Is Green Tea Bad for Kidney Stones?

Kidney or renal stones is a painful and in most cases a recurrent disorder of the renal system. Kidney stones are produced by calcium oxalate which is a substance present in food. Drinking green tea can certainly help in preventing formation of calcium oxalate kidney stones. Scientists at the University of Sichuan in Chengdu, China, discovered that green tea is quite beneficial in stopping the growth of calcium oxalate which significantly cuts down the risk of kidney stones. The results show that an increase in the consumption of green tea alters the shape and form of the calcium oxalate crystals thereby decreasing the risk for stone formation.

But there are some contraindications to green tea, which are very similar in all varieties of tea. Keep in mind that tea contains caffeine, so people suffering from hypertension, pregnant women and children should not consume it.

It is also believed that the consumption of tea hinders the absorption of iron in meals. This is why it is always advisable to drink tea at least half an hour before or after eating.

There are simple measures to prevent this disease, keeping your kidneys healthy, such as the following:

-Drinking lots of water and liquids make a big difference since then the salt concentration decreases in the urine.

-Avoid sugary drinks.

-It is advisable to consume foods that contain magnesium; a micronutrient favors the functioning of the kidneys and helps to prevent infections.

-Performing physical activity regularly allows a proper absorption of calcium, preventing it from building up forming kidney stones.

-They also help to activate circulation, which is very important to encourage the elimination of kidney stones.

-You should avoid the consumption of excess sodium and corn syrup.

-Urinate as soon as you feel like it and not hold it, otherwise, it can cause infections and worsen the disease.

-Stress weakens the defenses and makes people more prone to infections and diseases.

-Decrease the amount of salt in your diet.

-Moderate foods that are known to increase the risk of the stone formation such as rhubarb, nuts, spinach, and chocolate.

-Take natural diuretics based on dandelion, which helps to remove stones; you can also drink basil tea, peaches, and pomegranate juice.

-A balanced diet is essential to avoid kidney stone formation. It is not enough to avoid table salt; many processed foods contain large amounts of sodium.

-Give priority to fruits and vegetables, decreasing protein intake, especially if there is excess uric acid, substituting red meat for white and consuming it in moderation.

-Other foods to moderate apart from the red meats are the viscera, the dairy, and the eggs. To prevent oxalate kidney stones, seafood, chocolate, spinach, peppers, and bluefish should be moderated instead.

What to Eat to Avoid Kidney Stones?

-The asparagus is excellent; they diminish the acidity of the urine, to avoid the precipitation of the salts.

-Include fresh parsley in your diet, as it is an excellent diuretic and anti-inflammatory. Likewise, the basil can be very useful in the treatment of stones; it is advisable to consume it with their salads.

-Add legumes to your diet such as beans, with high magnesium content. The cooking water of these grains is also very beneficial for kidney health.
