessment of insulin resistance. Six genera were associated with both dietary scores: Ruminococcaceae_UCG-008, Lachnospiraceae_UCG-008, Defluviitaleaceae_UCG-011 Anaeroplasma, inversely and Negativibacillus, Streptococcus, positively. Further, pathways in fatty acid biosynthesis, sugar acid degradation, and mevalonate metabolism were associated with insulinaemic and inflammatory diets. Dietary patterns that exert metabolic effects on insulin and inflammation may influence chronic disease risk by modulating gut microbial composition and function.

A positive association has been demonstrated between consumption of sucrose-sweetened beverages and the prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD). Since the administration of 30 % sucrose in the drinking water (sucrose-rich diet (SRD)) to rats has proven to be a good model of systemic insulin resistance, the aim of our study was to analyse the effect of caloric restriction applied on SRD-treated rats by switching back to a standard diet, on liver morphology, function and metabolism. Consumption of an SRD causes a metabolic shift towards gluconeogenesis and fatty acid synthesis leading to an increase in TAG levels in plasma and in the liver that were associated with a decrease in insulin sensitivity. Moreover, our results show that animals fed an SRD develop steatohepatitis characterised by the generation of oxidative stress, endoplasmic reticulum (ER) stress, inflammation and apoptosis. Although no histological changes were observed after a 2-week caloric restriction, key pathways associated with the progression of MASLD as inflammation, ER stress and apoptosis were slowed down. Notably, this 2-week intervention also increased liver insulin sensitivity (evaluated by AKT activity in this tissue) and drove the lipid metabolic profile towards oxidation, thus lowering circulating TAG levels. In summary, the present study uncovers underlying mechanisms affected, and their metabolic consequences, during the first stages of the phenotypic reversal of steatohepatitis by switching back to a standard diet after receiving sucrose-sweetened water for several weeks.

Lipids play an important role in human nutrition. Although adequate lipid consumption is necessary for an optimal functioning of the human body, overconsumption of saturated fatty acids can lead to postprandial hypertriglyceridaemia, which triggers the development of atherosclerosis. Important parameters that impact postprandial lipaemia and inflammation are related to the matrix structure and the fat-soluble micronutrient profile of ingested foods/lipids, but the specific effect of these parameters should be further studied, as most of the available studies evaluate their effect at fasting state. This review specifically explores the effects of food structure and fat-soluble micronutrients, from either micronutrient-rich foods or supplements, on postprandial hypertriglyceridaemia and inflammation. The review also highlights the potential of emerging biomarkers such as miRNAs or circulating microvesicles, as an alternative to the widely use biomarkers (e.g. low-density lipoproteins or blood concentration of pro-inflammatory cytokines), to identify inflammation associated with postprandial hypertriglyceridaemia at early stages.

This study evaluated the effect of green tea extract and metformin and its interaction on markers of oxidative stress and inflammation in overweight women with insulin resistance. After screening, 120 women were randomly allocated in 4 groups: Placebo (PC): 1g of microcrystalline cellulose/day; Green tea (GT): 1 g (558 mg polyphenols) of standardized dry extract of green tea/day and 1 g of placebo/day; Metformin (MF): 1 g of metformin/day and 1 g of placebo/day; Green Tea and Metformin (GTMF): 1 g (558 mg polyphenols) and 1 g of metformin/day. All groups were followed-up for 12 weeks with assessment of oxidative damage to lipids and proteins, specific activity of antioxidant enzymes and inflammatory cytokine serum levels. The association of green tea with metformin significantly reduced IL-6 (GTMF: –29.7((–62.6)–20.2))(p = 0.004). Green tea and metformin isolated reduced TNF-α (GT: –12.1((–18.0)–(–3.5)); MF: –24.5((–38.60)–(–4.4)) compared to placebo (PB: 13.8 (1.2–29.2))(P < 0.001). Also, isolated metformin reduced TGF-β (MF: –25.1((–64.4)–0.04)) in comparison to placebo (PB: 6.3((–1.0)–16.3))(p = 0.038). However, when combined, their effects were nullified either for TNF-α (GTMF: 6.0((–5.7)–23.9) and for TGF-β (GTMF: –1.8((–32.1)–8.5). This study showed that there is a drug-nutrient interaction between green tea and metformin that is dependent on the cytokine analyzed.

