Outcomes

Primary Outcome Measures

blood glucose
Glycaemic response will be measured before the treatment (baseline) and at 15, 30, 45, 60, 90 and 120 min after the treatment. The glucose concentration will be measured in capillary blood using portable glucose meter.

Secondary Outcome Measures

food intake
Ad libidum food intake will be measure at 120 min using test pizza meal. The amount of consumed test meal (g) will be converted to the energy (kcal).

Brief Summary
Potato is one of the world's most popular foods and is widely accepted as a staple food. The objective of this study is to determine the effect of altering commercial blanching and cooling times during manufacture of frozen fries produced by the on blood glucose, satiety and appetite. It hypothesized that the processing regime predetermines the physiologic responses to ingested product and therefore it is possible to produce healthier product lines of potato fries.
