Are oxalates actually bad for You?
There’s No Need to Fear Oxalates. While some people may need to avoid dietary oxalates, particularly in large amounts, the evidence of their potential adverse effects on health is inconclusive. And for most people, many of the foods that contain oxalates are beneficial as part of a healthy, balanced diet.
How dangerous are oxalates?
Oxalates can form sharp, knife-like crystals in the body. These crystals can lodge in tissues and organs, causing pain and inflammation. Most people can handle low to moderate amounts of oxalate accumulation in the body. But problems like kidney stones develop when there are excessively high levels of oxalates.
Are oxalates to blame for inflammation in your body?

Why are oxalates bad?
- When you consume oxalates, you may get an adverse reaction because oxalates bind together with calcium, iron and other minerals
- Too many oxalates prevent calcium from being absorbed into the body [ii]
- Combining oxalates with eating fiber can also hinder absorption of minerals [iii]

The terms “oxalic acid” and “oxalate” are used interchangeably in nutrition science. Your body can produce oxalate on its own or obtain it from food.
Where does vitamin C convert to oxalate?
Vitamin C can also be converted into oxalate when it’s metabolized ( 2. Trusted Source. ). Once consumed, oxalate can bind to minerals to form compounds, including calcium oxalate and iron oxalate. This mostly occurs in the colon, but can also take place in the kidneys and other parts of the urinary tract.
Is oxalate a restriction for kidney stones?
Trusted Source. ). However, across-the-board oxalate restriction is no longer recommended to every person with kidney stones. This is because most of the oxalate found in urine is produced by the body, rather than absorbed from food ( 7.
How do oxalates work?
They work by decreasing the good bacteria that absorb oxalates and making the gut activity better. Your Gut and Oxalate Absorption. Sometimes the bacteria in your gut break down the oxalates you eat before they attach to minerals. One bacterium type, Oxalobacter formigenes, relies on oxalates as a source of energy.
What is the nutrient in leafy greens?

The process happens in the colon most of the time and sometimes in the kidneys. The body then removes the elements through stool or urine.
What bacteria absorbs oxalates?
One bacterium type, Oxalobacter formigenes, relies on oxalates as a source of energy. When it takes in the oxalate particles, it reduces the amount that your body absorbs. For people without high levels of this bacterium in the gut, the breakdown of oxalates is sometimes not effective. Antibiotics fight these bacteria colonies in the gut.
What happens when kidney stones join?

Oxalates are small nanoparticles that may be made in the body or may come from many healthy foods. These small particles are composed of 2 carbons and 4 oxygen molecules creating a supercharged particle. As a result of being “supercharged”, oxalates are known to bind with many other positively charged minerals.
Health Conditions Associated with Oxalates
Many different health conditions may be influenced by accumulation of oxalates. Often these foods are considered healthy. Due to this, many patients may overdo the oxalates in their attempts to eat healthier. The oxalates in higher amounts form crystals which may contribute to inflammatory conditions.

Conclusion
Paying attention to oxalates in foods is important in relationship to many inflammatory conditions. Since these foods are generally healthy, learning how to decrease oxalates is important to prevent issues. Learning how to optimize your diet and improve and decrease inflammation is important for most all health conditions.
