The role of animal nutrition in improving the nutritive value of animal-derived foods in relation to chronic disease

摘要: Foods derived from animals are an important source of nutrients in the diet; for example, milk and meat together provide about 60 55% dietary intake Ca protein respectively UK. However, certain aspects some animal-derived foods, particularly their fat saturated fatty acid (SFA) contents, have led to concerns that these foods substantially contribute risk CVD, metabolic syndrome other chronic diseases. In most parts Europe dairy products greatest single SFA. The composition various is, however, not constant can, many cases, be enhanced by animal nutrition. particular, with reduced concentrations C12-16 SFA increased concentration 18:1 MUFA is achievable, although enrichment very-long-chain n-3 PUFA much less efficient. there now evidence (notably products) contain compounds may actively promote long-term health, research urgently required fully characterise benefits associated consumption understand how levels natural can enhanced. It also vital beneficial effects inadvertently destroyed process reducing future role nutrition creating closer optimum human health likely become increasingly important, but production such on a scale will affect national diets require political financial incentives great changes industry.
