Abstract

A number of meta-analyses of cohort studies have assessed the impact of glycemic load (GL) and glycemic index (GI) on cardiovascular outcomes. The picture that emerges is that for women, a significant association appears to exist between the consumption of high GL/GI diets and increased cardiovascular disease (CVD) risk. This association appears to be stronger in those with greater adiposity and possibly in those with diabetes, although these findings are not uniform. There is also an indication that raised CRP levels may be reduced, which has special implications for women whose CRP levels, as an emerging CVD risk factor, may be higher than men. For men, the situation is not as clear-cut. Although some studies show association, the meta-analyses have not demonstrated a significant direct association with CVD, despite current evidence that risk factors, including LDL-C, may be reduced on low-GI diets. Moreover, in a recent meta-analysis, increases in dietary GL have been associated with increased risk of diabetes, another CVD risk factor, in both men and women. Studies in men expressing relative risk of CVD in relation to GL and GI, with corresponding confidence intervals, are needed to provide the necessary power for future meta-analyses on this topic.

A randomized, blinded, crossover trial of 12 overweight or obese men (18-35 y) assigned to either a high- and low-GI meals controlled for calories, macronutrients, and palatability on two occasions. Cerebral blood flow was measured using arterial spin-labeling fMRI 4 hours after meals. Reported hunger was greater 4 h after the high- vs. the low-GI meal (P=0.04). At this time, the high-GI meal elicited greater brain activity (P = 0.0006 with adjustment for multiple comparisons) in the areas associated with reward and craving in the late postprandial period, a time with important implications to eating behavior at the next meal.

    •• Buyken AE, Flood V, Empson M. Carbohydrate nutrition and inflammatory disease mortality in older adults. Amer J Clin Nut. 2010;92:634–43. An Australian prospective cohort of 1,490 postmenopausal women and 1,245 men (49 y at baseline; 1992-1994) from who completed a validated food-frequency questionnaire. Over a 13-y period, 84 women and 86 men died of inflammatory diseases. Women in the highest GI tertile had a 2.9-fold increased risk of inflammatory death compared with women in the lowest GI tertile. No associations were observed, however, with cardiovascular mortality. CrossRefGoogle Scholar

Effects of weight loss and long-term weight maintenance with diets varying in protein and glycemic index on cardiovascular risk factors: the diet, obesity, and genes (DiOGenes) study: a randomized, controlled trial. Circulation. 2011;124:2829–38. A randomized trial of 932 overweight adults assessing the effect of macronutrient make-up and dietary GI on weight loss maintenance in a factorial design using five arms (four test, one control) over 26 weeks. Participants on low-GI arms had significant decreases in hs-CRP compared to high-GI arms, indicating low-GI carbohydrates may reduce low-grade inflammation. PubMedCrossRefGoogle Scholar
