Dietary consumption of fructose has increased by nearly 50% since 1960.
A high fructose diet (HFrD) results in greater visceral adiposity and systemic insulin resistance than a high glucose diet. The effects of fructose on liver fatty acid and ATP stores, systemic oxidative stress and cardiovascular status are not fully known.
The protocol will assess the following outcomes:
1. The ultimate fate of this increased hepatic fatty acid production following a high fructose vs. glucose diet
2. The effect of a high fructose vs. glucose diet on liver ATP stores
3. The effect of a high fructose vs. glucose diet on markers of oxidative stress
4. The effect of a high fructose vs. glucose diet on cardiovascular status
Factors critical to carbohydrate metabolism such as systemic insulin resistance, body composition, energy expenditure, physical activity will also be assessed.
32 centrally overweight healthy males with a low baseline fructose intake will be recruited. They will be randomised double blindly to receive 25% of their dietary energy requirements from either fructose or glucose for 14 days.
The sugars will first be taken in an energy balanced and then an overfeeding setting.
Allocation: Randomized, Control: Active Control, Endpoint Classification: Bio-equivalence Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Basic Science

The overall aim is to investigate if circulating fatty acids and lipids are influenced by alterations in carbohydrate amount and quality.

The purpose of this study is to determine the effect of different dietary zinc intakes on fatty acid metabolism and other zinc biomarkers
8 healthy male volunteers will be studied each on 3 occasions, ie - after 4 days on a weight maintenance diet containing 5% simple sugars + low physical activity - after...
The primary goal of this study is to provide a better understanding of: 1) the pathogenesis and pathophysiology of non-alcoholic fatty liver disease (NAFLD) in obese subjects, and 2) the e...
Alcoholic liver injury results in morbidity and mortality worldwide, but there are currently no effective and safe therapeutics. Previously we demonstrated that aldose reductase (AR) inhibitor amelior...
The effects of obesity on organophosphate pesticide-mediated toxicities, including both cholinergic and non-cholinergic targets, have not been fully elucidated. Therefore, the present study was design...
Dysregulation of the hepatic endocannabinoid (EC) system and high fat diet (HFD) are associated with non-alcoholic fatty liver disease. Liver cytosol contains high levels of two novel endocannabinoid ...

Lipid infiltration of the hepatic parenchymal cells resulting in a yellow-colored liver. The abnormal lipid accumulation is usually in the form of TRIGLYCERIDES, either as a single large droplet or multiple small droplets. Fatty liver is caused by an imbalance in the metabolism of FATTY ACIDS.
A non-essential amino acid that occurs in high levels in its free state in plasma. It is produced from pyruvate by transamination. It is involved in sugar and acid metabolism, increases IMMUNITY, and provides energy for muscle tissue, BRAIN, and the CENTRAL NERVOUS SYSTEM.
