[Errors in practising a so-called "reasonable" regimen (author's transl)].

The significant decrease of the serum concentrations of total cholesterol, triglycerides, phosphatides, beta-cholesterol, and beta-lipoproteins, which usually is observed after conversion from normal eating habits to a "reasonable" diet, is prevented by supplementary and unverifiable consumption of confectionery and/or by alcohol abuse in irregular intervals. The so-called "reasonable" regimen is a high-fat and protein-rich diet food containing more than 50 per cent of multiple-unsaturated fatty acid in the fat supply. The fact that the average serum concentrations of the divers lipid fractions within the entire group of the 30 patients examined (patients who - admittedly - were practising a luxury form of consumption) showed merely insignificant fluctuations, is in no way a justification for the conclusion that a "reasonable" diet will at any time ostensively represent a protection against the effect of luxury consumption on the serum lipids.
