How Many Nutrients in Grapefruit Food

• Grapefruit and ugli fruit (a cross between the grapefruit and the tangerine) have moderate amounts of dietary fiber and, like all citrus fruits, are most prized for their vitamin C. Pink or red grapefruits have moderate amounts of vitamin A.

• One-half medium (four-inch diameter) pink grapefruit has 1.4 g dietary fiber, 1,187 IU vitamin A (51 percent of the RDA for a woman, 40 percent of the RDA for a man), and 44 mg vitamin C (59 percent of theRDA for a woman, 49 percent of the RDA for a man).

• One half medium (3.75-inch diameter) white grapefruit has 1.3 g dietary fiber, 39 IU vitamin A (2 percent of the RDA for a woman, 1 percent of the RDA for a man), and 39 mg vitamin C (52 percent of the RDA for a woman, 43 percent of the RDA for a man).

• Pink and red grapefruits also contain lycopene, a red carotenoid (plant pigment), a strong antioxidant that appears to lower the risk of cancer of the prostate. The richest source of lycopene is cooked tomatoes.

How To Buying Grapefruit Food

Look for:

Firm fruit that is heavy for its size, which means that it will be juicy. The skin should be thin, smooth, and fine-grained.

• Most grapefruit have yellow skin that, depending on the variety, may be tinged with red or green. In fact, a slight greenish tint may mean that the grapefruit is high in sugar.

• Ugli fruit, which looks like misshapen, splotched grapefruit, is yellow with green patches and bumpy skin.


Grapefruit or ugli fruit with puffy skin or those that feel light for their size; the flesh inside is probably dry and juiceless.

How To Storing Grapefruit Food

• Store grapefruit either at room temperature (for a few days) or in the refrigerator.

• Refrigerate grapefruit juice in a tightly closed glass bottle with very little air space at the top. As you use up the juice, transfer it to a smaller bottle, again with very little air space at the top.

• The aim is to prevent the juice from coming into contact with oxygen, which destroys vitamin C. (Most plastic juice bottles are oxygen permeable.) Properly stored and protected from oxygen, fresh grapefruit juice can hold its vitamin C for several weeks.

How To Preparing Grapefruit Food

• Grapefruit are most flavorful at room temperature, which liberates the aromatic molecules that give them their characteristic scent and taste.

• Before cutting into the grapefruit, rinse it under cool running water to flush debris off the peel.

• To section grapefruit, cut a slice from the top, then cut off the peel in strips starting at the top and going down or peel it in a spiral fashion. You can remove the bitter white membrane, but some of the vitamin C will go with it.

• Finally, slice the sections apart. Or you can simply cut the grapefruit in half and scoop out the sections with a curved, serrated grapefruit knife.

What Happens When You Cook Grapefruit Food

• Broiling a half grapefruit or poaching grapefruit sections reduces the fruit’s supply of vitamin C, which is heat-sensitive.

How Other Kinds of Processing Affect Grapefruit Food

Commercially prepared juices.

How well a commercially prepared juice retains its vitamin C depends on how it is prepared, stored, and packaged.

• Commercial flash-freezing preserves as much as 95 percent of the vitamin C in fresh grapefruit juices. Canned juice stored in the refrigerator may lose only 2 percent of its vitamin C in three months.

• Prepared, pasteurized “fresh” juices lose vitamin C because they are sold in plastic bottles or waxed-paper cartons that let oxygen in.

• Commercially prepared juices are pasteurized to stop the natural enzyme action that would otherwise turn sugars to alcohols.

• Pasteurization also protects juices from potentially harmful bacterial and mold contamination. Following several deaths attributed to unpasteurized apple juices containing E.

• coli O157:H7, the FDA ruled that all fruit and vegetable juices must carry a warning label telling you whether the juice has been pasteurized. Around the year 2000, all juices must be processed to remove or inactivate harmful bacteria.


Medical Uses and/or Benefits Of Grapefruit

• If you eat foods rich in vitamin C along with iron supplements or foods rich in iron, the vitamin C will enhance your body’s ability to absorb the iron.

• As a result people with scurvy do not heal quickly, a condition that can be remedied with vitamin C, which cures the scurvy and speeds healing. Whether taking extra vitamin C speeds healing in healthy people remains to be proved.

• Possible inhibition of virus that causes chronic hepatitis C infection. In January 2008, researchers at Massachusetts General Hospital Center for Engineering in Medicine (Boston) published a report in the medical journal Hepatology detailing the effect of naringenin, a compound in grapefruit, on the behavior of hepatitis viruses in liver cells.

• In laboratory studies, naringenin appeared to inhibit the ability of the virus to multiply and/or pass out
from the liver cells. To date, there are no studies detailing the effect of naringenin in human beings with hepatitis C.

Grapefruit Food/Drug Interactions

Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, naproxen and others. Taking aspirin or NSAIDs with acidic foods such as grapefruit may intensify the drug’s ability to irritate your stomach and cause gastric bleeding.

• Antihistamines, anticoagulants, benzodiazepines (tranquilizers or sleep medications), calcium channel blockers (blood pressure medication), cyclosporine (immunosuppressant drug used in organ transplants), theophylline (asthma drug).

• Drinking grapefruit juice with a wide variety of drugs ranging from antihistamines to blood pressure medication appears to reduce the amount of the drug your body metabolizes and eliminates.

• The “grapefruit effect” was first identified among people taking the antihypertensive drugs felodipine (Plendil) and nifedipine (Adalat, Procardia). It is not yet known for certain exactly what the active substance in the juice is.

• One possibility, however, is bergamottin, a naturally occurring chemical in grapefruit juice known to inactivate cytochrome P450 3A4, a digestive enzyme needed to convert many drugs to water-soluble substances you can flush out of your body.

• Without an effective supply of cytochrome P450 3A4, the amount of a drug circulating in your body may
rise to dangerous levels. Reported side effects include lower blood pressure, increased heart rate, headache, flushing, and lightheadedness. (chocolate)
