Objectives: Reducing sugar-sweetened beverage (SSB) consumption is associated with improved metabolic health in adults, but there is limited experimental research examining the consequences of adding SSBs to the diet. The aim of the current study was to determine the acute metabolic effects of adding SSBs, in the form of caffeine-free soda and 100% fruit juice, to the diet.
Methods: College-aged participants (18-30 years; n=36) were randomized to one of three beverage conditions: water (W), caffeine-free soda (S), or 100% fruit juice (FJ), and completed metabolic assessments (fasting glucose, triglycerides, and high-density lipoprotein; 2-hour glucose tolerance, waist circumference, and blood pressure). Participants consumed two servings (~710mL) of their assigned beverage each day for three weeks. All baseline assessments were repeated following the 3-week intervention.
Results: Preliminary results (n=27) indicate that 17 participants had at least one metabolic risk factor at baseline. There were no significant effects of time or beverage for glucose tolerance (incremental area-under-the-curve) (M±SD; Baseline: W:2945±1417, S:3327±1752, FJ:3165±1598 mg/dL x 2hr; 3-weeks: W:2614±1347, S:3703±1624, FJ:2635±1246mg/dL x 2hr; ps>0.05). There were also no significant differences between beverage conditions for changes in metabolic syndrome risk factors: Waist circumference (W:2.99±4.72%, S:-1.03±2.10%, FJ:2.04±3.30%; p=0.06), triglycerides (W:5.67±21.43%, S:45.08±61.94%, FJ:50.94±60.76%; p=0.18), HDL (W:6.73±15.84%, S:5.27±12.91%, FJ:-3.87±17.37%; p=0.32), blood pressure (Systolic: W:-3.00±4.66%, S:-2.30±5.97%, FJ:-2.64±7.86; p=0.97; Diastolic: W:1.72±6.09%, S:0.76±15.35%, FJ:-2.483±12.15%; p=0.74), and fasting glucose (W:5.61±4.51%, S:5.92±10.47%, FJ:6.28±4.92%; p=0.98).
Conclusions: Preliminary results suggest that the addition of SSBs, as caffeine-free Coca-Cola or 100% fruit juice, to the diet for three weeks does not modify metabolic healh. These results will help to elucidate the acute metabolic health outcomes associated with adding SSBs to the diet.
