The Dietary Guidelines for Healthy American Adults: A Statement for Health Professionals from the Nutrition Committee, American Heart Association

Introduction: Puerto Rican adults living on the US mainland tend to have poor quality diets and adverse cardiometabolic risk. Plasma metabolomic signatures reflect dietary intakes and variability in metabolic response to diet. Hypothesis: A plasma metabolomic signature reflecting adherence to the American Heart Association (AHA) dietary guidelines will be associated with cardiometabolic risk. Methods: We used LC/MS to measure plasma metabolites (>700) among Boston Puerto Rican Health Study participants, aged 45-75 years, without (n=252) and with (n=254) type 2 diabetes (T2D). We calculated a modified version of a previously validated AHA diet score (AHA-DS), which included variety and amounts of fruits/vegetables, whole grains, fish, saturated fat, trans fat, sodium, and added sugars. We used elastic net regression to identify a metabolomic signature that associated with higher adherence to the AHA-DS among those without T2D (training set) and replicated the associations among those with T2D (testing set). A metabolomic score was calculated as the weighted sum of the diet associated metabolites. We used general linear models to determine the cross-sectional associations between the AHA-DS, metabolomic score, and cardiometabolic risk factors. Results: A diet-associated metabolomic signature with 58 metabolites, primarily lipids and amino acids, was identified. This metabolomic score correlated moderately with the AHA-DS among those with and without T2D (r=0.42-0.46, P <5.7x10 -12 ). In all participants (n=506), the metabolomic score, but not the AHA-DS, was significantly associated with higher HDL-C and LDL-C concentrations, and lower waist circumference ( P <0.004; Table 1). No associations were observed for triglyceride concentrations, glycemia measures, or blood pressure. Conclusions: In individuals of Puerto Rican descent, we identified a metabolomic signature that reflected adherence and metabolic response to the AHA dietary guidelines and that associated with cardiometabolic risk factors.

Abstract Objectives Because the relationship between diet and hypertensive disorders of pregnancy (HDPs), including preeclampsia, remains unclear we aim to evaluate the association between pre-pregnancy adherence to the American Heart Association (AHA) diet recommendations and the Dietary Approaches to Stop Hypertension (DASH) dietary pattern with risk of developing preeclampsia (PE). Methods Our prospective cohort study included 20,024 pregnancies from 13,645 women enrolled in the Nurses’ Health Study II (NHS2) (1991 to 2007). Pre-pregnancy diet was measured in 1991 by a semi-quantitative food frequency questionnaire and updated every four years. Pregnancy outcomes were self-reported every 2 years during follow-up. We derived the DASH scores based on the intake of 8 food groups (fruits and fruit juices, vegetables, whole-grain, red and processed meats, nuts and legumes, sugar sweetened beverages, and sodium). The AHA score was derived from 5 food groups (fruits and vegetables, whole grain, fish, SSBs and sodium) consistent with AHA dietary guidelines to reduce hypertension in the general population. We estimated the RR and 95% CIs of PE by log-Poisson regression employing generalized estimating equations and adjusting for total energy intake, age at pregnancy, BMI, physical activity, parity, smoking status, infertility, marital status, multivitamin use, and gestational diabetes. Results HDPs were reported in 1,089 (5.4%) pregnancies, of which 505 (2.5%) were PE. The DASH score (max points = 40) ranged from 16 to 32 points and the AHA score (max score = 50) ranged from 18 to 41 points in our population. Compared to women in the lowest quintile of adherence to the AHA, the RR (95%CI) of PE in quintiles 2, 3, 4, and 5 were 0.88 (0.68, 1.14), 0.87 (0.66, 1.15), 0.83 (0.64, 1.09), and 0.79 (0.60, 1.06), respectively (p-trend = 0.09). Similarly, the RR (95%CI) of PE among women in increasing quintiles of adherence to the DASH score was 0.88 (0.68, 1.13), 0.72 (0.55, 0.94), 0.80 (0.61, 1.05), and 0.62 (0.45, 0.84) compared to women in the lowest quintile (p-trend = 0.002). Conclusions Stronger pre-pregnancy adherence to the DASH dietary pattern was inversely associated to developing PE among participants of the NHS2.
