Effects of folic acid supplementation on hearing in older adults: a randomized; controlled trial.
Background: Age-related hearing loss is a common chronic condition of elderly persons. Low folate status has been associated with poor hearing. Objective: To determine whether folic acid supplementation slows age-related hearing loss. Design: Double-blind; randomized; placebo-controlled trial conducted from September 2000 to December 2004. Setting: The Netherlands. Participants: 728 older men and women recruited from […]
Characteristics of in-shell Brazil nuts and their relationship to aflatoxin contamination: criteria for sorting.
External characteristics of in-shell Brazil nuts were evaluated for dimensions (length and face width); weight; chromaticity; and shell thickness. The internal characteristics evaluated were moisture content (mc); aflatoxin contamination (analyzed by LC-MS/MS); and shell/nut ratio. According to their length; Brazil nuts were classified in three groups: I; II; and III; corresponding to large; medium; and […]
Nonisothermal Kinetics of Acrylamide elimination and its acceleration by Table Salt; A Model Study
Acrylamide was applied onto table salt and heated in a glass reaction vessel within the temperature range 50 to 210 degrees C with a heating rate of 2 degrees C/min in order to study the influence of temperature and table salt on acrylamide elimination. For comparison purposes; pure acrylamide was also heated at the same […]
Peanut (Arachis hypogaea) consumption improves Glutathione and HDL-cholesterol levels in experimental diabetes.
The aim of this investigation was to assess the influence of peanut (Arachis hypogaea) consumption on oxidant-antioxidant status and lipid profile in Streptozotocin (STZ) induced diabetic rats. 32 rats were divided into 4 groups as control; control+peanut; diabetic; diabetic+peanut. Control and diabetic groups were fed on standard rat chow whereas control+peanut and diabetic+peanut were fed […]
Chemical composition of edible Macadamia nuts (Macadamia integrifolia) and impact of soil quality
The distribution of eight selected elements (As; Ca; Cr; Cu; Fe; Mg; Mn and Zn) in edible Macadamia (Macadamia integrifolia) nuts from eight sampling sites in the south east coast region of South Africa is investigated. The levels of the elements in all the Macadamia nuts are found to be in the decreasing order of […]
Some rheological properties of aqueous peanut flour dispersions.
The rheological behaviors of aqueous peanut flour dispersions were characterized across a range of conditions; including controlled heating and cooling rates under both large- and small-strain deformations. Fat content of the dry flours influenced rheological changes; as dispersions of higher-fat flours were less viscous than lower-fat flours on an equal weight basis. A roast effect […]
Influence of plant lipids on immune responses in mice to the major Brazil nut allergen Ber e 1
BACKGROUND: Lipids; particularly bacterial lipopolysaccharide; can impact on immune responses to proteins; with low doses enhancing type 2 responses. OBJECTIVE: We have examined the influence of natural plant lipid extracts on antibody responses provoked in mice by recombinant Ber e 1; the major allergen in Brazil nuts. METHODS: BALB/c strain mice were immunized (by intraperitoneal […]
Allergy to cashew nuts and peanuts. Article in Dutch; Ned Tijdschr Geneeskd
Anaphylaxis due to the ingestion of peanuts is a serious; common condition; known to both the general public and physicians. Recently; an increasing number of patients with an anaphylactic reaction after eating small amounts of cashew nuts have been reported. In three children; a boy aged 7 and two girls aged 9 and 10 years; […]
IgE cross-reactivity between the major peanut allergen Ara h 2 and tree nut allergens
Allergy to peanut and tree nuts is characterised by a high frequency of life-threatening anaphylactic reactions and typically lifelong persistence. Although peanut is the most common cause of nut allergy; peanut allergic patients are frequently also sensitive to tree nuts. It is not known if this is due to cross-reactivity between peanut and tree nut […]
