Need a good reason to enjoy these sweet, succulent berries? New
research shows that raspberries may have 10 times more antioxidants
than tomatoes or broccoli.
In a recent study published in
BioFactors,
researchers from Plant Research International, Wageningen, The
Netherlands, explored the disease-fighting compounds, antioxidant
potential and health benefits of the raspberry.
In addition to
vitamin C and anthocyanins, raspberries contain some specific
antioxidants that are found almost nowhere else. The researchers found
that 50% of the mighty power of this tiny berry comes from
ellagitannins, found also in small doses in strawberries.
Because
raspberries spoil rapidly, storage and processing can affect the
antioxidant content of the fruit. The good news is that while flash
freezing can destroy much of the vitamin C, the antioxidant capacity of
the raspberry remains.
The variety and method of growing
affects the amount of antioxidants, too. Research shows that berries
grown organically have a higher antioxidant capacity than those grown
“conventionally” with health and environment-damaging pesticides.
Stock
up on these berry-delicious disease-fighters. Look for organic, flash
frozen raspberries (try Cascadian Farm) and enjoy these
antioxidant-rich treats.
