The objective of the study was to investigate whether expert advice from a clinical nutritionist improves the diet of patients who have previously been instructed by health professionals to follow a lipid-lowering diet. We investigated dietary composition before and after dietary intervention by a clinical nutritionist in 46 individuals, aged 33 to 65 years, with primary hypercholesterolemia. After intervention, there was a 25% reduction in the intake of saturated fat and of cholesterol (p < 0.0001) and an 65% elevation of the P/S-ratio (p < 0.05). Percentage of energy from fat remained unchanged. The diet of patients who are already following a lipid-lowering diet can be improved by expert advice from a clinical nutritionist, and they easily adjust to new habits.
该研究的目的是调查临床营养学家提供的专业建议是否能改善那些先前已接受健康专业人员指导遵循降脂饮食的患者的饮食情况。我们调查了46名年龄在33至65岁之间、患有原发性高胆固醇血症的个体在接受临床营养学家饮食干预前后的饮食构成。干预后，饱和脂肪和胆固醇的摄入量减少了25%（p<0.0001），P/S比值升高了65%（p<0.05）。脂肪提供的能量百分比保持不变。临床营养学家的专业建议可以改善已经在遵循降脂饮食的患者的饮食，并且他们很容易适应新的饮食习惯。
