生活在赤道附近环礁上的两群波利尼西亚人提供了一个研究饱和脂肪和膳食胆固醇在决定血清胆固醇水平方面相对影响的机会。普卡普卡岛和托克劳群岛的环礁居民的日常饮食中饱和脂肪含量高，但膳食胆固醇和蔗糖含量低。椰子是这两个群体的主要能量来源。托克劳人从椰子中获取的能量百分比比普卡普卡人高得多，分别为63%和34%，所以他们摄入的饱和脂肪更高。托克劳人的血清胆固醇水平比普卡普卡人高35 - 40毫克。血清胆固醇水平的这些主要差异被认为是由于托克劳人摄入的饱和脂肪更高。对各种食物样本和人体脂肪活检的分析显示，月桂酸（12:0）和肉豆蔻酸（14:0）含量较高。血管疾病在这两个人群中都不常见，没有证据表明高饱和脂肪摄入对这些人群有有害影响。
Two populations of Polynesians living on atolls near the equator provide an opportunity to investigate the relative effects of saturated fat and dietary cholesterol in determining serum cholesterol levels. The habitual diets of the atoll dwellers from both Pukapuka and Tokelau are high in saturated fat but low in dietary cholesterol and sucrose. Coconut is the chief source of energy for both groups. Tokelauans obtain a much higher percentage of energy from coconut than the Pukapukans, 63% compared with 34%, so their intake of saturated fat is higher. The serum cholesterol levels are 35-40 mg higher in Tokelauans than in Pukapukans. These major differences in serum cholesterol levels are considered to be due to the higher saturated fat intake of the Tokelauans. Analysis of a variety of food samples and human fat biopsies show a high lauric (12:0) and myristic (14:0) content. Vascular disease is uncommon in both populations, and there is no evidence of the high saturated fat intake having a harmful effect in these populations.
