Navigating the Oxalate Maze on a Ketogenic Diet 🌱🔍

Navigating the Oxalate Maze on a Ketogenic Diet 🌱🔍

Embarking on a ketogenic journey promises transformational health benefits, from dramatic weight loss to improved mental clarity and beyond. This higher-fat, low-carb pathway to wellness has indeed revolutionised our approach to dieting and health. Yet, the road to ketosis is paved with nutritional nuances, one of which is the careful consideration of oxalates—a topic often overshadowed by the bright lights of ketones and carb counting.

Understanding Oxalates

Oxalates, or oxalic acid, are organic compounds found in a wide range of foods, from leafy greens to nuts and even chocolate. In nature, oxalates serve as a plant's protective shield against pests, but in the human body, they can be a double-edged sword. While typically excreted through urine, excessive intake of oxalates can lead to their accumulation, posing potential health risks. This is particularly relevant in the context of a ketogenic diet, where food choices may inadvertently skew towards higher oxalate levels, lets dive deeper into oxalate biology.

Risks of High Oxalate Consumption

Kidney Health

The most well-documented risk associated with excessive oxalate intake is the formation of kidney stones. Oxalates can bind with calcium in the urine to form calcium oxalate stones, leading to painful and sometimes serious health complications. For individuals on a ketogenic diet, a regimen that naturally emphasises the consumption of certain high-oxalate foods, this risk warrants attention. 

Bone Health

Beyond the kidneys, oxalates can also impact bone health. By binding with calcium, oxalates not only reduce the amount of calcium available for strengthening bones but can also lead to the formation of deposits in bone tissue, potentially weakening bones over time. For those adhering to a ketogenic lifestyle, understanding the balance between nutrient-rich foods and their oxalate content is key to maintaining bone health. 

Gut  So what foods are low in Oxalates ? Health

The impact of oxalates extends to gut health, where they can contribute to inflammation and a reduction in the gut's ability to absorb nutrients effectively. This is of particular concern on a ketogenic diet, where maximising nutrient absorption from food sources is crucial. 


So what foods are high in Oxalates ? 

  • Spinach: Often used in keto diets due to its low carb content but is very high in oxalates.
  • Almonds: A popular "snack" and almond flour is frequently used in keto recipes, both of which are high in oxalates.
  • Swiss Chard: Like spinach, it's a leafy green that's keto-friendly but also rich in oxalates.
  • Chocolate: Especially dark chocolate, which is considered more keto-friendly due to its lower sugar content, is high in oxalates.
  • Tea: Certain types, especially black and green teas.
  • Sesame Seeds: Often used in keto recipes, they are another source of oxalates.

So what foods are low in Oxalates ? 


  • Cauliflower: Versatile for cooking or raw eating, great for keto recipes.
  • Zucchini:  (thats the correct word for the plant by the way 😉)Perfect for noodles or as a side dish, very keto-friendly.
  • Asparagus: Excellent grilled, roasted, or steamed.
  • Broccoli: Ideal for stir-fries or as a side.
  • Cabbage: Great in salads or as a cooked side dish.
  • Lettuce: Various types are perfect for salads or wraps.
  • Radishes: Add a crunchy, spicy note to salads.

Fruits (Note: Fruits should be consumed in moderation on a ketogenic diet due to their natural sugar content)

  • Avocado: High in healthy oils, very low in carbs.
  • Olives: Great as a snack or added to dishes for extra fat.


  • Eggs: Highly versatile, a keto staple.
  • Beef: Choose grass-fed when possible for more omega-3 fats.
  • Poultry: Chicken, turkey, and other birds are excellent protein sources.
  • Pork: Look for uncured options to avoid added sugars.
  • Lamb: A good source of high-quality protein.
  • Fish: Particularly fatty fish like salmon, mackerel, and sardines, which are high in omega-3s.
  • Shellfish: Most are low in oxalates, but watch for carb content in some types.


  • Cheese: Hard and aged cheeses are generally lower in carbs.
  • Butter and Ghee: Excellent sources of fat for keto.
  • Heavy Cream: Great for coffee or recipes, but watch the portion size.

Nuts and Seeds

  • Macadamia Nuts: Low in carbs and oxalates, high in fats.
  • Pecans: Low in oxalates and suitable for keto.
  • Brazil Nuts: Selenium-rich and keto-friendly.
  • Hemp Seeds: Low in oxalates, high in omega-3s.

Fats and Oils

  • Olive Oil: Great for salads.
  • Avocado Oil: Also perfect for salads.
  • MCT Oil: Can help boost ketone production.


  • Water: Essential for hydration. (with electrolytes)
  • Bone Broth: Nutrient-rich and low in carbs.
  • Unsweetened Tea: Most herbal teas are low in oxalates.
  • Unsweetened Coffee: Enjoy in moderation.

Conclusion: Balancing Your Ketogenic Journey with Oxalate Awareness 🍽️💡

Embarking on a ketogenic diet can be a transformative journey towards better health, weight loss, and enhanced mental clarity. However, like any path to wellness, it comes with its set of challenges and considerations. Among these, the topic of oxalates stands out as a crucial but often overlooked aspect of dietary planning. As we've explored, while oxalates are naturally occurring compounds in many nutritious foods, their high intake poses risks to kidney health, bone density, and gut wellness, particularly for those on a ketogenic diet.

The journey does not end at awareness, though. It begins anew with the empowered choices we make at the shops to the kitchen, and as we plate our meals. By incorporating low-oxalate foods into your ketogenic diet, you can enjoy the vast benefits of ketosis while minimising potential health risks associated with high oxalate intake. Vegetables like cauliflower, zucchini, and asparagus; proteins such as eggs and most meats; and healthy fats are not only low in oxalates but also keto-friendly, ensuring you don't have to compromise on taste or variety.

Remember, the goal of a ketogenic diet is not just about adhering to strict rules but about finding a sustainable, enjoyable way to live healthier. Knowledge of oxalates adds another layer to this journey, allowing for a more nuanced approach to nutrition that supports your body's needs in every way.

As you continue on your ketogenic path, consider this guide not just as a cautionary tale but as a beacon, illuminating the way towards a balanced, informed approach to health and well-being. With the right knowledge and tools at your disposal, you're more than capable of navigating the oxalate maze, making choices that align with your health goals and dietary preferences.

Stay curious, stay informed, and above all, stay on the path that feels right for you. Here's to your health, happiness, and a successful ketogenic journey, with oxalate awareness in tow. Cheers to a vibrant, healthful life ahead! 🥂🌿
