Hidden Salt Bombs

One of the most common exclamations I hear during patient consults is, “I never use the salt shaker!”

I wish it were as easy as putting down the salt shaker. The other common issue I hear is that patients really struggle to keep their sodium intake down each day. It is very hard, especially when you eat out a lot. I am not saying you can never have a high-salt day, because we do not form kidney stones overnight, but what we do each day, month over month, year after year, matters. Also, because many of you do not know this, 1 teaspoon of salt that you add to your recipes has 2,300 mg/sodium. Hard to believe, isn’t it?

Important note before we start…

The sodium numbers below are estimates. Brands vary. Recipes change. That’s exactly why reading nutrition labels matters and my mantra of “Turn it around, Buster Brown” is required when lower daily sodium levels are needed.

If a food has a label, read it. If it doesn’t have a label, assume it’s higher than you think and try to find lower sodium options.

What “low-sodium” actually means: 140mg sodium or less per serving

What is the Kidney Stone Diet® guideline for sodium? 1,500 mg/day (not under)

Why does this matter for kidney stones? Sodium increases urine calcium and lowers urine volume.

Higher urine calcium levels raise stone risk—even when hydration is good. Too much calcium in the urine can also lower bone density.

This is why so many patients are shocked by their urine results while “eating healthy.”

What I want you to do this week:

• Start reading nutrition labels on foods you eat often.
• Respect serving sizes.
• Notice how many salty foods stack in a single day.

That awareness alone changes outcomes. Remember, your goal is 1,500mg of sodium per day to lower stone risk (the American Heart Association has lowered its guidlines to this number as well), not less.

How do you find out your risk factors for kidney stones? Ask your doctor to order a 24-hour urine collection. It is the number one thing to do, so you know why you are forming kidney stones.

A urine collection gives you numbers—but someone has to translate them. I help patients understand their results so their next doctor visit is clearer and more focused. It is my specialty.
