How to eat it

Eat the soup in small sips throughout the day, at room temperature if possible. If you like, you can add a little bit of lemon juice to it.

It’s highly recommended that you consume at least two glasses of onion soup on an empty stomach at least half an hour before breakfast. Try to consume the soup every day before midday so you don’t have to go to the bathroom at night.

The 9-day cure

The depurative kidney cure that we recommend lasts nine days. Along with consuming the soup, follow these suggestions:

  • Try to cut your salt and salty food intake. You can add salt to your meals with a little bit of salt water (sold in natural product shops and some supermarkets).
  • Reduce your consumption of animal proteins (especially meat, milk, and dairy products) and prioritize vegetable proteins. Adzuki beans are excellent for your kidneys. Other sources of vegetable protein besides legumes are dried fruits and mushrooms. You can also eat eggs and a little bit of fish.
  • Avoid refined sugar and sugary foods. Use honey or stevia to sweeten.
  • Kidneys, along with the liver, are the main organs that tend to get cold and worsen kidney diseases and also cause a lack of energy, fatigue, and pains in the lumbar region. In order to prevent this, always keep the middle and lower area of your back warm. At night, you can put a hot compress on it.
  • If you do physical activity and you sweat, this will help loosen your kidneys. By overworking them, you help your body eliminate fluids.
