Given the fact that the nutritional value, safety and health status of food produced by conventional agriculture vary around the world, the system of organic farming is emerging as a system that achieves a sustainable production of healthy and safe food, free of pesticide residues. This paper presents evidence that organic foods compared to conventional contain significantly less nitrates, a higher level of dry substance and minerals (especially Fe, Mg and P), vitamin C, essential amino acids and total sugars, then the phenolic compounds, while foods of animal origin contain more unsaturated fatty acids. As for the level of protein, it is generally lower in organic foods. The current scientific data indicate that there is an insufficient number of studies on vitamin levels, in particular β-carotene and vitamin B group. Organically produced fruits and vegetables (in particular apple, cherry, currants, sugar beet, beetroot, carrot, spinach, kale and potatoes) contain higher levels of sucrose and total all sugars. When it comes to animal products, the current available data are insufficiently documented due to different farming systems on farms. However, studies show that chicken eggs and cow’s milk do not show significant differences in protein content compared to conventionally produced, organic cow’s milk products contain less lipids, while organic chicken meat has a much higher level of iron. However, strict rules laid down by the system of organic production provides food production that meets high quality standards.
