The Glorious Greatness of Grapefruit

February is National Grapefruit Month, the perfect time to celebrate this glorious gift of nature.

The grapefruit is actually a hybrid fruit originating from 18th century Barbados, the result of an accidental cross between a sweet orange and a pomelo.

Grapefruits come in many colors: red, pink, white, and golden. The color is determined by the pigmentation of the fruit, which is a reflection of the fruit’s state of ripeness. (The variety you will see most often at the store has a yellow-white flesh and is called White Marsh Seedless).

Grapefruits are grown all over the world, and the US, China, and Mexico are the leading producers.

Avoid Mixing Grapefruit With Certain Medications!

When drugs are swallowed, they are metabolized by enzymes and/or they are absorbed by ‘drug transporters’, which are found in cells in the small intestine.

Grapefruit can negatively interact with either the enzymes or transporters, which means that either too much or too little of the drug is absorbed by the liver.

Many drugs are metabolized with the help of an enzyme called cytochrome P450 3A3 (CYP3A4) in the liver and small intestine.

Grapefruit can block the action of this enzyme, which means that, instead of the drug being metabolized, more of the drug enters into the blood and it stays in your body longer, leading to potential negative side effects.

For example, if you drink grapefruit juice while taking certain medications, too much of the drug might stay in your body, increasing the risk of liver damage and kidney failure.

On the other hand, if the grapefruit juice interacts with the drug transporters, it means that less of the drug enters the blood and the drug will not work as well.

Some types of drugs that can interact negatively with grapefruit include drugs used to lower cholesterol, lower high blood pressure, anti-anxiety drugs, corticosteroids that treat Crohn’s disease or ulcerative colitis and antihistamines, among others.

Obviously, not all drugs in these categories are affected by grapefruit. To make sure, it is best to check with your doctor before starting any new medication.
