It’s a common scenario: you find yourself reaching for the salt shaker or craving salty snacks. While excessive sugar intake often takes center stage in health discussions, the science behind salt cravings and how to manage them is equally important. So, what’s driving your desire for salty foods, and what steps can you take to moderate your sodium consumption? We consulted with nutrition experts to delve into the reasons behind salt cravings and offer guidance on maintaining a healthy sodium intake.
Potential Reasons You’re Craving Salt
Often, the reasons behind your salt cravings are linked to your daily life and environment. If you feel like you’re constantly battling an urge for salty foods, take heart – there are actionable steps you can take to regain control.
Stress
When life gets overwhelming, stress can significantly influence your eating habits. It often triggers cravings for comfort foods due to its impact on hormone levels. For some, stress can suppress hunger, while for others, it intensifies it. If you’re someone who finds themselves needing savory snacks or meals when stressed, you likely fall into the latter category where appetite increases with stress.
“The next time you experience a salt craving, take a moment to evaluate your overall stress level,” advises registered dietitian Elysia Cartlidge, MAN, RD. “Stress can affect your adrenal glands and their ability to regulate sodium. This dysregulation can frequently lead to heightened cravings for salt.”
Your adrenal glands are responsible for producing cortisol, often called the “stress hormone.” During times of increased stress, cortisol fluctuations might be the underlying cause of your salt cravings.
While eliminating stress overnight isn’t feasible, you can adopt stress management techniques and become more aware of when you’re feeling stressed. This increased awareness can help prevent stress from drastically dictating your eating patterns.

Sweating
Regular physical activity is beneficial for your health, but it can also contribute to cravings for salty foods. Sodium is a crucial electrolyte that is lost through sweat (which explains the popularity of electrolyte-rich sports drinks).
“If you’ve been engaging in intense workouts and sweating profusely, the increased sweat production could lead to a significant loss of sodium from your body,” Cartlidge explains. “This sodium loss can trigger your body to crave more salt in order to replenish what’s been lost.”
Unless you are consistently pushing your body to extreme exertion, this isn’t a reason to reduce your exercise. Instead, focus on making informed choices about your sodium sources and prioritize hydration throughout the day, not just after workouts.
Consuming an electrolyte drink after a strenuous, sweat-inducing workout can effectively address both electrolyte replenishment and hydration. However, it’s important to remember that relying on sports drinks constantly isn’t the healthiest approach to electrolyte balance. A well-rounded diet rich in whole foods, fruits, and vegetables remains the optimal source of electrolytes.

Exhaustion
When you are sleep-deprived, your appetite can become seemingly limitless, and your ability to resist tempting cravings diminishes. This makes it much easier to succumb to that plate of nachos or a bowl of ramen. Similar to stress, this hormonal interplay is at work. Hormones like cortisol, leptin, ghrelin, and serotonin play roles in regulating hunger and driving your search for foods that provide a sense of well-being.
“Insufficient sleep can disrupt your hunger, stress, and ‘feel-good’ hormones, potentially amplifying your cravings for salt,” Cartlidge points out. “If you’re not getting adequate rest, you might experience increased appetite, reduced self-control around your food cravings, and a general feeling of unease due to a drop in serotonin. This can lead you to reach for salty foods like chips or french fries in an attempt to boost your mood.”
It’s often easier said than done, but prioritizing sufficient sleep each night is crucial. Adults generally need seven to nine hours of sleep per night, according to health guidelines.

Dehydration
Are you consuming enough water and hydrating foods such as fruits and vegetables daily? If you’re unsure, you might be experiencing mild dehydration, which can intensify your desire for sodium. Interestingly, it’s easy to mistake thirst for hunger. “If you’re not adequately hydrated and misinterpreting dehydration as hunger, this can lead to salt cravings,” Cartlidge explains.
Dehydration can also disrupt electrolyte balance, similar to the effects of excessive sweating. “This is particularly relevant for athletes or highly active individuals who experience greater fluid loss through sweat and are not properly rehydrating and replenishing lost electrolytes after intense activity and sweating,” she says. “In such cases, the craving for salt is the body’s way of signaling the need for fluid replacement, sodium replenishment, or both.”
Try drinking water before or during your salty snack fix to avoid confusing hunger and thirst cues. Alternatively, opt for a hydrating salty snack like celery sticks with hummus.

Boredom
You might find yourself in a routine that’s difficult to break, such as consistently grabbing a side of fries on your way home from work each evening. “If you’re accustomed to reaching for a salty snack during a mid-afternoon lull or while watching TV at night, your cravings might simply be habit-related or stem from boredom,” Cartlidge suggests. “Salty snacks are often convenient, and you might find yourself choosing them simply because they’re readily available.”
Breaking ingrained habits can be challenging—especially when they’re so enjoyable—but you can interrupt boredom snacking by replacing unwanted habits with new, positive ones. Engage your mind and hands with alternative activities, such as taking an evening walk or doing household chores. You can also substitute high-sodium processed snacks with healthier alternatives. Nutrient-rich foods can often satisfy that “salty tooth” as well—consider options like edamame, guacamole, savory oatmeal, or nuts.
Distinguishing between true hunger and boredom-driven cravings can be tricky. Genuine hunger is usually accompanied by physical cues like stomach growling, low energy, and difficulty concentrating. Eating simply to pass time or alleviate monotony is more likely driven by boredom and may lack those typical hunger signals.

