Milk is an essential source of nutrients for infants, and mothers who breastfeed their babies are often encouraged to drink milk to ensure their milk production is sufficient. However, recent studies have shown that milk may contain “forever chemicals” that can have adverse effects on mothers and infants’ health. In this article, we will explore what forever chemicals are, how they get into milk, their impact on health, and current research on milk forever chemicals in mothers.
What are Forever Chemicals?
Forever chemicals, also known as per- and polyfluoroalkyl substances (PFAS), are a group of man-made chemicals that have been used in various industrial processes, such as manufacturing, firefighting, and oil and gas exploration, for decades. They are called “forever chemicals” because they do not break down easily in the environment and can accumulate in human tissue over time.
Studies have shown that PFAS can be found in many household products, including non-stick cookware, food packaging, and carpets. They are also found in the environment, including water sources, soil, and air. As a result, most people are exposed to PFAS to some extent. However, certain populations, such as firefighters and communities near PFAS manufacturing plants, may have higher exposure levels.
Furthermore, PFAS have been detected in breast milk, raising concerns about their impact on infants’ health. Given that breast milk is the primary source of nutrition for infants, it is crucial to understand how PFAS get into milk and what impact they can have.
How do Forever Chemicals Get into Milk?
Forever chemicals can enter the milk supply through various pathways, including from the environment or from the mother’s diet. PFAS can accumulate in the soil and water, which can then be ingested by cows or other animals that produce milk. Additionally, PFAS can be found in animal feed or supplements given to cows, further increasing the exposure levels in milk.
Moreover, PFAS can also enter the mother’s bloodstream through the air, water, or food that she ingests. Once in the body, PFAS can accumulate in fatty tissues and be released into breast milk. Therefore, the levels of PFAS in breast milk are often higher than in the mother’s blood.

Other factors can also affect the levels of forever chemicals in milk. For example, the age of the mother, her body mass index (BMI), and the duration of breastfeeding can all impact the levels of PFAS in breast milk. Studies have shown that older mothers and those with higher BMIs tend to have higher levels of PFAS in their breast milk. Additionally, longer breastfeeding duration can result in higher PFAS levels in milk.
The Impact of Forever Chemicals on Mothers and Infants
Forever chemicals can have varying effects on human health, and their impact on mothers and infants is a growing concern. Studies have shown that exposure to PFAS can lead to adverse health effects, including developmental delays, decreased immune function, and increased risk of cancer and other diseases.
Infants are particularly vulnerable to PFAS exposure, as their developing bodies are more susceptible to the chemicals’ harmful effects. For example, PFAS exposure has been linked to lower birth weights and reduced head circumference in infants. Additionally, PFAS exposure in infancy can lead to long-term health effects, such as impaired cognitive function and increased risk of obesity.
In mothers, PFAS exposure can also have adverse health effects, such as reduced fertility, increased risk of hypertension, and liver damage. Moreover, PFAS can accumulate in the body over time, leading to long-term health effects that may not be immediately apparent.
Overall, the impact of forever chemicals on mothers and infants is a growing concern and highlights the need for continued research to better understand the health effects of PFAS exposure.
Current Research on Milk Forever Chemicals in Mothers
Several studies have been conducted to understand the levels of PFAS in breast milk and their potential impact on infants’ health. A study published in Environmental Science & Technology in 2020 found that PFAS were present in all breast milk samples collected from women in the United States. The study also found that the levels of PFAS in breast milk were higher in women who lived near PFAS manufacturing plants or had higher levels of PFAS in their blood.
Another study published in Environmental Health Perspectives in 2019 found that infants who were exposed to higher levels of PFAS through breast milk had lower antibody responses to vaccinations at 7 months and 12 months old. This suggests that PFAS exposure through breast milk may impact the immune system’s ability to respond to vaccines.
While these studies provide valuable insights into the levels of PFAS in breast milk and their potential impact on infants’ health, there are limitations to the research. Most studies have relied on small sample sizes and have not accounted for all potential confounding factors. Additionally, more research is needed to understand the long-term health effects of PFAS exposure through breast milk.
Conclusion and Future Directions
The presence of forever chemicals in breast milk is a cause for concern, as it raises questions about the potential impact on infants’ health. While current research has shed light on the levels of PFAS in breast milk and their potential impact, more research is needed to understand the long-term health effects of PFAS exposure through breast milk.
It is essential to continue studying milk forever chemicals in mothers to inform public health policies and regulations. Further investigation is needed to understand the pathways of PFAS exposure and to identify strategies to reduce exposure levels. Additionally, more research is needed to understand the long-term health effects of PFAS exposure through breast milk and to develop effective interventions to protect mothers and infants’ health.
In conclusion, understanding the impact of forever chemicals in milk is crucial for protecting the health of mothers and infants. Continued research is needed to identify effective interventions and inform public health policies to reduce PFAS exposure levels and protect the most vulnerable populations.
