Nutritional value of lard
1, providing energy
Lard is rich in energy, which mainly provides energy for human body. 1 g lard (refined) can provide 8.79 kcal energy for human body. If you eat too much lard, the fat stored in your body will increase and people will get fat. If the energy of food eaten for a long time is insufficient, the body fat will gradually decrease, making people thin.
Step 2 provide essential fatty acids
In human body, fat can be synthesized by excessive protein and carbohydrate, that is, excessive intake of protein and carbohydrate (sugar) can be converted into fat in human body. Fatty acids necessary for human body, such as linoleic acid, cannot be synthesized by human body and need to be provided through the fat in the food eaten. If the human body lacks linoleic acid, it will cause growth stagnation, weight loss and scaly skin. Lard contains linoleic acid, so lard can provide essential fatty acids for human body.
Step 3 protect your body
Lard is a kind of fat, and fat is a structural component of human body, which can keep warm, buffer, lubricate and protect various organs in the body from damage. For example, people with more subcutaneous fat have stronger frost resistance. If they fall, they can protect their internal organs from damage due to the buffering and lubricating effects of subcutaneous fat. So lard can protect the body.
4, increase the flavor of food and help absorption.
The dishes fried with lard are more fragrant and smoother than those fried with other oils, so lard can increase flavor and improve the taste of food. Lard is easy to dissolve with fat-soluble vitamins (such as vitamin A, vitamin D, vitamin E and vitamin K), so lard helps to absorb fat-soluble vitamins.
5. Digestion and absorption of lard
Lard is easily digested and absorbed by human body. After absorption, it can be quickly used by the human body, and it is not easy to feel full. Usually lard can be completely digested in human body in 6~8 hours. After lard enters human body, it absorbs 24~4 1% in 2 hours, 53~7 1% in 4 hours and 68~86% in 6 hours.
