1、 "Three whites" refers to salt, sugar and fat

Too much salt can lead to high blood pressure, hardening of blood vessels, and increase the burden on kidneys. Generally speaking, the daily intake of salt should be less than 5g.

Sugar is the essential basic substance of human body, but excessive intake is easy to cause hypertension, obesity, liver function damage and so on. When cooking, you can use the method of drenching soup, thickening or dipping the boiled food into the juice to eat, and spread the sweet and salty taste on the surface of the food, which can not only satisfy the appetite, but also make the sugar and salt intake excessive.

Although fat plays an important role in our body, if we don't control it, the body's fat supply is generally greater than the demand, so we need to work hard on "saving resources" to ensure that the fat intake is appropriate, scientific and healthy. The Nutrition Society of China suggests that the dietary fat supply should not exceed 30% of the total energy, and the ratio of saturated, monounsaturated and polyunsaturated fatty acids should be 1:1:1. The energy provided by linoleic acid can reach 1% ~ 2% of the total energy, which can meet the needs of human body for essential fatty acids. The main source of fat is cooking oil and the oil contained in the food itself. The fat content of the kernel is the highest, and all kinds of meat are in the middle, while the content of rice, flour, vegetables and fruits is very little.
