The scientists are set off by the fact that one of the causes of the breast cancer may be the inflammation triggered by harmful bacteria . The yogurt - researchers say - contains beneficial bacteria, attenuate inflammation and are similar to those present in mothers breast-feeding . “We now know that breast milk is not sterile and that lactation alters the microflora of the breast,” explains Rachael Rigby the Department of Health and Medicine at the University of Lancaster. "The bacteria that ferment the lactose commonly found in milk and can occupy the ducts and the mammary of women during lactation and for a period not yet defined even after". A link to the allamento? According to experts at the University of Lancaster, these bacteria are protective given that each year of breastfeeding reduces the risk of breast cancer by 4.3%. But it is a deduction scientifically valid? “In reality – explains Saverio Cinieri , president-elect of the Italian Association of medical oncology (Aiom) - it is not clear why breast-feeding reduces the risk of breast cancer. This is only a hypothesis, but at the moment it is not supported by scientific evidence” certain". The link between the consumption of milk and dairy products, and the tumor is at the center of numerous scientific studies and meta-analysis. And any other evidence in support of the thesis of the researchers of Lancaster there is. In 2017, for example, researchers at the Rosswell Park Cancer Institute, Buffalo (NY) have published the findings of a study in which they were monitored the daily consumption of dairy products in a population of 1941 women with breast cancer compared with a control population of 1237 women. The results obtained were evaluated statistically and adjusted on the basis of variables such as age, race, body mass index, smoking, physical activity, type of dairy products consumed usually and familiarity for cancer of the breast. “The study explains, Cinieri - has shown that the consumption of yogurt constant reduces the risk of breast cancer of 15% and that, on the contrary, a high consumption of Cheddar cheese is very common in America) and cream cheese spreads, they increase the risk in a consistent way”.
Serves prudence: the research should be further explored More recently was published in the journal BMJ Open a review in which the authors conclude that the quality of these jobs is still not enough. For example, some studies show a decreased risk for cancers of the gastrointestinal tract (esophagus, stomach, pancreas, and colon-rectum) associated with the consumption of dairy products, while others do not find significant links. For cancers that depend on hormones (prostate, breast, endometrium, and ovary), the results are even more heterogeneous and the same is true for cancers that affect the kidney, thyroid, and lung. A review of the published literature on the Scientific Report in 2016 has failed to identify any significant association between the consumption of dairy products and risk of cancer of the lung, while a more recent study published in JAMA Oncology suggests that yogurt may protect you from the risk of developing this type of cancer, especially thanks to prebiotics and probiotics contained in it. In short, there are still no certainties. Yogurt or milk every day? Since the doubts are still so many, how to behave with the consumption of these products? In the journal Medical Hypotheses where it was published in their study, the researchers from Lancaster suggest: “There is a potential remedy prior to the reach of all women and the economic is to consume natural yogurt every day.” But many women – especially if they have already had a breast cancer – are reluctant to consume milk and dairy products because they are even convinced that they can encourage the onset of cancer. And then? “We should not demonize these products, but put them to good use,” warns Cinieri. “In general, the council the consumption of a glass of milk a day to the patients in treatment for the tumour, but also to those without a cancer diagnosis . For all it is important to do not neglect the health of the bone especially during the menopause which is a phase characterized by the deprivation of calcium in the bones and one of the things that can help is the consumption of milk and dairy products”. And to the women who have misgivings or do not like? “Then you can opt for a jar of yogurt or a slice of parmesan cheese per day ”, concludes Cinieri, who also directs the department of Oncology of the ospedale Perrino Brindisi.

Guidelines for a healthy diet The rest, even the guidelines for a healthy diet of the Italian Council for research in agriculture (CREA) just updated and the Italian Society of human nutrition (UNEMPLOYMENT) recommend 3 daily servings of milk or yogurt (a portion corresponding to 125 ml milk or 125 g yogurt), to which you should add 2 to 3 servings per week of fresh cheese (100 g each) or aged (50 g).
