During the treatment of coronary heart disease with a vegetable-fruit diet, we have observed the positive effect of the treatment on PCT patients. Therefore, we have now examined the short-term results of the diet on the selected PCT activity parameters. The study was approved by our Review Board.


A group of 13 male PCT patients (mean age 52 years) was evaluated. We assessed the body mass index (BMI), serum iron level, activity of transaminases (ALT, AST), severity of skin symptoms, and urinary prophyrins excretions, before and after a three-week period of vegetable-fruit diet. The diet was of natural vegetable/fruit products, and its daily caloric content was ca. 500 kcal/day.


The mean BMI before and after the diet period were 26.8 +/- 4.7 vs. 25.8 +/- 4.3 (p = 0.001), the serum activities of ALT 122.0 +/- 60.7 U/l vs. 75.6 +/- 31.8 U/l, and of AST 91.8 +/- 56.0 U/l vs. 55.2 +/- 14.2 U/l (p = 0.001), respectively. The mean serum iron levels were 188.6 +/- 75.7 mg/dl vs. 140.2 +/- 56.4 mg/dl, serum ferritin concentrations 574 +/- 351 vs. 499 +/- 340 ng/ml (p = 0.04), respectively. Severity of skin lesions and urinary coproporphyrins excretion were significantly diminished during the diet; urinary uroporphyrins excretion was also lowered, but not to a statistically significant level.


In our group of PCT patients, we noticed the beneficial effect of the vegetable-fruit diet on selected disease parameters. The diet may be useful in the treatment of PCT and diseases associated with PCT.
