Possible benefits and drawbacks of raspberries
Raspberries can increase the metabolism of fat cells, so their consumption may be useful in case of obesity. It also seems that they exert beneficial effects in terms of controlling blood sugar and anticancer properties. The latter would depend on the antioxidant and anti-inflammatory molecules present in the raspberries, but not only. It seems, in fact, that the ellagitannins can induce the death of cancer cells and prevent their proliferation.
Raspberries are sources of oxalate, substances which could cause the formation of kidney stones.
