Dietary onion intake as part of a typical high fat diet improves indices of cardiovascular health using the mixed sex pig model.

The aim of this study was to evaluate the potential health benefits of onions consumed at two levels of intake, using the pig model. The dietary fat content was set at a level typical of a "western" diet (25% w/w). Fifteen female and fifteen male pigs (Large White x Landrace) were allocated to one of three dietary treatments in a randomised block design.

Consumption of brown onions (Allium cepa var. cavalier and var. destiny) moderately modulates blood lipids, haematological and haemostatic variables in healthy pigs.

Although garlic and onions have long been associated with putative cardiovascular health benefits, the effects of different commercially available onions and level of intake have not been studied. Therefore, the aim of the present study was to evaluate the potential health benefits of raw onions using the pig as a biomedical model. Twenty-five female (Large White x Landrace) pigs were used in a (2 x 2)+1 factorial experiment.
