Here are the foods you should avoid when you have kidney stones, which include salt-rich foods, oxalate-rich foods, fatty foods, and more than 3-ounces of meat daily.

Kidney stones can leave you wondering about which foods to cut out of your diet.

When you have kidney stones, it is essential to monitor your diet to prevent aggravation of the condition. Limiting certain foods or avoiding certain foods can prevent the formation of further stones.

Here are the foods you should avoid eating when you have kidney stones:

  • Consume less salt.
    • Chinese and Mexican food, tomato juice, regular canned foods, and processed foods are often high in salt.
    • A high-sodium diet can produce kidney stones because it increases the amount of calcium in your urine.
  • Limit foods that are high in oxalates if you have a calcium oxalate stone.
    • Fruits: Currants, canned fruit salad, strawberries, and Concord grapes
    • Vegetables: Beets, rhubarb, leeks, summer squash, sweet potatoes, and spinach
    • Drinks: Tea and instant coffee
    • Other foods: Grits, tofu, nuts, tomato soup, and chocolate
  • Avoid these foods if you have a uric acid stone:
    • Alcohol
    • Anchovies
    • Asparagus
    • Baking or brewer's yeast
    • Cauliflower
    • Consommé
    • Gravy
    • Herring
    • Legumes (dried beans and peas)
    • Mushrooms
    • Oils
    • Organ meats (liver, kidney, and sweetbreads)
    • Sardines
    • Spinach
  • Avoid fatty foods such as salad dressings, ice cream, and fried foods.
  • Avoid consuming more than three ounces of meat each day.
  • Avoid colas because they are high in phosphate.
    • Phosphate promotes the formation of kidney stones.
    • Moreover, reduce or eliminate added sugar intake.
  • Restrict or completely avoid caffeine because it tends to drain out fluids from your body, causing dehydration.

What foods and drinks can be included if you have kidney stones?

Certain foods that are low in oxalate or promote the excretion of calcium ions should be consumed during this time. Hydrating yourself with sufficient fluid is extremely important to prevent all types of kidney stones. Water dilutes the urine, preventing stone formation.

Fluids to be consumed during kidney stones include:

  • Drink adequate fluids, particularly water
  • Fluids such as ginger ale, lemon water, and fruit juices (without added sugar and salt)

Drink enough fluid to urinate at least two liters in 24 hours. Dark urine can indicate that your body is not getting sufficient water.
