Dietary recommendations to decrease the risk of cardiovascular disease (CVD) have focused on reducing intake of saturated fatty acids (SFA) for more than 50 years. While the 2015-2020 Dietary Guidelines for Americans advise substituting both monounsaturated and polyunsaturated fatty acids for SFA, evidence supports other nutrient substitutions that will also reduce CVD risk. For example, replacing SFA with whole grains, but not refined carbohydrates, reduces CVD risk. Replacing SFA with protein, especially plant protein, may also reduce CVD risk. While dairy fat (milk, cheese) is associated with a slightly lower CVD risk compared to meat, dairy fat results in a significantly greater CVD risk relative to unsaturated fatty acids. As research continues, we will refine our understanding of dietary patterns associated with lower CVD risk.
50多年来,降低心血管疾病(CVD)风险的饮食建议一直侧重于减少饱和脂肪酸(SFA)的摄入量。虽然《2015 - 2020年美国膳食指南》建议用单不饱和脂肪酸和多不饱和脂肪酸替代饱和脂肪酸,但有证据支持其他营养素替代也能降低心血管疾病风险。例如,用全谷物而非精制碳水化合物替代饱和脂肪酸可降低心血管疾病风险。用蛋白质尤其是植物蛋白替代饱和脂肪酸也可能降低心血管疾病风险。虽然与肉类相比,乳制品脂肪(牛奶、奶酪)与心血管疾病风险略低相关,但相对于不饱和脂肪酸,乳制品脂肪会导致更高的心血管疾病风险。随着研究的继续,我们将加深对与较低心血管疾病风险相关的饮食模式的理解。
