What to eat and drink
If you’re trying to avoid kidney stones, what you eat and drink is as important as what you shouldn’t eat and drink. Here are some important rules of thumb to keep in mind.
Stay hydrated
Fluids, especially water, help to dilute the chemicals that form stones. Try to drink at least 12 glasses of water a day.
Up your citrus intake
Citrus fruit, and their juice, can help reduce or block the formation of stones due to naturally occurring citrate. Good sources of citrus include lemons, oranges, and grapefruit.
Eat lots of calcium (and vitamin D)
If your calcium intake is low, oxalate levels may rise. It’s preferable to get your calcium from food, rather than from supplements, as these have been linked to kidney stone formation. Good sources of calcium include milk, yogurt, cottage cheese, and other types of cheeses. Vegetarian sources of calcium include legumes, calcium-set tofu, dark green vegetables, nuts, seeds, and blackstrap molasses. If you don’t like the taste of cow’s milk, or, if it doesn’t agree with you, try lactose-free milk, fortified soy milk, or goat’s milk. Also make sure to include foods high in vitamin D each day. Vitamin D helps the body absorb more calcium. Many foods are fortified with this vitamin. It’s also found in fatty fishes, such as salmon, egg yolks, and cheese.
Food and drinks to avoid on a kidney stone diet
Limit salt
High sodium levels in the body, can promote calcium buildup in urine. Avoid adding salt to food, and check the labels on processed foods to see how much sodium they contain. Fast food can be high in sodium, but so can regular restaurant food. When you’re able, ask that no salt be added to whatever you order on a menu. Also, take note of what you drink. Some vegetable juices are high in sodium.
Lower your animal protein intake
Many sources of protein, such as red meat, pork, chicken, poultry, fish, and eggs, increase the amount of uric acid you produce. Eating large amounts of protein also reduces a chemical in urine called citrate. Citrate’s job is to prevent the formation of kidney stones. Alternatives to animal protein include quinoa, tofu (bean curd), hummus, chia seeds, and Greek yogurt. Since protein is important for overall health, discuss how much you should eat daily with your doctor.
A plant-based diet may be ideal
Eat oxalates wisely. Foods high in this chemical may increase formation of kidney stones. If you’ve already had kidney stones, you may wish to reduce or eliminate oxalates from your diet completely. If you’re trying to avoid kidney stones, check with your doctor to determine if limiting these foods is enough. If you do eat foods containing oxalates, always make sure to eat or drink a calcium source with them. This will help the oxalate bind to the calcium during digestion, before it can reach your kidneys. Foods high in oxalate include:
chocolate
beets
nuts
tea
rhubarb
spinach
swiss chard
sweet potatoes
Don’t drink colas
Avoid cola drinks. Cola is high in phosphate, another chemical which can promote the formation of kidney stones.
Reduce or eliminate added sugar intake
Added sugars are sugars and syrups that are added to processed foods and drinks. Added sucrose and added fructose may increase your risk of kidney stones. Keep an eye on the amount of sugar you eat, in processed foods, such as cake, in fruit, in soft drinks, and in juices. Other common added sugar names include corn syrup, crystallized fructose, honey, agave nectar, brown rice syrup, and cane sugar.
