WHITE BREAD: Eating too much white bread and other refined carbohydrates can sap your sex drive. Foods such as white bread release the sugar more quickly than their wholegrain counterparts -- and too much sugar is associated with energy slumps, which mean you won't have the energy for sex.

COLD & FLU REMEDIES: Over-the-counter cold and flu remedies are well-known libido dampeners. Those that contain diphenhydramine or pseudoephedrine not only affect your sex drive but can cause erectile dysfunction.

TONIC WATER: Quinine, the ingredient which gives tonic water its unique flavor, may affect libido.

In a separate study, they found it also significantly lowered sperm concentration and motility.
