According to a new study published in the journal Nature, people with lactose intolerance have a reduced risk of developing lung, breast and ovarian cancers, according to the Internet publication for girls and women aged 14 to 35 Pannochka. net Previous studies have shown that in different parts of the planet the frequency of ovarian cancer varies greatly.
Experts know that the highest incidence of ovarian cancer in North America, Western Europe and Scandinavia, and the lowest in Eastern and Central Africa.
Studies of twins' health and immigrant health studies suggest that these differences are due to environmental factors rather than genetic and ethnic moments.
The high level of dairy consumption in North America and Eastern Europe, according to some scientists, may be a factor in the spread of ovarian cancer in these territories.
Nevertheless, the conclusions of the studies that have been devoted to this issue are ambiguous. These include a recent large-scale review conducted by the World Cancer Research Fund and the American Institute of Cancer Research,.
The authors of the latest study from Lund University in Sweden used a slightly different approach to the study of the alleged link between milk consumption and cancer. They examined how the restriction of dairy products in individuals with lactose intolerance affects the incidence of different types of cancer.
Lund University Professor Jianguang Ji, Research Fellow, Center for Primary Care Studies in Malmo, comments on the results of the study: "Using national data from Swedish registries of outpatient and inpatient patients, we identified 22,788 patients with lactose intolerance and assessed their risk of lung cancer , breast and ovaries. The risk of lung cancer (the standardized SIR value of 0.55), breast cancer (SIR 0.79) and ovarian cancer (SIR 0.55) was significantly lower in people with lactose intolerance, regardless of country of birth and sex.
For comparison, the risk of cancer in siblings and parents was the same as in the general population. This suggests that a reduction in the risk of cancer in people with lactose intolerance is associated with the diet.
In other words, the team found that people who do not consume dairy products reduce the risk of just three types of cancer. Since their blood relatives with lactose intolerance risk remain high, this suggests the effect of diet, rather than the disease itself.
Jinguan Ji draws attention to the fact that their conclusions may be erroneous. For example, people with lactose intolerance can simply eat fewer calories or drink milk drinks on a plant basis - both of these are associated with a reduced risk of cancer. Therefore, milk can have nothing to do with it..
"We should interpret the results with caution, because the relationship we identified is not enough to charge dairy products with cancer.
To identify other possible factors, further research will be required, "writes Jiangguang Ji.
Indeed, if you have not heard for the first time about the connection between milk and cancer, this question seems rather confusing. In 2012, Lund University staff have already stated that the use of milk can slow the progression of bowel cancer. They then found that milk protein Lactoferricin 4-14 promotes DNA repair and slows down the division of tumor cells of colorectal cancer.
