Nutritional Quality of Wholegrain Cereal-Based Products Sold on the Italian Market: Data from the FLIP Study

The consumption of wholegrains (WG) is encouraged worldwide, but the lack of a common legal definition of such products leads to an unclear classification and identification on the grocery store shelf. In Italy, several products are generally sold as WG, but it cannot be determined if they are made entirely with all WG cereal(s) or if they are partially produced with WG ingredients (PWG). The aims of this study were to (a) survey the number of cereal-based food items formulated with WG, PWG, or refined (RG) present on the Italian market; and (b) analyse the nutritional quality, intended as nutrition facts, of WG products in comparison to PWG and RG. Nutritional information and declarations were retrieved from packs of 3040 products belonging to five different categories: breakfast cereals, biscuits, sweet snacks, bread, and bread substitutes. A descriptive analysis of the products and comparison of energy, macronutrients, fibre and salt among RG, PWG and WG products within each category was performed. In all categories, a major portion of the products did not contain WG ingredients. Results showed that the nutritional quality of RG, PWG, and WG products varied in relation to the product category and that WG inclusion cannot be always considered a marker of the overall nutritional quality of foods. Instead, it is necessary to evaluate the global product characteristics, and it is important to pay attention to differences between WG and PWG products that can be perceived by consumers as equivalent

Effect of “shape” on technological properties and nutritional quality of chickpea-corn-rice gluten free pasta

Macroscopic and microscopic food structural characteristics play an important role in product's technological properties and nutritional attributes. The effects of macroscopic (pasta shape, PS) and microscopic (flour particles, FP) structural attributes were independently investigated in gluten-free (GF) chickpea-corn-rice short pasta (50% chickpea) considering cooking quality, physicochemical attributes, thermal properties, in vitro digestibility of starch (IVSD) and protein (IVPD). Different PS (rigatoni, fusilli, fusilli piccolo, caserecce, gnocchetti sardi) and different chickpea FP (conventional, precooked, fine, coarse) were considered. With regards to PS effect, rigatoni-shaped pasta differed significantly from other PS having the longest cooking time, a harder and less adhesive texture, the highest gelatinization enthalpy, the lowest IVPD, and higher resistant starch content. The chickpea FP modulated the flour pasting properties and slightly impacted both pasta cooking quality and nutritional characteristics regarding IVSD and IVPD. This work suggested that pasta structural attributes, especially PS, can modify pasta cooking quality, physicochemical, and nutritional characteristics and should, therefore, be considered in rational product design to provide food products with desired properties

A systematic review and meta-analysis of the effects of flavanol-containing tea, cocoa and apple products on body composition and blood lipids: exploring the factors responsible for variability in their efficacy

Several randomized controlled trials (RCTs) and meta-analyses support the benefits of flavanols on cardiometabolic health, but the factors affecting variability in the responses to these compounds have not been properly assessed. The objectives of this meta-analysis were to systematically collect the RCTs-based-evidence of the effects of flavanol-containing tea, cocoa and apple products on selected biomarkers of cardiometabolic risk and to explore the influence of various factors on the variability in the responses to the consumption of these products. A total of 120 RCTs were selected. Despite a high heterogeneity, the intake of the flavanol-containing products was associated using a random model with changes (reported as standardized difference in means (SDM)) in body mass index (−0.15, p < 0.001), waist circumference (−0.29, p < 0.001), total-cholesterol (−0.21, p < 0.001), LDL-cholesterol (−0.23, p < 0.001), and triacylglycerides (−0.11, p = 0.027), and with an increase of HDL-cholesterol (0.15, p = 0.005). Through subgroup analyses, we showed the influence of baseline-BMI, sex, source/form of administration, medication and country of investigation on some of the outcome measures and suggest that flavanols may be more effective in specific subgroups such as those with a BMI ≥ 25.0 kg/m2, non-medicated individuals or by specifically using tea products. This meta-analysis provides the first robust evidence of the effects induced by the consumption of flavanol-containing tea, cocoa and apple products on weight and lipid biomarkers and shows the influence of various factors that can affect their bioefficacy in humans. Of note, some of these effects are quantitatively comparable to those produced by drugs, life-style changes or other natural products. Further, RCTs in well-characterized populations are required to fully comprehend the factors affecting inter-individual responses to flavanol and thereby improve flavanols efficacy in the prevention of cardiometabolic disorders

Catabolism of raw and cooked green pepper (Capsicum annuum) (poly)phenolic compounds after simulated gastrointestinal digestion and fecal fermentation.

