Is it safe for an adult to drink breast milk? The health risks and benefits

3 min read

A 2015 study revealed that 93% of breast milk samples purchased online contained detectable bacteria, highlighting significant health risks for adult consumers. While human milk is a nutritionally complete food for infants, the question of whether it is safe for an adult to drink breast milk is far more complex and often misunderstood.

Quick Summary

Adult consumption of breast milk offers no scientifically proven health benefits and carries significant risks, especially from unpasteurized or unregulated sources. Potential dangers include bacterial contamination and transmission of infectious diseases like HIV, Hepatitis B, and Syphilis. For a healthy adult, the nutritional value is less than cow's milk, making it an unnecessary health risk.

Key Points

  • No Proven Adult Benefits: Breast milk offers no scientifically proven health advantages for healthy adults, despite anecdotal claims.

  • High Risk from Online Sources: Purchasing breast milk online from unregulated sellers poses a significant risk of bacterial contamination and infectious disease transmission.

  • Nutritional Discrepancy: The nutritional composition of human milk is tailored for infants, not adults, and contains less protein than cow's milk.

  • Adult Digestive System: An adult's digestive system breaks down the protective immune factors in breast milk, negating any potential benefits.

  • Infectious Disease Vector: Without proper screening and pasteurization, breast milk can transmit serious illnesses like HIV, hepatitis, and syphilis.

  • Safe Sourcing Alternatives: Reputable milk banks screen and pasteurize donor milk, but it is reserved for medically fragile infants, not for adult recreational use.

  • Risk of Adulteration: The unregulated nature of the online market means milk may be diluted or contaminated with other substances.

The Allure and Misconceptions Behind Adult Breast Milk Consumption

Over the years, various claims have surfaced about the supposed benefits of adult breast milk consumption, from boosting immunity and muscle growth to treating diseases like cancer. These claims often circulate on online forums and among niche communities, creating a demand that has led to a booming, unregulated online market for human milk. Despite these anecdotal accounts, scientific evidence robustly refutes the idea that breast milk is a 'superfood' for adults. The biological makeup of an adult's digestive system is fundamentally different from an infant's, meaning many of the protective and developmental factors in breast milk are broken down before they can provide any benefit.

Significant Health Risks of Unregulated Breast Milk

One of the most pressing concerns regarding adult consumption of breast milk is the source. The practice becomes extremely hazardous when purchasing milk from strangers online.

  • Bacterial Contamination: Studies have shown that a high percentage of breast milk purchased online is contaminated with bacteria due to improper handling, storage, and transport. Raw, unprocessed milk, whether human or animal, carries a risk of foodborne illness.
  • Infectious Disease Transmission: Breast milk is a bodily fluid and can be a vector for serious infectious diseases if the donor is unaware or dishonest about their health status. Risks include HIV, hepatitis B and C, syphilis, and cytomegalovirus (CMV). Regular, ongoing screening is necessary to ensure safety, which is not guaranteed with online sellers.
  • Cross-Contamination and Adulteration: The online market is completely unregulated, leading to a high risk of adulteration. Sellers have been known to dilute breast milk with cow's milk or even water to increase volume for sale. This poses additional health risks and a deceptive product for the consumer.

Debunking the Supposed Benefits for Adults

Many popular myths about adult breast milk consumption lack scientific backing. While breast milk does contain various bioactive components, their effect on the adult body is minimal compared to the targeted benefits for a developing infant.

  • Immune System Boost: Though breast milk contains antibodies and immune factors, a healthy adult already possesses a mature immune system. The protective components are largely destroyed by the adult digestive tract's high acidity before they can be effectively absorbed.
  • Muscle Growth and Bodybuilding: The protein content in human breast milk is significantly lower than in cow's milk and does not offer a particular advantage for muscle building. The idea that it is a 'superfood' for athletic performance is purely anecdotal and not supported by research.
  • Disease Treatment: Despite claims, there is no scientific evidence to support breast milk as a treatment or cure for serious conditions like cancer or immune disorders in adults. Any perceived relief for immunocompromised individuals is unvalidated and requires further study.

Comparison: Breast Milk vs. Cow's Milk for Adult Nutrition

To understand why breast milk offers no special advantage for adults, a comparison of its nutritional profile with commonly consumed cow's milk is insightful.

Nutritional Component Human Breast Milk (per 100g) Cow's Milk (per 100g) Why It Matters for Adults
Protein ~1.2g ~3.3g Cow's milk offers more protein for muscle repair and building, a common goal for adults seeking supplementary nutrition.
Fat ~4.0g ~3.9g (whole milk) Fat content is comparable, but breast milk fat varies widely within a single feeding and by diet.
Carbohydrates (Lactose) ~7.0g ~4.8g Breast milk has higher lactose, which many adults are lactose intolerant to, causing digestive issues.
Immune Factors High (Antibodies, Oligosaccharides) Minimal These components are tailored for infant immunity and are largely ineffective in the adult digestive system.

Conclusion

While the concept of adult breast milk consumption may seem intriguing, especially given the known benefits for infants, the scientific evidence does not support its use for adult health. The purported benefits are unsubstantiated, and the risks associated with sourcing unpasteurized milk from unregulated online markets are substantial and dangerous. Consuming breast milk from an untested source exposes an individual to potentially lethal infectious diseases and foodborne pathogens. For a healthy adult, safer and more effective nutritional options are widely available, providing superior nutritional value without the significant health risks. It is a misguided and unnecessary practice that should be strongly discouraged for anyone seeking to improve their health.

Frequently Asked Questions

Consuming breast milk from a known, trusted source (like a lactating partner) carries less risk than unregulated sources, but it still offers no proven health benefits for adults. The primary danger lies in buying milk online from strangers.

There is no scientific evidence to support this claim. An adult's digestive system and mature immune system render the antibodies and immune factors in breast milk largely ineffective for systemic health benefits.

While some anecdotal accounts exist, there is no solid research proving that consuming breast milk helps treat cancer or immune disorders in adults. The risks, particularly from unpasteurized milk, far outweigh any theoretical benefits.

Online-purchased breast milk is unregulated and unpasteurized. Studies show it is frequently contaminated with bacteria and can transmit serious infectious diseases from the donor, including HIV and hepatitis.

No. Breast milk is specifically formulated for infants and has a lower protein content than cow's milk. Cow's milk is a more suitable nutritional supplement for healthy adults.

Consuming contaminated breast milk can lead to foodborne illnesses from bacteria like Staphylococcus or Streptococcus, causing symptoms such as diarrhea, pneumonia, or more severe infections.

Some people use breast milk topically for minor skin issues, like diaper rash or eczema, but medical professionals advise caution. For serious conditions, consult a doctor, as unpasteurized milk could worsen an infection.
