Objectives Prolonged exposure to stress is a risk factor for mental and physical health problems (i.e., depression, cardiovascular disease). Although higher consumption of fruit and vegetables (FV) has been associated with lower perceived stress (PS), the relationship between specific FV types and PS remains uncertain. The aim of this cross-section...

Scope Nitrate and nitrite are approved food additives in some animal-based food products. However, nitrate and nitrite in foods are strictly regulated due to health concerns over methaemoglobinaemia and the potential formation of carcinogenic nitrosamines. In contrast, plants (like leafy vegetables) naturally accumulate nitrate ions; a growing body...

Background Dietary nitrate is an important source of nitric oxide (NO), a molecule critical for cardiovascular health. Nitrate is sequentially reduced to NO through an enterosalivary nitrate-nitrite-NO pathway that involves the oral microbiome. This pathway is considered an important adjunct pathway to the classical l-arginine–NO synthase pathway....
Article
Scope: The cardioprotective effects of apples are primarily attributed to flavonoids, found predominantly in the skin. This study aimed to determine if acute and/or chronic (4 weeks) ingestion of flavonoid-rich apples improves endothelial function, blood pressure (BP) and arterial stiffness in individuals at risk for CVD. Methods and results: In...
Article
Vegetable derived nitrate is now recognised as an important bioactive phytochemical with cardioprotective properties. Nitrate, through the recently described enterosalivary nitrate-nitrite-nitric oxide (NO) pathway, increases NO, a molecule pivotal for cardiovascular health. Clinical trials have observed that dietary nitrate has similar effects to...
Article
Arterial wall thickening, stimulated by low-grade systemic inflammation, underlies many cardiovascular events. As diet is a significant moderator of systemic inflammation, the dietary inflammatory index (DII TM ) has recently been devised to assess the overall inflammatory potential of an individual’s diet. The primary objective of this study was t...

Apples are an important contributor to the intake of dietary components linked with cardiovascular disease (CVD) prevention. Apples have been shown to have beneficial effects on vascular function, blood pressure, lipids, inflammation and hyperglycaemia. The cardioprotective effects of apples, and other fruits, have been primarily ascribed to their...
Article
Background: Epidemiologic studies have suggested that a flavonoid-rich diet can reduce the risk of developing cardiovascular disease. Certain flavonoids, in particular quercetin, have been shown to ameliorate endothelial dysfunction and reduce blood pressure (BP), possibly by increasing the bioavailability of the potent vasodilator nitric oxide (N...

Cardiovascular disease (CVD) is the leading cause of death worldwide. There is a consistent inverse relationship between fruit intake with CVD events and mortality in cross-sectional and prospective observational studies, but the relationship of fruit intake with measurements of atherosclerosis in humans is less clear. Nutritional effects on abdomi...
Article
Higher fruit intake is associated with lower risk of all-cause and disease-specific mortality. However, data on individual fruits are limited, and the generalisability of these findings to the elderly remains uncertain. The objective of this study was to examine the association of apple intake with all-cause and disease-specific mortality over 15 y...
Article
Full-text available
Cardiovascular disease is a major cause of death worldwide despite the majority of its risk factors being preventable and treatable. The results of numerous epidemiological studies suggest that a diet rich in fruits and vegetables affords protection against CVD, and this may be attributed, in part, to the flavonoid quercetin. The aims of this revie...
