AbstractIn the ongoing discussion on the health properties of palm oil, a study of the effect a diet supplemented with palm oil on blood and liver biochemical parameters, beta‐ carotene and tocochromanols content as well as antioxidant activity was undertaken. Forty Wistar rats were randomly divided into five groups, fed with a diet supple‐ mented with plant‐based frying commercial fat, palm oil, 7.5% palm oil and 2.5% con‐ centrate from palm oil and 10% of rapeseed oil, respectively. After 21 days, blood samples and livers were collected to determine beta‐carotene and tocochromanols concentrations, antioxidant activity using DPPH* radical scavenging activity and TEAC methods, insulin, glucagon, serum triacyloglycerols and cholesterol levels, glu‐ cose in blood serum and glycogen in the livers. Research has shown valuable biologi‐ cal properties of palm oil in terms of plasma glucose, total cholesterol, low‐density lipoprotein (LDL) cholesterol, and triacylglycerol concentrations which was related to the high content of beta‐carotene and tocochromanols.
