The misunderstanding between cholesterol and ketogenic diet

The misunderstanding between cholesterol and ketogenic diet


The misunderstanding between cholesterol and ketogenic diet.  Cholesterol has been demonized for many years. When most people hear it, they think it is a bad thing, but cholesterol is very important to the human body.

Ketogenic diet, this high-fat low-carb diet will lead to increased cholesterol?

Cholesterol has been demonized for many years. When most people hear it, they think it is a bad thing. In fact, most of the cholesterol in the human body is produced by your own body, not by diet. Therefore, cholesterol is very important to the human body.

1. What is cholesterol and why do we need it?

Cholesterol is a substance in the structure of the human body and a kind of lipid substance, which is vital to life. It plays an important role in maintaining the integrity of body cells. Cholesterol is used to make hormones such as vitamin D, testosterone, and estrogen. It is also necessary for the production of bile acids that help digest fat.

Your liver, intestines and other organs produce most of the cholesterol in your body. In addition, it can be obtained by eating animal foods such as meat, cheese, eggs and butter.

Many experts believed that high cholesterol would cause cardiovascular and cerebrovascular diseases, heart disease, etc. many years ago. However, since 1977, various versions have included the concept of restricting cholesterol intake: “The daily recommended intake of cholesterol should not exceed 300. Milligrams”, and in the latest version of “Key Recommendations”, any restrictions have indeed been lifted.

 

2. What is the relationship between blood cholesterol and disease?

Historically, elevated blood cholesterol levels have been thought to be related to atherosclerosis. Atherosclerosis is a disease in which plaque deposits cause the intima of the arteries to thicken and may affect the blood flow to the heart. The process of plaque deposition is complex, but it involves the accumulation of white blood cells, calcium, cholesterol, and other substances in inflamed or damaged arteries.

However, cholesterol does not flow in your blood by itself. Due to the hydrophobic nature of cholesterol, it must be transported through a special carrier called lipoprotein. Different types of lipoproteins flow in your blood and are formed when you lower or absorb triglycerides and cholesterol.

3. Low-density lipoprotein (LDL)

Often referred to as “bad” cholesterol. The role of LDL is to transport energy and nutrients through the blood and deliver them to the cells that need them. Low-density lipoprotein particles provide cells with triglycerides as an energy source, and cholesterol as needed for repair and other functions. However, LDL is easily oxidized, and oxidized low-density lipoproteins can cause inflammation, leading to the accumulation of plaque on the arterial wall.

4. High-density lipoprotein (HDL)

Often referred to as “good” cholesterol. HDL is generally considered a good thing because it transports cholesterol from your body to the liver, breaking it down into waste or recycling it. High-density lipoprotein has anti-inflammatory properties and has many benefits for the immune system.

5. A ketogenic diet can regulate “good” cholesterol

Hussein M Dashti and others conducted a 24-week ketogenic diet study involving 83 obese patients and measured their body weight, body mass index, total cholesterol, low-density lipoprotein, high-density lipoprotein, and triglycerides before and after the diet. , Fasting blood glucose, urea, creatinine levels.

The results found that: the patient’s weight and body mass index decreased significantly. The total cholesterol level began to decrease after 1 week of diet intervention. After treatment, the high-density lipoprotein cholesterol level increased significantly, while the low-density lipoprotein cholesterol level decreased significantly. After 24 weeks of treatment, triglyceride levels and blood sugar levels were significantly reduced. The changes in urea and creatinine levels were not statistically significant.

6 Conclusion

The ketogenic diet can help you adjust your cholesterol levels in your body. However, it should be noted that the ketogenic metabolism increases the burden of the liver and kidneys, and there is still a certain risk for patients with liver and kidney diseases. Therefore, consult your doctor before taking a ketogenic diet.
