The Impact

Considerable data is available on the effect of carbohydrate (carb) quantity on CVD risk factors but data for carb quality is limited. Our objective was to determine the relative comparability for an isocaloric exchange of unrefined-carb (endosperm+germ+bran, e.g., whole wheat flour), refined-carb (endosperm only, e.g., white flour) and simple-carb (sucrose, e.g., high fructose corn syrup), on cardiometabolic risk factors and the gut microbiome. All foods/beverages (60%E total carb, 15%E protein, 27%E fat [7%E SFA, 10%E MUFA, 10%E PUFA], 80mg cholesterol/1000 kcal) were provided to study subjects (n=11 men and women, 65 years, BMI 27.5 kg/m 2 , LDL-C ≥100 mg/dL) for 5 weeks (randomized, single-blind, cross-over design). Body weight was maintained constant. At the end of each diet phase plasma lipid profile, inflammatory factors and glucose homeostasis were determined using standard methods. Fecal microbiota taxa was characterized by 16S rRNA sequencing and data analyzed using QIIME and PathoScope. Plasma LDL-C levels differed among diets (125 ± 29 mg/dL b , 129 ± 29 mg/dL a,b and 136 ± 24 mg/dL a , unrefined-, simple- and refined-carb , respectively). Carb quality had no significant effect on HDL-C, TG, FFA, glucose, insulin, CRP or IL-6 levels. There were 21 genera that had a mean relative abundance (RA) of ≥1% and 4 genera (Roseburia, Oscillospira, Ruminococcus and Coprococcus) varied significantly across diets but after multiple testing adjustment, only Roseburia RA variations remained significant ( 2.58% a , 0.99% b , and 0.81% b , unrefined-, simple- and refined-carb , respectively). Interesting trends were observed between the RA of the following genera and plasma lipids: Roseburia was negatively associated with LDL-C (r=0.28, p=0.097) and HDL-C (r=-0.39, p=0.022); Oscillospira was negatively associated with TG (r=-0.53, p=0.097), and Anaerostipes was positively associated with TG (r=0.40, p=0.0585) levels. These data suggest that carb quality alters the RA of butyrate-producing bacteria, presumably leading to higher short chain fatty acid production, with subsequent alterations in plasma lipids. This study provides novel information about the impact of carb quality on the phylogenetic structure and functional capacity of the fecal microbiome.

Introduction: Whether plasma lipid levels are associated with stroke risk remains controversial, with even less data for American blacks versus whites. Hypothesis: We hypothesized that abnormal lipid levels are not associated with stroke incidence in either blacks or whites. Methods: The REasons for Geographic And Racial Differences in Stroke (REGARDS) study recruited 30,283 black and white individuals aged 45+ from the contiguous U.S. between 2003 to 2007, participants with a history of stroke at baseline were excluded. Participants were followed until 2018 for stroke events following the WHO definition and confirmed by review of medical records. The association of lipid measures with stroke were assessed using Cox regression models adjusted for traditional CVD risk factors and an age-x-race interaction term. Results: With 27,714 participants (mean age 64.85± 9.43, 59.5% white and 55.4% female), over a median of 11 years of follow up, 1,415 stroke events occurred, of which 599 among blacks. After adjusting for traditional stroke risk factors, there were modest associations between higher total cholesterol and higher LDL, but not higher triglycerides, with stroke risk. There was no evidence of a race interaction. Overall, HDL levels were not associated with stroke risk. However, when stratified by race, whites had a reduced risk of stroke with higher HDL-C, whereas no association was seen among blacks (p-interaction 0.09). Conclusion: In REGARDs, there was a modest association of cholesterol measures with stroke risk. The association for HDL with stroke may be influenced by race, with a less strong association among blacks than among whites.

