Low Glycemix Index Foods | Facts About Glycemix Index Foods One of the important factors when
trying to loose weight is to choose foods that keep your insulin
levels fairly constant. This is especially true in regards to
carbohydrates. When we eat foods that contain carbohydrates, the
carbohydrates are digested in the stomach and intestines and are
absorbed into the bloodstream, generally in the form of glucose.
When the carbohydrates we eat cause the
blood sugar to quickly rise to high levels,excess insulin can cause
to much sugar to be absorbed by the cells.This results in a condition
of low blood sugar. The subsequent stress on the body stimulates the
adrena glands to secrete hormones into the blood. Metabolism rises,
glucose is manufactured from stores in the liver and the entire body
may be activated in what is called “fight-or-flight response.”
The Glycemic Index (GI) is a
classification of ranking of carbohydrates, based on their potential
for raising blood glucose levels. Carbohydrates that are broken down
slowly and cause only a moderate increase in blood sugar, have a low
Glycemic Index Foods. Some carbohydrates fall in between.
Specifically, the Glycemic Index
measures how much a 50-gram portion of carbohydrates raises your
blood sugar levels compared with a control. The control is either
white bread or pure glucose. Glucose is absorbed into the bloodstream
faster than any other carbohydrate and is thus given the value of
100. Other carbohydrates are given a number relative to glucose.
Foods with low GI indices are released into the bloodstream at a
slower rate than high GI foods.
All carbohydrates cause some temporary
rise in your blood glucose level. This is called the glycemic
response. A number of factors influence this response: the amount of
food eaten, the digestion and absorption rate of food, including the
physical structure, ripeness, particle seize, the degree of
processing and preparation, the commercial brand, the nature of the
starch, acidity and the characteristics of the diabetic patient.
These factors naturally effect each food’s glycemic index position
or rank.
The slower your body processes the
food, the slower the insulin is released and the healthier the
overall effect is on your body. In addition, differences exist in the
glycemic indexes due to the choice of reference food, the timing of
blood sampling or the computational method used to calculate the
glycemic index.
When you desire to lose weight, you
choose the foods that raise your blood sugar level slowly. You’ll
discover that many of those foods are high in fiber and will keep you
feeling fuller for a longer period of time. And if you have been on a
diet, you will be thankful for this. The longer you feel satisfied,
the less temptation you will have to eat something in between your
meals that will spike your blood sugar.
As fructose is a slow moving sugar,
almost all fruits, except bananas and dried fruits, have a low GI.
Also, all vegetables that contain lots of fiber, except carrot and
corn. Whole grains, starches and pasta have a higher GI. On top of
the list are white bread, refined grains and some potatoes.
Following the latest research it
appears that women experience cravings about 10 times during the day.
The most common times for these cravings to appear are at 10 am and 4
pm. Interesting enough, these cravings correspond almost exactly to
your low blood sugar levels as well as your low levels of serotonin.
This is a chemical that drives women to start eating. And because the
drive is so strong, it’s quite difficult to overcome.
Research performed at the Massachusetts
Institute of Technology’s Clinical Research Center uncovered this
truth when it found a relationship between carbohydrates in the brain
and weight loss. Dr. J. Wurtman, lead researcher of the study,
demonstrated, that eating carbohydrates high on the GI raised the
levels of serotonin in the brain.
The results also showed that women
suffering from premenstrual syndrome eat to many carbohydrates and as
a result gain weight. Others overeat when they are depressed,
stressed or angry in an effort to balance these serotonin levels.
The objectives of diet management in
diabetic patients are to reduce hyperglycemia, prevent hyperglycemic
episodes, and reduce the risk of complications. For people with
diabetes, the GI is a useful tool in planning to achieve and maintain
glycemic control. High GI foods are absorbed quickly into the
bloodstream, causing an escalation in blood glucose levels and
increasing the possibility of hyperglycemia. The body compensates for
the rise in blood sugar levels with an accompanying increase in
insulin, which within a few hours can cause hypoglycemia. As a
result, awareness of the glycemic indices of food assists in
preventing large variances in blood glucose levels.
A low GI pre-event meal may be
beneficial for athletes who respond negatively to carbohydrate-rich
foods prior to exercise or who can’t consume carbohydrates during
competition. Athletes are advised to consume carbohydrates of
moderate to high GI during prolonged exercise to maximize
performance, approximately 1 gram per minute of exercise. Following
exercise, moderate to high GI foods enhance glycogen storage.
The fat content of food is one of the
components that affect the GI. Like fiber, fat acts like a brake on
the absorption process. Apart from this fact, fat just make food to
taste better. Fats also play an important role of signaling your body
to stop eating. This is vital to any weight-management program. The
fat that you eat causes the body to release a hormone called
cholecystokinin. This hormone is stored in the stomach until notified
by the presence of fat and is responsible for informing the brain
that you’re satisfied. It really is a marvellous thing and it means
you don’t have to deprive yourself.
Another factor that influence the
absorption rate of glucose is the protein content of the food.
Protein seems to have the greatest effect when it comes down to
satisfying those hunger pangs,especially for a long period of time
and makes you feel fuller. Protein also helps you to stay alert.
However, we have to be aware of the good and the bad protein. Always
make sure you choose the lean protein in either beef, fish, chicken
or plant-based protein.
Protein itself rates zero on the GI
scale, this means you don’t have to be sparingly by adding it to
your diet, only watch the calorie content. It slows down the rise in
insulin that happens when you eat any form of carbohydrate. This
means, if you add some protein to a food that ranks high on the GI
scale, you will counteract the spiking effect in insulin rise.
Another benefit of protein is, that it keeps you feeling full longer
after you eat it.It is therefore a good idea to add some protein to
your breakfast. And if you take a snack, make sure it contains some
form of protein.
If you like fish, you are doing
yourself a favor. Fish not only slows down the spiking in your
insulin level, it also contains a rich source of Omega-3 fatty acids.
Eat fish at least twice a week.
The Glycemic Index is an excellent
tool. It provide you with a weight-management system that puts you in
control of the foods you eat, how much you eat, the way you eat and
when you like to eat. When you have a good variety of foods from
which to choose, it makes it easier to stay with the system.
Try eating according to the Low Glycemic
Index Foods, you will be pleasantly surprised how easy it is to keep your
weight under control and you’ll also find that your energy level
will rise as a bonus!
