A high-fat diet harms various organs

Fried chicken chops, kebabs, hamburgers, butter cakes... these foods can make people mouth-watering just thinking about them. In an era when various cuisines are "competitively competing for beauty", high-fat diets often dominate people's taste buds. Many people still cannot sustain themselves even at the risk of their health being eroded little by little.

A high-fat diet will manipulate the human brain

In fact, the "greed" high-fat diet may not be your fault. A study recently published by Yale University in the United States showed that a high-fat diet "manipulates" the brain-stimulates inflammation in the hypothalamus and induces the body to take in more calories, causing people to eat more and more cravings, eventually gaining weight and disease Struck. What is even more surprising is that this kind of neuroendocrine change in the brain is "menacing" and will have an impact after eating for 3 days.

The process by which a high-fat diet "manipulates" the brain is out of our control. The central nervous system of the brain plays an important role in energy and sugar metabolism, among which the hypothalamus is particularly prominent and is the "command headquarters" that controls metabolism. After 3 days of a high-fat or high-carb diet, inflammation of the hypothalamus will appear. At the same time, microglia are also activated, which can further activate the neurons in the brain that control appetite and make people want to eat more high-fat foods. In this way, it will enter a vicious circle, which is why a high-fat diet tastes particularly good.

Hurt the internal organs all over

In addition to desserts and fast-food high-fat foods, the intake of oil in the daily diet is not low.

Brain: The effect of a high-fat diet on the brain is by no means as simple as appetite control. The above-mentioned Yale University study shows that inflammation caused by a high-fat diet is a persistent low-grade inflammation. Although the brain has a certain ability to repair itself, as long as you maintain a high-fat diet, inflammation will always exist and cause damage to the brain. Studies have also found that free saturated fatty acids in a high-fat diet can reduce the number of protein transporters in the blood-brain barrier, causing the hippocampus and cerebral cortex to lack glucose, causing problems such as inattention and slow response.

Cardiovascular and cerebrovascular: Gong Xionghui introduced that a high-fat diet can damage the vascular endothelium, form atherosclerotic plaques, and cause hyperlipidemia, hypertension, and cardiovascular and cerebrovascular diseases. In addition, blood clots block blood vessels, which can easily lead to myocardial ischemia, hypoxia, and even sudden death.

Pancreas: "In recent years, acute pancreatitis caused by high blood lipids is more common." Gong Xionghui said that more fat intake will hinder blood flow, thereby affecting the microcirculation of pancreatic blood vessels, leading to insufficient blood supply and pancreatitis. A high-fat diet also accelerates the renewal of pancreatic cells, thereby increasing its sensitivity to carcinogens.

Gallbladder: The high incidence of gallstones is inseparable from a high-fat diet. Gong Xionghui told reporters that if too much fat is ingested, blood cholesterol levels will rise, and bile components will become abnormal, resulting in cholesterol supersaturation, followed by crystals, and gradually forming gallstones.

Liver: Research by the Helmholtz Munich Research Center in Germany found that high-fat foods increase fat accumulation in the liver, leading to a series of liver diseases such as hepatitis, non-alcoholic fatty liver, and severe liver failure. In addition, non-alcoholic fatty liver is often accompanied by insulin resistance, which increases the risk of type 2 diabetes and cardiovascular disease.

Intestine: Long-term high-fat diet will cause long-term and continuous changes in the large intestine micro-ecosystem. When the fat content in the blood increases, the environment in which the intestinal microorganisms live is changed, which affects the metabolism and growth, and reproduction of the flora, significantly reducing the number of beneficial bacteria and increasing harmful microorganisms. In addition, Gong Xionghui told reporters that a high-fat diet will increase the risk of colorectal cancer. People who regularly eat high-fat foods have a risk of colorectal cancer 2 to 3 times that of others.

Stomach: To digest high-fat foods, the human body needs to secrete more stomach acid, which increases the risk of pantothenic acid, which can easily cause stomach diseases in the long run.

It must be delicious and healthy

In addition to being an important way to supplement the nutrients needed by the human body, diet is also an important way for people to obtain a sense of pleasure and satisfaction. If only for the pursuit of nutrition, reject all delicious food, it will cause psychological loss, and will greatly reduce health and life satisfaction. How to eat healthy and delicious is a topic of long-term concern. In terms of a high-fat diet, experts suggest that the following points should be paid attention to:

1. Don't eat continuously. Most of the injuries of a high-fat diet are caused by continuous intake and accumulation of fat. It is recommended not to eat frequently and continuously. It is best to eat light food for a few days after each high-fat diet to avoid the accumulation of fat and reduce the burden on various organs of the body. .

2. Pay attention to the proportion of meat and vegetables. Although a high-fat diet has many hazards, it is not possible to avoid eating any fat at all, let alone to quit meat that is rich in protein needed by the human body. Vegetables can provide the human body with rich dietary fiber and vitamins, and make up for the defects of high saturated fatty acids and high cholesterol in meat dishes. The dietary guidelines for Chinese residents recommend that 300 to 500 grams of vegetables and 120 to 200 grams of fish, poultry, meat, eggs, and other animal foods should be eaten every day. Therefore, the meat and vegetable ratio of the whole day's dishes can be arranged according to 1:3 or 1:4.

3. The reduction cannot be done overnight. In northern China, where the climate is cold, it is usually necessary to eat more high-fat foods to supplement energy. In response to this situation, Gong Xionghui suggested that instead of changing your eating habits all at once, you should gradually reduce your fat intake, or reduce your intake of red meat (such as pork, beef, and lamb) and replace it with white meat (such as chicken and fish). So as not to adapt to the body. You can also change to a healthy way of cooking, such as changing frying and grilling to stewing and steaming.

4. The elderly should eat less. As age increases, the various functions of the body of the elderly gradually decline, and the digestion and metabolism functions weaken. It is best to keep a light diet and reduce the intake of high-fat foods. In addition, the elderly should continue to exercise to accelerate fat consumption and reduce the damage it causes to the body.
