While anecdotal stories of bone broth's healing powers are common, credible medical institutions offer a more balanced perspective. This article explores what does Mayo Clinic say about bone broth, clarifying the science behind the hype and providing expert-backed insights on its nutritional value and health claims.

Quick Summary

A review of Mayo Clinic expert commentary on bone broth, revealing that while it is a nutritious and hydrating food, evidence supporting miraculous health claims like curing diseases is insufficient. The article examines its nutritional content, collagen absorption, and potential benefits for gut health and overall diet.

Key Points

Expert Skepticism: Mayo Clinic gastroenterologists caution against viewing bone broth as a 'miraculous cure' due to limited human research on specific benefits.
Nutrient-Dense Food: Bone broth is a good source of protein, amino acids, and minerals, making it a healthy addition to a balanced diet.
Collagen Processing: The body breaks down collagen from bone broth into amino acids, which it then uses for various protein synthesis needs, not necessarily targeting advertised areas.
Watch the Sodium: Commercially prepared bone broths can be very high in sodium; opting for low-sodium versions or homemade broth is recommended.
Use as a Supplement, Not a Cure: It is best used as a supplement to a healthy diet for hydration and protein, rather than a single solution for complex health issues.
Collagen vs. Stock: The longer simmer time of bone broth results in higher collagen and mineral content compared to standard stock.

Demystifying Bone Broth: What It Is and Its Nutritional Composition

Bone broth is a liquid derived from simmering animal bones, joints, and connective tissue for an extended period, often 12 to 72 hours. This lengthy cooking time, facilitated by an acidic element like vinegar, is intended to extract nutrients and minerals into the liquid, resulting in a rich, flavorful broth that often gels when chilled due to its high gelatin content. Its popularity has soared in recent years, particularly within paleo and keto dietary circles, with many crediting it for a host of health benefits.

At its core, bone broth is a source of protein and several minerals. While the exact nutritional profile varies significantly based on the bones used and cooking time, a typical serving provides a decent amount of protein, amino acids, and electrolytes.

Protein and Amino Acids: Bone broth is a notable source of protein, especially collagen, which breaks down into gelatin and important amino acids like glycine, proline, and glutamine.
Minerals: Electrolytes such as sodium, potassium, calcium, and magnesium are also present, though often in smaller quantities than popularly believed.
Hydration: Given its high water content, drinking bone broth can contribute to overall hydration, especially post-workout.

What Does Mayo Clinic Say About Bone Broth's Health Claims?

When evaluating the health claims surrounding bone broth, Mayo Clinic experts emphasize a measured, science-based approach, distinguishing it from popular miracle cures. While acknowledging its potential as a nutritious dietary component, they offer important context regarding its purported benefits for gut health, joint pain, and collagen.

Gut Health and Inflammation

Dr. Michael Camilleri, a gastroenterologist at the Mayo Clinic, has provided insight into the link between bone broth and gut health. He notes that bone broth is a source of the amino acid glutamine, which has been studied in animals and small human trials for its ability to reduce gut inflammation. However, Dr. Camilleri clarifies that while it's plausible that bone broth could support gut health, there is no conclusive human evidence to label it a 'miraculous cure' for gastrointestinal issues. Animal studies suggest anti-inflammatory properties, but these effects have yet to be proven in human subjects.

Collagen, Joints, and Skin

Bone broth is celebrated for its collagen content, which breaks down into gelatin during the simmering process. The belief is that consuming this collagen directly benefits joint health, skin elasticity, and other tissues. However, the Mayo Clinic Health System has addressed this directly, explaining that when the body ingests collagen, it is broken down into its component amino acids during digestion. The body then uses these amino acids to build new proteins where it is needed most, not necessarily where a supplement manufacturer claims it will go. Therefore, there's no guarantee that consuming bone broth will boost collagen levels in a way that specifically targets joints or skin. As one expert notes, there is "no downside to ingesting collagen, but there's also no clear benefit". A balanced diet rich in protein, including sources like bone broth, is key for overall protein needs and supporting the body's natural collagen production.

Weight Management and Other Benefits

Some claims suggest bone broth can aid in weight loss. As a low-calorie, high-protein liquid, it can indeed promote satiety and keep you full, but Mayo Clinic experts emphasize it should complement a balanced diet, not replace whole foods. Drinking a cup before a meal may help reduce overall intake, but it's not a standalone solution for weight management.

Potential Risks and Considerations

Despite its benefits, there are important considerations when consuming bone broth:

High Sodium Content: Many commercially prepared bone broths are high in sodium. Excessive sodium intake is a risk factor for high blood pressure and other heart conditions. The Mayo Clinic recommends choosing low-sodium or unsalted varieties or making your own to control the salt.
Heavy Metals: Some studies have raised concerns about heavy metals, such as lead, potentially leeching from bones into the broth during the long cooking process. To minimize risk, moderation is advised.
Not a Cure-All: The biggest risk lies in the misconception that bone broth is a cure-all. Relying solely on bone broth for complex health issues or inflammation may cause you to overlook more effective, evidence-based treatments.

Comparison of Bone Broth and Stock

To better understand the product, it's helpful to compare bone broth to traditional stock. The primary differences lie in the cooking time and ingredients used, which affect the final nutrient profile and texture.


Feature	Bone Broth	Stock
Primary Ingredients	Animal bones (often roasted), joints, cartilage, and an acidic agent (vinegar).	Meat, some bones, and aromatic vegetables.
Simmering Time	Very long, typically 12 to 72 hours, to extract minerals and collagen.	Much shorter, usually 2 to 3 hours.
Gelatin Content	High; produces a thick, gelatinous texture when refrigerated, indicating high collagen extraction.	Lower; does not typically gel when refrigerated.
Nutrient Density	Higher in protein (collagen) and minerals due to longer cooking time.	Lower nutrient density, primarily used for flavor.

Conclusion

In summary, what does Mayo Clinic say about bone broth? Their stance is one of cautious optimism, grounded in scientific evidence. While bone broth is a nutritious and hydrating addition to a healthy diet, rich in protein and amino acids, it is not a miracle cure for specific ailments. The scientific evidence for its grander health claims, particularly regarding direct collagen absorption and specific gut healing, is currently limited. Experts recommend incorporating it as part of a balanced nutritional plan, being mindful of potential high sodium content, and not viewing it as a substitute for professional medical advice or a diverse, whole-foods diet. Consult a healthcare provider or registered dietitian before making significant dietary changes, especially for pre-existing conditions.
