The attractive braised pork, the sweet cream cake... High-fat food always makes people love and hate it, making them irresistible. As everyone knows, the price of enjoying delicious food is very high. Let’s find out together with

The brain slows down. Studies have found that free saturated fatty acids in high-fat diets can lead to a decrease in the number of protein transporters in the blood-brain barrier, causing a lack of glucose in the hippocampus and cerebral cortex, leading to problems such as inattention and slow reaction.

Interfering with metabolism.

A high-fat diet will affect the molecular mechanism that controls the body's internal "clock", induce metabolic disorders, and lead to metabolic diseases such as diabetes and obesity.

Cause liver disease.

The lipids in high-fat foods activate immune cells and migrate to the liver, where they interact with cells in liver tissue and cause a series of liver diseases. For example, fatty liver disease is caused by excessive intake of fat, sugar, and lack of exercise. .

Cause inflammation.

High-fat foods are one of the key triggers of inflammation. Obesity caused by high-fat diet is usually accompanied by a series of inflammatory diseases, such as type 2 diabetes, cardiovascular disease, etc.

Injury to cardiovascular system.

Blood is the source of life, but many diseases are also closely related to blood. Eating high-fat foods for a long time can easily lead to thick blood and high blood lipids, induce atherosclerotic plaques and thrombi in blood vessel walls, lead to narrowing and thinning of the lumen, sluggish blood flow, and hypoxia and ischemia of body organs. If the energy supplied by fat in each person's daily diet exceeds 30% of the total daily energy, the prevalence and mortality of coronary heart disease will increase significantly. Saturated fatty acid intake is positively associated with coronary heart disease morbidity and mortality.

Induce cancer.

A high-fat, high-calorie diet also creates opportunities for breast cancer, intestinal cancer, gastric cancer, and esophageal cancer. Researchers from the Breast Cancer and Environmental Research Program at Michigan State University found that high-fat diets in adolescent girls increase the risk of breast cancer and accelerate its progression. In addition, some studies have found that a high-fat diet can disrupt the flora in the intestines and cause intestinal cancer.

So, how do we deal with the ubiquitous high-fat foods?

First of all, when eating meat, fish is the first choice, followed by poultry, and livestock meat third. Ensure a total intake of 2 to 3 taels of meat food every day, and eat less processed meat products such as ham and sausages.

Secondly, discern the subtleties and find out the invisible fat. What is most easily overlooked by us are animal internal organs, such as liver, tripe, intestines, etc. In order to avoid excessive intake of cholesterol and fat, the intake of animal offal must be controlled. Among delicious seafood, squid and eels have higher cholesterol content. The cholesterol in shrimps, crabs, sardines and clams is concentrated in the heads and yolks. These two parts should be removed when eating.

Again, cooking method is important. Eat less food such as grilled squid on a teppanyaki plate, and use steaming, boiling and other methods with less oil and less salt for daily cooking. Reduce eating out. Surveys show that some vegetarian dishes in restaurants contain alarming amounts of oil. A plate of lettuce (raw weight: 500 grams) can contain an average of 50 grams of oil, and the daily intake of cooking oil per person should not exceed 30 grams. . If you eat out, be sure to ask "put less oil".
