Dietary Treatments

 People with cystic fibrosis tend to be malnourished and underweight because their mucus keeps intestines from absorbing fat and vitamins. As a result, they require a diet high in fat and calories along with nutritious items and dietary supplements. It is recommended that teens with cystic fibrosis eat 2,900-4,500 calories every day. The problem is that thick mucous in the lungs may impair breathing and make it harder for CF patients to eat. 
                --> Thus, they should focus on foods that are fat and calorie dense in order to meet their unique nutritional needs. 

 
 Fish, nuts, beans, cheese, and eggs are all great sources of calorie-dense foods that are rich in healthy fats.

CF patients also require a greater amount of protein, iron, salt, zinc, and calcium than a healthy person would. 
             Protein: 15-20% of diet
                                               Sources: meat, eggs, soy foods, fish, nuts, beans
             Iron: fights infection, carries oxygen to tissues through the blood.
                                               Sources: fortified cereals, meats, dried fruits, dark green vegetables
             Salt: CF patients lose a lot through sweat.
                                               Sources: add salt to food, eat salty snacks, sports drinks after exercise
             Zinc: promotes growth, healing, and fighting infection
                                               Sources: meat, liver, eggs, seafood
             Calcium: CF increases risk of osteoporosis
                                               Sources: dairy products - full fat dairy products are also good source of  fat and calories
