Ultimate Heart Transplant Diet Guide: Top Foods to Boost Recovery and Heart Health

Introduction

Heart transplantation stands as a life-saving treatment for individuals grappling with severe heart failure. Post-transplant care extends beyond the surgical procedure itself, with nutrition playing a pivotal role in the patient's recovery and long-term health. The primary goals of nutritional guidance following a heart transplant include facilitating healing, preventing infections, minimizing cardiovascular risk, and managing weight. This article aims to provide a comprehensive overview of heart transplant diet guidelines, drawing upon expert recommendations and research findings.

Nutritional Needs Immediately After Transplant

In the initial weeks following heart transplant surgery, the body requires an adequate intake of calories and protein to support healing, combat potential infections, and provide the necessary energy for recovery. During the hospital stay, a dietitian will work with you to help you make informed nutrition choices and answer nutrition questions you may have.

General Dietary Recommendations for Long-Term Health

Once the transplant starts functioning efficiently, appetite and taste perception typically improve. It is essential to prioritize nutrient-rich foods over those with limited nutritional value.

Emphasize Whole Foods

Focus on incorporating fruits, vegetables, and whole grains into the diet, rather than relying on highly processed foods.

Limit Unhealthy Fats, Cholesterol, and Sodium

Saturated fats and trans fats are found in fried foods, and snack foods such as chips, cookies, donuts, and crackers. These foods may increase your cholesterol. Cholesterol can build up in the walls of your heart and cause heart disease. Your transplant team may also ask you to limit salt as part of a healthy diet.

Maintain a Healthy Weight and Exercise Regularly

Achieving and maintaining an appropriate weight is crucial for overall health. Regular exercise, with the approval of the transplant team, should be incorporated into the lifestyle. If you are underweight, it is important to reach your ideal body weight so that you have adequate fat and protein reserves for protection during periods of infection or rejection. Excess weight can increase blood cholesterol, triglycerides, and glucose. All of these factors increase the risk of arteriosclerosis, elevated blood pressure, and possible coronary artery disease. Long-term use of prednisone can also elevate blood pressure, blood glucose, and triglyceride values. High blood glucose levels can indirectly increase blood triglyceride levels.

Food Safety Practices

Heart transplant recipients are particularly vulnerable to foodborne illnesses due to the immunosuppressive medications they must take to prevent organ rejection. Adhering to strict food safety practices is therefore essential.

Safe Food Preparation Techniques

Keep hot foods hot and cold foods cold.
Do not defrost foods on the counter; defrost them in the refrigerator.
Use separate knives and cutting boards for raw meat and other foods items.
Always wash hands thoroughly before preparing foods and between handling raw meats and other food items.
When preparing meals, it is important to wash your hands, food, and work surfaces to avoid germs. Be sure to chill food properly. Also, cook food thoroughly to kill harmful bacteria that might make you sick.

Foods to Avoid

Raw or undercooked meats, raw seafood/shellfish/sushi
Unpasteurized milk/dairy products
Unpasteurized fruit juices and ciders
Fresh (uncooked) bean sprouts/alfalfa sprouts
Beware of buffets, salad bars, and potlucks. All can be a source of food borne illness.

Potential Food-Drug Interactions

Certain foods can interfere with the effectiveness of immunosuppressant medications, necessitating their avoidance.

Grapefruit and Pomegranate

Avoid grapefruit, grapefruit juice, pomegranate, and pomegranate juice, as they can dangerously increase blood levels of immunosuppressants. Twenty-four (92%) centers mentioned food exclusions related to the introduction of immunosuppressive therapies. Thirteen different foods were prohibited.

Specific Dietary Considerations

Managing Cholesterol Levels

Evidence indicates that blood cholesterol levels are influenced by the amount of dietary cholesterol, saturated fats, and total fats consumed. Even if blood cholesterol levels are within the normal range and there is no prior history of coronary artery disease, following a dietary fat modification is advisable. Whether cholesterol deposition plays nearly as important a role in transplant coronary artery disease is an unanswered question, but it seems prudent to try to control cholesterol levels. This includes limiting egg yolk, high-fat dairy foods and meats, and selecting non-fat milk, lean cuts of red meat, poultry, and fish.

Sodium Intake

To avoid fluid retention and aid in the control of high blood pressure, a no-added salt diet is generally recommended. This entails lightly salting food during cooking but refraining from adding salt at the table. Nineteen centers (73%) advised to control salt intake with widely varying advice ranging from 2 to 8 g per day. Eight centers (31%) recommended salt restriction without quantitative benchmarks.

