Glycemic Load and Heart Disease

heartWe are living in a time where a major component of many of our deadly diseases are lifestyle choices.

The more we hear this information the more likely it will be that we can make the necessary changes that not only will have us feeling better but may actually save our lives.



The following excerpt talks about the relationship between high glycemic load and heart disease.

High carbohydrate intake has adverse effects on glucose metabolism, thereby creating potential worries to increase the risk of cardiovascular diseases. Dietary carbohydrates vary in their ability to increase postprandial blood glucose levels depending on different chemical structures, particle sizes, fiber contents, and food processing. The glycemic index (GI) measure is thus an indicator of how quickly a carbohydrate can be absorbed as glucose compared with a reference, which is generally white bread or pure glucose. Because the amount of carbohydrate in a food can vary, the glycemic load (GL) measure is used to represent both quantity and quality of carbohydrates and calculated by multiplying the GI of a food item with its carbohydrate content.

Our systematic review showed that high dietary GL, but not dietary GI, was associated with increased risk of stroke. The harmful effects were more pronounced for GL than for GI, which is expected as GL describes both quality and quantity of carbohydrates while GI represents only quality. Dietary GL is likely to be associated with more infusion of circulating glucose and higher postprandial insulin levels. Read More

Summary

High dietary glycemic load is associated with a higher risk of CHD and stroke, and there is a linear dose-response relationship between glycemic load and CHD risk. Dietary glycemic index is slightly associated with risk of CHD, but not with stroke and stroke-related death. Further studies are needed to verify the effects of gender and body weight on cardiovascular diseases. Read More
