MNT and Prediabetes

-
Because Type 2 Diabetes Mellitus (T2DM) is one of the top ten leading causes of death in the US and it directly and indirectly causes approximately 174 billion dollars a year in the US, prevention has become a highly researched area. There have studies in the past correlating lifestyle changes in the prevention or delayed onset of T2DM in at risk populations. This specific study had the objective of determining if medical nutrition therapy (MNT) has a different effect on prevention than the usual care. 76 partiipants were used for this study, all of which had impaired fasting blood glucose or a glycated hemoglobin (HbA1C) of 5.7-6.4%. The participants were split up into two groups; one was a control group that received the usual care and the second underwent a 12 week intervention period. Data was collected pre-test and post-test to measure differences. Quantitative data collected during the study included fasting blood glucose, serum lipid levels, and a Diabetes risk score. The results demonstrated that the intervention group had significantly lower HbA1C values and diabetes risk score. Both groups demonstrated a reduction in in LDL and total cholesterol.

This research demonstrates a need for dietitians in preventative care. If dietitians are able to implement MNT on patients with prediabetes before the condition worsens, it can significantly improve the health and medical outcomes of the patient and decrease the nationwide financial burden of the disease.

Do you struggle with pre and post exercise nutrition?

What should i eat before and after a workout? First things first…carbohydrates, proteins and fats are important for the body before  and after exercise. Exercising muscle preferentially uses carbohydrates from stored glycogen, but fats are also an important fuel source for energy production during exercise. Fats and carbohydrates are the two major fuel sources during exercise. Fats must be translocated and broken down from their storage form before they are used. Typically there is enough carbohydrate stored as muscle glycogen for exercise but as muscle glycogen stores decline, the skeletal muscle will then use some amino acids (basic components of all protein). More specifically, the amino acid leucine is used for energy.              It is important to consume an adequate amount of carbohydrates exercise to delay fatigue and minimize gastrointestinal distress. It is also important to consume enough fluids to prevent hypohydration. Now, lets talk about pre-exercise me

Child Malnutrition

New approach to childhood malnutrition may reduce relapses, deaths http://www.sciencedaily.com/releases/2015/02/150211124024.htm               Moderate acute malnutrition is experienced by 35 million children worldwide. A new study led by researchers from Washington University School of Medicine in St. Louis has suggested that feeding children until they have met target measures of arm circumference and weight may be more important than a set 12 week feeding time. However, researchers have found that the current targets, set by the World Health Organization (WHO) may not be sufficient and raising these targets slightly could significantly reduce the risk of relapse in malnourished children; a condition that has a 37% relapse rate. The study took place in rural Malawi and was comprised of 2,349 moderately malnourished children aged 6 months to 5 years old. Children were evaluated 12 months after treatment; 1,967 received a soy-based supplement for 12 weeks while the other 3
