Kidney stones are solid crystals forming in the urine. Pain from kidney stones can be unbearable and comes in waves. Unfortunately, your diet can trigger the problem. Here are some types of foods that can increase the risk of kidney stones you should know.
Sodium is a part of salt. Sodium in foods you eat can trigger the formation of kidney stones because it increases the amount of calcium in your urine. Sodium can be found in canned foods, fast foods, and packaged foods; or meat, seasonings, and condiments. Thus, you can discuss with your healthcare provider about how much sodium should be added to your diet. Reducing sodium intake can also help protect your heart.
Here are some tips to help you have a low-sodium diet:
- Always know your amount of sodium. Check if you eat at home.
- When you eat out, avoid foods that contain too much sodium. You can check with the restaurant.
- Get rid of canned soup, meat, vegetables, fast foods and packaged foods. Choose fresh foods
- When you buy foods at the supermarket, look at the labels. You should avoid foods that contain sodium bicarbonate, baking soda, baking powder, disodium phosphate, monosodium glutamate, MSG, sodium alginate, sodium nitrate or nitrite. These are hidden sodium.
Foods raising the amount of oxalate
Oxalate can prevent your body from absorbing calcium. So calcium level can rise in your urine and contribute to kidney stones. Foods that are rich in oxalate include:
- Sweet potatoes
- Nuts such as walnuts
- Soy products
- Strong black tea. If you like tea, you can drink herbal tea such as lemon, chamomile, mint tea.
Foods containing animal protein
Eating too much animal protein can increase the level of uric acid and reduce the levels of citrate. Citrate can prevent stones from developing. Thus, high level of uric acid and low levels of citrate can increase your risk of kidney stones.
Animal protein such as pork, poultry, beef, chicken, eggs, fish, shellfish, milk, and milk products should be limited. However, make sure you get enough animal protein because your body still need it. You can discuss with your healthcare provider about how much animal protein you should eat. Plant-based protein can be considered, such as:
- Beans, peas, peanuts
- Sunflower seeds
- Soy products
However, peanuts, soy products, and nuts can increase your risk of calcium oxalate kidney stones.