Dietary Restriction
If you’ve previously attempted to reduce your sodium intake, you may have imposed strict dietary rules on yourself. Perhaps you tried to eliminate all added salt from your diet. While this approach seems logical in theory, excessive dietary restrictions can sometimes backfire.
“From a psychological perspective, intentionally restricting foods you once enjoyed can lead to an over-fixation on them, and they suddenly become the only thing you can think about,” explains dietitian Sarah McIntyre. “When we try to force ourselves into a rigid ‘no salty foods’ rule, it becomes the central focus of our food thoughts, eventually driving you to seek it out, often leading to overconsumption.”
Set realistic, achievable goals. Unrealistic goals can lead to discouragement if you don’t meet them perfectly. Start gradually and progressively reduce your sodium intake instead of abruptly cutting it out completely. And allow yourself occasional indulgences.

Premenstrual Syndrome (PMS)
Your menstrual cycle can also play a role in your salt cravings. Hormonal fluctuations associated with PMS can intensify hunger cues and the desire for stimuli that evoke positive feelings.
Research indicates that individuals experiencing PMS often exhibit an increased craving for foods high in salt, as well as foods rich in sugar and fat, during the premenstrual phase of their cycle.
Emerging research suggests that calcium intake might help alleviate PMS symptoms. Vitex (chasteberry), a herbal remedy, may also offer relief. Over-the-counter pain relievers and oral contraceptive pills have also been shown to help manage certain PMS symptoms.

Genetics
The role of genetics in salt cravings is still an area of ongoing research. Whether some individuals are genetically predisposed to crave salty foods over sweet ones remains a mystery, but a genetic influence cannot be entirely ruled out.
“We all have our individual preferences,” notes dietitian Mary Stewart Poulson, RD, CDCES. “Genes significantly influence these preferences through our taste buds and taste sensitivity. People with heightened taste sensitivity might be more inclined to add salt to their food.”

Addison’s Disease
Many common reasons for salt cravings are related to lifestyle factors that are within your control. However, in some cases, salt cravings can be associated with underlying health conditions. Cartlidge mentions that conditions like Addison’s disease can be a potential cause.
“Addison’s disease is a rare condition that develops when the adrenal glands are damaged and don’t produce sufficient amounts of the hormones cortisol and aldosterone,” she explains.
“These hormones are crucial for regulating fluid and sodium levels in the body. If the body isn’t retaining salt effectively, it can result in increased cravings for salty foods and snacks.” Common symptoms of Addison’s disease include persistent fatigue, muscle weakness, loss of appetite, weight loss, and abdominal pain. It can also be accompanied by nausea (with or without vomiting or diarrhea), joint pain, and other symptoms.

How Much Salt Is OK to Eat?
Sodium is an essential mineral and plays a vital role in a balanced diet. However, our daily sodium needs are significantly less than what most people typically consume.
Consulting the Recommended Dietary Allowance (RDA) for nutrients can help you determine if your sodium intake is excessive or within a healthy range. The 2020-2025 Dietary Guidelines for Americans recommend limiting sodium intake to less than 2,300 milligrams per day. The American Heart Association aligns with this recommendation but suggests that 1,500 milligrams or less per day is even more beneficial for heart health.
To put these numbers into perspective, a 1-ounce bag of potato chips contains approximately 150 milligrams of sodium, according to USDA data. In comparison, a tablespoon of peanut butter has about 69 milligrams of sodium, also per the USDA.
However, the average sodium consumption among Americans is estimated by the CDC to be around 3,400 milligrams daily, exceeding the recommended amount by over 1,000 milligrams. If you regularly indulge in salty snacks, you might be satisfying your salt cravings more than your body truly requires.
How to Lower Your Salt Intake and Curb Cravings
The primary reason we crave salty foods is simply because they taste delicious. The key to managing salt cravings is to retrain your taste buds to appreciate the flavor of foods with less added salt. Here’s how to implement this:
Gradually Reduce Intake
“Reducing salt intake is a gradual process, and it takes time for our taste buds to adapt,” Cartlidge explains. “As you slowly decrease your salt consumption, your taste buds will become less tolerant to the intense taste of salt, and you may find that your cravings for it naturally diminish over time.”
Make Healthier Versions of Your Favorite Foods
Instead of relying on processed, pre-made convenience foods, which are often high in added salt for flavor and preservation (think frozen burritos, microwaveable hash browns, pre-cooked sausages), try preparing these dishes at home. You’ll often discover that the problem isn’t salt itself, but rather the excessive amounts added to packaged foods.
Be Mindful of What You’re Eating
When you’re short on time and need to opt for packaged foods, Cartlidge advises becoming familiar with reading nutrition labels. Look for products labeled “reduced sodium” or “no salt added.” Specifically, aim for labels indicating 5% or less of the daily value of sodium per serving.
Flavor Foods with Other Spices
Remember that salt isn’t the only way to enhance the taste of your food. You can elevate the flavor of snacks and dishes with a wide array of herbs, spices, seasonings, and lemon juice. Consider using salt-free seasoning blends to gain better control over your sodium intake.
When to Seek Help
While occasional salt cravings are normal, it’s important to seek medical advice if your cravings become persistent, intense, significantly disrupt your daily life, or are accompanied by other concerning symptoms like fatigue, nausea, and frequent urination. Significant salt cravings could potentially indicate an underlying health issue such as adrenal insufficiency (Addison’s disease), dehydration, or electrolyte imbalances.
Making high-sodium foods a regular part of your diet can lead to health complications like high blood pressure, a major risk factor for heart disease. However, enjoying your favorite salty treats in moderation is perfectly acceptable as part of a balanced diet.
