Is it healthy for adults to drink breast milk? The scientific facts

3 min read

According to a 2015 study, 93% of breast milk samples purchased online were contaminated with bacteria, highlighting significant health risks for adult consumers. This sheds light on the serious concerns surrounding the consumption of breast milk by adults, a practice that lacks proven health benefits for adults despite various online claims.

Quick Summary

Despite its nutritional benefits for infants, human breast milk offers minimal, if any, validated health advantages for adults. Potential risks, especially from unregulated sources, include serious infectious diseases and bacterial contamination. Professional health organizations do not recommend adult consumption.

Key Points

  • Limited Benefit: Scientific evidence does not support claims that breast milk offers significant health benefits for healthy adults.

  • High Risk from Unregulated Sources: Obtaining breast milk from online marketplaces carries serious risks of bacterial contamination and infectious diseases like HIV, Hepatitis, and Syphilis.

  • Digestive Differences: An adult's digestive system, with its higher acidity and reduced ability to digest lactose, is not optimized to absorb the benefits of human milk.

  • Nutritionally Inadequate: Compared to dairy or other milk alternatives for adults, breast milk is lower in protein and lacks the necessary balance of nutrients for adult health goals.

  • Ethical Concerns: Using breast milk for non-infant consumption raises ethical issues, especially when it diverts resources from regulated milk banks that serve vulnerable babies.

  • Expert Consensus: Health organizations and medical professionals do not recommend adult consumption of human breast milk due to unproven benefits and significant safety concerns.

  • Safer Alternatives Exist: For nutritional needs, a balanced diet and conventional food sources are safer and more effective for adults.

Unpacking the Myths and Misconceptions

Claims that breast milk is a 'superfood' for adults have proliferated online, often fueled by anecdotes rather than scientific evidence. Proponents suggest it can boost the immune system, improve muscle mass, or even fight off certain diseases. However, medical experts and scientific research largely debunk these assertions, stressing that breast milk is biologically tailored for infants, not mature adults. An adult's digestive system is fundamentally different from a baby's, meaning many of the beneficial components found in human milk are less effective or simply broken down before they can be absorbed.

The Lack of Proven Health Benefits for Adults

While breast milk is undeniably nutritious for babies, its nutritional profile is optimized for infant growth and development. For adults, these benefits do not translate directly.

  • Protein Content: Breast milk contains less protein than cow's milk, making it a poor choice for adults seeking to build muscle mass.
  • Immune Factors: The antibodies and immune factors present are most effective in an infant's developing gut. An adult's higher stomach acidity often degrades these components, rendering them ineffective.
  • Digestive Differences: Breast milk is high in lactose. Many adults lose the ability to digest lactose, potentially causing discomfort.
  • Hormonal Effects: Growth hormones in breast milk do not show evidence of benefiting adults.

The Serious Risks of Unregulated Breast Milk

Obtaining breast milk from informal, unregulated sources, such as online marketplaces, is a significant concern. This practice carries serious health risks due to lack of screening and safety protocols. Unregulated sources lack pasteurization and screening for infectious diseases like HIV, syphilis, or hepatitis, which can be transmitted through breast milk.

Comparison of Human Milk Sources

Feature Online Marketplace Milk Regulated Milk Bank Milk Trusted Partner Milk Cow's Milk (for Adults)
Safety Screening None Rigorous Dependent on partner's health Subject to regulations
Pasteurization Unpasteurized Pasteurized Unpasteurized Pasteurized
Risk of Infectious Diseases High (HIV, Hepatitis) Very low Dependent on partner's health Very low
Risk of Bacterial Contamination High (study found 93%) Very low Medium (if improperly stored) Very low
Nutritional Appropriateness Not optimized for adults Designed for infants Not optimized for adults Tailored for adult needs

Addressing the Ethical Implications

Beyond health concerns, the adult market for human breast milk raises ethical questions. Breast milk is a valuable resource specifically intended for infants, especially those who are vulnerable. Diverting this resource to adults, who have access to numerous other nutrient-rich foods, can be viewed as inappropriate.

Expert Consensus and Recommendations

Health organizations and medical experts agree: there are no proven health benefits for healthy adults drinking human breast milk, and it comes with considerable risks, particularly if the source is unregulated. A balanced diet from conventional food sources is the safest and most effective option for adults.

Conclusion: A Cautionary Note

While drinking breast milk for health benefits may be a trendy topic, scientific evidence doesn't support this for adults. The risks of contamination from unverified sources and lack of demonstrable benefits make it ill-advised. For those seeking health improvements, a diverse diet, exercise, and professional medical advice are recommended. For those with surplus breast milk, donation to a regulated milk bank serves a critical need for vulnerable infants.

The Risks of Unregulated Breast Milk

Obtaining milk from unregulated online vendors is a major risk. These platforms lack screening and pasteurization, leading to a high potential for contamination. Donors may carry infectious diseases transferable through milk. A study found nearly all samples from online sources had bacterial contamination. Medical professionals strongly discourage consuming human milk bought online. For more information, the 2015 study in the Journal of the Royal Society of Medicine, "More than a lucrative liquid: the risks for adult consumers of human breast milk bought from the online market," is a valuable resource.

Nutritional Inadequacies for Adult Needs

For adults, human milk is a poor nutritional choice. It contains a different balance of nutrients than what adults need, particularly lacking in protein relative to cow's milk. While perfect for infants, its composition isn't designed for an adult digestive system. Many components are broken down during adult digestion, offering little to no benefit. For muscle building or overall adult health, nutrient-dense foods and conventional milks provide more appropriate nutrition with lower risk.

Frequently Asked Questions

No, despite popular claims, there are no scientifically proven health benefits for healthy adults who drink breast milk. The nutritional composition is specifically designed for infants and does not offer superior advantages over a balanced adult diet.

No, it is highly unsafe to buy human breast milk from unregulated online sources. Studies have shown a high rate of bacterial contamination and a risk of infectious diseases, as the milk is not screened or pasteurized.

Drinking unpasteurized breast milk from an untested source can expose adults to various pathogens, including bacteria (like Salmonella or Streptococcus) and viruses (like HIV, Hepatitis B and C, and Syphilis).

No, breast milk contains less protein than cow's milk and is not an efficient source for adult muscle building. Claims of athletic gains are not supported by scientific evidence.

While less risky than buying online, it is still not medically recommended. A partner's milk could contain viruses or bacteria, even if they appear healthy. The primary risk is with the transfer of infectious diseases.

Breast milk is perfectly formulated for an infant's needs and underdeveloped digestive and immune systems. An adult's mature digestive system breaks down many of the unique components, rendering them ineffective, and adults have different nutritional requirements.

Instead of consuming or selling it, excess breast milk can be donated to a regulated human milk bank. These banks screen and pasteurize the milk, providing it safely to premature and medically fragile infants in need.
