Intestine cancer, in particular colon cancer, has become one of the fastest-growing malignant tumours in recent years. However, scientific research has shown that improved dietary habits can effectively reduce the risk of intestine cancer. As a highly recommended healthy food, yogurt is considered to have a potential role in the prevention of intestine cancer in recent years because of its prophylactic bacteria and multiple nutrient components. So how does yogurt help to protect intestinal health? What are the scientific grounds behind these effects?
I. Relationship of intestine cancer to diet
Intestine cancer occurs as a result of a combination of factors, including genetic, chronic inflammation, environmental pollution and unhealthy diets. High-fat, low-fibrous Western eating habits in the diet can lead to an imbalance in intestinal strains, increase the proportion of harmful bacteria and promote the formation of carcinogenic substances (e.g. nitrousamine). In addition, chronic inflammation and impaired intestinal barrier functions provide “hotbeds” for the growth of cancer cells.
In this context, yoghurt, rich in fungi and lactating, has become the focus of scientists. It has been found that yogurt contributes to the improvement of the intestinal microecological environment and reduces the response to intestinal inflammation, which may have some effect on the prevention of intestinal cancer.
“Secret weapons” in yogurt
1. Vegetable fungi-regulated intestinal strains
The core components of yogurt are prophylactic bacteria (e.g., lactate and trobacteria), which are essential for the maintenance of intestinal health. Healthy intestinal strains can:
Influencing of harmful bacteria: Prophyxia competes in the inner walls of the intestinal tract and inhibits the growth of potentially pathogenic bacteria such as coli and aerobic membrane.
Balanced immune system: Prophyxia can stimulate intestinal immunosuppressors and reduce the incidence of chronic inflammation, which is particularly critical to preventing cancer.
To reduce the generation of toxins: The fungi can decompose or convert carcinogens (e.g. nitrites) in the intestinal tract.
2. Reduction of carcinogenic risk from lactate
yogurt is very lactated and this metabolite can reduce intestinal pH and thus inhibit the reproduction of certain carcinogenic bacteria. In addition, lactate promotes the generation of short-chain fatty acids (e.g., butate), a material that is extremely beneficial to intestinal cells.
3. Protection of short-chain fatty acids
Butate is an important metabolite produced by mucular metabolic fibres capable of:
Energy for upper intestinal skin cells and repair of intestinal wall damage;
Influencing the release of inflammatory factors and reducing chronic inflammation;
Regulate genetic expression and inhibit the growth and transfer of cancer cells.
Evidence of scientific research
In recent years, several studies have supported the cancer resistance potential of yogurt. The following are representative results:
epidemiological studies at Harvard University, USA
A study published in the Journal of the American Medical Association (JAMA) investigated the relationship between dietary habits and the incidence of enteric cancer among over 120,000 men and women. As a result, it was found that men who consumed a glass of yogurt (approximately 150 grams) a day were at a significantly reduced risk of rectal cancer. This association is considered to be related to yogurt improvement of intestinal strains and reduction of inflammation levels.
Laboratory research in Japan
Japanese scientists have found, through animal experiments, that lactacid bacteria can contain intestinal inflammation and reduce the incidence of tumours. In addition, the protection of yogurt was further demonstrated by the significant increase in intestinal short-chain fatty acid levels in mice from the experimental group after ingestion of the fungi.
Europe’s Synthesis Study
An overview of European research on dairy and intestine cancers points out that fermented dairy products (including yogurt) may have some cancer-resistant effects because of their abundance of fungi and lactation acid. However, the authors also stress that this role may vary from individual to individual.
IV. How to protect intestinal health through yogurt?
In order to maximize the health benefits of yogurt, the following recommendations can be considered in the daily diet:
Choose a good yogurt.
Priority is given to natural yogurt without sugar and low fat. The sour milk added with too much sugar is not only high in heat but may also interfere with the balance of the intestinal population.
A mix of dietary fibres
Bountiful bacteria require dietary fibres (Living Dollars) as “consumer”. yoghurt can be fed with high-fibre foods such as fruit and oats to promote prophylactic activity.
Hold on to appropriate intake.
A glass of yogurt (approximately 150-200 g) per day is sufficient to meet the demand for the bacterium and is not recommended for overdose to avoid indigestion.
People are different.
For lactose intolerant or emulsifiable, a plant-based yogurt or bacterium-resilient supplement may be selected as an alternative.
V. Can yogurt completely prevent intestinal cancer?
Although yogurt is active in intestinal health and in the prevention of intestinal cancer, a single food product cannot fully prevent intestinal cancer. A truly effective prevention strategy includes:
A balanced diet: multi-ingestion of vegetables, fruits and whole grains, reduced intake of red meat and processed meat.
Regular exercise: maintenance of healthy weight and enhancement of immune functions.
Regular screening: Early screening and colonoscopy are essential for people with family history or other high-risk factors.
Concluding remarks
It is true that yogurt has many benefits for intestinal health and, to a certain extent, helps to reduce the risk of intestine cancer because it is rich in fungi and lactate. However, the prevention of intestinal cancer requires a combination of factors, including healthy eating habits, positive lifestyles and early screening. By scientifically and rationally integrating yogurt into our daily diet, we not only enjoy its good taste, but also add a guarantee of intestinal health.