The antioxidant capacity and the inflammatory potential of diet during pregnancy may represent a prevention opportunity for allergic and respiratory diseases. We aimed to investigate the associations between the antioxidant and the inflammatory potential of maternal diet in the last 3 months of pregnancy with allergic and respiratory diseases in children. Analyses were performed on 9679 mother–child pairs from the ELFE birth cohort. The dietary total antioxidant capacity (DTAC), without coffee, was estimated with the Trolox equivalent antioxidant capacity (TEAC), the total radical trapping antioxidant parameter (TRAP) and the ferric reducing-antioxidant power (FRAP). The inflammatory potential of the maternal diet was assessed by the energy-adjusted dietary inflammatory index (E-DII). Allergic and respiratory diseases in children up to 5·5 years were considered jointly through five allergic and respiratory multimorbidity clusters (‘asymptomatic’ - reference, ‘early wheeze without asthma’, ‘asthma only’, ‘allergies without asthma’ and ‘multi-allergic’). Multinomial logistic regressions were performed and adjusted for main confounders. A diet with a higher antioxidant potential was associated with a lower risk of belonging to the ‘early wheeze without asthma’ cluster (aOR (95 % CI) = 0·95 (0·90, 0·99) per sd of TEAC score). A higher E-DII was associated with a higher risk of belonging to the ‘asthma only’ cluster (aOR (95 % CI) = 1·09 (1·00, 1·19) per sd). No association was found with the ‘allergies without asthma’ or ‘multi-allergic’ clusters. An antioxidant-rich diet during pregnancy was associated with better respiratory health, while a pro-inflammatory diet was associated with poorer respiratory health in children up to 5·5 years, though the associations were weak.

Epidemiological and clinical trial evidence indicates that n-6 polyunsaturated fatty acid (PUFA) intake is cardioprotective. Nevertheless, claims that n-6 PUFA intake promotes inflammation and oxidative stress prevail. This narrative review aims to provide health professionals with an up-to-date evidence overview to provide the requisite background to address patient/client concerns about oils containing predominantly unsaturated fatty acids (UFA), including MUFA and PUFA. Edible plant oils, commonly termed vegetable oils, are derived from vegetables, nuts, seeds, fruits and cereal grains. Substantial variation exists in the fatty acid composition of these oils; however, all are high in UFA, while being relatively low in saturated fatty acids (SFA), except for tropical oils. Epidemiological evidence indicates that higher PUFA intake is associated with lower risk of incident CVD and type 2 diabetes mellitus (T2DM). Additionally, replacement of SFA with PUFA is associated with reduced risk of CVD and T2DM. Clinical trials show higher intake of UFA from plant sources improves major CVD risk factors, including reducing levels of atherogenic lipids and lipoproteins. Importantly, clinical trials show that increased n-6 PUFA (linoleic acid) intake does not increase markers of inflammation or oxidative stress. Evidence-based guidelines from authoritative health and scientific organisations recommend intake of non-tropical vegetable oils, which contain MUFA and n-6 PUFA, as part of healthful dietary patterns. Specifically, vegetable oils rich in UFA should be consumed instead of rich sources of SFA, including butter, tallow, lard, palm and coconut oils.

