Shortening is a common cooking oil, mostly used in the preparation of cakes, puffed foods and other foods. Generally speaking, shortening is not harmful when consumed in moderation, but when consumed in large quantities, it may cause certain effects on the body, such as obesity, cardiovascular disease, hyperlipidemia, type 2 diabetes, etc. 1. Obesity: shortening itself contains high calories, and consuming large quantities of shortening or foods containing shortening may result in excessive caloric intake, which may increase the risk of obesity in the long run. 2. Cardiovascular diseases: shortening contains a large amount of trans fatty acids, which are not easily digested and absorbed by the body. Shortening or foods containing shortening can increase fat intake, and fat is often transported through the bloodstream, so long-term intake of large amounts of fat can lead to increased fat content in the blood, which can lead to hyperlipidemia; 4. increase the risk of developing type 2 diabetes. Therefore, it is recommended to consume shortening and shortening products in moderation according to your needs in daily life.
