Is Breast Milk Safe for Adults to Drink? Uncovering the Health Risks and Myths

3 min read

According to a 2015 study, 93% of human breast milk samples purchased online contained detectable bacteria, underscoring significant safety risks. While human milk is biologically perfect for infants, many wonder if breast milk is safe for adults to drink, a practice with far more dangers than scientifically proven benefits.

Quick Summary

Consuming human breast milk as an adult is not recommended due to significant health risks, including exposure to infectious diseases and bacterial contamination. The nutritional profile is tailored specifically for infants, and there are no proven health benefits for adults that justify the dangers of unregulated sourcing.

Key Points

  • Significant Health Risks: Unregulated human milk can carry infectious diseases like HIV, Hepatitis, and bacteria, posing a serious threat to adults.

  • No Proven Adult Benefits: Claims of athletic enhancement, immune boosting, or curing illness in adults are not scientifically supported and are mostly anecdotal.

  • Nutritional Mismatch: Human milk's nutritional profile, including lower protein content, is designed specifically for infants and does not provide an adequate balance for adult dietary needs.

  • Unsafe Sourcing: Acquiring human milk from online marketplaces is extremely risky, with a high probability of bacterial contamination and improper handling.

  • Safety vs. Risk: Regulated milk banks ensure safety through screening and pasteurization, but their milk is reserved for vulnerable infants, not adult consumers.

  • Better Alternatives: Adults can meet their nutritional requirements safely and effectively through a balanced, diverse diet and regulated milk products.

The Fundamental Purpose of Breast Milk

Human breast milk is a complex, dynamic fluid perfectly tailored by nature to meet the rapidly changing developmental needs of a growing infant. Its composition is not static, evolving through stages like colostrum and mature milk, and even varying within a single feeding session. These differences reflect the specific needs of an infant’s immature digestive and immune systems, which are vastly different from an adult’s.

The Nutritional Mismatch for Adults

For an adult, the nutritional profile of human milk is simply inadequate. Mature human milk contains approximately 60-75 calories per 100ml, with around 1.2g/dL of protein, 3.6g/dL of fat, and 7.4g/dL of carbohydrates. An adult’s dietary needs for muscle maintenance, bone health, and overall bodily function require a different balance of macronutrients and a significantly higher volume, which a single mother could not produce.

The Significant Health Risks of Unscreened Human Milk

One of the most critical reasons why adults should not drink human milk from unofficial sources is the immense risk of contracting infectious diseases. Human breast milk is a bodily fluid and, like blood, can be a vector for pathogens. A 2015 editorial in the Journal of the Royal Society of Medicine warned that buying milk online exposes consumers to dangerous diseases, and studies have confirmed high levels of bacterial contamination.

Potential Infectious Disease Transmission

  • Human Immunodeficiency Virus (HIV): The risk of HIV transmission through breastfeeding is well-documented, making it a critical consideration for any unregulated human milk consumption.
  • Hepatitis B and C: These viruses can be passed through infected bodily fluids, including breast milk.
  • Cytomegalovirus (CMV): A common herpes virus that can be transmitted via breast milk and can cause serious complications in immunocompromised individuals.
  • Bacteria and Other Contaminants: Beyond viruses, milk purchased through informal channels often contains bacteria like Staphylococcus and Streptococcus, along with potential contaminants from improper handling, storage, and transport.

Donor Milk Banks vs. Online Sales: A Critical Distinction

It is crucial to understand the difference between acquiring human milk from a regulated milk bank versus purchasing it from an online marketplace. Reputable human milk banks have strict screening and pasteurization protocols to ensure donor milk is safe for vulnerable infants. Conversely, online sellers operate in an unregulated environment with no quality control.

Comparison: Human Milk Sourcing for Adults

Feature Online Marketplaces Regulated Milk Banks
Safety Screening Non-existent, relies on seller self-report. Donors undergo rigorous health screening, similar to blood donation.
Processing Untreated raw milk, high risk of bacterial contamination. Donated milk is pasteurized to inactivate potential viruses and bacteria.
Availability for Adults Readily available to anyone with payment. Not for adult consumption; milk is allocated to vulnerable infants with a prescription.
Risk Profile Extremely high risk of disease transmission and contamination. Very low risk due to stringent safety protocols.

Dispelling the Myths: Why Breast Milk Isn't an Adult Superfood

Despite anecdotal claims found in online forums, there is no robust scientific evidence to suggest that human milk offers specific health benefits for adults. Claims of immune-boosting properties or athletic enhancement are based on misunderstandings of how the nutrients and immune factors function. For example, while breast milk contains protective antibodies for infants, an adult's more developed immune system and digestive tract would break down most of these factors before they could have a significant effect. The potential benefits are far outweighed by the significant health risks associated with unregulated sources.

Conclusion: Prioritizing Safety and Proven Nutrition

While the practice of adults drinking human milk has historical roots, modern science and health organizations do not recommend it. The risks of consuming unregulated, potentially contaminated milk from online sellers are severe, including exposure to serious infectious diseases. Claims of health benefits for adults are unsubstantiated and lack scientific rigor, especially since the nutritional composition is optimized for infants, not grown individuals. For those seeking genuine health and wellness, a balanced diet of safe, proven food sources remains the safest and most effective path. Instead of buying milk online, consider donating surplus human milk to a milk bank to help a vulnerable infant in need. For more information on the risks of unregulated human milk, a study from the Journal of the Royal Society of Medicine offers a detailed analysis.

Frequently Asked Questions

The only safe scenario for an adult to consume human breast milk is if it comes directly from a known, trusted source, like a partner, and you are both aware of and accept the associated risks. Consuming milk from unregulated online sources is highly unsafe due to contamination risks.

No, this is a common myth. While human milk contains immune-boosting components like antibodies for infants, an adult's digestive system and more mature immune system render these largely ineffective when consumed orally.

Online-sourced breast milk is unregulated, meaning it is not screened for diseases or tested for contamination. Studies have shown high levels of bacteria in milk sold online, and there is a risk of transmitting infectious diseases such as HIV, Hepatitis, and syphilis.

Cow's milk is nutritionally different, containing higher protein levels and a different ratio of macronutrients better suited for adults than human milk. It is also pasteurized and regulated for safety, unlike human milk from informal sellers.

No, there is no scientific evidence to support claims that breast milk enhances athletic performance or muscle growth in adults. In fact, it has less protein than cow's milk and poses serious health risks when sourced improperly.

Despite anecdotal and historical claims, there is no robust scientific evidence that breast milk can effectively treat or prevent diseases like cancer or immune disorders in adults. Any perceived effects are likely a placebo.

The legality varies depending on location, but in many places, it is unregulated. The lack of regulation is precisely why purchasing milk online is so hazardous. Reputable milk banks are licensed and operate under strict guidelines.
