The Dangers of Adding Salt to Your Coffee
Coffee is one of the most popular beverages around the world, with millions of people relying on their daily cup of joe to help wake them up and get them going in the morning. However, some people have taken to adding a pinch of salt to their coffee grounds before brewing, claiming that it reduces the bitter taste and enhances the natural flavors. But is this harmless hack actually safe or beneficial in any way? Let's take a closer look at the potential dangers of adding salt to coffee.
Impact on Flavor
Salt is commonly used in cooking and baking to help balance and enhance the flavors of dishes. So it would seem logical that adding a dash of salt to coffee grounds could also improve the flavor. Some people do report that this trick smooths out the bitterness and acidic taste of coffee. However, the impact is generally subtle, and it more likely has to do with the chemistry of the brewing process rather than making the coffee taste saltier.
The amount of salt used is small enough that it likely won't register on your taste buds. A pinch of salt, even when dissolved in water, does not make the liquid taste very salty at all. So while the salt may chemically react with acids in the coffee during brewing, leading to a less bitter brew, you are unlikely to notice a major flavor enhancement from the salt alone.
No Proven Benefits
There is no definitive scientific research or evidence that salting coffee grounds before brewing provides any tangible benefits. Much of the hype comes from individual anecdotes and testimonials rather than hard facts. Adding small amounts of salt to coffee grounds may produce subtle effects on the brewing process and finished flavor. But the impact, if any, is likely to be minimal.
The chief concerns around this trend have more to do with potential downsides than any expectation it will drastically improve your daily cup of coffee. Without clear benefits, most experts and coffee purists advise drinking high-quality coffee as-is without adulterants like salt.
Health Risks
The main health concern with adding salt to your coffee has to do with increased sodium intake. The 2015-2020 Dietary Guidelines for Americans recommend limiting sodium intake to less than 2,300 milligrams per day. Most Americans already consume too much sodium, averaging over 3,400 mg per day.
Each teaspoon of salt contains about 2,300 mg of sodium. So if you are adding multiple pinches of salt to your coffee over the course of a day, it can start to add up in your dietary sodium intake. Consuming excess sodium puts you at higher risk of hypertension, heart disease, kidney disease, stroke, and other health problems. It's best not to treat your daily coffee as an opportunity to increase salt consumption.
Other Contaminants
There are also concerns that adding salt to coffee grounds could potentially introduce contaminants into your brew. Salt is hygroscopic, meaning it absorbs moisture from the surrounding environment. Table salt typically contains anti-caking agents to prevent clumping. The salt can pick up dirt and germs from hands and utensils used to scoop and pinch it. Damp salt can also breed bacteria.
When you directly add the salt to the coffee grounds right before brewing, any contaminants will flow straight into your pot or cup. This introduces unnecessary health risks, especially if you use raw salt that hasn't been treated to prevent clumping and killing microbes. Even purified table salt can harbor unsanitary elements if not stored and handled properly.
Better Alternatives
Rather than salting your coffee, you have many safer options to improve the flavor:
- Use high-quality coffee beans and brew them properly.
- Opt for coarser coffee grounds to reduce over-extraction of bitter compounds.
- Play around with different coffee to water ratios to optimize the strength.
- Experiment with small amounts of spices like cinnamon or nutmeg to enhance flavor.
- Try cold brew methods that result in sweeter, smoother coffee flavor.
- Add a dash of vanilla, cocoa powder, cinnamon, or other natural flavors.
- Use milk, cream, foamed milk, or sweeteners to balance acidity and bitterness.
In general, you'll get the best results by starting with quality coffee beans and using proper brewing techniques. Salt is an unnecessary shortcut that likely won't improve your coffee experience.
Health Risks of Drinking Coffee with Salt
We've established that adding salt to coffee grounds comes with some potential downsides and no proven benefits. But what are the specific health implications of actually drinking coffee with salt added to it? Here are some of the top risks to be aware of.
Increased Blood Pressure
One of the most well-established effects of high sodium intake is elevated blood pressure. Hypertension, or chronic high blood pressure, significantly increases your risk of heart attack, stroke, kidney failure, and other serious health issues.
Even a single dose of excess sodium can cause a temporary spike in blood pressure in those with existing hypertension or prehypertension. Habitually salting your coffee and consuming those extra doses of sodium daily can cause chronic blood pressure elevations.
Caffeine also has links to raised blood pressure, especially at higher intakes. The combination of caffeine and excess sodium from salted coffee could be a double whammy for your heart health.
Increased Heart Disease Risk
Higher blood pressure due to excess sodium places extra strain on the heart and arteries, which can increase the likelihood of cardiovascular disease over time. The risks go beyond just hypertension, as excess sodium intake is independently associated with higher risks of stroke, heart attack, and heart failure.
Again, caffeine also has its own links to heart health issues at high intakes. So adding caffeine's effects on the heart on top of sodium's impacts is best avoided for heart health.
Fluid Retention
One of sodium's effects in the body is promoting fluid retention. Sodium attracts and holds extra fluid in the bloodstream and tissues. For those with congestive heart failure or kidney disease, this fluid retention can be dangerous and exacerbate complications.
Even in otherwise healthy people, habitual excess sodium intake can translate to fluid retention and increased risk for edema (swelling). Caffeine has its own links to fluid excretion via the kidneys, so pairing it with extra sodium could have a compounding effect.
Increased Kidney Burden
Excess sodium places extra strain on the kidneys which have to work harder to filter out and excrete the extra sodium load. Habitual high sodium intake is linked to greater risk of kidney disease and kidney stones over time.
Caffeine also increases kidney burden and stress in high amounts. So the combination of high sodium intake from salted coffee plus the caffeine exerts a double burden on the kidneys that could increase the likelihood of chronic kidney dysfunction.
Gastrointestinal Issues
Some people report stomach pain, nausea, and diarrhea when drinking coffee with salt added. Consuming excessive sodium can cause gastrointestinal distress in some individuals. The caffeine in coffee already has links to GI symptoms like diarrhea in those sensitive to its effects.
Together, the sodium and caffeine in salted coffee may overstimulate the digestive system. Those already prone to stomach issues may want to be cautious and limit or avoid salted coffee.
Stay Hydrated and Drink Healthy Beverages
Overall, adding salt to coffee seems to carry more risks than benefits. While an occasional salted coffee may not be detrimental for most people's health, making it a daily habit could increase your risk of chronic disease over time. There are many healthier ways to optimize coffee's flavor and reduce bitterness.
If you have high blood pressure, heart disease, kidney disease or regularly experience GI issues, it's best to avoid salted coffee given its sodium and caffeine content. Be sure to stay well hydrated by drinking plenty of water and healthy beverages that don't exacerbate medical conditions.
With some caution and moderation, coffee can be part of a healthy diet and lifestyle for many people. But adding salt offers negligible benefits for flavor while carrying health risks. You're better off skipping the sodium and salt and finding other ways to enjoy your daily cup of joe.
