The decreasing of content of animal, palmitic milk fat (butter) by means of its substitution with vegetable, oleic, palmy oil in food of adults optimal by its quantity is physically chemically and biologically substantiated. In oleic palmy oil higher content of oleic mono unsaturated fatty acid and oleic triglycerides than in creamy fat is established. The biologic availability of palmitic unsaturated palmitic acid in the form of free fatty acid is decreased at its absorption by enterocytes of small intestines is detected. There are no transforms of mono unsaturated acids in palmy oil in contrast with hydrogenated margarines. In palmy, oleic oil there is not enough of short-chained fatty acids (C4-C6) and it has no taste quality and it has low level of unsaturated fatty acids and factually it is lacking of ω-6 polyunsaturated fatty acids. However, it is compensated in case of availability offish and sea products in food. If adults, especially older ones, will refuse to consume creamy fat and decrease intake of products with high content of palmitic unsaturated fatty acid and palmitic triglycerides (beef, sour cream, fatty cheeses) it'll positively impact their health. The refusal from these products is a real step in prevention of metabolic pandemic (atherosclerosis and atheromatosis, metabolic syndrome, resistance to insulin, obesity). There are still large number of people who at optimal amount of food retain in vivo increased amount of exogenous, endogenously synthesized from glucose palmitic unsaturated fatty acid in the form of unesterified fatty acids (syndrome of resistance to insulin) and increased content of palmitic triglycerides.
通过用植物性油酸棕榈油替代动物性棕榈乳脂肪(黄油),使其在成年人食物中的含量达到最佳水平,这在物理化学和生物学上是有依据的。研究发现,油酸棕榈油中油酸单不饱和脂肪酸和油酸甘油三酯的含量高于乳脂肪。检测到游离脂肪酸形式的棕榈不饱和脂肪酸在被小肠肠细胞吸收时,其生物利用率降低。与氢化人造黄油不同,棕榈油中的单不饱和酸不会发生转化。棕榈油酸油中短链脂肪酸(C4 - C6)含量不足,没有风味品质,不饱和脂肪酸含量低,实际上缺乏ω - 6多不饱和脂肪酸。然而,如果食物中有鱼和海产品,这种情况可以得到弥补。如果成年人,尤其是老年人,拒绝食用乳脂肪并减少高含量棕榈不饱和脂肪酸和棕榈甘油三酯产品(牛肉、酸奶油、高脂奶酪)的摄入量,将对他们的健康产生积极影响。拒绝食用这些产品是预防代谢性大流行(动脉粥样硬化和动脉粥样瘤、代谢综合征、胰岛素抵抗、肥胖)的切实举措。仍有大量人在食物摄入量最佳的情况下,体内未酯化脂肪酸形式的外源性、由葡萄糖内源性合成的棕榈不饱和脂肪酸含量增加(胰岛素抵抗综合征),且棕榈甘油三酯含量升高。
