No more than 25 grams and a half gallons of oil per person per day.
Edible oil can provide heat for human body, essential fatty acids, fat-soluble vitamins, edible essence and production function that human body can't synthesize ... The role of edible oil can't be underestimated. But the more edible oil, the better.
According to the recommendation of the Nutrition Society of China, a person should not consume more than 25g (half Liang) of edible oil every day, which includes not only cooking oil at home, but also the oil consumed by eating pork and other foods.
Excessive oil intake will not only lead to obesity, but also lead to excessive fatty acids in the blood. When fatty acids are surplus, they will be mainly stored in the form of triglycerides, which will lead to the increase of blood lipids and cause cardiovascular and cerebrovascular diseases.
