This study was designed to test the influence of dietary calcium and vitamin D levels on the promotional effect of high-fat diets on chemically induced mammary carcinogenesis. In a small preliminary experiment (Experiment A), 40 female Sprague-Dawley rats, 43 days old, were randomly divided into 5 groups (8 rats/group) and fed a semipurified diet containing 3% sunflower seed oil (SF) by weight,...

BACKGROUND Tissue Polypeptide Specific antigen has recently been proposed as diagnostic marker of apoptosis in NonAlcoholic SteatoHepatitis. The aim of this study was to validate in patients suffering from NonAlcoholic SteatoHepatitis the clinical utility of this marker after different programs of weight reduction. METHODS Overweight/obese patients with visceral adiposity and liver histology ...

RATIONALE Previous studies showed that obesity in asthmatic children is associated with more severe exercise-induced bronchoconstriction (EIB), compared with non-obese asthmatic children. This study investigates the effect of weight loss on EIB in overweight and obese asthmatic children. METHODS In this intervention study, children aged 8-18 years with EIB and moderate to severe overweight, f...

PURPOSE To evaluate the efficacy, safety and availability of a 12-week, community-based obesity control program called the Protein-Rich Oriental Diet (PRO Diet) and to compare it to a conventional diet. MATERIALS AND METHODS A total of 515 overweight people (55 men and 460 women; mean age 41.9 ± 9.8 years; body mass index (BMI) 28.1 ± 3.6 kg/m²) participated in the program at two public healt...

Obese and sedentary persons have increased risk for cancer; inflammation is a hypothesized mechanism. We examined the effects of a caloric restriction weight loss diet and exercise on inflammatory biomarkers in 439 women. Overweight and obese postmenopausal women were randomized to 1-year: caloric restriction diet (goal of 10% weight loss, N = 118), aerobic exercise (225 min/wk of moderate-to-v...

BACKGROUND Population-based studies have documented an association between obesity and an increased prevalence of asthma in women. METHODS We prospectively studied 58 obese women with a body mass index of > 30 kg/m(2), 24 of whom had asthma, who were enrolled in an intensive 6-month weight loss program to determine whether loss of body mass would be correlated with improvements in bronchial r...

Nutritional status may have significant importance for the immune system, and particularly, unsaturated fatty acids may serve as modulators of immune functions. Clinical and epidemiological studies have demonstrated that fatty acids are involved in the reduction of the inflammatory processes that occur in diseases characterized by an overactivation of the immune system. At the same time, an inc...

BACKGROUND Behavioural weight loss programs are effective first-line treatments for obesity and are recommended by the US Preventive Services Task Force. Gaining an understanding of intervention components that are found helpful by different demographic groups can improve tailoring of weight loss programs. This paper examined the perceived helpfulness of different weight loss program components...