Inflammation and infections such as malaria affect micronutrient biomarker concentrations and hence estimates of nutritional status. It is unknown whether correction for C-reactive protein (CRP) and α1-acid glycoprotein (AGP) fully captures the modification in ferritin concentrations during a malaria infection, or whether environmental and sociodemographic factors modify this association. Cross-sectional data from eight surveys in children aged 6–59 months (Cameroon, Cote d’Ivoire, Kenya, Liberia, Malawi, Nigeria and Zambia; n 6653) from the Biomarkers Reflecting Inflammation and Nutritional Determinants of Anaemia (BRINDA) project were pooled. Ferritin was adjusted using the BRINDA adjustment method, with values < 12 μg/l indicating iron deficiency. The association between current or recent malaria infection, detected by microscopy or rapid test kit, and inflammation-adjusted ferritin was estimated using pooled multivariable linear regression. Age, sex, malaria endemicity profile (defined by the Plasmodium falciparum infection prevalence) and malaria diagnostic methods were examined as effect modifiers. Unweighted pooled malaria prevalence was 26·0 % (95 % CI 25·0, 27·1) and unweighted pooled iron deficiency was 41·9 % (95 % CI 40·7, 43·1). Current or recent malaria infection was associated with a 44 % (95 % CI 39·0, 52·0; P < 0·001) increase in inflammation-adjusted ferritin after adjusting for age and study identifier. In children, ferritin increased less with malaria infection as age and malaria endemicity increased. Adjustment for malaria increased the prevalence of iron deficiency, but the effect was small. Additional information would help elucidate the underlying mechanisms of the role of endemicity and age in the association between malaria and ferritin.

Emerging evidence suggests that low-grade systemic inflammation plays a key role in altering brain activity, behaviour and affect. Modulation of the gut microbiota using prebiotic fibre offers a potential therapeutic tool to regulate inflammation, mediated via the production of short-chain fatty acids (SCFA). However, the impact of prebiotic consumption on affective symptoms and the possible contribution from inflammation, gut symptoms and the gut microbiome are currently underexamined. In this 12-week study, the effects of a diverse prebiotic blend on inflammation, gut microbiota profiles and affective symptoms in a population with metabolic syndrome (MetS) were examined. Sixty males and females with MetS meeting the criteria for MetS were randomised into a treatment group (n 40), receiving 10 g per day of a diverse prebiotic blend and healthy eating advice, and a control group (n 20), receiving healthy eating advice only. Our results showed a significant reduction in high sensitivity C-reactive protein (hs-CRP) in the treatment (–0·58 [–9·96 to–2·63]) compared with control (0·37 [–3·64 to–3·32]), alongside significant improvements in self-reported affective scores in the treatment compared with the control group. While there were no differences in relative abundance between groups at week 12, there was a significant increase from baseline to week 12 in fecal Bifidobacterium and Parabacteroides in the treatment group, both of which are recognised as SCFA producers. Multivariate regression analyses further revealed an association between gastrointestinal symptoms and hs-CRP with affective scores. Together, this study provides preliminary support for a diverse prebiotic blend for mood, stress and anxiety.

An anti-inflammatory diet is characterised by incorporating foods with potential anti-inflammatory properties, including fruits, vegetables, whole grains, nuts, legumes, spices, herbs and plant-based protein. Concurrently, pro-inflammatory red and processed meat, refined carbohydrates and saturated fats are limited. This article explores the effects of an anti-inflammatory diet on non-communicable diseases (NCD), concentrating on the underlying mechanisms that connect systemic chronic inflammation, dietary choices and disease outcomes. Chronic inflammation is a pivotal contributor to the initiation and progression of NCD. This review provides an overview of the intricate pathways through which chronic inflammation influences the pathogenesis of conditions including obesity, type II diabetes mellitus, CVD, autoinflammatory diseases, cancer and cognitive disorders. Through a comprehensive synthesis of existing research, we aim to identify some bioactive compounds present in foods deemed anti-inflammatory, explore their capacity to modulate inflammatory pathways and, consequently, to prevent or manage NCD. The findings demonstrated herein contribute to an understanding of the interplay between nutrition, inflammation and chronic diseases, paving a way for future dietary recommendations and research regarding preventive or therapeutic strategies.
