Study: Eat "Good" Carbs for Health
Rat research supports benefits of eating low-glycemic index foods By Gabe Romain Betterhumans Staff 8/27/2004 4:33 PM Credit: National Cancer Institute Not so simple: A new animal study undermines the idea that all carbs are bad by showing how complex, low-glycemic index carbohydrates benefit health Note to Atkins dieters: Not all carbs are evil. A diet containing carbohydrates that are low in sugar or release sugar slowly can lead to weight loss, reduced body fat and lower risk factors for chronic illneses such as obesity, diabetes and cardiovascular disease, suggests a new study on rats. The findings, by researcher David Ludwig and colleagues of the Children's Hospital Boston in Massachusetts, is a step towards large-scale human trials of what are known as low-glycemic index (GI) diets. "What the study shows is that glycemic index is an independent factor that can have dramatic effects on the major chronic diseases plaguing developed nations-obesity, diabetes, and heart disease," says Ludwig. "This is the first study with hard endpoints that can definitively identify glycemic index as the active dietary factor." Good carb, bad carb The glycemic index is a measurement of the rate at which carbohydrate-containing foods raise blood sugar (glucose) levels. Foods with a high GI, such as white bread, refined breakfast cereals and concentrated sugars, tend to be digested rapidly by the body, increasing blood glucose and insulin levels. Low-GI foods, such as whole grains, fruits, vegetables and nuts, produce gradual rises in blood sugar and insulin levels, and have been shown to improve both glucose and lipid levels in people with diabetes. Low GI-foods can also regulate body weight by virtue of their ability to control appetite and increase satiety. Many studies have suggested, for example, that low-glycemic diets result in significantly more weight or fat loss than high-glycemic diets. Due to study design, however, the observed benefits could have come from other aspects of the subjects' diets, such as fiber or overall caloric intake. For this reason, says Ludwig, no major health agency or professional association references glycemic index in their dietary guidelines. Rodents at risk For the current study, Ludwig and colleagues fed rats diets with identical portions and identical nutrients, except for the type of starch-11 rats were given a high-GI starch diet and 10 were given a low-GI starch diet. At follow-up, the high-GI group had 71% more body fat and 8% less lean body mass than the low-GI group, despite very similar body weights. The high-GI group also had higher blood glucose and insulin levels and far more abnormalities in the cells that make insulin, all changes that occur in diabetes. Moreover, the high-GI group had blood triglyceride levels nearly three times that of the low-GI group. High blood triglyceride levels are a known risk factor for cardiovascular disease. In another experiment, 24 mice were randomly assigned to the low- or high-GI diet. At week nine, the high-GI group had 93% more body fat than mice on the low-GI diet. Atkins alternative The study shows that eating the right kind of carbohydrates can have tremendous health benefits. Some popular diets, particularly the Atkins diet, recommend restricting intake of all carbohydrates. There is evidence that a low-carbohydrate diet may help people shed weight more quickly than a low-fat diet, however, the long-term health effects of eating little or no carbohydrates are not known. "The Atkins diet tries to get rid of all carbohydrates, which we think is excessively restrictive," says Ludwig. "You don't have to go to this extreme if you pay attention to the glycemic index and choose low-GI carbs." The research is reported in The Lancet. -- Ken "Reading is the basics for all learning."

Really foolish .... the 1990's and 2000's Atkins books describe the Glycemic index and cite foods high in glycemic index as the carbohydrates to avoid. Actually Atkins has a Glycemic loading index which combines the rate at which blood sugar is increased along wtih the amount of drive to increase the blood sugar. So far, my reading hasn't uncovered a simple clear discussion of this loading index...... but I assume Atkins wasn't really stupid. Oh, now I see the viewpoint of some of these new "Researchers" or "so-called researchers". I found in metallurgy that you could find equally incompetent "so-called researchers", so the diet field doesn't have a special monopoly. Jim |

"The Atkins diet tries to get rid of all carbohydrates, which we think
is excessively restrictive," says Ludwig. "You don't have to go to this extreme if you pay attention to the glycemic index and choose low-GI carbs." I think people who report about the Atkins diet should read the book first. What a bunch of bull****. Yvonne |

Note to Atkins dieters: "blah, blah, blah", suggests a new study on rats. If I was a rat I would be really interested in this. Of course if i was a rat I wouldn't be able to read so i guess I wouldn't own a computer. Atkins alternative If you want to eat more carbs, become a rat. On a serious note - does this kind of testing actually benefit humans? Last I checked humans and rats are different. So as not to insult our rat population, I'm not saying humans are better, we're just different. It's apples and oranges - can I use this saying on a low carb board?? or should I say it's fish and chicken. Eva not a rat |

I found in metallurgy that you could find equally incompetent "so-called researchers", so the diet field doesn't have a special monopoly. Jim Glycemic load is much, much better than glycemic index. For instance, I starting looking into eating low carb because of eating brown rice, pasta cooked al dente, and grapefruit, each of which is low on the glycemic index. Nonetheless, they caused my blood sugar to skyrocket. Anyone know how they calculate glycemic load? I assume it would be something like: (glycemic index/100) * grams per serving of carbs, where "100" is the glycemic index for glucose (not white bread, which some scales use). Obviously, the nebulous "serving" comes into play here as well. Perhaps it should be done on 100g of product? -- Bob M remove ".x" to reply |
