Who Needs Low Oxalate Fruit?
Before we dive into the world of low oxalate fruit, it is important to understand who actually NEEDS low oxalate fruit in the first place.
The key to make sure a low oxalate diet will prevent kidney stones is a 24-hour urine test. This test will tell you and your doctor why your body is making kidney stones. Without it, it is a guess what will actually prevent stones for YOU! Kidney stone nutrition is different for everyone.
If your oxalate is high on a 24-hour urine test, you might need to cut back on how much oxalate you eat. Eating enough calcium is usually a more effective way to lower urine oxalate.
If you do not have high urine oxalate, you do not need a low oxalate diet. A low oxalate diet will likely not prevent kidney stones for you. You don’t need to worry about low oxalate fruit!
Kidney Stone Nutrition is A Lot More Than Oxalate
In fact, oxalate is the LEAST of my concerns for most of my patients with kidney stones. Yes, even if they have calcium oxalate kidney stones!
Depending on your 24-hour urine test results, there are many possible nutrition changes you could make to stop kidney stones. Here are some of the most common nutrition changes I recommend for kidney stone prevention:
- Drink more water!
- Watch how much sodium you eat. Most people should aim for about 2,300mg of sodium per day.
- Eat more dairy to help make sure you get enough calcium.
- Eat smaller portions of meat, chicken or fish.
- Push the produce! Eating more fruits and vegetables is one of the most effective ways to ward off kidney stones.
It is KEY to make sure your diet is personalized to your 24-hour urine test results. Otherwise, your diet changes may not be targeting your body chemistry, and not doing much to prevent kidney stones for YOU.

My Favorite Low Oxalate Fruits
Here are my favorite low oxalate fruits. See below for a more complete list of low oxalate fruit!
2mg oxalate per cup
A classic. Both red and green grapes are a great low oxalate fruit option.
Enjoy them plain. Or, get fancy and roast them to add to things like flatbreads, oatmeal or salads!
4mg oxalate per cup
Not all berries are high in oxalate. Blueberries are a great low oxalate fruit option. As a Michigan girl, I LOVE blueberries.
Check out this delicious Blueberry Cobbler recipe!
4mg oxalate per cup
What is better than biting into a juicy piece of pineapple? I love snacking on pineapple chunks. Try grilling pineapple slices to jazz up chicken sandwiches, pizza, salads and even an occasional cocktail! Pineapple is also a delicious addition to stir fry.
2mg oxalate per pear
I think pears may be one of the most underrated fruits out there. Pears are delicious!
Again, eat them raw. Or, roast them to add to sandwiches, salads, oatmeal, toast or flatbreads.
I also love this Maple Pear and Goat Cheese salad. Exciting salads like these are such a wonderful way to up your produce intake for kidney stone prevention. Note: This salad does have pecans on it, but not all nuts are high oxalate!
0-1mg oxalate per cup
Melon lovers rejoice! All varieties of melon are a great low oxalate fruit choice. Low oxalate melon includes:
- Honeydew Melon
Try my Watermelon Lime Sorbet as a delicious frozen summer treat!
1mg oxalate per apple
Yes! All varieties of apples are low oxalate. By themselves, apples are the perfectly portioned portable snack!
You can also bake apples into a tasty apple crumble, chop them into salads or use as a yogurt topping (sprinkled with a little cinnamon!).
I also love these dried apple slices*!
More Low Oxalate Fruit
I could go on and on with all of the delicious low oxalate fruit options out there. Here are some more of my favorites:

High Oxalate Fruit
If you need a low oxalate diet, there are few very high oxalate fruits that you need to limit.
Here are some very high oxalate fruits:
- Raspberries (48mg oxalate per cup)

- Canned or Dried Pineapple (24mg & 30mg oxalate per 1/2 cup, respectively)
That is it! Truly, all other fruits can fit in a healthy diet for kidney stones.