Abstract Background Long-term heavy coffee consumption may adversely affect individuals’ cardiovascular disease (CVD) risk. As hyperlipidemia is a well-established contributor to CVD, we investigated the association between habitual coffee intake and plasma lipid profile. Methods We used data from up to 362,571 UK Biobank participants to examine associations between coffee intake and plasma lipid profiles, including LDL-C, HDL-C, total-C, triglycerides, ApoA1 and ApoB. Inverse variance weighted mendelian randomization (MR) was used to interrogate the causal nature of coffee-lipid associations, complemented by pleiotropy-robust methods, including MR-median, MR-Mode, MR-PRESSO and MR-Egger. Results We observed positive dose-dependent associations between self-reported coffee intake and plasma concentration of LDL-C, ApoB and total-C, with the highest lipid levels seen among participants drinking >6 cups/day (Plinear trend≤1.97E-57 for all). Genetic instrument for coffee intake was robustly associated with self-reported intake in the UK Biobank (F-statistic = 416). One cup increase in genetically instrumented intake was associated with 0.07 mmol/L (95%CI 0.03 to 0.12), 0.02 g/L (95%CI 0.01 to 0.03), and 0.09 mmol/L (95%CI 0.04 to 0.14) increase in LDL-C, ApoB, and total-C, respectively. Pleiotropy-robust methods provided largely consistent results albeit with greater imprecision when using MR-Egger. Conclusions Our phenotypic and genetic analysis consistently suggests that long-term heavy coffee consumption can lead to unfavourable lipid profile, which could potentially increase individuals’ risk for CVD. Individuals with elevated cholesterol may need to reduce their daily coffee intake. Key messages Our study provides evidence that long-term heavy coffee consumption can lead to unfavourable lipid profile.

The current study focused exclusively on evaluating the effects of replacing corn with olive cake meal (OCM) in the diet of broilers on their growth performance, abdominal fat, selected plasma parameters, and muscle fatty acid (FA) content. A total of 480 one-day-old male broiler chickens (Ross 308) were divided into four treatment groups with 12 replicates/treatment. The control group was fed the base diet, whereas the second to fourth groups were fed diets of corn with 5%, 10%, and 20% contents of OCM, respectively. Broilers fed with the 5% and 10% OCM diets showed better body weight (p = 0.04) and feed conversion ratio than the 20% OCM group (p < 0.048). Both nitrogen retention and ether extract digestibility were not improved by replaced corn with OCM. Replacing corn with OCM led to a decreased abdominal fat percentage (p = 0.023) compared with the control group. Birds in the OCM groups showed the lowest total cholesterol values (p = 0.038). The breast muscle (musculus pectoralis superficialis) content of oleic and linoleic, linolenic, and arachidonic acids was significantly high in birds fed with OCM diets. However, their palmitic acid level was significantly decreased. Vitamin E was increased by increasing the OCM level. Thus, we concluded that replacing corn with OCM, especially at a 10% level, is more effective than other replacement levels in improving growth performance, plasma lipid profile, and muscle FA content, as well as in causing a reduction in abdominal fat in broilers.

ABSTRACTThere is some evidence supporting the beneficial effects of a Paleolithic diet (PD) on cardiovascular disease (CVD) risk factors. This diet advises consuming lean meat, fish, vegetables, fruits, and nuts and avoiding intake of grains, dairy products, processed foods, and added sugar and salt. This study was performed to assess the effects of a PD on CVD risk factors including anthropometric indexes, lipid profile, blood pressure, and inflammatory markers using data from randomized controlled trials. A comprehensive search was performed in the PubMed, Scopus, ISI Web of Science, and Google Scholar databases up to August 2018. A meta-analysis was performed using a random-effects model to estimate the pooled effect size. Meta-analysis of 8 eligible studies revealed that a PD significantly reduced body weight [weighted mean difference (WMD) = −1.68 kg; 95% CI: −2.86, −0.49 kg], waist circumference (WMD = −2.72 cm; 95% CI: −4.04, −1.40 cm), BMI (in kg/m2) (WMD = −1.54; 95% CI: −2.22, −0.87), body fat percentage (WMD = −1.31%; 95% CI: −2.06%, −0.57%), systolic (WMD = −4.75 mm Hg; 95% CI: −7.54, −1.96 mm Hg) and diastolic (WMD = −3.23 mm Hg; 95% CI: −4.77, −1.69 mm Hg) blood pressure, and circulating concentrations of total cholesterol (WMD = −0.23 mmol/L; 95% CI: −0.42, −0.04 mmol/L), triglycerides (WMD = −0.30 mmol/L; 95% CI: −0.55, −0.06 mmol/L), LDL cholesterol (WMD = −0.13 mmol/L; 95% CI: −0.26, −0.01 mmol/L), and C-reactive protein (CRP) (WMD = −0.48 mg/L; 95% CI: −0.79, −0.16 mg/L) and also significantly increased HDL cholesterol (WMD = 0.06 mmol/L; 95% CI: 0.01, 0.11 mmol/L). However, sensitivity analysis revealed that the overall effects of a PD on lipid profile, systolic blood pressure, and circulating CRP concentrations were sensitive to removing some studies and to the correlation coefficients, hence the results must be interpreted with caution. Although the present meta-analysis revealed that a PD has favorable effects on CVD risk factors, the evidence is not conclusive and more well-designed trials are still needed.

