Gut Training Flashcards
A high carbohydrate diet will increase the density and activity of what transporter
This increase results in what
Sodium dependent glucose transporter 1
Greater carbohydrate absorption and oxidation
Does the mechanism of action differ for upper and lower GI problems
Yes
Saturation of ________ transporter will prevent increases in glucose absorption
SGLT1
The rate limiting factor of carbohydrate oxidation (skeletal muscle) is the ______________ ___________ __ _____________
Intestinal absorption of carbohydrate
Symptoms of GI issues are more likely to be exacerbated in what two conditions
Hot weather
Dehydration
What 2 non-nutritive sweeteners increase SGLT1 expression
Acesulfame K
Saccharin
What luminal transporter assists glucose OR fructose
Glucose: SGLT1
Fructose: GLUT5
T/F
A high carbohydrate diet can increase SGLT1 protein and transport capacity for glucose
True
Why would a hydrogen breath test be used
Measure carbohydrate absorption
High: malabsorption
Low: good absorption
What organs are the main targets of gut training
Stomach
Intestine
Which organ, stomach or intestine, has faster adaptations without training
Stomach
How many different tests are used to populate the gut training score
5
What mechanism is fructose ingestion associated with in regards to negative gut issues
Associated with increased small intestinal water content resulting in GI symptom induction
Causes exercise induced gastrointestinal syndrome
Splanchnic hypoperfusion
Intestinal epithelial injury
Increased intestinal permeability
Systemic responses (endotoxaemia, cytokinaemia)
Impaired intestinal nutrient absorption
Stress induced increases in sympathetic drive and reductions in enteric nervous system activity which alters intestinal motility and absorption capacity
What marker is used to assess intestinal injury
Intestinal Fatty Acid Binding Protein (I-FABP)
