When we think of vegetables, we often picture vibrant salads, green smoothies, and other staples of a “healthy diet.” But what if some of these beloved greens are doing more harm than good? This controversial topic has gained attention thanks to the work of Sally K. Norton, who has brought the potential dangers of oxalates to light. Let’s dive into what oxalates are, why they may be harmful, and how to recognize if they’re causing issues for you.

Key notes
What Are Oxalates?
Oxalates, or oxalic acid, are naturally occurring compounds found in many plants. They serve a protective function for the plants, deterring pests and predators. For humans, however, these compounds can sometimes do more harm than good.
Oxalates bind to minerals like calcium and magnesium in the body to form crystals, which can accumulate and cause various health issues. While the body does produce a small amount of oxalates naturally, the majority comes from our diet.
Which Foods Are High in Oxalates?
Oxalates are present in a wide range of plant-based foods, including some that are considered exceptionally healthy. Here are some common culprits:
- Leafy greens: Spinach, Swiss chard, and beet greens are particularly high in oxalates.
- Nuts and seeds: Almonds, cashews, and chia seeds.
- Fruits: Rhubarb, starfruit, and figs.
- Vegetables: Beets, sweet potatoes, and okra.
- Other plant foods: Dark chocolate, soy products, and certain grains like quinoa.
While eating these foods in moderation may not pose a problem for everyone, excessive consumption can lead to an overload of oxalates in the body.
How Do Oxalates Harm the Body?
When oxalates bind to calcium or other minerals, they form crystals that can deposit in various tissues and organs. This can lead to a range of health issues, including:
- Kidney Stones: One of the most well-known effects of oxalates is their role in kidney stone formation. Oxalate crystals can accumulate in the kidneys, leading to pain, inflammation, and urinary complications.
- Joint Pain and Inflammation: Oxalate crystals can deposit in the joints, mimicking conditions like arthritis and causing pain and stiffness.
- Gut Health Issues: High levels of oxalates can irritate the gut lining and disrupt the microbiome, potentially leading to digestive discomfort and nutrient malabsorption.
- Mineral Deficiencies: By binding to calcium, magnesium, and other vital minerals, oxalates can reduce the body’s ability to absorb these nutrients, contributing to deficiencies over time.
- Tissue Damage: Oxalates can accumulate in tissues like the thyroid gland, skin, and even the eyes, potentially leading to systemic inflammation and other chronic symptoms.
Symptoms of Oxalate Overload
If your body is struggling to handle oxalates, you might experience a variety of symptoms that could be mistaken for other conditions. Common signs of oxalate overload include:
- Recurrent kidney stones
- Chronic joint pain or stiffness
- Persistent fatigue
- Digestive issues, such as bloating or diarrhea
- Burning sensations during urination
- Skin rashes or irritation
- Muscle pain or weakness
It’s important to note that symptoms can vary widely depending on where oxalate crystals are depositing in the body.
Sally K. Norton’s Contribution to the Discussion
Sally K. Norton, a leading expert on oxalates, has dedicated years of research to uncovering the hidden dangers of these compounds. In her work, she highlights how modern diets—often praised for being plant-heavy—can inadvertently lead to an overload of oxalates.
Norton emphasizes that even so-called “superfoods,” like spinach and almonds, can contribute to health issues if consumed in large amounts. Her findings encourage a more mindful approach to plant-based eating, advocating for balance and awareness rather than blindly following dietary trends.

What Can You Do About Oxalates?
If you suspect that oxalates are causing health issues for you, here are some steps you can take:
- Limit High-Oxalate Foods: Reduce your intake of foods particularly high in oxalates, such as spinach, almonds, and beets. Focus instead on low-oxalate options like cucumbers, zucchini, and animal-based proteins.
- Increase Calcium Intake: Consuming calcium-rich foods like dairy products or calcium supplements during meals can help bind oxalates in the gut, preventing their absorption.
- Stay Hydrated: Drinking plenty of water can help flush oxalates out of your system and reduce the risk of kidney stone formation.
- Support Gut Health: A healthy gut microbiome can aid in breaking down oxalates. Probiotic-rich foods like yogurt, kefir, and sauerkraut may be beneficial.
- Work with a Professional: If you’re experiencing symptoms of oxalate overload, consider consulting a healthcare professional or nutritionist familiar with this issue. They can help guide you through dietary changes and identify any underlying health conditions.
Final Thoughts
While vegetables are often considered the cornerstone of a healthy diet, it’s worth remembering that not all “healthy” foods work well for every individual. Oxalates, found in many plant-based foods, can pose serious health risks when consumed in excess. Thanks to researchers like Sally K. Norton, we’re beginning to understand the nuanced relationship between oxalates and our well-being.
If you’re struggling with unexplained health issues, it might be worth exploring whether oxalates could be a contributing factor. By making informed choices and listening to your body, you can find a diet that truly supports your health and vitality.
