Congestive heart failure (CHF) occurs when the heart is unable to pump blood efficiently, leading to a build-up of fluid in the body. This condition can result in symptoms like shortness of breath, swelling, and fatigue. Treatment for CHF focuses on slowing its progression and relieving symptoms by reducing the workload on the heart. Dietary changes play a crucial role in managing CHF, primarily by decreasing fluid retention and maintaining healthy potassium levels. A low-sodium diet is often recommended, as sodium contributes to water retention, making the heart work harder. This involves limiting salt intake during cooking and at the table, being mindful of sodium content in packaged and processed foods, and opting for fresh, low-sodium options. Physical activity, a balanced diet, and avoiding smoking are also essential components of a heart-healthy lifestyle.

What You'll Learn
Reduce sodium intake
A low-sodium diet is crucial for managing congestive heart failure (CHF) and improving overall heart health. Here are some essential tips to reduce sodium intake:
Understand the Impact of Sodium
Sodium contributes to water retention in the body. When you consume too much salt, your tissues retain more water, acting like a sponge. This extra fluid puts an additional burden on your heart, making it work harder to pump blood effectively. Therefore, reducing sodium intake is a crucial step in managing CHF.
Monitor Your Sodium Intake
It is essential to become aware of the sodium content in the foods you consume. Reading food labels is a helpful way to keep track of your sodium intake. Check the serving size and the sodium count in milligrams per serving. As a general rule, avoid foods with more than 500 mg of sodium per serving. Additionally, be cautious if salt or sodium is listed as one of the first five ingredients on a food label.
Reduce Salt in Your Cooking and at the Table
A simple way to reduce sodium is to avoid adding salt to your food during cooking or at the dining table. Instead of salt, experiment with other flavour enhancers. Fresh or dried herbs, onions, garlic, citrus juices, and spices like curry, ginger, and pepper can add a burst of flavour to your dishes without the sodium. You can also create your own salt-free seasoning blends or purchase premade ones. Over time, your taste buds will adjust to this reduced-sodium diet, and you will crave less salt.
Be Mindful When Eating Out
Restaurant and fast food meals can be significant sources of hidden sodium. When dining out, be cautious of menu terms that may indicate a high sodium content, such as "pickled," "au jus," "soy sauce," and "broth." Opt for fresh fish, beef, or vegetables instead of processed or cured meats. Ask for sauces and salad dressings on the side, as these often contain high levels of sodium.
Choose Low-Sodium Foods
When shopping for groceries, opt for low-sodium or sodium-free options. Choose unsalted fresh, frozen, or canned vegetables and fruits. Look for milk and dairy products with reduced fat and sodium, such as low-fat milk (2% or 1%) or skim milk. Select whole grains, unsalted crackers, and sandwich bread. Remember that processed and packaged foods tend to be high in sodium, so always check the labels.

Limit fluids
For patients with congestive heart failure, the heart struggles to manage fluid levels, which can build up in the body. This can cause shortness of breath, swelling in the abdomen or legs, and fatigue. As such, it is important to limit fluids and reduce water retention.
Firstly, it is crucial to monitor your weight, as this can be an indicator of excess fluid in the body. Weigh yourself every morning, at the same time, on the same scale, wearing similar clothing. If your weight increases by 1-1.5 kg in a day, or 2 kg in a week, contact your healthcare provider. You may also notice that your clothes and shoes feel tighter than normal.
To reduce fluid retention, it is essential to limit your sodium intake. Sodium causes your tissues to retain water, which can worsen the symptoms of congestive heart failure. The American Heart Association recommends 2,000 to 3,000 milligrams of sodium per day for heart failure patients. This is significantly lower than the average American's sodium intake. To limit sodium, avoid adding salt to your food, and be cautious when eating out, as restaurant and fast food often contain high levels of sodium. Learn to recognise high-sodium menu terms, such as pickled, au jus, soy sauce, and broth. Opt for fresh, unprocessed foods, such as raw vegetables, fresh fish, beef, and fruits. Check food labels and avoid anything with over 500 milligrams of sodium per serving.
In addition to dietary changes, light exercise can help to manage congestive heart failure. Activities such as brisk walking or riding a stationary bicycle can help to maintain and strengthen the heart.

