Aflatoxins in hazelnuts and dried figs: Occurrence and exposure assessment.
A total of 300 samples of hazelnuts and dried fig were analysed for the incidence of any aflatoxins (AFs). High-performance liquid chromatography coupled with fluorescence detection (HPLC-FLD) method was used to quantify the amounts of AFs. The limit of quantification varied from 0.21 to 0.30μgkg(-1). No AFs were detected in shells of the hazelnuts, while […]
Fatty acids determination in Bronte pistachios by gas chromatographic method.
A gas chromatographic with flame ionization detector (GC-MS FID) method for the identification and quantification of fatty acids based on the extraction of lipids and derivatisation of free acids to form methyl esters was developed and validated. The proposed method was evaluated to a number of standard FAs, and Bronte pistachios samples were used for […]
Greater Adherence to the Alternative Healthy Eating Index Is Associated with Lower Incidence of Physical Function Impairment in the Nurses' Health Study.
BACKGROUND: Physical function is integral to healthy aging, in particular as a core component of mobility and independent living in older adults, and is a strong predictor of mortality. Limited research has examined the role of diet, which may be an important strategy to prevent or delay a decline in physical function with aging. OBJECTIVE: […]
More pistachio nuts for improving the blood lipid profile. Systematic review of epidemiological evidence.
Recent evidence suggests that regular intake of nuts may be associated with reduction of all-cause mortality, especially cardiovascular deaths. Among all types of nuts, pistachio displays the most favorable dietary composition. Therefore, we searched Medline and ISI Web of Science to identify interventional studies which evaluated changes of conventional blood lipids after replacing part of […]
Effects of walnut consumption on colon carcinogenesis and microbial community structure.
Walnuts are comprised of a complex array of biologically active constituents with individual cancer-protective properties. Here, we assessed the potential benefit of whole walnut consumption in a mouse tumor bioassay using azoxymethane (AOM). In study 1, a modest reduction (1.3-fold) in tumor numbers was observed in mice fed a standard diet (AIN-76A) containing 9.4% walnuts […]
Toxic and essential elements in five tree nuts from Hangzhou market, China.
In this study a total of thirty-five tree nut samples of walnut, pecan, pine seed, hickory nut and torreya were obtained from 5 farm product markets in Hangzhou, China and investigated for essential (Cr, Mn, Fe, Mo, Cu, Zn, Se, and Sr) and toxic (Al, As, Cd and Pb) elements by inductively coupled plasma-mass spectroscopy […]
Nut consumption and prostate cancer risk and mortality.
Background: Little is known of the association between nut consumption, and prostate cancer (PCa) incidence and survivorship. Methods: We conducted an incidence analysis and a case-only survival analysis in the Health Professionals Follow-up Study on the associations of nut consumption (updated every 4 years) with PCa diagnosis, and PCa-specific and overall mortality. Results: In 26 […]
Dietary Fiber and Bacterial SCFA Enhance Oral Tolerance and Protect against Food Allergy through Diverse Cellular Pathways.
The incidence of food allergies in western countries has increased dramatically in recent decades. Tolerance to food antigens relies on mucosal CD103+ dendritic cells (DCs), which promote differentiation of regulatory T (Treg) cells. We show that high-fiber feeding in mice improved oral tolerance and protected from food allergy. High-fiber feeding reshaped gut microbial ecology and […]
Global Perceptions of Food Allergy Thresholds in 16 Countries.
BACKGROUND: Food allergy is a growing global health issue that affects daily life and food purchasing habits. Quality data on the global consumer perspective of food allergy is limited, particularly about thresholds and food labeling risk. Many individuals with food allergy are counseled that small amounts of allergen can potentially cause life-threatening reactions, and to […]
Impact of peanut consumption in the LEAP Study: Feasibility, growth, and nutrition.
BACKGROUND: Early introduction of peanut is an effective strategy to prevent peanut allergy in high-risk infants; however, feasibility and effects on growth and nutritional intake are unknown. OBJECTIVE: We sought to evaluate the feasibility of introducing peanut in infancy and explore effects on growth and nutritional intake up to age 60 months. METHODS: In the […]
