Slow-Releasing
Carbs
For Weight Loss
by

Here
are four simple components to look for when choosing an ideal slow-releasing
carbohydrate.
Digestive
Surface Area Most supermarket breads are absorbed too quickly into our
digestive system. When grain is pulverized by our modern high speed rolling
mills into a talcum powder, the surface area available for immediate digestion
is dramatically increased, resulting in a blood glucose spike.
The soft
pillowy bread that we have all grown accustomed to will cause a glucose spike
higher than white sugar. The way they are able to achieve such unnaturally
fluffy bread is by adding gluten, a sticky protein, to the flour. We are going
to discuss gluten in more detail a little later. Gluten provides the dough with
an elastic strength, so when yeast is added, the bread will rise without
breaking small bubbles produced by the active yeast, again vastly increasing the
digestive surface area. If it melts in the mouth, be sure it will hit the blood
like a Mack truck. This also applies to puffed grains, like puffed wheat or Rice
Krispies, which are high on the glycemic index.
Whole grains,
on the other hand, are slow to break down into glucose, providing a more
sustained energy. I have learned to enjoy heavier, chewy breads with whole
seeds, raisins and cracked grains, such as whole grain rye, muesli, multigrain
and pumpernickel. They are filling, releasing energy slowly, and when toasted
and topped with natural peanut butter, it’s a real treat two hours before
hitting the gym. The reward is a great workout.
Cooking pasta
only until chewy, or as the Italians say, al dente, will also
significantly lower GI—better yet, choose whole-wheat pasta.
Fiber
Moderator Fiber acts as a physical barrier to digestion, helping to slow
down the assimilation of starch. The fiber which coats beans and seeds is a
moderating factor, restricting the digestion of starches for fuel, making them
low-GI foods. Beans, some grains and whole oats contain soluble fiber, making
intestinal contents more viscous and slowing the absorption of starch.
Amylopectin And Amylose Starches Amylopectin and amylose are the two
principal plant starches, and both release energy differently. Indian rice has a
different starch than Chinese rice, converting more slowly into metabolic fuel.
Amylopectin, found in Chinese rice, is much easier to digest due to its
structural differences, its branches offering a greater surface area for enzymes
to work. Amylose, the starch common to basmati Indian rice, is preferable for is
slower release. This is largely ignored by the so-called Low-Carb Diets, lumping
all rice together under a “must stay away” food.
Combining
Fat in Food Fat slows down the rate of emptying the stomach, hence
oatmeal cookies have a lower GI then plan oatmeal. But adding fat to starches is
not the healthy way to moderate blood sugar. Lemon juice, acidic fruits or
vinegar work well to slow the emptying of the stomach, due to increased gastric
acidity. Eating a carbohydrate like pasta or potatoes with a raw vegetable salad
is also a great way of moderating digestion of energy because of the added bulk
of cellulose fiber. There are times when you are going to want to treat yourself
to fries or mashed potatoes. A side dish of raw veggies will make the odd
indulgence guilt-free.
