Chicken eggs have always been one of the most useful products. But the people of the 21st century began to think about cholesterol and other things that are much less known before. And eggs have announced a product that can not be consumed daily. Let’s see, is it really so harmful eggs, or they are still more useful? To answer this question it is possible, after weighing all the pros and cons.
The main argument against eggs is cholesterol, which is found in egg yolk. Because of it, lot of people take them of from a healthy lifestyle. At the same time, other scientists argue that use 1 egg per day is normal that in such quantities cholesterol is not able to cause harm to our body.
Indeed, the yolk contains vitamin A, vitamin D, and vitamin E, moreover, it is rich in polyunsaturated fatty acids (omega-3 fatty acids), such as linoleic acid. Remember that in the white of the egg there are nothing from these things.
