Long-Term Dietary Intake and Nutritional Deficiencies following Sleeve Gastrectomy or Roux-en-Y Gastric Bypass

-

     The rate of obesity is still increasing in many parts of the world. The sleeve gastrectomy and roux-en-y procedures are two common types of gastric bypass. This type of surgery seeks to help those who are morbidly obese and have failed at diets and exercise regimens in the past. However, when part of the GI tract is being bypassed and the size of the stomach is reduced to half or less, there are going to be changes in intake and with that, nutrient deficiencies.
     Some of the most common nutrient deficiencies seen in this population and for many of those who have these gastric bypass procedures, are magnesium, phosphorous, calcium, and iron. Even those who took supplementation for these nutrients, had lower levels than recommended. This proves the importance of teaching this population how to choose the most nutrient dense foods and keeping an eye on their lab values for deficiencies.

Are All Sugars Created Equal?

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
