Default Waxy Maize Studies

A lot of people have been asking about waxy maize.

Does anyone have full access to these studies? I don't from my current location..

Default Re: Waxy Maize Studies

Found the abstract for the 2nd one:

http://www.ncbi.nlm.nih.gov/pubmed/1...t=AbstractPlus

It seems this study found that the waxy maize ( amylose / C-Drink ) emptied from the stomach faster than the dextrose/glucose drink with no difference in plasma insulin/sugar levels!!

[ QUOTE ]
The energy density of a nutrient drink is one of the main factors that affect the gastric emptying of the solution, while osmolality and viscosity are thought to have only a minimal influence. Method: The rate of gastric emptying of two isoenergetic carbohydrate solutions with different osmolality and viscosity was determined using a double sampling gastric aspiration technique. Six healthy male subjects were studied on two occasions using approximately 550 ml of a solution containing 13.5% of carbohydrate either in the form of a mixture of monomeric glucose and short chain glucose oligomers (G-drink) or of long chain glucose polymers composed of 78% amylopectin and 22% amylose (C-drink). Result: The half emptying time (t[1/2], median and range) for the viscous, markedly hypotonic (62 mosmol/ kg) C-drink was faster (17.0(6.2-31.4) min) than for the moderately hypertonic (336 mosmol/kg) G-drink (32.6 (25.2-40.7) min). The amount (median and range) of carbohydrate delivered to the small intestine was greater during the first 10 min after ingestion of C-drink (31.8 (15.8-55.9) g) than after ingestion of G-drink (14.3 (6.8-22.2) g). However, there was no difference in the blood glucose (P=0.73) or serum insulin (P=0.38) concentration at any time point after ingestion of the two test drinks. Conclusion: The results of this study show that the carbohydrate present in C-drink, although it has the propensity to form a gel, empties from the stomach faster than that of an isoenergetic carbohydrate solution (G-drink) without potentiating increased circulating blood glucose or insulin levels.

I still can't find a link for the 1st study or the full text for the 2nd.