Limiting Simple Carbohydrate Intake

Limit simple carbohydrate intake. The topic of carbohydrates focused primarily on a reduction in sweet products (n = 20, 77%), limiting fruits (n = 12, 46%), and regulating complex carbohydrates (n = 8, 31%).

Protein Intake

For protein intake, the centers suggested one to two portions of protein per day (n = 8, 31%). You may have fewer dietary restrictions than you did before your transplant.

Lifestyle Recommendations

Sports and Recreation Safety

In general, athletic activities are safe and encouraged for transplant recipients, but pay attention to what is considered safe and what is not safe:

Safer activities include:RunningBasketballSwimming (swimming in salt water is safer than swimming in fresh water, such as lakes or rivers)VolleyballAerobicsSkatingTennisCyclingSoccerGolfCanoeingWeightlifting (low weight with high repetition)

Less safe activities have a higher chance of physical injury, such as:FootballKarate and martial artsIce hockeyTrampolinesBoxingDodge ballGymnasticsATV/snowmobilingDownhill skiing or snowboardingSleddingPower lifting (high weight with low repetition)Horseback riding

For activities outside with a lot of sun exposure, it is important to protect your skin, because transplant recipients have a higher chance of skin cancer, such as:Wear sunscreen of SPF30 or higherAvoid the sun during peak hours from 10am - 4pmAvoid tanning beds

Ask your transplant team when it’s safe to restart your pre-transplant activities.

Animal Contact and Pet Safety

Having pets is wonderful for our mental health. However, transplant recipients must be careful with pets, because they have a higher chance of getting infections from animals.

Here are some guidelines for certain animals:In general, dogs and cats are safe, but they must be up-to-date with their own healthcare, such as their shots. If you have a cat, avoid changing the kitty litter. If that is not possible, change the litter daily and wear gloves and a mask.

Avoid certain pets due to the higher chance of infection:Rodents, such as guinea pigs or hamstersReptiles, such as lizards, snakes, or turtlesAmphibians, such as frogs or salamandersBirds, such as parrots, parakeets, or finches

Here are some tips for animal safety:Wash your hands carefully after handling petsDo not let your pet lick your wounds or chew on your IV tubingAvoid handling pets with diarrheaAvoid animal bites and scratches and do not pet stray animalsEnsure your home is free of raccoon latrines. These are areas where raccoons repeatedly go to the bathroom, which may include decks, patios, attics, or garages.

If you work with animals, such as a veterinarian, pet store employee, farmer, or slaughterhouse or laboratory worker, avoid work for 6 months after your transplant.

Gardening Safety

Soil has many fungi and molds that can cause infections. You should avoid gardening for the first 6-12 months after your transplant. Ask your doctor when it’s safe to work in the soil again.

Here are a few tips to protect yourself when it’s safe for you to garden again:Wear glovesCover your skin with clothingWear a maskUse bug spray (and put it on last, after you’re dressed)Check yourself for ticks

Travel Safety

Discuss your travel plans with your transplant team at least 2 months in advance so they have time to review your plans for safety. You may also want to meet with a travel specialist who works with transplant recipients. It is generally not recommended for transplant recipients to travel to:Developing countriesAny place that requires vaccine for entrance

If you are traveling to the developing world:Water is often not safe to drink, so use only bottled water even for brushing your teethDo not use ice as it likely comes from the local water systemFollow the rule: “boil it, cook it, peel it, or forget it”Never get the yellow fever vaccine because it is a live vaccine. Live vaccines contain a weakened version of the germ it is trying to protect you from. Because of this, there is a small chance the vaccine can cause an infection.

Here are some tips for safe travel:Bring an extra supply of your medicineKeep all medicine in your carry-on bagBring a note from your doctor explaining what each medicine is forHave a plan for leaving in case you get sick or have a medical emergencyHave a plan in case you get diarrhea, because being dehydrated from diarrhea can affect the levels of your immunosuppressive drugs

Substances

After a kidney transplant:Alcohol may be safe in moderation, but talk with your transplant centerNot much is known about marijuana safety, but keep in mind:It can cause mental impairment, dangerous drug interactions, kidney injury, abnormal heart rhythms, and infections from moldsIt is safer to eat an edible baked at 300 degrees rather than smokedIt may affect your anti-rejection drug levelsAvoid smoking tobacco because it can lower blood flow to your kidneys and cause your kidneys to not work as well

