Are Oranges High in Oxalates?

Oxalates are naturally occurring compounds found in a variety of foods, including fruits, vegetables, nuts, and seeds.

While they are generally harmless for most people, excessive oxalate consumption can lead to the formation of kidney stones in susceptible individuals.

This article will explore the oxalate content in oranges and provide recommendations for including them in an oxalate diet.

Are Oranges High in Oxalates?

Oranges have a high oxalate content, with a 100-gram serving containing approximately 1-3 milligrams of oxalates. Therefore, oranges should not be included in an oxalate diet in order to avoid any risk related to kidney stones.

Understanding Oxalates

Oxalates, or oxalic acid, are organic compounds that can bind to minerals in the body, such as calcium, forming crystals that may accumulate in the kidneys and lead to kidney stones.

For individuals who are prone to kidney stones or have been advised to follow a low-oxalate diet, it is important to be aware of the oxalate content in the foods they consume.

The Oxalate Diet

An oxalate diet involves limiting the intake of foods high in oxalates while increasing the consumption of low-oxalate foods.

This diet is often recommended for individuals with a history of kidney stones or other oxalate-related health issues.

The key principles of an oxalate diet include being aware of the oxalate content in foods, consuming calcium-rich foods to reduce oxalate absorption, and drinking plenty of water to help flush oxalates from the body.

Nutritional Benefits of Oranges


Oranges are a popular fruit known for their high vitamin C content.

They are also a good source of fiber, antioxidants, and several other vitamins and minerals, such as folate, potassium, and thiamine.

Including oranges in your diet can provide numerous health benefits, such as boosting immune function, promoting heart health, and reducing the risk of chronic diseases.

Oxalate Content in Oranges

Oranges have a high oxalate content. A 100-gram serving of oranges contains approximately 1-3 milligrams of oxalates.

This is significantly lower than the oxalate content in some other fruits, such as blackberries and kiwifruit, and vegetables like spinach and beet greens.

However, oranges can’t be included in an oxalate diet.

Managing oxalate intake is essential for individuals following an oxalate diet.

Here are some tips for reducing oxalate consumption:

  • Be aware of the oxalate content in the foods you consume.
  • Cook high-oxalate foods to reduce their oxalate content.
  • Consume calcium-rich foods along with high-oxalate foods to reduce oxalate absorption.
  • Drink plenty of water throughout the day to help flush out oxalates from the body.
