Cystic Fibrosis (CF) is a disease associated with higher energy consumption, nutritional deficiencies, and malabsorption due to pancreatic insufficiency. People with CF typically need twice the daily calories of their peers to maintain a healthy weight and fight infections. A high-calorie diet is recommended for those with CF, but it should also be well-balanced and include protein, vitamins, minerals, and essential fatty acids. Nutritional supplements can be used to boost calories, but they should not replace meals. Doctors may also prescribe pancreatic enzyme replacements to aid digestion and absorption.

Cystic fibrosis patients need extra calories to maintain a healthy weight and fight infections
Cystic fibrosis is a genetic condition that affects the body's epithelial cells, including those in the sweat glands, lungs, and pancreas. The body responds to this condition by producing thick mucus, which blocks the lungs and other passageways, leading to infections and breathing difficulties. This mucus also interferes with the normal absorption of nutrients and fat in the intestines, causing nutritional deficiencies.
Maintaining a healthy weight is crucial for cystic fibrosis patients to combat infections and keep their lungs and bodies strong. To achieve this, they often require a high-calorie diet, as they need more energy to breathe normally, fight lung infections, and compensate for poor digestion. The energy needs of people with cystic fibrosis are estimated to be 1.5 to 2 times higher than those without the condition.
A diet with 35 to 40% of total calories from fat is generally recommended for cystic fibrosis patients. This higher fat intake helps meet their increased calorie needs and is important for growth and development, especially in infants. Additionally, essential fatty acids like linoleic acid are crucial for controlling blood pressure, blood clotting, and inflammation.
To increase calorie intake, patients can add extra butter, oil, or cheese to meals, incorporate high-calorie snacks, and consume nutritional supplements alongside meals. It is important to work with a dietitian to ensure adequate nutrition without causing eating fatigue. Regular exercise is also recommended for cystic fibrosis patients.
While a high-calorie diet is important, it is also crucial to consider overall nutritional needs. Vitamins and minerals are essential for cystic fibrosis patients to build strong bones and fight infections. A multivitamin supplement may be recommended by the patient's CF team to ensure adequate vitamin intake.

![Cheese and Its Economical Uses in the Diet / by C.F. Langworthy, and Caroline L. Hunt. 1912 [Leather Bound]](https://m.media-amazon.com/images/I/617DLHXyzlL._AC_UY218_.jpg)
High-calorie foods include grilled cheese sandwiches, burritos, and full-fat yoghurt
People with cystic fibrosis may need a high-calorie diet for several reasons. The sticky mucus associated with the condition can block the absorption of nutrients and fats in the intestines, and pancreatic insufficiency can cause problems with growth and weight gain. As a result, people with cystic fibrosis may need up to twice the number of calories as their peers to maintain a healthy weight.
High-calorie foods can be a part of a healthy diet for people with cystic fibrosis. Some examples of high-calorie foods include grilled cheese sandwiches, burritos, and full-fat yoghurt. A grilled cheese sandwich made with two slices of regular bread can contain 400 calories or more, and using butter or margarine to grill the sandwich can add even more calories. A medium-sized bean, cheese, and salsa burrito is another tasty option that can help increase calorie intake.
Full-fat yoghurt is another excellent choice for boosting calorie intake. It can be enjoyed on its own or paired with granola or fruit to create a delicious and nutritious snack. For example, a nutrient-dense smoothie can be made by blending full-fat Greek yoghurt with a banana, peanut butter, and protein powder. Avocado, cottage cheese, or full-fat chocolate milk can also be added to the smoothie for even more calories.
In addition to these high-calorie foods, people with cystic fibrosis can increase their calorie intake by adding extra butter or oil to pasta, rice, potatoes, or cooked vegetables. They can also incorporate calorically dense foods such as eggs, avocado, cheese, and cream cheese into their meals. Snacking between meals and consuming high-calorie beverages such as smoothies or meal replacement shakes can further help increase calorie intake.
It is important to note that while a high-calorie diet is often recommended for people with cystic fibrosis, the focus of a healthy diet is shifting towards long-term health and disease prevention. As such, it is essential to consult with a doctor or dietitian to determine the best dietary approach for managing cystic fibrosis and maintaining a healthy weight.

