Cystic Fibrosis is the most common recessive genetic disease that is caused by the mutation of the CF transmembrane regulator that allows chloride ions to move in and out of cells to produce sweat, mucus, saliva, and digestive enzymes.  Proper nutrition that gives adequate calories and protein can help prevent the muscle wasting and malnutrition that stems from the effects of CF. In the 1980's, clinicians discovered that high-fat, high calorie diets facilitated weight gain, improved pulmonary function, and quality of life. Individuals with CF have prevalent complications dealing with gastrointestinal problems.  This is due to the altered gut microbiota that may produce potential pathogenic bacteria. Dietitians recommend twice the supplementation of probiotic and antibiotic treatment to help stabilize gut microbiota. CF patients may need 2 to 4 liters of water per day in addition to electrolyte replacement therapy. People with CF lose a lot of salt in their sweat and a high-sodium diet does not seem to affect CF patients the same as those without the disease. Lastly, the biggest goal for individuals with CF are calories, calories, calories! Nutrient dense foods will prevent CF patients with eating fatigue due to the amount of calories they have to eat to sustain their daily requirements.

Are All Sugars Created Equal?  I think one of the most confusing nutrition topics for people is sugar. With so many conflicting stories out there, it’s difficult to separate the facts from the fiction. Not to mention, the types of sugars are endless. How do we know what’s best for our bodies? White or brown sugar? Cane or raw? Should we just go with Stevia instead? Is it even okay to consume artificial sweeteners? Should we avoid foods with high amounts of natural sugar in them? Each answer only seems to lead to another question!  Let’s start off with distinguishing the purpose of sugar in the first place. Do our bodies even need it? The short answer is yes! Sugars are carbohydrates (what we commonly call “carbs”), one of the three main macronutrients that our bodies need for fuel to function and survive. One of the major ways to categorize sugar is by separating the “natural” sugars from the “added” sugars. Natural sugars are, well, naturally found in foods. They give us the energy th

Milk Mythbusters

Just like with any nutrition topic, the facts about milk can become convoluted pretty quickly. Whether you drink milk for the protein, the nutrients, the flavor, or just like to switch it up, there are pros and cons to every kind. Here are some quick nutritional facts about each type to help you decide which is best for you. Animal-Based Milks  Whole Milk: The original diary drink. It gets a bad rap, but what whole milk has going for it, is that it’s in its proper nutritional form. Whole milk contains all of its original fat-soluble vitamins, A, E, D, & K, along with the fat to help you absorb them all. It also has the proper concentrations and ratio of polyunsaturated fatty acids, or your omega-3s and omega-6s, so that they are metabolized as they should be. The downside is that whole milk is calorically dense, meaning that a little goes a long way. You don’t need much to get what you need, so just don’t overdo it!  2% Milk: The fat content of 2% milk is about half of that in who
