What Foods Can You Eat To Raise Your Blood Pressure?

Most food advice focuses on lowering blood pressure. But some people — those with orthostatic hypotension, certain chronic conditions, or older adults prone to dizziness — are told by a clinician to raise theirs. The foods that can help do this are those high in sodium, foods that are salted or cured, and licorice. Caffeine can cause a short-term rise. The effect of any single food is modest, and eating to raise blood pressure should only be done with medical guidance.

This is not a do-it-yourself project. Low blood pressure that causes symptoms is a medical issue, and the cause matters enormously. What follows is what the evidence actually shows about food and blood pressure — including where the evidence is thinner than most articles admit.

Why Would Someone Need to Raise Their Blood Pressure?

Low blood pressure is only a problem when it causes symptoms or when the brain and organs aren’t getting enough blood flow.

A blood pressure reading below 90/60 mmHg is generally considered low. Many healthy people live at that level with no issues at all. The number alone doesn’t define a problem — symptoms do. Lightheadedness when standing, fainting, blurred vision, fatigue, trouble concentrating, and nausea are the signals that matter.

The most common form is orthostatic hypotension — a drop in blood pressure when you stand up. Clinically, this is defined as a fall of at least 20 mmHg in systolic pressure or 10 mmHg in diastolic pressure within three minutes of standing. It’s more common in older adults, in people taking certain blood pressure medications, and in some neurological conditions.

Other causes include dehydration, prolonged bed rest, heart conditions, endocrine disorders, and pregnancy. Some people have low blood pressure after eating a large meal — a phenomenon called postprandial hypotension.

If you have any of these symptoms, the first step is a diagnosis. Food strategies come after that, not before.

What Foods Can You Eat To Raise Your Blood Pressure?

Sodium is the most reliable dietary lever for raising blood pressure, and it’s the one clinicians most often discuss. Salt pulls water into the bloodstream, which increases blood volume and, in turn, pressure.

The relationship between sodium and blood pressure is well established in the other direction — cutting sodium lowers pressure in many people. The reverse also holds. Increasing sodium intake raises blood pressure in most people, though the size of the effect varies a lot between individuals. People who are “salt-sensitive” respond more strongly. Older adults and people with certain conditions tend to be more salt-sensitive than young, healthy adults.

Foods that deliver meaningful sodium include:

• Salted nuts and seeds
• Cheese, especially hard aged cheeses
• Cured and salted meats such as ham, bacon, and salami
• Pickled foods such as pickles, sauerkraut, and olives
• Canned soups, broths, and stock
• Soy sauce and other salty condiments
• Salty crackers and pretzels
• Smoked fish

How much sodium is enough to raise blood pressure is not something you can work out on your own. The amount depends on your diagnosis, your current intake, your kidney function, and other factors. This is a conversation to have with a clinician — not a number to pick from an article.

Can Drinking More Water and Fluids Help?

Increasing fluid intake can raise blood pressure by expanding blood volume. This is a standard part of managing some forms of low blood pressure, particularly when dehydration is a factor.

Rapidly drinking a large amount of water — sometimes called a water bolus — has been studied as a way to raise blood pressure quickly in people with autonomic dysfunction. The effect appears within minutes and can last for a while. This is a strategy some clinicians recommend for specific patients, not a general recommendation.

Electrolyte drinks containing sodium can serve double duty: fluid plus salt. For people who are not on sodium-restricted diets, these can be a practical option.

One caution: drinking large volumes of fluid is not safe for everyone. People with heart failure or kidney disease may be told to limit fluids. Again, this depends on the individual.

Does Caffeine Raise Blood Pressure?

Caffeine causes a short-term rise in blood pressure in many people. It blocks a hormone called adenosine, which normally helps blood vessels relax. With adenosine blocked, vessels narrow and pressure goes up.

For people who don’t drink coffee regularly, a cup can produce a noticeable temporary bump. For habitual coffee drinkers, the effect tends to be smaller because the body adapts. The rise is usually modest and temporary — it is not a treatment for chronic low blood pressure.

Coffee, tea, and energy drinks all contain caffeine. Energy drinks are a different category. They often combine caffeine with other stimulants, and their effects on heart rate and blood pressure can be stronger and less predictable. They are not a good tool for managing blood pressure.

Does Licorice Really Raise Blood Pressure?

Yes — and this is one of the more important and less well-known food effects on blood pressure. Real black licorice contains a compound called glycyrrhizin, which blocks an enzyme that normally converts cortisol into an inactive form. The result is a cortisol-like effect that causes the body to retain sodium and lose potassium. Blood pressure can rise substantially.

This is not a mild or theoretical effect. Cases of serious high blood pressure, low potassium, and heart rhythm problems have been documented in people who ate large amounts of black licorice regularly. The FDA has warned about this. Many licorice candies sold in the US now use artificial flavoring instead of real licorice root, so they don’t carry this effect — check the ingredient list for licorice extract or glycyrrhizin.

Licorice is not a sensible way to raise blood pressure. The effect is real but the risks — including potassium loss and heart rhythm disturbance — are significant. It’s included here because people deserve to know it exists, not because it’s a good strategy.

What About Small, Frequent Meals?

For people whose blood pressure drops after eating, eating smaller meals more often can help. Large meals divert more blood to the digestive system, which can cause a dip in blood pressure — particularly in older adults.

This is a well-recognized phenomenon, though the evidence for how best to manage it comes more from clinical experience than from large trials. Some clinicians recommend smaller, more frequent meals, limiting alcohol with meals, and lying down or sitting quietly after eating for those prone to symptoms.

Alcohol is worth mentioning separately. It can lower blood pressure, particularly in the hours after drinking, and it contributes to dehydration. For someone trying to raise their blood pressure, alcohol works against the goal.

What Should You Be Careful About?

Eating to raise blood pressure is the opposite of standard dietary advice, and that makes it something to approach with care.

Raising sodium intake is not harmless. High sodium intake over time is associated with increased risk of high blood pressure, stroke, and heart disease in the general population. For someone with a genuine need to raise blood pressure, a clinician may judge the short-term benefit worth it — but this is a risk-benefit calculation that belongs with a doctor, not a food blog.

People with heart failure, kidney disease, or a history of high blood pressure need particular caution. Adding salt without guidance can be genuinely dangerous for them.

It’s also worth knowing that food alone is rarely the main treatment for symptomatic low blood pressure. Clinicians often use other approaches first or alongside diet — compression stockings, changing how you stand up, raising the head of the bed, and in some cases medication. Diet is one piece, not the whole picture.

The most useful thing you can do is get an accurate diagnosis. Low blood pressure has many causes, and the right approach depends entirely on which one applies to you.
