13. Berries
Berries are a nutritious and delicious addition to any diet, but certain types of berries can increase the risk of kidney stone formation. Berries like strawberries, blackberries, raspberries, and blueberries are high in oxalates, which can combine with calcium in the urine to form calcium oxalate, the most common type of kidney stone.
While these berries are still a healthy choice, it is important to consume them in moderation and pair them with calcium-rich foods to help bind oxalates in the digestive tract. Pairing high-oxalate foods with calcium-rich foods can help prevent the oxalates from being absorbed and excreted in the urine, reducing the risk of kidney stone formation.
In addition to pairing high-oxalate berries with calcium-rich foods, it is also important to drink plenty of water to help flush out any excess calcium and oxalates in the urine. Drinking enough water can help prevent urine from becoming concentrated, reducing the risk of kidney stone formation.
It is important to note that not all berries are high in oxalates. Some berries like cranberries, elderberries, and currants are lower in oxalates and can be a safer choice for those at risk of kidney stones. These berries also have other health benefits, including anti-inflammatory and antioxidant properties.
