据美国心脏协会(AHA)发表声明称,超低脂肪食物虽能降低患心血管疾病危险性,但尚未有充分数据表明其能降低总胆固醇,特别是血中低密度脂蛋白(LDL)胆固醇水平。而且,声明认为,超低脂肪食物至少在短期内不会使LDL水平更进一步下降,而趋于增高三甘酯和减少高密度脂蛋白(HDL)胆固醇水平。因此,该协会将不会对公众劝告:超低脂肪食物会减少体重或降低心血管疾病死亡危险性。 食物中脂肪提供总热量低于1.5％可定义为超低脂食物,美国心脏协会曾提出每日膳食中脂肪热量不应超过30％,但饱和脂热量也不应低于10％。许多研究表明对于能减少患心血管病危险性其他因子还有:如增加水果和蔬菜摄取,加强身体活动度和减少体重等。而且,超低脂食物能否充分供应维生
According to a statement from the American Heart Association (AHA), although ultra-low fat foods reduce the risk of cardiovascular disease, there is insufficient data to show that they can lower total cholesterol, especially low-density lipoprotein (LDL) cholesterol . Moreover, the statement states that at least in the short term, ultra-low fat foods will not further reduce LDL levels, but tend to increase triglycerides and reduce HDL cholesterol levels. As a result, the association will not advise the public that ultra-low fat foods will reduce weight or reduce the risk of death from cardiovascular disease. Fat in foods providing less than 1.5% of total calories can be defined as ultra-low fat foods. The American Heart Association has proposed that the daily caloric content of fat should not exceed 30%, but the saturated fat should not be less than 10%. Many studies have shown that other factors that reduce the risk of cardiovascular disease include increased intake of fruits and vegetables, increased physical activity and weight loss. And, can ultra-low-fat foods be adequately supplied for subsistence
