In recent years, there has been a great deal of interest and controversy surrounding the impact of low-fat high-carbohydrate vs. high-fat low-carbohydrate foods and their impact on overall health (body weight; plasma lipids; insulin sensitivity; cardiovascular health). Over the last ten years, my research has focused primarily on how the amount and quality of dietary fats and carbohydrates affect body composition, as well as the metabolism of lipoproteins in the fasting and fed (postprandial) state. Another focus of these studies has been to better understand the physiological determinants of the postprandial lipid response in individuals with a perturbed metabolism of triglyceride-rich lipoproteins (visceral obesity; NIDDM, etc.). This research is predominantly clinical in nature and is ultimately aimed at elucidating the mechanisms whereby diet affects lipoprotein metabolism and kinetics in both healthy individuals and those at increased risk for coronary heart disease.

My most recent project in this area is aimed at determining the effects of resistant vs. rapidly digested starches on blood glucose and insulin responses and on components of the atherogenic lipoprotein phenotype (ALP), a dyslipidemia associated with obesity, insulin resistance and diabetes that is characterized by high triglycerides, low HDL cholesterol, and increased levels of small dense LDL. We hypothesize that a high-carbohydrate diet consisting primarily of starches that are resistant to enzymatic degradation by alpha-amylases will improve glycemic control and components of ALP compared to rapidly digested starches. We further hypothesize that these benefits will be accentuated when resistant starch is included in a lower-carbohydrate high-fat diet. This 8 week dietary intervention trial is ongoing and the last participants are expected to complete the study in Fall of 2011.

We recently launched a dietary intervention trial aimed at assessing whether modification of the DASH (“Dietary Approaches to Stop Hypertension”) diet by substituting carbohydrate with fat will result in improvements in multiple biomarkers of CVD risk. Specifically, we will test the hypotheses that modification of the DASH diet by reducing carbohydrate, primarily in the form of simple sugars and glycemic starches, and allowing for a more liberal intake of fat will: (1) improve lipoprotein markers of CVD risk (reduced total/HDL-C, apolipoprotein B, small LDL particles; and increased HDL-C, apoAI, and large HDL particles); and (2) result in comparable reductions of systolic and diastolic blood pressure to those achieved with the standard DASH diet. We will also assess the effects of the modified DASH diet on markers of insulin resistance and inflammation.

Ultimately these projects are aimed at providing a better understanding of the metabolic determinants of atherogenic dyslipidemia and its modulation by diet. These clinical research projects are conducted in collaboration with Dr. Ronald M. Krauss, at Children’s Hospital Oakland Research Institute.
