The fruit might slow prostate cancer growth, according to a 2006 study by researchers at the University of California, Los Angeles in which men at risk for prostate cancer drank pomegranate juice daily. The fruit's extract showed it inhibited the growth of lung tumours in mice, according to a 2007 article in the journal Carcinogenesis. The fruit may even help to reduce dental plaque. Each pomegranate packs a powerful punch of the same free-radical fighting polyphenols that are found in green tea. And a pomegranate may even have more antioxidant power than a cup of green tea because it also contains isoflavones, which are commonly found in soy, and ellagic acid, which is commonly found in berries and nuts both believed to play a role in fighting cancer. These elements each contribute to pomegranate's superfruit title, but experts believe that it's the combination of these things that really helps the body fight disease.
Much like pomegranates, acai berries are loaded with antioxidants, but they are also a chock full of other good stuff, such as dietary fibre, vitamins, minerals, complex carbohydrates, amino acids and essential fats.
And acai berry is believed to help the body fight the effects of ageing better than most fruits, according to a 2008 study in the Journal of Agricultural and Food Chemistry.
Still, though much research has been done on the health benefits of this superfruit, Dr Steve Talcott of Texas A&M University, cautions that the benefits may only be seen when acai berries are added to a balanced diet. So while it may give you a small advantage in ageing, don't be quick to call it the "fountain of youth."
This superfruit is rich in beta-carotene and zeaxanthin, two powerful antioxidants. In addition, zeaxanthin absorbs blue light to protect the retina. Because of this, foods rich in zeaxanthin are believed to decrease the risk of age-related macular degeneration, according to a February study in the journal Optometry and Vision Science. Macular degeneration is the main cause of blindness in people over 65.
