Pulse starches generally have a higher content of amylose compared with cereal and tuber starches; this factor plus their associated high capacity for retrogradation may reduce
the starch digestion rate, rendering them either slowly digestible and / or resistant to digestion.
Not exact matches
A lower glycemic index suggests slower
rates of
digestion and absorption of the sugars and
starches in the foods and may also indicate greater extraction from the liver and periphery of the products of carbohydrate
digestion.
When consumed with other food (especially fats), the
rate of
digestion and absorption of
starches slows down and you don't experience blood sugar spikes, so it doesn't really matter if the rice you ate was white or brown.
Considering these data together with those of MacNeil, it's likely that potato
starch doesn't impact blood glucose levels because
digestion of the digestible portion occurs at such a low
rate that glucose absorption is easily matched by glucose clearance.
The ability of
starch to raise blood glucose levels after a meal (glycemic index) in individuals with diabetes mellitus depends mainly on the
rate of
starch digestion and therefore on the type of starchy food [1].
Potato
starch characteristics play a key role in determining their
rate of
digestion and resulting glycemic response.The Glycaemic Index (GI) status of Carisma potatoes was established in a joint project between Sydney University and the Mitolo Group.
Phytate has been shown to reduce the in vitro
rate of
starch digestion and delay postprandial glucose absorption in humans (52), which could contribute to satiety and delay the return of hunger, as discussed below.
The basis for the moderated
digestion rate of pulse
starches remains rather unclear.
