Increasing arginine in the diet can improve endothelial function and lower blood pressure, increase HDL, and have other beneficial effects. Arginine is unlikely to have a dramatic 'instant-on' effect like viagra, but might improve nitric oxide levels and erectile function over time in some men with mild or moderate dysfunction.Anonymous[email protected]tag:blogger.com,1999:blog-37623912.post-70967964168162362052008-07-07T11:40:00.000-04:002008-07-07T11:40:00.000-04:00I don't know about watermelons, but for many just the thought of melons always seem to do the trick!Anonymous[email protected]tag:blogger.com,1999:blog-37623912.post-82920362660876751702008-07-07T03:13:00.000-04:002008-07-07T03:13:00.000-04:00The researchers say that the effect is entirely organ non-specific, as you point out. This "news" item can only be described as a piece of PR puff, probably originated by a summer intern in the Texas press office. Needless to say, it worked. Everyone's talking about the hard science of watermelons...David Bradleyhttp://www.sciencebase.com[email protected]
