What are saturated fatty acids and unsaturated fatty acids?
The difference between saturated fatty acids and unsaturated fatty acids mainly lies in their chemical structures. Saturated fatty acids contain no double bonds, and unsaturated fatty acids contain double bonds. Saturated fatty acids mainly come from animal fats and dairy products, such as lard, butter, cream, butter and so on. Unsaturated fatty acids mainly come from vegetable oils, such as linseed oil, olive oil and corn oil.

Saturated fat is also a nutrient that the human body needs, but the demand of the human body is not much, and our daily intake is often seriously exceeded, especially for people who like to eat animal food. Excessive intake of saturated fat will easily lead to hyperlipidemia and high cholesterol, which will lead to obesity, arteriosclerosis and other problems, and increase the risk of cardiovascular and cerebrovascular diseases.

The difference between saturated fatty acids and unsaturated fatty acids:

1, with different properties:

Saturated fatty acids. Fatty acids without unsaturated double bonds are called saturated fatty acids.

Unsaturated fatty acids. Fatty acids other than saturated fatty acids (fatty acids without double bonds are called saturated fatty acids, and the main fatty acids of all animal oils are saturated fatty acids except fish oil) are unsaturated fatty acids.

2, the food is different:

Saturated fatty acids. Generally speaking, animal fats such as butter, cream and lard contain more saturated fatty acids than plant fats. But it is not absolute. Coconut oil, cocoa oil and palm oil are also rich in saturated fatty acids. Animal foods contain the most fat, and most of them are saturated fatty acids.

Unsaturated fatty acids. Vegetables include garlic, onion, green onion, cauliflower, leek, ginger, radish, tomato, wax gourd, kelp and laver. Mushrooms, flower mushrooms and other mushrooms. Soybean and bean products are soybean, adzuki bean, mung bean, broad bean, pea and kidney bean; Fish include soft-shelled turtles and various marine fish; The fruit is pomegranate, vegetables and fruits, hawthorn and orange; Milk is yogurt and so on.
