What's the harm of eating too much oil?

Eating too much oil is not only a small problem of cooking methods and eating habits, but also a big problem related to health. Among all the foods that cause obesity, oil has the highest unit calorie, and 1 g can produce 9 kilocalories. If everyone eats 1 teaspoon (1.5g) of oil every day, they will gain 700-800g after one month, which is nearly10kg a year.

The incidence of hyperlipidemia, hyperglycemia, hypertension, coronary heart disease and cerebral infarction will increase. Eating more oil will lead to too much cholesterol and triglycerides in the blood. These excess cholesterol and triglycerides will adhere to and deposit on the blood vessel wall, causing arteriosclerosis and eventually forming thrombus.

Once the thrombus blocks the cardiovascular system, it will cause a heart attack; Once the cerebral vessels are blocked, the result is a stroke. In addition, excessive oil and water may also cause cancer. Some cancers, such as colon cancer, breast cancer and prostate cancer, are directly or indirectly related to eating too much oil. If you eat too much fat in your stomach, bile will increase secretion. When it enters the colon with high-fat and low-fiber food, some harmful bacteria in the colon can decompose bile into some carcinogens, thus increasing the risk of colon cancer.

Experts pointed out that the reason why the oil intake exceeds the standard is that most residents in our country eat vegetable oil for a long time, and they think that vegetable oil is harmless to people. "Oils and fats are divided into saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids.

These three fatty acids have important physiological functions for human body. Saturated fatty acids are the most abundant in animal oil and have a strong effect on raising cholesterol and low-density lipoprotein. Excessive intake will cause cardiovascular and cerebrovascular diseases. Monounsaturated fatty acids can not only reduce cholesterol and low density lipoprotein, but also reduce the incidence of cardiovascular diseases, among which olive oil is the most abundant.

Although polyunsaturated fatty acids can lower cholesterol, excessive consumption can easily lead to lipid peroxidation and affect immune system function. "Zhou Ming said. Zhou Ming said that although vegetable oil can provide more unsaturated fatty acids than animal oil, it can provide higher calories like animal oil. 1kg vegetable oil can produce 9000 calories, but the vegetable oil people buy every day contains more polyunsaturated fatty acids, and some vegetable oils also contain a certain amount of saturated fatty acids.

Therefore, vegetable oil should not be eaten too much. Eating too much can easily lead to a high incidence of various chronic diseases. Professor Qing of Jiangsu Nutrition Society further pointed out that if the consumption of oil exceeds the limit of human body's transformation function, oil will become fat and be deposited in the body, which will lead to the overload operation of fat transport system in fat cells. In the long run, it will easily lead to fatty liver, hypertension, diabetes, obesity and other diseases, which may eventually lead to colorectal cancer and breast cancer.
