Processed carbohydrate intake has predominantly unfavorable effect on lipid profile

BODY:


Highly processed carbohydrate intake has a predominantly unfavorable effect on lipid profile and may increase metabolic syndrome, diabetes, and coronary heart disease risk.

According to a study from the United States, "The effect of dietary carbohydrate on blood lipids has received considerable attention in light of the current trend in lowering carbohydrate intake for weight loss."

Y.S. Ma and colleagues at the University of Massachusetts conducted the present investigation "[t]o evaluate the association between carbohydrate intake and serum lipids. Blood samples and 24-hour dietary and physical activity recall interviews were obtained from each subject at quarterly intervals for five consecutive quarters between 1994 and 1998 from 574 healthy adults in Central Massachusetts. Relationships between serum lipids and dietary carbohydrate factors were assessed using linear mixed models and adjusting for other risk factors known to be related to blood lipids."

The researchers determined, "Both cross-sectional and longitudinal results were reported. Cross-sectional analysis results from this study suggest that higher total carbohydrate intake, percentage of calories from carbohydrate, glycemic index (GI) and/or glycemic load (GL) are related to lower high-density lipoprotein cholesterol (HDL-C) and higher serum triacylglycerol levels, while higher total carbohydrate intake and/or GL are related to lower total and low-density lipoprotein cholesterol (LDL-C) levels.

"In a 1-year longitudinal analysis, GL was positively associated with total and LDL-C levels, and there was an inverse association between percentage of calories from carbohydrate and HDL-C levels."

"Results suggest," concluded the authors, "that there is a complex and predominantly unfavorable effect of increased intake of highly processed carbohydrate on lipid profile, which may have implications for metabolic syndrome, diabetes, and coronary heart disease. Further studies in the form of randomized controlled trials are required to investigate these associations and determine the implications for lipid management."

Ma and colleagues published the results of their research in the Journal of the American College of Nutrition (Association between carbohydrate intake and serum lipids. J Am Coll Nutr, 2006;25(2):155-163).