A total of 21 (poly)phenolic compounds (free and bound) were quantified in raw, olive oil fried, sunflower oil fried and griddled green pepper before and after a simulated gastrointestinal digestion. Flavonoids, particularly quercetin rhamnoside, were the main compounds. The bioaccessibility of (poly)phenolic compounds after gastrointestinal digestion was higher in cooked (>82%) than in raw (48%) samples, showing a positive effect of heat treatment on the release of (poly)phenols from the vegetal matrix. Additionally, a faecal fermentation was carried out for 24h. A time-dependent microbial metabolic activity was observed, which resulted firstly (<5h) in the hydrolysis of flavonoid glycosides and then in the formation of 3 catabolites, namely 3,4-dihydroxybenzoic acid, dihydrocaffeic acid and 3-(3′-hydroxyphenyl)propionic acid, this being by far the most abundant. Catabolic pathways for colonic microbial degradation of flavonoids and hydroxycinnamic acids have been proposed. Griddled pepper showed the highest amount of (poly)phenols both after gastrointestinal digestion and colonic fermentation

Evaluation of the Nutritional Quality of Breakfast Cereals Sold on the Italian Market: The Food Labelling of Italian Products (FLIP) Study

Breakfast cereals are present on the market as different types and, in general, are one of the food categories in which voluntary information, such as nutrition or health claims (NHC) or gluten free (GF) declarations, have the largest distribution. The aims of the present study were to compare (i) the nutritional declaration among different types of breakfast cereals, as well as among products with and without NHC or GF declarations; and (ii) the salt and sugar contents with the &ldquo;Italian shared objectives for the improvement of the nutritional characteristics of food&rdquo;. To this aim, the nutrition declarations of 371 different breakfast cereal items, available in 13 retailers present on the Italian market, were analysed. Data showed an elevated inter-product variability, with cereal bars and muesli having the highest energy, total fat, and saturate contents per 100 g. Limited differences were found comparing products with and without NHC, as well as those with GF declaration. Most of the breakfast cereals were compliant to the shared objectives, although some items with NHC or GF declaration still have sugar or salt contents higher than these objectives. In conclusion, these data suggest that the different characteristics and the regulated information reported on the food label should not be considered as a marker of the overall nutritional quality. Thus, this study supports the importance of reading and understanding the information made on food label

The effect of chickpea flour and its addition levels on quality and in vitro starch digestibility of corn–rice-based gluten-free pasta

Development of gluten-free (GF) pasta with improved nutritional attributes is one of the main trends in the gluten-free pasta industry. Considerable interest lays in introducing legume-based ingredients into traditional corn/rice GF formulations. This work aims to fortify multi-cereal (cornrice) GF pasta with chickpea to investigate how different chickpea addition levels affect its quality and in vitro starch digestibility. Chickpea significantly increased pasta protein and dietary fibre contents to a level that supports the “source” or “high” fibre/protein content claims. Chickpea addition induced darkening, softening, adhesiveness decrease and solid loss reduction compared to the control. In addition, chickpea substitution significantly modified the in vitro starch digestion, which showed increasing resistant starch and decreasing slowly digestible starch contents suggesting potential mitigation of postprandial glucose response in vivo. Reformulating GF pasta with chickpea flour should, therefore, be considered as an effective tool to improve the corn–- rice-based GF products’ nutritional profile

A nutritional evaluation of various typical Italian breakfast products: a comparison of macronutrient composition and glycaemic index values

Breakfast foods with lower glycaemic responses are associated with better body weight control. Glycaemic index (GI) values of some commonly consumed breakfast foods in Italy were determined and compared, along with macronutrients. Cakes/pastries were low-medium GI (44–60), with high-sugar and saturated fat and low-fibre. Generally, mueslis and breads were medium GI (62–66 and 59–76, respectively) with higher fibre and lower saturated fat and sugar. The addition of spreads to bread lowered GI (47–66) but increased sugar and saturated fat
