2012 Graduate Student Research Grant Winner
Tanya Halliday, RD
Tanya Halliday, RD is a 2nd year doctoral student in the Department of Human Nutrition, Foods and Exercise at Virginia Tech. Halliday received a BS in Dietetics in 2010 from the University of Wyoming and in 2011, she completed a Dietetic Internship through the University of Houston. She has presented research at regional and national conferences and has been published in the ACSM journal, Medicine & Science in Sports & Exercise. She has served SCAN as a member of the Symposium Committee, the CV/W Leadership Team, and the Student Group Core Team. She also co-authored the vitamin D Fact Sheet for SD-USA.
Recently, it has been speculated that high added sugar (AS) intake may contribute to cardiovascular disease (CVD). Yet to date, no studies have examined the effect of habitual AS intake on arterial stiffness. Arterial stiffness is an important CVD risk measure because it represents the cumulative damaging consequences of traditional CV risk factors (i.e. – blood pressure, lipids, etc) and can indicate that CV risk is present even when traditional markers are normal. Therefore, the primary goal of this study is to determine if habitual AS intake is associated with arterial stiffness in adults. Measures will include: arterial stiffness; traditional CV outcomes; markers of inflammation and oxidation; and body weight/composition. Habitual AS intake will be evaluated by self-report and an objective blood biomarker of AS intake, δ13C. This project addresses an important gap in the literature related to AS intake, arterial stiffness, and CVD risk. This information is needed to determine if current AS intake recommendations are associated with a more favorable CV risk profile.
