Eating Well With PH

Why Good Nutrition Matters When You Have PH

Eating healthy is important for everyone — but when you have pulmonary hypertension (PH), nutrition can play a bigger role in how you feel. What you eat and drink can affect your energy, swelling, breathing, and how hard your heart has to work.

Good nutrition can help you:

Lower fluid buildup and swelling
Protect your heart and lungs
Keep up your strength and energy
Feel more stable and comfortable day to day

Eat Real Food — Less Ultra-Processed, More Natural

Try to eat foods that are fresh or frozen, like vegetables, fruits, fish, chicken, beans, and whole grains. That means fewer “ready-made” or heavily processed meals.
Note: Not all ultra-processed foods are equally unhealthy

Try to eat foods that are fresh or frozen, like vegetables, fruits, fish, chicken, beans, and whole grains. That means fewer “ready-made” or heavily processed meals.
Skip foods with lots of added sugar — like sweets, candy, soda, and sugary juices — because they add calories but little nutrition.
Think of your grocery store habits: the “outside aisles” often have healthier items (produce, meat, dairy), while processed foods tend to be down the middle aisles.
Choose nutrient-dense meals that keep you full so you don’t feel the need to snack all the time. Try to avoid late-night or overnight eating — our bodies rest and repair while we sleep, and waking to eat can interrupt that rhythm.

Watch Your Salt (Sodium) and Fluids

With PH, your body can hold on to extra fluid more easily. Too much salt or fluid can lead to swelling, weight gain, or make breathing harder.

Helpful tips:

Your PH care team may give you a daily sodium and fluid allowance — follow it closely.
Avoid “hidden salt” — many canned foods, deli meats, cheeses, olives, pickles, processed foods, and restaurant or fast-food meals have high sodium.
Limit salty snacks, processed meats, and instant meals. Use herbs, lemon, spices instead of salt to add flavor.
Count all fluids — water, drinks, soups, even ice chips or foods that melt (like ice cream or popsicles). Some PH patients may need to stay under a certain fluid amount (for example, 2 liters/day), but this is individual.
Track your weight and swelling: a gain of ~3 pounds overnight or ~5 pounds in a week may mean extra fluid. If that happens, contact your PH care team.
Read label on packages to look at the amount of sodium in a food product and keep track of how much sodium you eat and everyday

What to Eat — Heart-Healthy & PH-Friendly Choices

Here are foods that are generally more friendly for people with PH:

Lots of fruits and vegetables — fresh or frozen, many colors help you get a range of nutrients.
Whole grains — like brown rice, oatmeal, whole-grain bread, quinoa. Good source of energy and fiber.
Lean proteins — fish, skinless poultry, beans, legumes. Good protein supports muscle and overall health.
Healthy fats (in small amounts): olive oil, nuts, seeds, avocado — these support heart health without overloading salt or saturated fat.
Low-salt dairy or dairy alternatives, if you tolerate them, and if your PH Team approves.

What to limit or avoid:

Ultra-processed foods, canned foods, frozen ready-meals, deli meats, salty snacks — often high in sodium.
Heavy sauces, dressings, soups, pickles, salted nuts — all can be sodium traps.
Sugary drinks, sodas, large amounts of added sugar — low nutrition and can worsen overall health.
Overly large meals if you often have trouble breathing — smaller meals may be easier on lungs and digestion.

What are Processed versus Ultra-Processed Foods

Processed foods are foods that have been changed from their original form to make them safer, last longer, or easier to prepare.

This can include freezing, canning, cooking, or adding simple ingredients like salt or oil.

Examples of processed foods:

Frozen vegetables or fruits
Canned beans or vegetables
Yogurt
Whole grain bread

These foods can still be part of a healthy diet.

Ultra-processed foods are more heavily changed and often made in factories. They usually contain many added ingredients, like sugars, salts, fats, flavors, or preservatives. These foods are often designed to taste very good and be easy to eat quickly. Examples of ultra-processed foods:

Chips and packaged snack foods
Candy and desserts
Soda and sugary drinks
Fast food and many frozen meals

Try to eat these less often.

Tips for Meal Planning When You Have PH

Plan ahead. Try weekly meal planning. Choose one or two days to prep vegetables, lean proteins, and low-sodium meals.
Read labels carefully. Look for “low-sodium,” “no added salt,” or check the milligrams of sodium per serving.
Use herbs, lemon, spices — not salt — to flavor food.
Watch fluid intake. Keep track of all drinks and watery foods (soup, ice cream, popsicles, etc.).
Weigh yourself regularly. First thing in the morning before eating or drinking — helps spot fluid retention early.
Work with your PH team or a dietitian. Especially if you have other conditions (kidney, heart, etc.) — a dietitian can tailor a plan for you.

Common Questions (FAQ for Nutrition & PH)

Q: Do I need to cut salt completely?

A: Not necessarily — most people don’t need to eliminate all salt, but limiting salt helps avoid fluid buildup, swelling, and extra strain on your heart. Your PH team or dietitian will tell you what’s right for you.

Q: How much fluid can I drink?

A: It depends on your condition — some people with PH are asked to limit fluids to ~2 liters/day (about eight 8-oz glasses), but fluid goals are very individual. Always ask your PH care team.

Q: Will eating healthy cure PH?

A: No — healthy eating alone does not cure PH. But good nutrition helps your treatments work better, supports your heart and lungs, and can make you feel healthier and stronger day-to-day.

Q: What if I need extra vitamins or iron?

A: Nutrient needs vary. Some people with PH may need more iron, vitamin D, or other nutrients — but you should talk with your PH specialist before starting any supplements.
