Liver cancer is one of the most common cancers worldwide, and it is the fourth leading cause of cancer-related death globally.
In the United States, it is the fifth most common cause of cancer death in men and the eighth most common cause of cancer death in women. The risk factors for liver cancer include chronic hepatitis B and C, alcohol abuse, obesity, and nonalcoholic fatty liver disease (NAFLD).
It is becoming increasingly clear that diet is a key factor in the development of liver cancer. Several studies have shown that high fiber intake is associated with a reduced risk of liver cancer.
This article will explore the link between fiber and liver cancer and explain how fiber can help prevent this deadly disease.
The Role of Fiber in the Body
Dietary fiber is a type of carbohydrate that cannot be broken down by the body’s digestive enzymes. Instead, it passes through the digestive system relatively intact. There are two main types of fiber: soluble and insoluble.
Soluble fiber dissolves in water and forms a gel-like substance in the digestive tract. This type of fiber helps to lower cholesterol levels and regulate blood sugar levels. Good sources of soluble fiber include oatmeal, apples, and beans.
Insoluble fiber does not dissolve in water and adds bulk to the stool. It helps to prevent constipation and may reduce the risk of colon cancer. Good sources of insoluble fiber include whole grains, nuts, and vegetables.
The Link Between Fiber and Liver Cancer
Several studies have shown that a high-fiber diet can reduce the risk of liver cancer. One study published in the Journal of Hepatology in 2016 found that a high-fiber diet could reduce the risk of liver cancer by up to 40 percent.
Another study published in the Journal of Clinical Oncology in 2018 found that a high-fiber diet was associated with a lower risk of death among patients with liver cancer.
The study followed 461 patients with liver cancer for a period of five years and found that those who consumed more fiber had a higher survival rate compared to those who ate less fiber.
So, how does fiber help prevent liver cancer? One theory is that fiber can help regulate the microbiome in the gut. The microbiome is the collection of bacteria and other microorganisms that live in the digestive tract.
A healthy microbiome is essential for good health, and an imbalance in the microbiome has been linked to several diseases, including liver cancer.
Fiber acts as a prebiotic, which means it provides food for the good bacteria in the gut.
When the good bacteria in the gut are fed, they produce short-chain fatty acids (SCFAs), which have anti-inflammatory properties and may help prevent the development of liver cancer.
Other Ways Fiber Can Benefit the Liver
Fiber may also benefit the liver by reducing the risk of NAFLD, a condition that occurs when there is too much fat in the liver. NAFLD can lead to inflammation, scarring, and eventually, liver cancer.
Several studies have shown that a high-fiber diet can help prevent and treat NAFLD.
One study published in the Journal of Gastroenterology and Hepatology in 2018 found that a high-fiber diet could improve liver function and reduce inflammation in patients with NAFLD.
Fiber may also help to reduce the risk of liver cancer by reducing insulin resistance. Insulin resistance is a condition in which the body is unable to use insulin properly. This can lead to high blood sugar levels and an increased risk of liver cancer.
A high-fiber diet can help regulate blood sugar levels and reduce insulin resistance.
How to Increase Your Fiber Intake
If you want to increase your fiber intake to reduce your risk of liver cancer, there are several things you can do. First, try to eat more fruits and vegetables.
These foods are high in both soluble and insoluble fiber and are also rich in vitamins, minerals, and antioxidants.
Second, incorporate more whole grains into your diet. Whole grains, such as brown rice, oatmeal, and whole wheat bread, are high in fiber and also contain other nutrients that are important for good health.
Finally, eat more legumes, such as beans, lentils, and chickpeas. These foods are an excellent source of both soluble and insoluble fiber and are also high in protein.
Conclusion
Dietary fiber plays an important role in the prevention of liver cancer. Several studies have shown that a high-fiber diet can reduce the risk of liver cancer and improve the survival rate of patients with liver cancer.
Fiber may help prevent liver cancer by regulating the microbiome in the gut, reducing the risk of NAFLD, and reducing insulin resistance. To increase your fiber intake, try to eat more fruits and vegetables, whole grains, and legumes.
