Kamdar, a senior lecturer in pharmacy practice at Kingston University, explains that cranberries have a unique composition that makes them worthy of the title of "superfood" because of their amazing preventive and therapeutic abilities, which range from fighting inflammation to promoting heart health.
Research has demonstrated its effective role in several health fields, most notably:
Cranberries are known for their protective properties against urinary tract infections, especially in women and children who suffer from recurrent infections. The fruit contains proanthocyanidins, compounds that prevent bacteria (such as E. coli) from adhering to the bladder wall, the first step in an infection.
A study indicates that cranberry juice and tablets reduce infection rates and decrease the need for antibiotics, with the tablets being superior in effectiveness and cost.
Blueberries are rich in powerful antioxidants such as anthocyanins and quercetin, which protect cells from damage. Research shows that regular consumption can:
It raises the level of HDL (good) cholesterol.
It lowers the level of bad cholesterol, especially for diabetics.
It improves blood vessel elasticity and lowers blood pressure.
It reduces the level of homocysteine, an amino acid associated with inflammation.
Research is studying the role of cranberries in slowing the growth of cancer cells, due to their content of compounds such as "ursolic acid" which has an anti-inflammatory effect.
One clinical trial showed that drinking two cups of cranberry juice daily may reduce the risk of stomach cancer by preventing Helicobacter pylori bacteria from adhering to the stomach.
How should we consume it and what are the precautions?
Kamdar recommends eating fresh cranberries for maximum benefit, as they provide fiber and complete nutrients that supplements lack.
Most prone to kidney stones: because it contains "oxalates".
Heart patients taking warfarin: Juice may interact with the medication and increase the risk of bleeding. (Excessive consumption of juice or supplements may cause digestive problems, and sweetened juices lose much of their nutritional value).
