The objective of the study was to explore the effect of glycemic-index dietary carbohydrates on blood flow.
Four meals were assessed:
(1) placebo (water)
(2) glucose (high glycemic)
(3) cornflakes (high glycemic)
(4) high-fiber cereal (low glycemic)
(a) blood glucose levels were significantly higher after glucose and cornflakes (high glycemic) compared with the low glycemic meal.
(b) high glycemic meals (glucose and cornflakes) reduced blood flow more than the low glycemic meal.
Lavi concluded that high-compared with low-glycemic carbohydrate consumption significantly suppresses blood flow, which suggests a mechanism whereby high-glycemic meals may enhance cardiovascular risk
