  • Effects of dietary strawberry powder on blood lipids and inflammatory markers in obese human subjects. 22068016

    Obesity is a strong risk factor for the development of CVD, hypertension and type 2 diabetes. The overall goal of the present pilot study was to feed strawberries, in the form of freeze-dried powder, to obese subjects to determine whether dietary strawberries beneficially altered lipid profiles and reduced blood markers of inflammation compared with a control intervention. A total of twenty healthy subjects (thirteen females and seven males) aged between 20 and 50 years with a BMI between 30 and 40 kg/m2 completed the present 7-week double-blind, randomised, cross-over trial. Each subject received a prepared diet 7 d/week for 7 weeks consisting of approximately 35 % of energy from fat, 20 % protein, 45 % carbohydrate and 14 g fibre. Blood was collected on days 1 and 8 for baseline information. After the first week, subjects were randomly assigned to the strawberry powder (equivalent to four servings of frozen strawberries) or control (strawberry-flavoured) intervention for 3 weeks. For the remaining 3 weeks, subjects crossed over to the opposite intervention. Blood was collected again at the end of weeks 3, 4, 6 and 7. A comprehensive chemistry panel, lipid profile analyses and measurement of inflammatory mediators were performed for each blood draw. A 3-week dietary intervention with strawberry powder reduced plasma concentrations of cholesterol and small HDL-cholesterol particles, and increased LDL particle size in obese subjects (P < 0·05). Dietary strawberry powder reduced risk factors for CVD, stroke and diabetes in obese volunteers, suggesting a potential role for strawberries as a dietary means to decrease obesity-related disease.

  • Organizational effects of perinatal exposure to bisphenol-A and diethylstilbestrol on arcuate nucleus circuitry controlling food intake and energy expenditure in male and ... 23493373

    The endocrine disrupting compound bisphenol-A (BPA) has been reported to act as an obesogen in rodents exposed perinatally. In this study, we investigated the effects of early-life BPA exposure on adult metabolic phenotype and hypothalamic energy balance circuitry. Pregnant and lactating CD-1 dams were exposed, via specially prepared diets, to 2 environmentally relevant doses of BPA. Dams consumed an average of 0.19 and 3.49 μg/kg per day of BPA in the low and high BPA treatments prenatally and an average of 0.36 and 7.2 μg/kg per day of BPA postnatally. Offspring were weaned initially onto a normal (AIN93G) diet, then as adults exposed to either a normal or high-fat diet (HFD). Males exposed to the high dose of BPA showed impaired glucose tolerance on both diets. They also showed reduced proopiomelanocortin fiber innervation into the paraventricular nucleus of the hypothalamus, and when exposed to HFD, they demonstrated increased neuropeptide Y and Agouti-related peptide expression in the arcuate nucleus (ARC). Females exposed to the high BPA dose were heavier, ate more, and had increased adiposity and leptin concentrations with reduced proopiomelanocortin mRNA expression in the ARC when consuming a HFD. BPA-exposed females showed ARC estrogen receptor α expression patterns similar to those seen in males, suggesting a masculinizing effect of BPA. These results demonstrate that early-life exposure to the obesogen BPA leads to sexually dimorphic alterations in the structure of hypothalamic energy balance circuitry, leading to increased vulnerability for developing diet-induced obesity and metabolic impairments, such as glucose intolerance.
