Cancer: foods to restore the gut microbiota after chemotherapies

Good intestinal health is related to important functions in the body, it is a fundamental part of a strong immune system and essential in the prevention of diseases, it is even related to the state of mind. The human colon is a sea full of life with millions of bacteria of hundreds of different species, in many cases an imbalance is related to infection or disease. Doctors and scientists around the world have studied a lot about the role that intestinal bacteria (also called microbiota, microbioma o flora intestinal) in many diseases, including cancer. In such a way that it is no secret to say that one of the main challenges for people with cancer is to maintain a good balance in the microbiota and it is associated with serious consequences: it delays the benefits of treatment, prevents the correct absorption of nutrients, causes effects delicate side effects and of course impairs recovery. Fortunately, there are some foods that will be essential for strengthen gut health and speed recovery.

Nutrition plays a role in approximately the 30% of cancer cases. Also, about a third of cancer could be prevented through a nutritious diet, maintaining a healthy weight, and regular exercise. After not smoking, excess weight is the leading preventable cause of cancer. That is why following a healthy lifestyle is key in recovering from treatment and a great help to reduce the risk of recurrence.

A normal bacterial balance occurs when there are many more good bacteria outnumbering the bad, and it is easier for a healthy person to make certain lifestyle adjustments that promote good gut health. However, it has been proven that Cancer in most cases tends to wreak havoc on the human microbiota. What happens is that the disease overloads the immune system and thus increases the risk of presenting a flourishing of bad bacteria in the intestine. There is also another very relevant factor: chemotherapyAlthough it is the most popular treatment to fight cancer and save lives, medical studies have shown that it is usually very aggressive and ends up killing all the good bacteria that intervene in digestion. That is why one of the main symptoms of chemotherapy is diarrhea, which generates a rather complicated picture since it depletes the good bacteria even more.

As if that were not enough, many of cancer patients take multiple antibiotics, which end up destroying the few remaining good bacteria. These can cause different infections, including the most notorious one being infection by Clostridium difficile, known simply as C. diff and characterized by inflammation in the colon. Often caused by alterations in the intestinal flora and a compromised immune system, it is estimated that this type of infection occurs in 10% of cancer patients.

How to reduce the effects of chemotherapy through diet?

To help reduce the effects of chemotherapy on the microbiome, one of the main recommendations of doctors and nutritionists is to bet on the consumption of prebiotics to strengthen the microbiota. And probiotics to restore the good bacteria lost or destroyed by the treatment. They are also a great ally to combat symptoms such as inflammation, gas, diarrhea and constipation, they are found in a wide range of fermented products and as daily supplements.

According to information released by the American Cancer Society and the American Institute for Cancer Research, after chemotherapy treatment it is essential to consume a balanced diet based on healthy fresh foods. Also the quality of the diet will be of great help to maintain a healthy weight and a balanced nutrition, in addition to accelerating the recovery after this aggressive treatment.

Recommended foods:
