Abstract

Introduction: The elimination of meal products may lead to a modification of plasma lipid profile. However, there are no reliable data on the significance of length of this dietary modification. Therefore, the aim of the present study was to assess the influence of one-month vegan diet on plasma lipid parame ters.

Material and methods: The study comprised 12 omnivore volunteers (9 female and 3 male) aged 21 t0 35 years. In all subjects, nutritional status (body weight and BMI), nutritional intake and plasma lipid parameters (the concentration of triglycerides, total cholesterol and HDL cholesterol) before and after ‘one-month vegan diet was assessed.

Results: Statistically significant reduction of body mass / BMI and energy, cholesterol, protein and fat (Saturated and monounsaturated but not polyunsaturated fatty acids) intake was noted, whereas carbohydrate consumption increased. One-month vegan diet resulted in statistically significant increase of triglyceride concentrations and decrease of total cholesterol level (without any change with HDL fraction). The positive correlation between the changes of total plasma cholesterol and change of body mass (r=0,692, p=0,013) and BMI (r=0,664, p=0,018) was stated. The negative correlation was noted, however, between the change in HDL cholesterol concentrations and changes in energy intake (r=-0,769, p=0,003), the changes in HDL cholesterol percents and change in saturated fatty acids intake (r=-0,643, p =0,024) and change in plasma triglycerides concentrations and change in monounsaturated fatty acids (r=-0,867, p=0,0003).

Conclusion: Vegan diet results in modification of energy, macronutrients and cholesterol intake. Its short-term use leads to the reduction of body mass. The exclusion of meat from the diet results in the changes of plasma lipid profile (the decrease of total cholesterol with the increase of triglycerides).
