Nutritional status is a well-recognized prognostic indicator in chronic obstructive pulmonary disease (COPD); however, very little is known about the relationship between lung function and saturated fat intake. We used data from the cross-sectional National Health and Nutrition Examination Surveys (NHANES) to assess the relationship between saturated fatty acid (SFA) intake and lung function in the general US adult population. Adults in NHANES (2007–2012) with pre-bronchodilator spirometry measurements and dietary SFA intake were included. Primary outcomes were lung function including forced expiratory volume in one second (FEV1), FEV1, forced vital capacity (FVC), FEV1/FVC ratio, percent predicted FEV1 and percent predicted FVC. Multivariable regression models in the general population as well as those with spirometry-defined airflow obstruction were used to assess the relationship between lung function measurements and dietary SFA intake after adjustment for confounders. 11,180 eligible participants were included in this study. Univariate analysis revealed a statistically significant positive association between total SFA intake and lung function outcomes; however, these relationships were attenuated after adjustment for covariates. A secondary analysis of individuals with spirometry-defined airflow obstruction (FEV1/FVC < 0.7) revealed that a lower intake of SFA was associated with reduced FEV1 (β = −126.4, p = 0.04 for quartile 1 vs. quartile 4), FVC (β = −165.8. p = 0.01 for quartile 1 vs. quartile 4), and percent predicted FVC (β = −3.3. p = 0.04 for quartile 1 vs. quartile 4), after adjustment for relevant confounders. No associations were observed for the FEV1/FVC ratio and percent predicted FEV1. It is possible that characteristics such as food source and fatty acid chain length may influence associations between saturated fatty acid intake and health outcomes.

AbstractObjectiveThe present study aimed to assess the relationship between hs-CRP concentrations and total and saturated fat intake in adolescents after a year of follow-up.MethodsA longitudinal study carried out in the years 2014 and 2015 evaluated 408 adolescents from the municipal and state public schools of João Pessoa, Paraíba, between 10 and 14 years of age, who participated in the Longitudinal Study on Sedentary Behavior, Physical Activity, Eating Habits and Adolescent Health (LONCAAFS). Data were obtained on sociodemographic data, anthropometric nutritional status, physical activity and hs-CRP concentration. The consumption of total and saturated fats was evaluated from the 24 hour recall.ResultsThe associations between concentrations of hs-CRP and total and saturated fat intake were performed by linear regression considering panel data, individual fixed effect, balanced bank, stratified by sex and BMI. The mean values of the hs-CRP variable were significantly different between the analyzed years (p = 0.024). The percentage of total and saturated fat consumption is within the recommended level in both years, with no significant difference (p> 0.05). No statistically significant associations were found between hs-CRP and total fat consumption (β = −0.19p = 0.582) and saturated fat (β = 0.20, p = 0.282).ConclusionThe study did not present significant evidence on the relationship between the concentrations of hs-CRP and the consumption of total and saturated fats, as one year of follow-up may not have promoted evident changes in the levels of hs-CRP in adolescents.

Background: Epidemiological studies showed that dietary fat intake is associated with Alzheimer’s disease (AD) and dementia risk, however, the association remain inconsistent. This metaanalysis aimed to systematically examine the association of dietary fat intake with AD and dementia risk. Methods: We have systematically searched PubMed, Embase and the Cochrane Library up to May 1st 2017. Prospective cohort studies were included if they reported on the association of dietary fat intake with AD and dementia risk. Multivariate-adjusted relative risks (RRs) for the highest versus lowest category were pooled by using a random-effects model. Results: A total of 8630 participants and 633 cases from four independent prospective cohort studies were included in the present meta-analysis. A higher dietary saturated fat intake was significantly associated with an increased risk of 39% and 105% for AD (RR: 1.39; 95% CI: 1.00, 1.94) and dementia (RR: 2.05; 95% CI: 1.06, 3.98), respectively. Dose-response analysis indicated a 4 g/day increment of saturated fat intake was related to 15% higher risk of AD (RR: 1.15; 95% CI: 1.01, 1.31). However, there was no significant association found between dietary intake of total, monounsaturated, polyunsaturated fat and AD or dementia risk. Conclusions: This meta-analysis provides significant evidence of positive association between higher saturated fat intake and AD and dementia risk.

ABSTRACTBackgroundFor low-carbohydrate diets, a public health approach has focused on the replacement of carbohydrates with unsaturated fats. However, little research exists on the impacts of saturated fat intake on the lipid profile in the context of whole-food-based low-carbohydrate weight-loss diets.ObjectivesThe primary aim of this secondary analysis of the DIETFITS weight loss trial was to evaluate the associations between changes in percentage of dietary saturated fatty acid intake (%SFA) and changes in low-density lipoproteins, high-density lipoproteins, and triglyceride concentrations for those following a healthy low-carbohydrate (HLC) diet. The secondary aim was to examine these associations specifically for HLC dieters who had the highest 12-month increases in %SFA.MethodsIn the DIETFITS trial, 609 generally healthy adults, aged 18–50 years, with body mass indices of 28–40 kg/m2 were randomly assigned to a healthy low-fat (HLF) or HLC diet for 12 months. In this analysis, linear regression, both without and with adjustment for potential confounders, was used to measure the association between 12-month change in %SFA and blood lipids in 208 HLC participants with complete diet and blood lipid data.ResultsParticipants consumed an average of 12–18% of calories from SFA. An increase of %SFA, without significant changes in absolute saturated fat intake, over 12 months was associated with a statistically significant decrease in triglycerides in the context of a weight-loss study in which participants simultaneously decreased carbohydrate intake. The association between increase in %SFA and decrease in triglycerides was no longer significant when adjusting for 12-month change in carbohydrate intake, suggesting carbohydrate intake may be a mediator of this relationship.ConclusionsThose on a low-carbohydrate weight-loss diet who increase their percentage intake of dietary saturated fat may improve their overall lipid profile provided they focus on a high-quality diet and lower their intakes of both calories and refined carbohydrates. This trial was registered at clinicaltrials.gov as NCT01826591.
