Effect of compositional modification of coffee on certain indices of lipid metabolism in healthy volunteers and patients with hyperlipoproteinemia

: An effect of a 14-day drinking of coffee on some blood serum indices of lipid metabolism was investigated in 20 healthy volunteers and 20 patients with hyper lipoproteinemia (type IIb). The study was carried out in two subgroups: healthy volunteers or patients with hyperlipoproteinemia assigned to the first subgroup drank ordinary coffee and patients assigned to the second subgroup drank coffee deprived of irritant substances (4 glasses daily). It was found that ordinary coffee significantly increased total serum cholesterol and decreased serum HDL-cholesterol in healthy volunteers. Such effects were not seen in subgroup drinking coffee deprived of irritant substances. More significant increase in serum total cholesterol and decrease in serum HDL-cholesterol were found in patients with hyperlipoproteinemia. Drinking of modified coffee does not cause any significant changes in serum lipid metabolism. The authors concluded that drinking of the ordinary coffee should be restricted in patients with hyperlipoproteinemia and use of coffee deprived of irritant substances might be recommended to patients with this disease.
