UNITED STATES (OBSERVATORY NEWS) — Cow’s milk, so rich in protein and calcium, has long been considered a useful product. So, according to the official recommendations of American nutritionists, an adult should consume three cups of milk per day.
However, US scientists urge women to take this advice with caution. A recent study showed that consumption of milk of animal origin is associated with an increased risk of developing breast cancer.
Almost 53 thousand women from North America took part in the new work (29.7% of them were dark-skinned). Their average age was 57 years. At the start of the study, participants did not have cancer.
Women several times a week filled out questionnaires in which they talked about their diet, as well as physical activity, alcohol consumption, hormones and other drugs. In addition, specialists took into account the results of screening for breast cancer, the reproductive health of patients, as well as a family history (what kind of diseases relatives had).
The follow-up period was eight years. During this time, 1,057 cases of breast cancer were reported.
After analyzing all the data and risk factors, the authors did not find a correlation between the use of soy, almond or oat milk and the risk of developing breast cancer.
Meanwhile, consumption of cow’s milk (whole, low-fat and non-fat) was associated with an increase in these risks.
So, when drinking from a quarter to a third of a glass of such milk per day, the likelihood of developing breast cancer increased by 30%. When consumed, up to one cup per day (240 milliliters) – by 50%. And for those women who drank two or three cups of milk a day, the risk increased by 70-80%.
At the same time, scientists did not reveal significant correlations between the consumption of a large number of dairy products, in particular cheese and yogurt, and the risk of developing this cancer.
According to scientists, the obtained data are explained by the presence of sex hormones in milk of animal origin. Breast cancer is known to be hormone-sensitive.
In addition, the consumption of dairy and other animal proteins is also associated with a higher level of insulin-like growth factor-1 in the blood , which is believed to contribute to the development of certain types of cancer.
Researchers believe that women can reduce the likelihood of developing breast cancer if they replace regular milk with “alternative” milk.
By the way, this version is supported by another study, which showed that women who do not consume any animal products (i.e. strict vegans) have a lower risk of developing breast cancer than women who have ovo lacto vegetarianism (consuming milk and eggs).

Note that this work was done by scientists from Loma Linda University , which was founded by Seventh-day Adventists. They adhere to Old Testament beliefs about prohibited foods and promote vegetarianism.
