Citrate helps prevents kidney stones and is in lemonade.

Have you ever passed a kidney stone before? If so, you know it’s terrible! I’ve met women who would rather deliver a baby! Fortunately, there are a few dietary changes you can make to help prevent their formation.

In the video below, Dr. James Farrell discusses dietary recommendations that help prevent kidney stones.

Here are 5 dietary recommendations that can help prevent kidney stones

Drink more water!

1) Drink more water

You want to try and make about 2.5 liters of urine in a day. I know we don’t all pee in a measuring cup, or hopefully not many of us at all.

Therefore, here is how to tell you’re hydrated enough:

  1. If your urine is clear, you’re hydrated.
  2. If it’s yellow, drink more water. Not soda or juice, more water!

Note: If you’re not drinking enough water, consider one of the following products to help you do so.

Eat less salt to prevent kidney stones

2) Eat less salt

While most kidney stones are calcium based, it’s how much salt your kidney sees that really matters. When I say salt or sodium, I’m using them interchangeably as they mean the same thing.

I have a lot of patients who say “doc, it’s not a problem – we don’t add table salt to our food so I think we’re good there.” You might be good, but humor me for a second.

The majority of salt in our diet comes from canned, boxed, packaged, processed and fast food. And we all need salt to live but we don’t need too much.

In fact, we should be getting about 2 to 2.3 grams of salt in our diet a day (or 2,000 milligrams to 2,300 milligrams).

Carefully review nutrition facts to make sure you're not eating too much salt or sodium

Remember that 1 gram is 1,000 milligrams. The reason this matters is I want you to look at the food labels of the things you buy. It’ll say sodium in milligrams and everything is based off serving sizes. In doing so, you have a rough idea of how much salt you have in your body on a daily basis.

See where your big salt loads are and where you can make some changes. The easy changes are buying from packages or companies that have less salt in them upfront.

Also, low and no salt added foods are available, you just have to look for them a little bit – and I don’t think you’re going to miss the taste.

For all those foods that don’t have a label, like produce or if you eat out at chain restaurants, you can actually google that stuff. Most of the time you can find out how much sodium is in what you’re eating.

Overall, get a rough idea of where you are. Are you consuming 3 grams a day? 2 grams a day? 4 grams a day? See where you can make some changes.

Citrate helps prevents kidney stones and is in lemonade.

3) More citrate

Have you ever had someone say “If you have kidney stones, just drink lemonade!”?

Lemon and limes have citrate in them.That’s where this comes from. Lemons have citrate in them. Citrate is a molecule that inhibits the ability of calcium to stick together and make a kidney stone. Limes also have a lot of citrate.

You can buy them, slice them up, squeeze them in your water – consider that your vitamins. If you’re going to do whole limes or whole lemons, drink through a straw or gulp it so you don’t hurt the enamel on your teeth. If you don’t like lemons or limes, then you can get a lot of citrate from fresh tomatoes.

Also, if you make uric acid stones, citrate will actually dissolve them because citrate helps with some acid/base status in your body and stones have a lot to do with acid/base status.

The other thing here is that citrate it’s water soluble. This means that any excess that you have you’re just going to pee out. Therefore, it’s hard to have too much citrate.

4) Eat less animal-based protein

For people who like numbers, I tend to say 70 grams or less. For people who like portions, go for 4 to 6 ounces twice a day and that should be the amount of animal base protein you have because it’s higher in acid and will help you make more stones.

People who are vegetarians make fewer stones. Also, soy-based protein has less acid, so there is less likely for kidney stones there.

Oxylates are in berries.

5) Lowering oxalates

This one gets a little tricky. The most common stone is calcium oxalate. Oxalates are naturally in all sorts of plant material. They’re also in lots of stuff that is good for us such as spinach, nuts, berries, tea, coffee, chocolate, and alcohol.

Oxylates are also in potatoe chips.

Therefore, it gets tough to say a low oxalate diet since that may take some stuff away. Also, they’re pretty high in potato chips and french fries, so we can all probably do a little better there.

Having too much Vitamin C can increase your oxylate contents and put you at risk for kidney stones.

Lastly, if you have more than 500 milligrams of Vitamin C, that’s going to increase your oxalate contents. Therefore, try and stay below 500 milligrams.

Final thoughts on kidney stones

Now a lot of people rightfully ask, “Wait a second, if calcium stones are what we’re making, why not drop calcium?” The answer for that is that low calcium diets increase your ability to make stones.

If I give you that mechanism, you’re probably going to fall asleep. Just recognize that calcium supplements and normal calcium diets are OK!

Now, some people have medical problems that make or cause them to make a lot of stones. For all this information, please see your doctor as well. However, recognize that these are great dietary tips to reduce your ability to make stones.
