The bone broth diet has garnered significant attention for its purported weight-loss and gut-healing properties. However, focusing solely on the benefits ignores the potential risks and negative health impacts that some individuals may experience. Acknowledging these drawbacks is crucial for making an informed decision about this restrictive eating plan.
Navigating Potential Risks and Discomfort on a Bone Broth Diet
Digestive Upset: The Gut-Healing Paradox
While proponents suggest bone broth is soothing for the digestive tract, some individuals experience the opposite effect. Some users report gastrointestinal issues such as bloating, gas, nausea, constipation, or diarrhea. Research into a bone broth diet (BBD) found that a minority of participants reported mild, temporary digestive issues like diarrhea and constipation. For those with pre-existing conditions like irritable bowel syndrome (IBS) or leaky gut, certain components in the broth or the restrictive nature of the diet may exacerbate symptoms.
Sensitivity to Histamine and Glutamate
Bone broth, particularly when simmered for extended periods (24-48 hours), can become a high-histamine food. For individuals with histamine intolerance, this can trigger a range of adverse reactions, including headaches, rapid heart rate, brain fog, fatigue, and skin issues like rashes or hives. Similarly, the long cooking process can lead to high levels of glutamic acid. People with glutamate sensitivity may experience neurological symptoms such as anxiety, restlessness, mental exhaustion, or headaches.
Potential for Heavy Metal Contamination
There have been historical concerns regarding the potential for lead and other heavy metals to leach from animal bones into the broth during the long simmering process. Some studies have shown elevated lead levels in broth. While subsequent research suggests the risk might be minimal, especially with high-quality, properly sourced bones, the findings are not entirely conclusive and depend on the source and preparation method. The risk of heavy metal toxicity, however small, can be a valid concern for individuals following the diet long-term or consuming large amounts.
Concerns Over High Sodium Content
Many commercially prepared bone broths contain significant amounts of sodium to enhance flavor. A single cup can contribute a substantial portion of the recommended daily intake. Excessive sodium consumption poses a health risk, especially for individuals with high blood pressure, heart disease, or kidney disease. While choosing low-sodium or unsalted varieties or making homemade broth can mitigate this risk, it is a critical consideration for those with salt-sensitive health conditions.
The Threat of Nutritional Deficiencies
The bone broth diet is restrictive, often incorporating intermittent fasting or severely limiting whole food groups. This can lead to nutritional deficiencies over time, as essential nutrients found in grains, legumes, dairy, and fiber-rich vegetables are excluded. The low-calorie and low-carbohydrate nature can also cause side effects like fatigue and nausea, particularly during the adjustment phase.
Dangers of Intermittent Fasting and Yo-Yo Dieting
Many bone broth diet plans include intermittent fasting, with extremely low-calorie fast days. This approach is not suitable for everyone and poses significant risks for pregnant or nursing women, individuals with diabetes, or a history of disordered eating. The restrictive nature and potential for temporary weight loss can also lead to a cycle of yo-yo dieting, which is damaging to metabolism and long-term health.
Risks Associated with Commercial Bone Broth and Preparation
Beyond what the bones contain, the product itself can be problematic. Many commercial bone broths are misrepresented, containing fillers, high sodium, or artificial flavors. To avoid bacterial contamination, homemade broth requires strict adherence to food safety protocols regarding preparation and storage. Furthermore, the amino acids and minerals in bone broth can potentially interact with certain medications, such as blood thinners.
Bone Broth Diet Risks vs. A Standard Balanced Diet: A Comparison
| Feature | Bone Broth Diet | Standard Balanced Diet |
|---|---|---|
| Nutrient Intake | Risk of deficiencies in fiber, calcium, and carbohydrates due to food group restrictions. | Offers a wider range of nutrients from a variety of food sources, reducing deficiency risks. |
| Digestive Impact | Potential for digestive upset (bloating, gas, etc.) in sensitive individuals, despite purported benefits. | Generally supports digestive health with adequate fiber and hydration, though individual sensitivities can vary. |
| Histamine & Glutamate | Higher histamine content from long simmering times may trigger intolerance symptoms in sensitive people. | Typically lower in histamines, unless high-histamine foods are consumed in large quantities. |
| Heavy Metals | Risk of lead leaching from animal bones, though research findings are mixed. | Not a concern, as diet does not rely on boiling animal bones for extended periods. |
| Sodium Control | High sodium is a common issue with commercial products, posing risks for specific health conditions. | Offers more control over sodium intake through whole food choices and preparation methods. |
| Long-Term Sustainability | Often a short-term, unsustainable diet plan that can lead to yo-yo dieting. | Emphasizes long-term, sustainable eating habits for consistent health and wellness. |
Conclusion: Weighing the Risks and Benefits
While the bone broth diet may offer some perceived benefits, the potential for significant side effects and health risks cannot be overlooked. Digestive issues, sensitivities to histamines and glutamate, and concerns over heavy metal contamination and high sodium are all valid considerations. Furthermore, the diet's restrictive nature may lead to nutritional deficiencies and unsustainable weight loss patterns. For many, a balanced and varied diet is a safer, more sustainable path to health. Anyone considering a bone broth diet, especially those with pre-existing health conditions, should consult with a healthcare provider or a registered dietitian first.

Frequently Asked Questions
Q: What digestive issues can a bone broth diet cause? A: Some people experience digestive issues like bloating, gas, constipation, and nausea, which can be due to sensitivities to the fat or other components in the broth.
Q: Can bone broth cause headaches? A: Yes, headaches can be a side effect, particularly in individuals with histamine intolerance, as long-simmered bone broth is a high-histamine food. Sensitivity to glutamate is another potential cause.
Q: Is there a risk of lead poisoning from bone broth? A: While earlier studies raised concerns about lead leaching from bones, more recent research suggests the lead content is likely low, especially with high-quality sources. However, the risk is not entirely dismissed, and the source of the bones matters.
Q: Is the bone broth diet high in sodium? A: Many commercial bone broths are high in sodium. For individuals with high blood pressure, heart disease, or kidney disease, this can be a serious health risk. Choosing low-sodium options or making homemade broth is a safer choice.
Q: Who should not go on a bone broth diet? A: The diet is not recommended for pregnant or nursing women, individuals with diabetes, kidney or liver disease, those with a history of disordered eating, or vegetarians and vegans.
Q: Does bone broth break a fast? A: Yes, because bone broth contains calories, it will break a fast if the goal is autophagy. For other forms of intermittent fasting (where some calories are allowed), it may or may not be permitted depending on the specific protocol.
Q: How do you know if you have histamine or glutamate sensitivity? A: If you consistently experience symptoms such as headaches, brain fog, fatigue, or skin rashes after consuming bone broth or other high-histamine/glutamate foods, you may have a sensitivity. Consulting a healthcare provider for proper diagnosis is recommended.
