A prospective study reports that survivors of advanced colorectal cancer (stage III) who regularly eat nuts: walnuts, hazelnuts, almonds have a risk of recurrence reduced by half.
One of the most important discoveries of recent years is the demonstration that lifestyle factors that prevent the development of cancer, whether it is the absence of tobacco, a good diet or physical activity regularly, can also play a predominant role in the prevention of recurrences. It is therefore possible to take concrete action to live a long and healthy life, even after a cancer diagnosis.
This is especially true when it comes to colorectal cancer. Several studies have shown that certain aspects of lifestyle can greatly reduce the risk of recurrence and thus increase the probability of surviving this cancer:
– Maintain a normal body weight: being overweight significantly increases the risk of recurrence of the disease.
– Exercising: the most active people after the diagnosis of cancer see their risk of premature mortality significantly reduced;
– Eat more plants and less red meat and cold cuts.
Halve the risk of onset and recurrence of colorectal cancer
It is now well established that the typical Western diet, high in saturated fats, added sugars and refined flours, but low in plant foods, is associated with an increased risk of several chronic diseases. This guy
This diet is especially bad for people with colorectal cancer: studies show that this type of eating habits triples the risk of death in these people, compared to those who adopt a healthier diet, low in red meats , but rich in plants. An increase in the consumption of plants, combined with a decrease in that of red meats and processed products, therefore represents an absolutely essential change in lifestyle for survivors of colorectal cancer who want to reduce their risk of recurrence.
The protective effect of nuts
If all plants are positive for health, the fact remains that recent studies indicate that some of them are particularly interesting in terms of preventing recurrences.
A study recently published in the Journal of the American Association of Clinical Oncology is an excellent illustration of this concept. In this prospective study, clinicians recruited 826 patients who had been treated for stage III colon cancer (surgery and chemotherapy) and examined the course of the disease over a period of approximately 7 years.
By analyzing the eating habits of patients during this period, they observed that people who regularly ate nuts (2 or more servings per week) had a 57% lower risk of mortality than those who did not. never. This effect is specific to nuts: walnuts, hazelnuts, almonds, cashews, pecans, etc.), while peanuts (which are legumes and not true nuts) do not seem to have a protective effect. According to the authors, the inclusion of nuts in dietary habits could therefore have extremely positive repercussions for the survival of people affected by colorectal cancer.
These observations show once again that it is important not to give up following a diagnosis of colorectal cancer: certain lifestyle changes, sometimes very simple (such as eating nuts regularly), can really influence the risk of recurrence and increase life expectancy.
