Naringin is the flavanoid in grapefruit that gives it that lovely bitter taste. Naringin exists in all citrus fruits but grapefruit seems to have it as its major flavanoid. Btw, flavanoids are plant secondary metabolites - not directly involved in the growth of the plant but help in it.
Naringin may have a number of benefits :-
- Antioxidant activity
- Lowering of the blood lipids. (lipids are mostly fats but may also be waxes, sterols etc)
- Improvements in cognition
- Some tests (on rats) have shown it to reduce the effects of diabetes. In humans? IMHO, its beneficial.
Time for some grapefruit juice.
