The Dish: Traditional Rice Porridge (Congee)

In many Asian countries, rice porridge — also known as congee — is a beloved, comforting dish. It's typically made from rice and water or broth, resulting in a soft, easy-to-digest meal that people of all ages enjoy. Due to its simple ingredients, it’s often recommended for people recovering from illnesses or surgeries, as it is gentle on the stomach.

Rich in carbohydrates and often served with a variety of toppings (such as pickled vegetables, meats, or even century eggs), congee is a popular choice for breakfast, lunch, or dinner. It’s also seen as an effective remedy for cold and flu symptoms in many cultures.

The Hidden Danger: High Oxalate Content for Kidney Stones Sufferers

Despite its reputation for being easy on the stomach, rice porridge can pose significant risks for those who suffer from kidney stones, especially if consumed frequently. Kidney stones form when minerals in the urine crystallize and form hard deposits. A major contributor to this process is the presence of oxalates — naturally occurring compounds found in many foods.

Rice, particularly white rice, contains high amounts of oxalates, which can increase the risk of calcium oxalate kidney stones. When a person with kidney stone issues eats foods high in oxalates, such as rice porridge, it can exacerbate their condition. The oxalates bind with calcium in the kidneys, leading to the formation of painful stones.

Why Kidney Stones Are More Likely with This Dish

The main reason rice porridge becomes problematic for those with kidney stones is its high oxalate content. Oxalates are also present in many other foods, such as spinach, sweet potatoes, and nuts. But rice, when eaten in large quantities, can significantly increase the level of oxalates in the body. Since congee is often consumed in large portions and as a frequent meal, its repeated consumption can contribute to the development or worsening of kidney stones.

How to Enjoy Rice Porridge Safely

While kidney stone sufferers should be cautious, they don’t have to avoid rice porridge entirely. Here are a few tips on how to enjoy it more safely:

1. Limit the portion size: Smaller servings of rice porridge can help reduce the amount of oxalates consumed at one time.

2. Balance with low-oxalate foods: Pair congee with toppings that are low in oxalates, such as lean meats or vegetables like cucumbers.

3. Consider brown rice: Brown rice has a slightly lower oxalate content than white rice, making it a safer alternative for those concerned about kidney stones.

4. Stay hydrated: Drink plenty of water throughout the day to help flush out oxalates from the kidneys and reduce the risk of stones.
