Low bone mineral density (BMD), osteopenia, and osteoporosis are frequent complications of celiac disease (CD). The etiology of pathologic bone alterations in CD is multifactorial; however, two main mechanisms are involved: intestinal malabsorption and chronic inflammation. A strict gluten-free diet (GFD) is thought to be the only effective treatment for CD; but treating bone complications related to CD remains complex. ⋯ Currently, a question of whether GFD alone is an effective treatment to correct the bone alterations in patients with CD is under debate. This review presents factors contributing to pathologic bone derangement, recent research on the epidemiology of low BMD, osteoporosis, and fractures, and the treatment of bone problems in patients with CD. The roles of calcium and transport mechanisms are additionally presented.

Randomized Controlled Trial
Moderate replacement of carbohydrates by dietary fats affects features of metabolic syndrome: a randomized crossover clinical trial.
Earlier studies on the management of metabolic syndrome (MetS) have mostly focused on very low carbohydrate diets, whereas long-term adherence to such diets is difficult for apparently healthy people. The aim of this study was to examine the effects of moderate replacement of carbohydrates by dietary fats on insulin resistance and features of MetS among women. ⋯ Moderate replacement of carbohydrates by dietary fats was not associated with statistically different changes in fasting plasma glucose, insulin, or atherogenic dyslipidemia among individuals with the metabolic syndrome; however, it resulted in decreased diastolic blood pressure and lower prevalence of the metabolic syndrome.

Review
Today's and yesterday's of pathophysiology: biochemistry of metabolic syndrome and animal models.
During the past 20 y, there has been much interest in sugars and especially fructose in relation to human health. Over the past decade, considerable scientific debate and controversy have arisen about the potential health effects of sucrose, high-fructose corn syrup (HFCS), and fructose itself. ⋯ This review will first systematically present a definition of MetS, its history, prevalence, and comparative diagnostic criteria. We will then consider fructose and its effects on human health, the diet-induced obesity model (various fat contents), the hypercholesterolemic model, the diabetes model, the hypertensive model, the MetS or insulin resistance model, and biomarkers related to MetS, in light of contemporary data using multiple databases (PubMed, MEDLINE, and OVID).

Faster eating and elevated circulating activity of alanine aminotransferase (ALT), a marker for liver injury, are risk factors for the development of obesity and type 2 diabetes mellitus, and their complications. The aim of this study was to examine the association between self-reported eating rate and circulating ALT activity in apparently healthy middle-aged Japanese women. ⋯ ALT activity is positively associated with faster eating, but is dependent on BMI in middle-aged, apparently healthy Japanese women.

Randomized Controlled Trial
Effect of soy product kinako and fish oil on serum lipids and glucose metabolism in women with metabolic syndrome.
At the doses typically used to treat hypertriacylglycerolemia, fish oil may increase low-density lipoprotein (LDL) cholesterol and blood glucose levels. The aim of the present study was to verify whether soy could attenuate the effects of fish oil on blood lipids and carbohydrate metabolism in patients with metabolic syndrome. ⋯ The present study showed that kinako moderates the adverse effects of high doses of fish oil on LDL cholesterol, total cholesterol, and glucose metabolism levels.
