If you want healthy kidneys, eat pineapple regularly.

Kidney stones are a fairly common health problem, with about 1 in 10 people having kidney stones at some point in their lives, according to the National Kidney Foundation. Large kidney stones can cause symptoms such as lower back pain, blood in the urine, fever, or smelly urine. These are symptoms that indicate the kidney stone cannot be passed through the urinary tract and requires medical assistance, according to the US health website Healthline .

Pineapple is rich in water, potassium, magnesium and citric acid which helps prevent kidney stones.

Low fluid intake and low urine output are major risk factors for kidney stones. Diet also plays an important role.

A diet high in sodium, meat, low in calcium and low in water intake increases the risk of kidney stones. This is because these foods make the concentration of minerals in the urine more concentrated and acidic. This condition makes it easier for crystals to deposit and form in the kidneys into kidney stones.

Meanwhile, fruits and vegetables can help prevent kidney stones thanks to their high water content and important nutrients such as potassium, magnesium and citric acid. The ideal fruit to help prevent kidney stones is pineapple.

Pineapple is very juicy because 86% of pineapple is water. In 100 grams of pineapple, there will be about 680 mg of citric acid, a substance that can help prevent calcium oxalate kidney stones.

One of the benefits of pineapple in preventing kidney stones is that it reduces acidity in the body. This may sound confusing because pineapple is rich in citric acid but has an acid-reducing effect. In fact, foods that are high in acidity do not increase acidity in the body.

The acidity level used to assess kidney stone risk is the potential renal acid level (PRAL). This is the amount of acid your body produces as a result of metabolism, including the digestion of certain foods. PRAL depends on many factors, such as the amount of protein, phosphorus, potassium, magnesium, and calcium in the food.

Foods high in protein and phosphorus will create high levels of acid in the body. Meanwhile, foods containing potassium, magnesium and calcium reduce acid levels in the body. Pineapple is a food rich in these natural minerals, so it has the effect of reducing acid levels in the body, thereby reducing the amount of acid in the urine, helping to prevent kidney stones, according to Healthline .