The Impact

IntroductionCardiovascular disease (CVD) risk factors are increasing in sub-Saharan Africa. The impact of these risk factors on future CVD outcomes and burden is poorly understood. We examined the magnitude of modifiable risk factors, estimated future CVD risk and compared results between three commonly used 10-year CVD risk factor algorithms and their variants in four African countries.MethodsIn the Africa-Wits-INDEPTH partnership for Genomic studies (the AWI-Gen Study), 10 349 randomly sampled individuals aged 40–60 years from six sites participated in a survey, with blood pressure, blood glucose and lipid levels measured. Using these data, 10-year CVD risk estimates using Framingham, Globorisk and WHO-CVD and their office-based variants were generated. Differences in future CVD risk and results by algorithm are described using kappa and coefficients to examine agreement and correlations, respectively.ResultsThe 10-year CVD risk across all participants in all sites varied from 2.6% (95% CI: 1.6% to 4.1%) using the WHO-CVD lab algorithm to 6.5% (95% CI: 3.7% to 11.4%) using the Framingham office algorithm, with substantial differences in risk between sites. The highest risk was in South African settings (in urban Soweto: 8.9% (IQR: 5.3–15.3)). Agreement between algorithms was low to moderate (kappa from 0.03 to 0.55) and correlations ranged between 0.28 and 0.70. Depending on the algorithm used, those at high risk (defined as risk of 10-year CVD event >20%) who were under treatment for a modifiable risk factor ranged from 19.2% to 33.9%, with substantial variation by both sex and site.ConclusionThe African sites in this study are at different stages of an ongoing epidemiological transition as evidenced by both risk factor levels and estimated 10-year CVD risk. There is low correlation and disparate levels of population risk, predicted by different risk algorithms, within sites. Validating existing risk algorithms or designing context-specific 10-year CVD risk algorithms is essential for accurately defining population risk and targeting national policies and individual CVD treatment on the African continent.

Abstract Objectives This study was designed to assess the effects of mixed nut consumption on body weight and composition, and gut microbiome in obese individuals. Primary outcome was change in body weight and composition. Secondary outcomes include gut microbiome composition, inflammatory markers, and plasma lipids. Methods The reported results are from an interim analysis (n = 50) of a randomized, placebo controlled, parallel study. Total enrollment target is 154 overweight/obese subjects (BMI 27–35 kg/m2). Participants were randomly assigned to consume either 1.5oz mixed tree nuts or pretzels with equal calorie content daily for 24 weeks. The study included a 12-week weight loss phase (500 kcal per day less than total daily energy expenditure), followed by a 12-week weight maintenance phase. Body composition, fasting blood, and stool samples were collected at baseline, week 12 and 24. Body composition, and vitals were analyzed, whereas plasma lipid profile, fecal microbiome, and microbiome metabolites analysis is still pending. Results At week 12, subjects from both the pretzel (n = 15, 10 dropouts; P = 0.009) and nut group (n = 22, 3 dropouts; P = 0.038) lost significant amount of weight. The trend of weight changes did not differ between groups (P = 0.530). Subjects from both groups were able to sustain weight loss through 24 weeks (pretzel: 81.43 ± 3.85 kg at baseline vs. 79.43 ± 4.08 kg at week 24, P = 0.028; nut: 84.26 ± 3.78 kg at baseline vs. 82.38 ± 3.72 kg at week 24, P = 0.026). At week 12, fat mass in both groups was significantly decreased (pretzel: P = 0.002; nut: P = 0.012). The trend of fat changes did not differ between groups (P = 0.547). Subjects from both groups were able to sustain fat loss through 24 weeks (pretzel: 30.84 ± 1.75 kg at baseline vs. 29.25 ± 2.12 kg at week 24, P = 0.024; nut: 31.51 ± 1.56 kg vs 30.21 ± 1.81 kg at week 24, P = 0.04). Muscle mass, and blood pressure were not significantly different between both groups. Conclusions Our data suggested that tree nuts could be consumed as part of a healthy weight loss meal plan without concern of causing weight gain. Further analysis of the remaining samples is needed to confirm results. Due to higher dropouts in the pretzel group, future intention-to-treat analysis is also needed to eliminate bias.
