The relationship between nutritional, as well as non-nutritional
food components and human health is at the core of current
research on disease prevention. Such studies concentrate typically
on the search for specific edible compounds, especially bioactive
phytochemicals exhibiting defined biological effects, with the aim
of introducing them into human diet in a form of supplements or
fortified foods. However, the possible impact of small yet sustainable
changes in food production technology, e.g. salt content
reduction, has been recognized as a means ensuring health benefits
not less important than those offered by so called novel or functional
foods. The ubiquitous ingredients that could be replaced with
healthier alternatives are food additives that are present in all kinds
of alimentary products. One of such an omnipresent additive is
