Carbohydrate and protein replacers of fat are frequently used by food manufacturers in response to the increased risk of diseases, which are connected with oversupply of energy and lipids in the diet. Low-calorie replacers such as inulin can limit hunger and normalize blood cholesterol levels. Increases in the nutritional value of food products can be achieved by partially replacing fat by soy protein isolates. Amino acids and deficient minerals like calcium and iron can be provided by food containing protein-based fat substitutes. Some fat substitutes, like maltodextrin, can slightly reduce the bioavailability of the fat-soluble vitamins. As a result, food products containing maltodextrin should be fortified with the affected substances to reduce the risk of malnutrition. The long-term effects of carbohydrate and protein replacers on the human body have not been sufficiently explained, and so fat replacers should be limited in the daily diet.

Anti-proliferative activity was investigated of C18:2 9cis,11trans (conjugated linoleic acid – CLA) isomer isolated from sheep milk fat. The research was conducted on sheep milk fatty acids in natural composition (FA-1) containing 2.0% of the C18:2 9cis,11trans CLA isomer and preparation enriched with CLA, containing up to 9.2% of the CLA isomer (FA-2). The process of enrichment of FA-1 was carried out in two steps. Step I was to remove mid-chain-length saturated fatty acids, primarily C16,by forming adducts with urea (to obtain FA-U), while in step II the short-chain acids were removed by way of supercritical extraction with CO2. The final preparation obtained (FA-2) contained 9.2% of the C18:2 9cis,11trans isomer. A natural sheep milk fatty acid composition (FA-1), the CLA-enriched product (FA-2) and a commercial CLA preparation (CP) were tested for anti-proliferative activity against the cells of human cervical carcinoma (KB), and leukaemia (HL-60). The ID50 dose (resulting in a 50% inhibition of cell proliferation) of FA-2 was found lower than that of the CP preparation. The SRB test showed.
