Hamburg is a collection of high calories and low nutritional density. Although the combination basically contains seven kinds of nutrients, except for fat, carbohydrates and a small amount of protein, there are few other vitamins, minerals and dietary fiber, which can't meet the needs of a meal. At the same time, high calorie is easy to cause fat accumulation in the body, which does more harm than good to the body besides satisfying the taste. Eating regularly may affect the normal development of the body. Hamburger blanks contain a lot of fat. Moreover, the "hydrogenated vegetable oil" widely used at present contains more "trans fatty acids", which is harmful.
