What are unsaturated fatty acids

There are actually many types of unsaturated fatty acids. In our daily diet, there are many foods that are rich in unsaturated fatty acids, such as vegetables. The most common ones are onions, cauliflower, and leeks. These vegetables contain a lot of unsaturated fatty acids. People should consume some of these foods in moderation in their lives, so that the nutrition in their bodies can be more balanced.

The more common unsaturated fatty acids in nature are mainly divided into three categories: ω-9 series unsaturated fatty acids represented by oleic acid contained in tea oil, ω-6 series unsaturated fatty acids represented by linoleic acid contained in vegetable oils, and ω-3 series unsaturated fatty acids represented by EPA and DHA contained in fish oil. α-linolenic acid, which has strong biological activity, also belongs to the ω-3 series.

According to the number of double bonds: monounsaturated fatty acids MUFA & polyunsaturated fatty acids PUFA

According to the double bond position: ω-3 series & ω-6 series

1. Vegetables: garlic, onion, scallion, cauliflower, leek, ginger, radish, tomato, winter melon, kelp, and seaweed. Various mushrooms such as shiitake mushrooms and flower mushrooms. Soybeans and soy products: soybeans, adzuki beans, mung beans, broad beans, peas, kidney beans;

The caloric density of fat (1 gram = 9 kilocalories) is twice that of carbohydrates or protein (1 gram = 4 calories). Despite their health benefits, olive and canola oils are also high in calories (1 tablespoon = 120 calories). Additionally, many processed and fast foods are high in fat, especially saturated fat.

Polyunsaturated fats are found in safflower oil, inca inchi oil, tea oil, olive oil, argan oil, canola oil, sunflower oil, corn oil, and soybean oil. Saturated fat is found in animal products such as butter, cheese, whole milk, ice cream, cream and fatty meats, as well as some vegetable oils (coconut oil, palm oil and palm kernel oil).

Sea buckthorn seed oil is a typical unsaturated acid vegetable oil. Among all vegetable oils, the types and contents of unsaturated acids are quite high. It is also rich in natural stabilizer vitamin E. The natural stabilizer vitamin E can well control the easy deterioration property of unsaturated acids. It has strong stability and has quite high medicinal and edible value.
