Increased lipid peroxidation plays a role in the pathology associated with fructose feeding. The present study reports the effects of metformin on the liver lipid peroxidation and antioxidant defence system of rats fed a high-fructose diet. The experimental animals were divided into two batches of 12 animals each. The control batch received a control diet containing 60% starch; the second batch...

Fish oil (FO) is a commonly used supplemental source of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), 2 n-3 (ω-3) polyunsaturated fatty acids (PUFAs) that have been shown to have a variety of health benefits considered to be protective against cardiometabolic diseases. Although the effects of EPA and DHA on lipid metabolism have been extensively studied, not all of the metabolic e...

BACKGROUND Chronic hypertension leads to cardiac hypertrophy, heart failure, and premature death. Little is known about the impact of dietary macronutrient composition on hypertension-induced cardiac hypertrophy and mortality. We investigated the effects of consuming either a high complex carbohydrate diet, a high simple sugar diet, or a high fat diet on cardiac hypertrophy and mortality in hyp...

INTRODUCTION The epidemic of metabolic syndrome is increasing worldwide and correlates with elevation in serum uric acid and marked increase in total fructose intake. Fructose raises uric acid and the latter inhibits nitric oxide bioavailability. We hypothesized that fructose-induced hyperuricemia may have a pathogenic role in metabolic syndrome and treatment of hyperuricemia or increased nitri...

Dietary fructose induces abdominal symptoms in patients with fructose malabsorption, but there are no published guidelines on its dietary management. The objective was to retrospectively evaluate a potentially successful diet therapy in patients with irritable bowel syndrome and fructose malabsorption. Tables detailing the content of fructose and fructans in foods were constructed. A dietary st...

Serum- and glucocorticoid-inducible kinase (SGK1) is transcriptionally upregulated by mineralocorticoids and activated by insulin. The kinase stimulates the renal epithelial Na(+) channel and may thus participate in blood pressure regulation. Hyperinsulinemia is triggered by dietary fructose, which sensitizes blood pressure for salt intake. The role of SGK1 in hypertensive effects of combined f...

F ructose is a sweet tasting sugar that is found naturally in fruits and some vegetables and has been part of the human diet—in modest amounts—for eons. The increasing consumption of sugar has dramatically increased our exposure to fructose (1). Sugar consumption has risen more than 40-fold since the Declaration of Independence was signed 250 years ago, andmore than 40% of the added sugars in o...

OBJECTIVE High-heat cooking of food induces the formation of advanced glycation end products (AGEs), which are thought to impair glucose metabolism in type 2 diabetic patients. High intake of fructose might additionally affect endogenous formation of AGEs. This parallel intervention study investigated whether the addition of fructose or cooking methods influencing the AGE content of food affect...

The present study was designed to examine the effects of various levels of fructose in a copper-deficient diet on some of the signs of Cu deficiency in the rat. Weanling male rats were randomly assigned to one of five diets which contained 0.6 micrograms Cu/g diet and 627 g carbohydrate/kg which was (g/kg): 627 fructose (diet 100); 470 fructose, 157 starch (diet 75); 313.5 fructose, 313.5 starc...

Insulin stimulates the tyrosine kinase activity of its receptor resulting in the tyrosine phosphorylation of pp185, which contains insulin receptor substrates IRS-1 and IRS-2. These early steps in insulin action are essential for the metabolic effects of insulin. Feeding animals a high-fructose diet results in insulin resistance. However, the exact molecular mechanism underlying this effect is ...
