GI Diet To Lower Blood
Definition and Benefits of a GI Diet
A GI diet is an eating plan based around the Glycemic Index (GI), a system for separating different types of dietary carbohydrates, according to how rapidly they raise blood-glucose (blood-sugar) levels inside the body. GI diets are typically beneficial for anyone with type 1 or type 2 diabetes, pre-diabetes, impaired glucose tolerance, hyperglycemia, PCOS, chronic food cravings, menopausal problems and hypothyroidism. A GI diet plan is very effective for weight loss, as it reduces cravings and stabilizes appetite.
How Carbohydrate Raises Blood Glucose
The type of carbs recommended by GI diets help maintain stable blood glucose. Point is, carbohydrate is our main source of energy. When we digest carbohydrate in our stomach, our digestive enzymes metabolize (convert) it into glucose which is then absorbed into the bloodstream. As our blood glucose levels rise, our pancreas releases insulin into the bloodstream. This insulin helps to "distribute" the blood glucose to energy-needy cells and tissues throughout the body. As the blood glucose is dispersed in this way, its level in the bloodstream gradually falls. Eventually, it falls below normal and our brain tells we're hungry and instructs us to eat.
When Our Blood Glucose Rises Too Rapidly
Unfortunately, certain types of rapidly digested carbs (eg. white flour carbs) cause our blood sugar levels to rise too quickly. When this happens, our pancreas releases an equally large amount of insulin in order to "balance" the expected surge of glucose. Typically, this large amount of insulin distributes the glucose too quickly, and our blood sugar levels fall too fast. This can cause two problems. (1) Within 1-2 hours we feel hungry again, and may end up overeating. (2) Having excessive amounts of insulin in our system may (if repeated often over time) cause our body to become less sensitive to its effect. More insulin is required to achieve the desired dispersal of glucose.
A GI Diet is Designed to Raise Blood Glucose More Slowly
Until 1981, all carbohydrate was believed
to raise blood sugar at a similar speed. Then
Type of Food in a GI Diet
A healthy GI diet is based on foods with a lower GI value. Typically, GI diets are low in fat (30 percent of calories) with an emphasis on monounsaturates and polyunsaturated essential fatty acids, moderate in protein (about 20 percent of calories), and contain about 50 percent of calories from carbs, with an emphasis on high fiber whole grains.
Types of Carbohydrate in a GI Diet
A healthy GI diet typically includes plenty of fruit (eg. apples, citrus fruits, berries), plenty of non-starchy and green leafy vegetables, regular servings of beans, peas and lentils (low GI and high in soluble and insoluble fiber), oily fish, lean meat, regular servings of starches such as dense chewy breads (whole grain, whole wheat, composed of stone-ground flour where possible), controlled portions of pasta, brown or basmati rice, eggs, lower-fat dairy foods, nuts and seeds.
GI Diets Advocate Eating Little and Often
A healthy GI diet typically recommends eating several meals/snacks throughout the day. This helps to maintain stable blood glucose levels and reduces food cravings that encourage overeating or sudden binges. Eating little and often also helps to maintain an efficient metabolism, so you burn calories at an optimal rate. All these benefits of a GI diet make it easier to lose weight.
Exercise Helps to Keep Blood Glucose Stable
A healthy GI diet plan always advises regular exercise. Physical exercise helps to reduce blood sugar in the bloodstream. This is why postprandial exercise is recommended for diabetics.
GI Diets - Best For Weight Loss, Best For Health
Carbohydrate-rich foods like vegetables, fruits, beans and wholegrains are highly nutritious. Such nutrient-dense foods keep us healthy and thus assist weight management - remember, a healthy body loses weight faster. And by selecting only lower-GI carbs, GI diets ensure that you obtain all your important nutrients without incurring the metabolic and digestive health problems associated with refined "Western" carbohydrates.
