The effects of high walnut and cashew nut diets on the antioxidant status of subjects with metabolic syndrome

Abstract

Although the inclusion of walnuts and cashew nuts into a prudent diet resulted in an increased antioxidant capacity (ORAC) of the nut diets, compared to the control diet, it did not improve the serum antioxidant profiles of subjects with metabolic syndrome.

Chemical composition, molecular weight distribution, secondary structure and effect of NaCl on functional properties of walnut (Juglans regia L) protein isolates and concentrates

“…Protein solubility is known to increase with moderately increasing salt concentrations, due to the salting-in effect. The effective mechanisms of ionic strength on protein solubility include electrostatic interactions, solvent effect, salting-in and salting-out effect (Davis et al 2007). In comparison with other research reports, the solubility of walnut protein isolates (35.2%) in distilled water with 0 M sodium chloride was higher than that of Brassica carinata protein isolates (32%) (Pedroche et al 2004), sesame protein isolate (33%) (Khalid et al 2003) and cowpea protein isolate (32%) (Ragab et al 2004).…”

“…Carbohydrates contain hydrophilic parts, such as polar or charged side chains, which can enhance WAC (Jitngarmkusol et al 2008). Moreover, the differences in WAC between Isolate-A and Isolate-B can be attributed to the denatured proteins which can bind more water through exposure of hydrophilic groups (Davis et al 2007). WAC value of DWF (3.57 gg −1 ) was higher than 3.55 gg −1 of commercial soy protein isolate (SPI) reported by Ke-Xue Zhu et al (2010).…”

“…Moreover, walnut is not only an agricultural commodity, but its leaves, barks, stems, pericarps, fruits, flowers and ligneus membranes are all applied for different medicinal uses in China. These fruits are receiving increasing interest as a healthy foodstuff because their regular consumption has been reported to decrease the risk of coronary heart disease (Blomhoff et al 2006;Davis et al 2007;Albert et al 2002;Sabate et al 1993;Lavedrine et al 1999). In view of the increasing production of walnut globally, there is a need for an increased utilize of the walnut, especially the nutritious walnut kernel.…”

Preparation of Botanical Samples for Biomedical Research

“…Sprengel, a Mexican medicinal plant that is used in the folk medicine for the treatment of hypertension, diabetes, hepatitis, and related diseases was tested in bioassays related to metabolic syndrome and is confirmed with its hypoglycemic property [8]. Recently, the effects of dietary patterns, specific food consumptions, and fruit and vegetable consumptions on metabolic syndrome have been investigated in human clinical trials [9][10][11][12].…”

Mycotoxins that Affect the Human Cardiovascular System

“…In this way, cereals and oilseeds have contradictory properties; maize has oleic acid to protect against aflatoxin mutagenicity, and walnuts are considered part of a "healthy" diet that provides oils, proteins, minerals, flavonoids, tannins, phenolic acids, polyphenols, and antioxidants, which protect against fat nodules (atheroma plaques) in the arteries, are antiinflammatory and anti-mutagenic [41] and contain unsaturated fatty acids and vitamins [42], which protect against diabetes [43].…”
