Abstract：
Some consider potatoes to be unhealthy vegetables that may contribute to adverse cardiometabolic health outcomes. We evaluated the association between potato consumption (including fried and non-fried types) and three key cardiometabolic outcomes among middle-aged and older adults in the Framingham Offspring Study. We included 2523 subjects ≥30 years of age with available dietary data from 3-d food records. Cox-proportional hazards models were used to estimate hazard ratios (HRs) and 95 % confidence intervals (CIs) for hypertension, type 2 diabetes or impaired fasting glucose (T2DM/IFG), and elevated triglycerides, adjusting for anthropometric, demographic and lifestyle factors. In the present study, 36 % of potatoes consumed were baked, 28 % fried, 14 % mashed, 9 % boiled and the rest cooked in other ways. Overall, higher total potato intake (≥4 v. <1 cup-equivalents/week) was not associated with risks of T2DM/IFG (HR 0⋅97, 95 % CI 0⋅81, 1⋅15), hypertension (HR 0⋅95; 95 % CI 0⋅80, 1⋅12) or elevated triglycerides (HR 0⋅99, 95 % CI 0⋅86, 1⋅13). Stratified analyses were used to evaluate effect modification by physical activity levels and red meat consumption, and in those analyses, there were no adverse effects of potato intake. However, when combined with higher levels of physical activity, greater consumption of fried potatoes was associated with a 24 % lower risk (95 % CI 0⋅60, 0⋅96) of T2DM/IFG, and in combination with lower red meat consumption, higher fried potato intake was associated with a 26 % lower risk (95 % CI 0⋅56, 0⋅99) of elevated triglycerides. In this prospective cohort, there was no adverse association between fried or non-fried potato consumption and risks of T2DM/IFG, hypertension or elevated triglycerides.
摘要：
有些人认为土豆是不健康的蔬菜，可能会导致不良的心脏代谢健康结果。在Framingham后代研究中，我们评估了中年和老年人的马铃薯消费（包括油炸和非油炸类型）与三个关键心脏代谢结果之间的关联。我们纳入了2523名年龄≥30岁的受试者，这些受试者的饮食数据来自3-d食物记录。Cox比例风险模型用于估计高血压的风险比（HR）和95％置信区间（CI）。2型糖尿病或空腹血糖受损（T2DM/IFG），和高甘油三酯，调整人体测量学，人口和生活方式因素。在本研究中,食用的36％的土豆是烤的，28%油炸，14%捣碎，9%煮沸，其余以其他方式煮熟。总的来说,较高的马铃薯总摄入量（≥4v。<1杯当量/周）与T2DM/IFG的风险无关（HR0·97，95％CI0·81，1·15），高血压（HR0·95；95％CI0·80，1·12）或甘油三酸酯升高（HR0·99，95％CI0·86，1·13）。分层分析用于评估身体活动水平和红肉消费的效果变化，在这些分析中，马铃薯摄入没有不良影响。然而,当与更高水平的体力活动相结合时，油炸土豆的消费量增加与T2DM/IFG的风险降低24%(95%CI0·60，0·96)相关，再加上红肉消费减少，油炸马铃薯摄入量增加与甘油三酯升高的风险降低26%(95%CI0·56,0·99)相关.在这个前瞻性队列中，油炸或非油炸马铃薯消费与T2DM/IFG风险之间没有不良关联，高血压或甘油三酯升高。