Maintain healthy potassium levels
Maintaining healthy potassium levels is crucial for people with heart failure. Potassium helps balance fluids in the body and supports the proper functioning of the heart. Certain heart failure medications can cause a drop in potassium levels, which can lead to very rapid heart rhythms and potentially result in sudden death. Therefore, it is essential to include potassium-rich foods in your diet.
Some foods that are rich in potassium include:
- Fruits such as bananas, apricots, cantaloupe, honeydew melon, and oranges.
- Vegetables like spinach, broccoli, potatoes, sweet potatoes, and mushrooms.
- Legumes, including kidney beans, lima beans, and lentils.
- Dairy products such as milk and yoghurt.
- Nuts and seeds, particularly pistachios, almonds, and pumpkin seeds.
When incorporating these foods into your diet, it is important to monitor your potassium intake. Excessive potassium consumption can also be harmful, so it is best to consult with a healthcare professional to determine the appropriate amount for your specific needs.
In addition to dietary sources, potassium supplements may be recommended by your doctor if your levels are particularly low. However, it is crucial to only take supplements under medical supervision to avoid any potential complications.
It is worth noting that certain factors can affect potassium levels in the body. For example, excessive sweating, vomiting, or diarrhoea can lead to potassium loss. Additionally, certain medications or medical conditions may impact potassium levels. Therefore, it is advisable to discuss any concerns with your doctor and have your potassium levels checked regularly.

Avoid salt
A low-sodium diet is crucial for managing congestive heart failure (CHF). This is because sodium causes the body's tissues to retain water, making the heart work harder to pump blood efficiently. Therefore, reducing salt intake is essential to alleviate the symptoms of CHF.
The recommended sodium intake for heart failure patients is 2,000 to 3,000 milligrams per day. However, it is important to note that one teaspoon of table salt already contains over 2,000 milligrams of sodium. Thus, it is crucial to be mindful of the amount of salt added to meals during cooking or at the table. It is advisable to use herbs, spices, and citrus juices to enhance the flavour of food instead of salt. Additionally, when dining out, it is recommended to avoid adding salt to meals and opt for fresh foods, as restaurant and fast food meals tend to be high in sodium.
Reading food labels is essential to monitor sodium intake, as packaged, canned, and processed foods often contain high levels of sodium. It is best to avoid foods with salt or sodium listed among the first five ingredients. Additionally, certain terms on menus or food labels can indicate a high sodium content, such as "pickled", "au jus", "soy sauce", and "broth". It is also important to note that bacon, cheese, and condiments like mustard, ketchup, and pickles are high in sodium.
When cooking at home, opt for fresh, frozen, or canned foods with no added salt. Fruits, vegetables, whole grains, legumes, and nuts are excellent choices for a heart-healthy diet. These foods are packed with nutrients, fibre, and plant compounds that promote heart health. Additionally, choosing fish high in omega-3 fatty acids, such as salmon, sardines, and albacore tuna, can help lower blood pressure and reduce the risk of cardiac issues.
In summary, reducing salt intake is crucial for managing CHF. This involves monitoring sodium levels in packaged and restaurant foods, using alternatives to salt for flavour, and opting for fresh, low-sodium options. By making these dietary changes, individuals with CHF can effectively support their treatment and improve their overall heart health.

Eat fruits and vegetables
Eating plenty of fruits and vegetables is a cornerstone of a heart-healthy diet. They are high in nutrients, low in calories and naturally low in salt. The more colourful your plate, the better.
Fruits and vegetables are excellent sources of fibre, which lowers levels of artery-clogging cholesterol. Fibre also digests slowly, keeping you full for longer and helping to curb your appetite. Green vegetables like spinach, kale and broccoli are good sources of vitamins C and E, and folate. Orange fruits and vegetables like carrots, sweet potatoes and cantaloupe are rich in beta-carotene and fibre. Berries are packed with fibre and plant nutrients.
Dried, fresh, frozen or low-sodium canned fruits and vegetables are all good options. However, it's best to avoid canned fruit in heavy syrup or any fruits with high fructose corn syrup. If you're buying canned beans, choose salt-free options or rinse them to cut down on the sodium content.
It's important to note that people with heart failure also need to maintain healthy potassium levels, which can drop due to certain heart failure medications. Lack of potassium can lead to very rapid heart rhythms that could result in sudden death. Some potassium-rich foods include vegetables like spinach, broccoli, potatoes and mushrooms, and fruits like bananas, apricots and oranges.
