This review provides a reappraisal of the potential effects of dairy foods, including dairy fats, on cardiovascular disease (CVD)/coronary heart disease (CHD) risk. Commodities and foods containing saturated fats are of particular focus as current public dietary recommendations are directed toward reducing the intake of saturated fats as a means to improve the overall health of the population. A conference of scientists from different perspectives of dietary fat and health was convened in order to consider the scientific basis for these recommendations.
This review and summary of the conference focus on four key areas related to the biology of dairy foods and fats and their potential impact on human health: (a) the effect of dairy foods on CVD in prospective cohort studies; (b) the impact of dairy fat on plasma lipid risk factors for CVD; (c) the effects of dairy fat on non-lipid risk factors for CVD; and (d) the role of dairy products as essential contributors of micronutrients in reference food patterns for the elderly.
Despite the contribution of dairy products to the saturated fatty acid composition of the diet, and given the diversity of dairy foods of widely differing composition, there is no clear evidence that dairy food consumption is consistently associated with a higher risk of CVD. Thus, recommendations to reduce dairy food consumption irrespective of the nature of the dairy product should be made with caution.
本综述重新评估了乳制品(包括乳脂肪)对心血管疾病(CVD)/冠心病(CHD)风险的潜在影响。含饱和脂肪的商品和食物受到特别关注,因为当前的公共饮食建议旨在减少饱和脂肪的摄入量,以此作为改善人群整体健康的一种手段。为此召开了一次由来自饮食脂肪与健康不同领域的科学家参加的会议,以探讨这些建议的科学依据。
本综述及会议总结聚焦于与乳制品和脂肪生物学及其对人类健康潜在影响相关的四个关键领域:(a)前瞻性队列研究中乳制品对心血管疾病的影响;(b)乳脂肪对心血管疾病血浆脂质风险因素的影响;(c)乳脂肪对心血管疾病非脂质风险因素的影响;(d)乳制品作为老年人参考食物模式中微量营养素重要来源的作用。
尽管乳制品会增加饮食中饱和脂肪酸的含量,且乳制品成分差异很大,但尚无明确证据表明食用乳制品会一直增加心血管疾病风险。因此,不论乳制品的性质如何就建议减少其消费量时应谨慎行事。