Nutritional supplements can be used to boost calories, but not replace meals
People with cystic fibrosis (CF) typically need up to twice the amount of daily calories as others of a similar age and weight. This is because the sticky mucus produced by the body makes it difficult to absorb fat and nutrients. Those with CF may also burn extra calories due to frequent infections and coughing. Therefore, maintaining a healthy weight and sometimes increasing it is crucial for fighting infections and keeping the lungs and body strong.
Nutritional supplements can be used to boost calories, but they should not replace meals. Instead, they should be taken alongside meals or as a substitute for lower-calorie snacks. Supplements come in various forms, such as flavoured powders that can be mixed with milk, ready-made milk-based shakes, and high-calorie and high-protein juices. Individual fat, carbohydrate, or protein powders can also be mixed into drinks. It is important to consult with a CF dietitian to determine the most suitable supplement options.
Meal planning and preparation are essential for ensuring a well-balanced diet. Cooking larger batches and storing leftovers in the refrigerator or freezer for quick and convenient meals is a helpful strategy. Organising the kitchen with designated shelves or containers for "grab 'n' go" meals and snacks can make it easier to access nutritious options. Planning weekly menus can also reduce the stress of deciding what to eat and ensure a variety of healthy choices.
In addition to supplements, there are several ways to add extra calories to meals and snacks. For example, adding extra butter or oil to pasta, rice, potatoes, or cooked vegetables, including salad dressings or hummus with raw vegetables, and topping salads and sandwiches with avocado or guacamole. Grilling sandwiches in butter or margarine and adding a splash of cream to milk, oatmeal, smoothies, or soups are also effective ways to boost calorie intake.
It is important to note that a healthy diet for CF is not solely focused on high-calorie, high-fat, and high-salt intake. With advancements in therapies, weight gain has become more manageable, and life expectancy has increased. Therefore, the emphasis is now shifting towards considering how dietary choices can promote overall health and prevent other conditions such as heart disease or cancer. A well-balanced diet for CF should include five servings of fruits and vegetables, adequate protein, whole grains instead of refined grains, and limited sugary drinks.

Cystic fibrosis patients need to pay attention to their liquid intake, drinking 2-4 litres of water per day
People with cystic fibrosis need to pay close attention to their liquid intake to ensure they are getting enough fluids. The recommended amount is 2 to 4 litres of water per day. This is because people with cystic fibrosis lose more salt through their sweat than those without the condition and do not tend to feel thirsty in the same way. As a result, they are more prone to dehydration, especially during warmer months. Dehydration can lead to stickier mucus in the lungs and constipation, as well as common symptoms such as headaches, cramps, dizziness, and fatigue.
To avoid dehydration, cystic fibrosis patients should carry a water bottle with them and aim to drink around 2 litres of water each day, increasing this to 4 litres if they are sweating due to heat or exercise. Flavouring water with fruit, such as berries, citrus fruits, or cucumber and mint, can make it more appealing. Coconut water, fruit juice, and sports drinks are also good options for staying hydrated and replacing lost electrolytes.
It is important to note that tea, coffee, sodas, and alcohol have diuretic effects, so additional water should be consumed if drinking these beverages. In addition to water, eating salty snacks and drinking salty drinks can help cystic fibrosis patients replace lost salt and maintain proper fluid balance.
Along with adequate fluid intake, individuals with cystic fibrosis require a high-calorie, high-fat diet to meet their energy needs, which are estimated to be 1.5 to 2 times higher than those without the condition. This is because they require more energy to breathe normally, fight lung infections, and compensate for poor digestion. A dietitian can help determine the best ways to add calories to the diet and ensure adequate nutrient intake.

A diet with 40% of total calories from fat is generally recommended for cystic fibrosis patients
People with cystic fibrosis typically need up to twice the amount of daily calories as others of a similar age and weight. This is because they require more energy to breathe normally, fight lung infections, and compensate for poor digestion. The extra calories should be part of a well-balanced diet.
There are several ways to add extra fat to the diet. For example, adding extra butter or oil to pasta, rice, potatoes, or cooked vegetables, topping salads and sandwiches with avocado or guacamole, grilling sandwiches in butter, and adding a splash of cream to milk, oatmeal, smoothies, or soups. It is also recommended to focus on high-calorie snacks, such as trail mix, peanut butter and banana sandwiches, full-fat yogurt with granola, or cheese crackers.
In addition to a high-calorie, high-fat diet, it is important for cystic fibrosis patients to also include protein and salt in their diet. Protein should make up about 16-20% of calories, with two to four servings of protein-rich foods per day. Salt is essential for muscle function, digestion, and nerve cell health, and since cystic fibrosis patients have a higher concentration of salt in their sweat, they need to replace this through their diet.
It is important to note that nutritional supplements can be used to boost calories but should not be used to replace meals. Instead, they should be taken alongside meals or as a substitute for a lower-calorie snack. A dietitian with a specialty in cystic fibrosis will be able to provide specific advice and recommendations.
