詳細な説明
The initiation and progression of atherosclerotic cardiovascular disease (CVD) is multifactorial in nature, and is currently thought of as a chronic inflammatory condition. To reduce the risk of CVD and its associated health care costs in California and elsewhere, nutrition and health recommendations strongly advocate the consumption of a diet rich in fruits and vegetables. Such recommendations are based largely on epidemiological data; the mechanisms underlying the putative positive effects of plant food-rich diets are poorly defined and an area of active debate.
In addition to essential vitamins and minerals, fruits and vegetables contain a number of bioactive compounds that may be involved in vascular function. In this regard, epidemiological studies have noted a significant inverse relationship between the intake of plant foods rich in polyphenols and the risk of both all-cause mortality and CVD. For example, the "French paradox" refers to diet patterns that, despite being high in saturated fat, are associated with a relatively low cardiovascular risk, which may be due, in part, to a robust intake of polyphenols found in red wine, grapes, and other plant foods. Red wine contains an array of phytochemicals that have been proposed to improve cardiovascular health, with a great focus on polyphenols. However, grape products such as dried cabernet grapes also contain substantial amounts of polyphenols that may be vasculoprotective.
