The possibility to determine the botanical origin of honey samples via elemental content was examined. The employed combination of a simple, fast, and inexpensive multielement TXRF analytical approach and the evaluation of data by chemometric methods (PCA and RDA) has the potential to discriminate the botanical origins of various types of honey. From all of the measured elements only the four characteristic key elements Cl, K, Mn, and Rb could be used to best discriminate the types of honey.

The compositions of fruit juices on the Slovenian and Cypriot markets have been compared. Values of ?13C have been obtained by isotope ratio mass spectrometry (IRMS), and (D/H)I and (D/H)II ratios determined by SNIF NMR. The data showed that some juices were adulterated. Measurements of ?18O in the water and of (D/H)II in the ethanol indicated a significant difference in juices from Slovenia and Cyprus. Using PCA, very clear differentiation can be made between juices from the two countries.

The contents of the HAs are dependent on the presence of the skin and the method of grilling, with the formation HAs seen to be extensive in the absence of the skin and with direct heat transfer. The choosing of an appropriate method of thermal treatment of chicken meat to minimize the formation of HAs is one of the most important issues. Thus, the intake of HAs from grilled chicken can be reduced by not consuming the skin only in the case of infrared grilling.

The effects of meat quality, ageing time and internal temperature on the formation of mutagenic and carcinogenic HCAs in grilled pork muscles were studied. PhIP, MeIQx, DiMeIQx, Harman and Norharman were determined. Content of HCAs increases with ageing and is dependent on Ti. No marked difference due to meat quality was found in the HCAs content at Ti = 70 °C. On the average PSE samples (95 °C) contained 22 % HCAs more than normal samples. From health perspective it is the most suitable to grill pork meat (normal quality and to 3-day aged or PSE quality and nonaged) to the Ti = 70 °C.

This paper presents a reflection within the framework of the central theorem and its critics by focusing on three nutritional patterns in animals: the tendency for satiety, the tendency for fast/easy food, and the tendency for food stimulants. All of these patterns have greater beneficial effects for reproduction than for health and longevity. These and other instinctive nutritional patterns of behaviour may be important for a better understanding of human nutritional ethology.
