LOW-FAT, HIGH-FIBER DIET FAVORABLY AFFECTS SEVERAL INDEPENDENT RISK MARKERS OF ISCHEMIC-HEART-DISEASE - OBSERVATIONS ON BLOOD-LIPIDS, COAGULATION, AND FIBRINOLYSIS FROM A TRIAL OF MIDDLE-AGED DANES

We served a low-fat (28% of energy), high-fiber (3.3 g/MJ) diet according to Nordic nutrition recommendations (Rec diet), and a high-fat diet (39% of energy) corresponding to the average Danish diet (Dane diet) for periods of 2 wk in a randomized crossover study of 21 healthy middle-aged individuals. The Rec diet resulted in lower serum concentrations of low-density-lipoprotein (LDL) cholesterol (medians: 2.77 vs 3.04 mmol/L, P < 0.001) and high-density-lipoprotein (HDL) cholesterol (1.08 vs 1.24 mmol/L, P < 0.001), and higher fasting triglycerides (1.11 vs 0.86 mmol/L, P = 0.04) than did the Dane diet. Furthermore, the Rec diet lowered plasma factor VII coagulant activity (FVIIc) (88% vs 96%, P = 0.002) and raised plasma fibrinolytic activity. Our observations indicate that a low-fat, high-fiber diet may not only reduce the atherogenic but also the thrombogenic tendency of an individual compared with a diet corresponding to the average Danish diet.
