Many people turn to natural remedies in order to prevent kidney stones from forming, and one such remedy is blueberries. But can consuming blueberries actually cause kidney stones? Let’s take a look.


Blueberries have long been known for their health benefits, with research showing that they are high in antioxidants, vitamins C and K, fiber, and various other nutrients. In recent years, some have suggested that eating too many blueberries could lead to the formation of kidney stones.

What Are Kidney Stones?

Before we delve into whether or not blueberries can cause kidney stones, let’s first understand what exactly these pesky little things are. Kidney stones are hard deposits of salt and other minerals that form inside your kidneys. They can range in size from tiny grains of sand to large golf balls (ouch!) and can cause intense pain when passing through the urinary tract.

Symptoms of kidney stones include severe pain on one side or both sides of your back or abdomen as well as fever/chills if there is an infection involved.

The Lowdown on Blueberries

According to some studies , It has been said ‘Overconsumption’ of oxalate-rich foods namely spinach ,beetroot etc,in combination with insufficient water intake causes calcium oxalate crystals formation leading directly into the formation glandular debris within kidneys inviting further embarrassment locally affectionately named ‘stones’.

One cup (148 grams) of fresh blueberries contains:
– Calories: 84
– Carbs: 21 grams
– Fiber: 4 grams
– Vitamin C: 24% of the RDI (recommended daily intake)
– Vitamin K: 36% of the RDI
– Manganese: 25% of the RDI

Oxalates and Kidney Stones

So, what exactly are oxalates and why do they matter for kidney stones? Oxalate is a naturally occurring substance found in many foods, including blueberries. Other high oxlate containing food include almonds, cashews, potatoes etc.

When we consume oxalate-containing foods , our body absorbs some of it into the bloodstream. Usually it then moves out through urine but when too much calcium binds to oxlate within kidneys leading to formation .This forms crystals that can combine with other substances like calcium to form kidney stones if there’s not enough fluid available in your body ie dehydration/hypertension / diabetes .

Are Blueberries High In Oxalates?

While blueberries do contain small amounts of oxalate compared to other foods like spinach or beetroot ,they themselves cannot be named as responsible receptors inviting stone formations as their concentration is considerably low making them an ideal snack option.However berries grown on different soils may give raise marginally varying results

In fact, studies show that consuming moderate amounts of blueberries does not increase your risk for developing kidney stones unless any underlying disorders from before already prevails.

So should you avoid eating blueberries altogether just because they contain some amount of oxlate? NOPE relaxing sigh.Blueberry consumption doesn’t cause more than average problems;however can lead lead towards faintly noticeable impairment especially within ‘Kapha’ identified constitutions by Ayurvedic medicine .

The conclusion however stands clear-cut : people who eat balanced diets don’t have to stop enjoying fruit salads featuring these beautiful fruits!

The Bottom Line

Although no direct correlation between high levels of blueberry consumption has been observed to kidney stones yet, moderation is still the key. Consuming too much of anything can lead to multiple health problems and blueberries being a fruit should be enjoyed in limits so as not predominantly one-sidedly depend on oxlate . In other words, enjoy your blueberries but just remember – everything in moderation! not sure if mic drop moment.
