Diabetes is a global pandemic which warrants urgent attention due to its rising prevalence and economic burden. Thus, many alternative therapies are being researched for antidiabetic properties, given the inefficacy of current medicinal treatments. From this perspective, Aronia melanocarpa or black chokeberry has been investigated for its therapeutic properties in many studies, especially for its ability to combat hyperglycemia-induced oxidative stress and the macrovascular complications of diabetes including cardiovascular disease. Though A. melanocarpa is native to the eastern areas of North America, it has been planted extensively in Europe and Asia as well. Several in vivo studies have displayed the antioxidant properties of A. melanocarpa berry juice and plant extract in rat models where oxidative stress markers were observed to have significant reductions. Some of the potent bioactive compounds present in the fruits and other parts of the plant were identified as (−)-epicatechin, chlorogenic acid, neochlorogenic acid, and cyanidin-3-galactoside. Overall, A. melanocarpa could be considered a good source of antioxidants which is effective in combating hyperglycemia-induced oxidative stress.

Mobile dietary record apps have been increasingly validated by studies with various study designs. This review aims to evaluate the overall accuracy of dietary record apps in measuring the intake of energy, macro- and micronutrients, and food groups in real-life settings and the designs of validation studies. We systematically searched mobile dietary record validation studies published during the period from 2013 to 2019. We identified 14 studies for the systematic review, of which 11 studies were suitable for meta-analyses on energy intake and 8 studies on macronutrient intake. Mean differences and SDs of nutrient estimations between the app and the reference method from studies were pooled using a random-effects model. All apps underestimated energy intake when compared with their reference methods, with a pooled effect of −202 kcal/d (95% CI: −319, −85 kcal/d); the heterogeneity of studies was 72%. After stratification, studies that used the same food-composition table for both the app and the reference method had a lower level of heterogeneity (0%) and a pooled effect of −57 kcal/d (95% CI: −116, 2 kcal/d). The heterogeneity of studies in the differences in carbohydrate, fat, and protein intake was 54%, 73%, and 80%, with the pooled effect of −18.8 g/d, −12.7 g/d, and −12.2 g/d, respectively, after excluding outliers. The intakes of micronutrients and food groups were statistically nonsignificantly underestimated by the apps in most cases. In conclusion, dietary record apps underestimated food consumption compared with traditional dietary assessment methods. Moreover, varying study designs have been found across studies. Recommended practices for conducting validation studies were formulated including considering biomarkers as the reference, testing in a larger and more representative study population for a longer period, avoiding the learning effect of each method, and comparing food group or food item consumption in addition to comparing energy and nutrient intakes.

Purpose – In recent years, consumers have developed an interest in the type and the quality of food they eat. As consumers’ opinion is very important in identifying development strategy for food industry it seems justified finding out if geographical region had an influence on consumers’ opinion. Furthermore, this is the topic that is still under researched. The purpose of this paper is to investigate consumers’ perception of functional food (FF) relative to geographical region. Design/methodology/approach – Questionnaire based survey was conducted on a representative national sample with participants aged 18 and older (n=687). Participants were divided according to their place of residence taking into account difference in dietary habits, which created two geographical sets: Coastal (Adriatic) Croatia and Continental Croatia. Data were analyzed using univariate statistics and multivariate analysis as exploratory factor analysis, cluster analysis and principal component analysis. Findings – The results indicate that Croatian consumers are familiar with the term “FF” and that there are significant differences between two geographical sets of respondents (Coastal Croatia and Continental Croatia) in their willingness to pay for FF. Furthermore, research showed that there is a general lack of confidence in the information provided on the product labels especially in the continental region. The results have shown that “taste” and “price quality ratio” are the most important features in choosing the FF and are equally important to the consumers’ in both geographical region. Practical implications – Research results indicate a need for development of consumers’ confidence and need to focus mainly on educating consumers in label comprehension. This is particularly true for the Continental Croatia. Targeted advertising should take into account consumers’ preferences, confidence and label comprehension according to their geographical regions. Originality/value – The case study represents consumers’ opinion coming from different geographical regions (Coastal Croatia and Continental Croatia) regarding FF. In this research the most important attributes in choosing the FF were extracted.

This study has shown that Croatian women with polycystic ovary syndrome compared to the controls have significantly poorer dietary habits characterised by high Glycaemic Index diets, they are less physically active during free time. and have positive significant correlation between the age and carbohydrate intake whereas the controls have positive significant correlation between the age and fat intake.
