What is the intake of edible oil?

The Dietary Guide for China Residents recommends that each person's daily intake of edible oil is 25-30g, including vegetable oil and animal oil. Fat is an essential nutrient for human body, but eating more oil means taking in more energy. If the energy intake exceeds the daily energy consumption, it will be stored in the body in the form of fat, which will cause obesity over time.

Introduction:

1, avoid contact with air: oil often contacts with air, and the oxidation speed will be accelerated and deteriorated. It is suggested that when buying edible oil at ordinary times, you can repackage the oil in small dark bottles and jars, and immediately cover the bottle cap after each use to avoid deterioration due to excessive air contact. In addition, the shelf life of general edible oil is about 2 years, and it should be used within 3 to 6 months after opening the bottle to ensure freshness and safety.

2. Avoid contact with water: hydrolysis is one of the reasons for oil oxidation. High water content will accelerate the activity of oxidase and the hydrolysis speed will be faster. Moreover, water is also conducive to microbial reproduction, which will make oil rancid and deteriorate rapidly. Therefore, when opening the bottle mouth, it is necessary to avoid water falling into the bottle.
