An average reduction in serum cholesterol approximating 10 per cent was achieved in a short-term, family-centered study in which intakes of cholesterol and saturated fats were decreased and sunflower oil and margarine were added as the major sources of polyunsaturated fats. Dietary Achievement Scores demonstrated shifts in food consumption between baseline and diet periods. Changes were evident in all fat-containing food groups; meat was the least altered. A high degree of cooperation was evident in participating families, implying the possibilities for complete family cooperation in preventive or therapeutic dietary programs. Approximately three months after the end of the test period, cholesterol levels had returned to pre-diet levels, indicating the need for continuation of the changed regimen if cholesterol-lowering is to be maintained.
在一项短期的、以家庭为中心的研究中，血清胆固醇平均降低了约10%。在该研究中，胆固醇和饱和脂肪的摄入量减少，向日葵油和人造黄油被添加为多不饱和脂肪的主要来源。饮食成就得分显示了基线期和饮食期之间食物消费的变化。所有含脂肪食物组都有明显变化；肉类变化最小。参与研究的家庭表现出高度的合作，这意味着在预防性或治疗性饮食计划中完全有可能实现家庭合作。在试验期结束大约三个月后，胆固醇水平已恢复到饮食前水平，这表明如果要维持降低胆固醇的效果，就需要继续改变饮食方案。
