Tag: Milk and hormones

According to a 2019 study published in *Public Health Nutrition*, conventional milk was found to have levels of bovine growth hormone (bGH) up to 20 times higher than organic milk, suggesting a significant difference attributable to farming practices. This raises important questions about whether and how organic milk affects hormones in the human body compared to its conventional counterpart.

According to a review published in BMC Cancer, total dairy product consumption has been shown to reduce breast cancer risk in some populations, but the specific type of dairy and the consumer's hormonal status matter significantly. The question of whether milk source affects estrogen levels is nuanced, involving both animal physiology and the complexities of plant compounds.

Recent studies from fertility clinics suggest a significant difference in how different types of dairy affect male fertility. Specifically, low-fat milk has been positively associated with improved sperm concentration and motility, while full-fat dairy may have the opposite effect. Understanding this distinction is key to optimizing diet for reproductive health.
