Meta-Analysis of Randomized Controlled Trials of Red Meat Consumption in Comparison With Various Comparison Diets on Cardiovascular Risk Factors

BACKGROUND: Findings among randomized controlled trials evaluating the effect of red meat on cardiovascular disease risk factors are inconsistent. We provide an updated meta-analysis of randomized controlled trials on red meat and cardiovascular risk factors and determine whether the relationship depends on the composition of the comparison diet, hypothesizing that plant sources would be relatively […]

Influence of particle size and intestinal conditions on in vitro lipid and protein digestibility of walnuts and peanuts.

A static in vitro model was used to assess walnuts and peanuts macronutrient digestion of with two different particle size. Nuts were digested under different intestinal conditions of pH (6 or 7), bile concentration (1-10 mM) and pancreatic concentration (1000 to 4000 LU/g fat) the matrix degradation index (MDI), proteolysis and lipolysis were analyzed. Results showed that nuts particle […]

Biomarkers of food intake for nuts and vegetable oils: an extensive literature search.

Nuts and vegetable oils are important sources of fat and of a wide variety of micronutrients and phytochemicals. Following their intake, several of their constituents, as well as their derived metabolites, are found in blood circulation and in urine. As a consequence, these could be used to assess the compliance to a dietary intervention or […]

In Vitro Digested Nut Oils Attenuate the Lipopolysaccharide-Induced Inflammatory Response in Macrophages.

Nut consumption is known for its health benefits, in particular in inflammatory diseases. A possible mechanism for these effects could be their beneficial fatty acid composition. Nuts mainly contain mono- and polyunsaturated fatty acids, which have anti-inflammatory properties. However, studies investigating the effects of nut extracts on inflammatory processes on the molecular level are rare. […]

Edible nuts deliver polyphenols and their transformation products to the large intestine: An in vitro fermentation model combining targeted/untargeted metabolomics.

The fate of polyphenols from edible tree nuts was investigated using a simulated in vitro intestinal fermentation system. The digested food matrix was fermented for 48 h and the changes in the phenolic profiles were evaluated by both untargeted UHPLC-QTOF and targeted UHPLC-Orbitrap mass spectrometry. The untargeted metabolomics approach allowed us to monitor the comprehensive changes […]

The effect of nuts on markers of glycemic control: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Observational evidence suggests higher nut consumption is associated with better glycemic control; however, it is unclear if this association is causal. OBJECTIVES: We aimed to conduct a systematic review and meta-analysis of randomized controlled trials to examine the effect of tree nuts and peanuts on markers of glycemic control in adults. METHODS: A systematic […]

Nut Consumption in Relation to Cardiovascular Disease Incidence and Mortality among Patients with Diabetes Mellitus.

RATIONALE: The evidence regarding the potential health benefits of nut consumption among individuals with type 2 diabetes is limited. OBJECTIVE: To examine intake of total and specific types of nuts, including tree nuts and peanuts, in relation to subsequent risk of cardiovascular disease (CVD), including coronary heart disease (CHD) and stroke, and all-cause and cause-specific […]

Health benefits of nut consumption.

Nuts (tree nuts and peanuts) are nutrient dense foods with complex matrices rich in unsaturated fatty and other bioactive compounds: high-quality vegetable protein, fiber, minerals, tocopherols, phytosterols, and phenolic compounds. By virtue of their unique composition, nuts are likely to beneficially impact health outcomes. Epidemiologic studies have associated nut consumption with a reduced incidence of […]

Determination of serotonin in nuts and nut containing products by liquid chromatography tandem mass spectrometry.

An ultra performance liquid chromatography-mass spectrometry (UPLC-MS/MS) method was developed for the determination of serotonin in raw and roasted nuts (almond, Brazil nut, cashew, chestnut, coconut, hazelnut, Macadamia nut, pecan, peanut, pine nut, pistachio and walnut) as well as nut products (nut containing snack bars, chocolate and spreads) for the first time. Water extraction without prior defatting […]
