Registered dietitians play essential role in effective management of diabetes in adults

ADA nutrition guidelines provide evidence-based framework for nutrition professionals

Proper nutrition therapy is essential for the successful management of type 1 and type 2 diabetes and registered dietitians (RDs) can play a key role as part of the health care team.

An article in the December issue of the Journal of the American Dietetic Association reviews the evidence and nutrition practice recommendations presented in the American Dietetic Association Nutrition Practice Guidelines for Type 1 and Type 2 Diabetes in Adults. This complete and systematic review presents 29 key nutrition practice guidelines in order to best support people with diabetes.

According to Marion J Franz, MS, RD, lead author and noted nutrition consultant, "This publication has reviewed the process for developing the guidelines, identified major and contributing factors for diabetes nutrition therapy, reviewed and summarized research, and stated the nutrition practice recommendations that are to be integrated into the nutrition care process. The nutrition practice guidelines provide recommendations for assessing client/patient needs and for selecting interventions, monitoring and evaluating outcomes. The evidence is strong that medical nutrition therapy provided by RDs is an effective and essential therapy in the management of diabetes. RDs are uniquely skilled in this process."

The authors conducted a thorough review of the research literature to distill evidence-based nutrition recommendations and practice guidelines regarding the major nutrition therapy factors – carbohydrates (intake, sucrose, non-nutritive sweeteners, glycemic index, fiber), protein intake, cardiovascular disease, and weight management. Armed with information regarding what works and why, RDs can encourage lifestyle changes and select appropriate interventions based on key recommendations that include consistency in day-to-day carbohydrate intake, adjusting insulin doses to match carbohydrate intake, substitution of sucrose-containing foods, usual protein intake, cardioprotective nutrition interventions, weight management strategies, regular physical activity, and use of self-monitored blood glucose data.

Key recommendations:

Consistency in day-to-day carbohydrate intake for persons with type 2 diabetes

Adjusting insulin dose to match carbohydrate intake for persons with type 1 diabetes
Focusing on total carbohydrate intake rather than the type of carbohydrate

Cardio protective nutrition interventions
Weight management strategies
Regular physical activity
Use of self glucose monitoring data to determine if goals are being met
The article is "The Evidence for Medical Nutrition Therapy for Type 1 and Type 2 Diabetes in Adults" by Marion J Franz, MS, RD; Margaret A Powers, PhD, RD; Carolyn Leontos, MS, RD; Lea Ann Holzmeister, RD; Karmeen Kulkarni, MS, RD; Arlene Monk, RD; Naomi Wedel, MS, RD; and Erica Gradwell, MS, RD. It appears in the Journal of the American Dietetic Association, Volume 110 Issue 12 (December 2010) published by Elsevier.

In an accompanying podcast interview lead author Marion J Franz, MS, RD, and Kari Kren, MPH, RD, LD, Manager, Evidence-based Practice, Research & Strategic Business Development, ADA, discuss the importance and implications of "The Evidence for Medical Nutrition Therapy for Type 1 and Type 2 Diabetes in Adults."

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
