The paper deals with some topics of important aspects of food safety and application of principles of food physics in the sector of agriculture, food technology, biotechnology, including questions of well balanced nutrition, as well. One of the most important and widely applied field of biotechnology is the food technology. Food production and processing of quality food and safe food are today of primary importance. Food production is based on the principles of GAP, GMP and GHP. Recently the industrial food processing is focused dominantly on the quality, and one of the basic requirements of the quality is the safety.

There are various methods and techniques to produce safe food. The modern food technologies and quality measurements (quality control, quality assurance) involve the application of different physical methods - e.g. high pressure, pulsing electrical field, nondestructive techniques (e.g. NMR, NIR-NIT, PAS, INAA) for chemical composition determination, radiation techniques, nanofiltration and reverse osmosis (RO) - as well. Using e.g. ionizing radiation (nuclear methods) and non-ionizing radiation technologies it is possible to fulfil a lot of important expectations: decrease of microbial contamination, improve of sensory properties, increase of storability, etc.

The paper deals with questions of up-to-date, with sport motion combined diet, helping in keeping the health, as well. In the last decades a lot of information were distributed concerning several viewpoints of bodyweight reduction and optimation of bodymaa. How should we know that it is useful and not unhealthy? A suitable Nutrition software (AOPNEI, Analysing and Optimation Program for Nourishment and Energy Intake) - developed at the Department of Food Chemistry and Nutrition of the Faculty of Food Science, Corvinus University - can help.
