Dietary Guidelines Recommendation for Dairy Increases Cancer Risk

Spread the love

dietary-guidelines-dairyResearch shows that three servings of milk a day can increase breast cancer risk by up to 80% and risk of death from prostate cancer by 141%.

But the Dietary Guidelines currently recommend up to three servings of dairy a day. It’s time for the upcoming 2020-2025 Dietary Guidelines for Americans to indicate that dairy is unnecessary.

The breast cancer study, which was funded by the National Cancer Institute, the National Institutes of Health, and the World Cancer Research Fund, followed 52,795 women who were part of the Adventist Health Study-2 cohort and found that women who consumed 1/4 to 1/3 cup of cow’s milk per day had a 30% increased chance for breast cancer. One cup per day increased the risk by 50%, and 2-3 cups were associated with an 80% increased chance of breast cancer. Replacing dairy milk with soy milk was associated with a 32% reduced risk of breast cancer.

When asked about the milk recommendations in the Dietary Guidelines, the lead author of the study, Gary E. Fraser, MBChB, PhD, said that “people should view that recommendation with caution.”

Research has also shown consuming cheese increases breast cancer risk.

The prostate cancer study found that those who consumed three or more servings of dairy products a day had a 141% higher risk for death due to prostate cancer compared to those who consumed less than one serving. Both high- and low-fat dairy products were associated with increased mortality. Previous research found an increased risk of prostate cancer for those who consumed ≥ 2.5 servings of dairy products per day, compared with those who consumed ≤ 0.5 servings a day.

Scientific evidence also shows that milk and other dairy products increase the risk of ovarian cancer, asthma, cognitive decline and early death, and offer little if any protection for bone health. Dairy products are also the No. 1 source of saturated fat in the American diet, which increases the risk of heart disease.

But last week, the Dietary Guidelines Advisory Committee (DGAC) released its scientific report that recommends that the 2020-2025 Dietary Guidelines for Americans continue to recommend 3 cups of dairy products daily. The U.S. Department of Agriculture and Department of Health and Human Services will use the scientific report to develop the Guidelines in the coming months.
