Dried plum polyphenolic extract combined with vitamin K and potassium restores trabecular and cortical bone in osteopenic model of postmenopausal bone loss.
Dried plum has unique anabolic effects on bone, but the responsible bioactive components have remained unclear. This study investigated components of dried plum with potential osteoprotective activity utilizing aged, osteopenic Sprague Dawley rats fed diets supplemented with a crude polyphenol extract, potassium, vitamin K or their combination. Whole body and femoral bone mineral density were restored with the […]
In vitro and in vivo modeling of lipid bioaccessibility and digestion from almond muffins: The importance of the cell-wall barrier mechanism.
This study compares in vitro and in vivo models of lipid digestion from almond particles within a complex food matrix (muffins) investigating whether the cell-wall barrier regulates the bioaccessibility of nutrients within this matrix. Muffins containing small (AF) or large (AP) particles of almond were digested in triplicate using an in vitro dynamic gastric model […]
Nuts and their co-products: The impact of processing (roasting) on phenolics, bioavailability, and health benefits – A comprehensive review.
Nuts serve as important healthful snacks worldwide. They are highly desirable due to the presence of numerous essential macro- and micronutrients and health-promoting phenolic compounds (polyphenols). Nuts are usually consumed either as raw (natural) or as roasted. In addition, nuts and their co-products have been demonstrated to be rich sources of phenolic compounds that possess […]
Review of dried fruits: Phytochemicals, antioxidant efficacies, and health benefits.
Dried fruits, which serve as important healthful snacks worldwide, provide a concentrated form of fresh fruits. They are nutritionally equivalent to fresh fruits in smaller serving sizes, ranging from 30 to 43 g depending on the fruit, in current dietary recommendation in different countries. Daily consumption of dried fruits is recommended in order to gain full […]
Almond supplementation in the absence of dietary advice significantly reduces C-reactive protein in subjects with type 2 diabetes
Pistachio (Pistacia vera var Kerman) from Argentinean cultivars. A natural product with potential to improve human health
The chemical profile, mineral content as well as antioxidant activities of three cultivars of Pistacia vera cv Kerman were investigated. The total phenolic (TP) content flavonoids (FT) and anthocyanins (TA) were measured. Additionally, the profile of polyphenols was analyzed. A slight, not significant, increment was observed in TP content between cultivars with different age (5, […]
Phenolic composition and antioxidant capacities of ten Algerian date (Phoenix dactylifera L.) cultivars: A comparative study
Phenolic compounds and antioxidant capacities of ten Algerian date (Phoenix dactylifera L.) cultivars were investigated. The total phenolic, flavonoid, flavonol and condensed tannin contents of the different cultivars were measured using colorimetric methods. Free phenolic acid and flavonoid profiles of the date cultivars were analyzed by high performance liquid chromatography with diode array detection (HPLC-DAD), […]
Bioactive compounds from hazelnut skin (Corylus avellana L.): Effects on Lactobacillus plantarum P17630 and Lactobacillus crispatus P17631
Hazelnut skins are a good example of agro-food by-products, potentially source of natural antioxidants and functional food ingredients, rich in polyphenols and dietary fibre. The chemical characterization performed in our study confirmed that fibre is the main component of hazelnut skin. Moreover, four different polyphenols-rich extracts and two fibre fractions were obtained by the processing […]
Total polyphenolics and anti-oxidant properties of selected dried fruits and relationships to drying conditions
Abstract: The total polyphenolic (TPP) and antioxidant (AOX) levels of 41 Australian and imported dried fruits including sultanas (n = 22); Carina and Zante currants (n = 13); apricots (n = 3) and prunes (n = 3) were determined. Significant differences were observed among the sultanas; possibly due to local drying conditions; but not for […]
Phenolic compounds and antioxidant activity of Brazil nut (Bertholletia excelsa)
Brazil nuts were shelled and separated as kernel and brown skin; whole nuts were also used. Soluble phenolics from each portion as well as the whole nut were extracted using 70% acetone under reflux conditions. Insoluble-bound phenolics were subsequently extracted into diethyl etherÂethyl acetate mixture (1:1; v/v) after alkaline hydrolysis. Both soluble and insoluble-bound phenolic […]