Keeping a Healthy Weight

Keeping a healthy weight after your transplant can be hard because some of your medicines, such as steroids, can cause weight gain. Gaining weight can hurt your heart and bone health. Here are some tips for keeping a healthy weight:Eat a healthy diet low in saturated fats and cholesterol, low in trans-fat, and high in fiberLimit alcohol. Alcohol has hidden calories and can make you hungry and eat more.Drink plenty of water (unless you are on a fluid restriction)Follow a low sodium dietAvoid dietary supplements as they can cause dangerous drug interactions, liver and kidney damage, and probiotics can cause infections

Safer Sex Practices

The best way to lower your chance of sexually transmitted infections (STIs) is to have fewer sexual partners or be in a long-term relationship with 1 person (monogamous).

Here are some ways to lower your chance of infection and STIs during sex:Always use latex condoms during sexual contact outside of monogamous relationshipsConsider latex condoms in monogamous relationships for the first 6 months after the transplantAvoid exposure to feces during sexual activitySome medicines can affect sexual arousal and performance. Discuss these issues with your transplant physician if they happen.

Having Children

Many people have had children after a transplant. However, female transplant recipients do have a higher chance of problems during and after pregnancy. Always discuss plans for having children with your transplant team. All females who have a transplant should see a high-risk obstetrician. Doctors recommend:Waiting at least 1 year after surgery to become pregnant, until the kidney is stable and without episodes of rejectionUsing contraception early after transplant surgeryUsing long-term contraceptives such as intrauterine device (IUD) and subdermal implants

If you become pregnant, you will need to tell your transplant and obstetrical team right away. Some medicines are not safe for the baby during pregnancy. Your doctors will need to closely monitor your health throughout your pregnancy and after delivery.

Vaccines

Vaccines are an important way to protect you and your family. Before your transplant, get any vaccines that need to be updated. Your vaccines will work better before your transplant. And make sure everyone in your household is also updated on their vaccines. Soon after your transplant, you may not be able to get some vaccines, except for your yearly flu shot and pneumococcal vaccines. Avoid live vaccines, which include MMR, varicella, rotavirus, yellow fever, and the intranasal flu vaccine. Live vaccines can sometimes carry infections. If you learn that someone you have been in close contact with recently got a live vaccine, contact your transplant team.

Whenever you are deciding to get a vaccine, remind your doctor or pharmacist that you are a transplant recipient.

Oral Health

Good dental health can help prevent infections, while sore and bleeding gums can cause infections. Some of your medicines and a poor diet can cause swollen, sore gums and teeth sensitivity. Here are ways to keep your mouth and teeth healthy:Examine your gums and teeth dailyBrush after each meal with a soft toothbrush and fluorinated toothpasteFloss dailyMake sure any dentures have a proper fitHave your teeth cleaned and checked by a dentist every 6 monthsAlways tell your dentist that you are a transplant recipient before having any cleanings or procedures done

Vision Care

Some of your medicines, such as prednisone, can cause problems such as cataracts or dry eyes. Eye symptoms can be a sign of an infection starting. If you have any eye symptoms, let your transplant team know right away. See an ophthalmologist (eye doctor) regularly for dilated, cataract, and glaucoma eye exams.

Mental Health

Getting a transplant is a major life change and it is normal to have all kinds of feelings after a transplant. While some people may be overjoyed, some people may feel overwhelmed and stressed by the medicines and doctors’ visits. Some people may have health problems after their transplant, which can lead to depression. Other people may feel anxiety while trying to keep themselves healthy.

If you ever need emotional support, seek a professional to help you process your feelings and help you cope with your new normal.

Variability in Nutritional Advice

A study analyzing nutritional recommendations across 26 heart transplant centers in French-speaking Europe revealed significant variability in the advice provided. This highlights the absence of standardized guidelines and the need for a consensus-based approach to nutritional care following heart transplantation. While some recommendations, such as avoiding grapefruit and raw foods, were consistently shared, others differed considerably, reflecting diverse clinical practices and approaches. This variability underscores the need for standardizing nutritional advice to ensure consistent and optimal patient care in the post-transplantation period.

The Role of Dietitians

The presence of a dedicated dietitian significantly impacts the quality of nutritional guidance provided to heart transplant patients. Centers with a dietician are more likely to offer comprehensive and tailored advice, emphasizing the importance of integrating dietitians into the transplant team. Only one center did not have a dietician, and, notably, this was the same center that provided no written advice.
