近代医学科学研究发现:肥肉中的胆固醇会增高心血管病的发生机会。由于有这一发现,不少人说起吃肥肉,大都“谈虎色变”。人们不敢吃肥肉,主要是怕摄入较多的脂肪,引起身体发胖,血脂升高,影响身体健康。然而,肥肉中含有的脂肪也是人体必不可少的营养素之一。它不仅能维持体温,固定组织,保护内脏,还能调节生理功能和促进脂溶性维生素 A、K、E、D 及胡萝卜素等的吸收、利用。如长期少食脂肪(每天少于50克),就可能会出现脂溶性维生素缺乏,引起视力、凝血、骨骼的正常功能障碍及皮肤病等。肥肉中含有0.3%～0.5%的花生四烯酚,有助于降低血脂,而它在植物油中一般也存在,也就是说,适量进食肥肉,并不会引起血脂增高。
Modern medical science research found that: cholesterol in fat will increase the chance of cardiovascular disease. As a result of this discovery, many people talk about eating fat, mostly “talkative”. People are afraid to eat fat, mainly because they are afraid of ingesting more fat, causing their body to gain weight, raising blood lipids and affecting their health. However, fat contained in fat is also one of the essential nutrients in the body. It can not only maintain body temperature, fixed tissue, protect the internal organs, but also regulate physiological functions and promote the absorption and utilization of fat-soluble vitamins A, K, E, D and carotene. Such as long-term Eat less fat (less than 50 grams per day), there may be fat-soluble vitamin deficiency, causing vision, blood clotting, normal dysfunction and skin disorders. Fat content of 0.3% to 0.5% of arachidonic acid, helps to reduce blood fat, and it is also generally present in vegetable oil, that is, moderate consumption of fat, does not cause elevated blood lipids.
