How Do They Grow?

  • Grapefruits grow in a cluster, similar to grapes, on large trees with glossy dark green leaves. The trees are planted in rows called groves.
  • Grapefruits grow best in tropical or subtropical regions, such as south Texas, where it is warm year around.
  • In South Texas, grapefruit is harvested between October and May. For best quality, grapefruit ripens on the tree and is hand-picked. Area shippers wash, inspect and grade them before shipping to stores throughout the United States and Canada.

Nutritional Values

In 1970, the grapefruit diet plan was promoted widely to achieve a loss of 10 lbs weight in 10 days. The fruit is customarily a breakfast fruit. Some consumers sweeten it with sugar or honey. Some add cinnamon, nutmeg or cloves.

It is also served as an appetizer before dinner. The sections are commonly used in fruit salads, puddings, and tarts. It is also processed as a marmalade in Australia. The juice is marketed as a beverage.

It also can be made into an excellent vinegar or carefully fermented as wine. Raw grapefruit juice (per 100gm) contain calories 37-42, moisture 89.2-90.4g, niacin 0.2mg, ascorbic acid 36-40mg, vitamin A 10-440 IU, potassium 162mg, phosphorus 15mg, calcium 9mg, carbohydrate 8.8-10.2g, protein 0.4-0.5g, fat 0.1g, iron 0.2mg, sodium 1.0mg, riboflavin 0.02mg, thiamine 0.04mg

Pharmacology

It has been demonstrated to have a preventive influence on many chronic diseases, such as cancer and cardiovascular diseases. An essence prepared from the flowers is taken to overcome insomnia, also as a stomachic and cardiac tonic.

The pulp is considered an effective aid in the treatment of urinary disorders. Leaf extractions have shown antibiotic activity. However, since the early 1990s, the potential health benefits of grapefruit have been overshadowed by the possible risk of interactions between drugs and grapefruit juice.

Concomitant administration of grapefruit juice can increase the plasma concentration of numerous drugs in humans and also decrease the concentration of a few other drugs.

The use of grapefruit juice with a few drugs may lower plasma drug concentrations by inhibiting drug absorption catalyzed by the organic anion transporting polypeptide.

It also inhibits P-glycoprotein, a transporter that carries drugs from the enterocyte back to the gut lumen, resulting in a further increase in the fraction of absorbed drugs.

Inhibition of P-glycoprotein is a possible mechanism that increases oral drug bioavailability by reducing intestinal efflux transport.

A single normal amount (e.g. 200-300 mL) or by whole fresh fruit segments can inhibit drug-metabolizing enzymes, can increase the oral bioavailability of a drug and enhance its adverse effects [5,6]. Enhanced oral drug bioavailability can occur 24 hours after juice consumption as the duration of effect of grapefruit juice can last 24 hours.

These interactions appear to be influenced by individual patient susceptibility, type and amount of grapefruit juice and administration-related factors. Therefore patients should take their medications at least 4 hours distant from fruit juice intake.

Drug Interactions

It has a high antioxidant activity. It contains lycopene, limonoids which appear to have anti-tumor activity. It can reduce blood levels of LDL and triglycerides as well.

Substances in grapefruit can change the metabolism of the drug and increase the amount of medication that enters the bloodstream to dangerous levels.

The amount of drug-metabolizing enzymes may vary from person to person. So grapefruit juice may affect people differently. Table-1 shows the possible drug interaction of Grapefruit juice.

Boosts Metabolism

It is a popular diet staple among those looking to lose weight. A high metabolism can continue to burn fat in the body even when it is resting.

Drinking up to a liter of grapefruit juice daily will help reap the greatest benefits in effectively blocking the formation of kidney cysts.

Protects Against Cancer

The antioxidant vitamin C has been linked to a decrease in the risk of certain cancers. A study found grapefruits help repair damaged DNA in human prostate cancer cells. Stimulates DNA repair in these cancer cells and protects the body from developing cancer.

Diets high in vitamin C, which is an antioxidant found in many fruits and vegetables such as grapefruit, had been linked to a reduced risk of cancers of the stomach, colon, bladder, breast, and esophagus. Cautions these results are specific to vitamin C rich foods, rather than supplements.

Strengthens Immune System

It is well known any fruit rich in vitamin C will strengthen and support our immune system. Vitamin C works with other micronutrients that provide good and regular nourishment for the body.

Micronutrient deficiencies of vitamins A, B6, C, and E have been found to alter immune responses in animals and are thought to have a similar effect on the human immune response.
Maintaining good levels of vitamin C in the body can reduce the severity of cold symptoms, acting as a natural antihistamine.

This makes it helpful in controlling allergies since it reduces histamine levels. It is abundant in vitamin C which helps supports the immune system. Half of a grapefruit provides about 78 percent of your recommended daily intake of Vitamin C.

Fights Gum Disease

Simply eating two grapefruits a day can prevent and even reverse damage caused by gum disease. A  study found the daily consumption of grapefruit can reduce gum bleeding for those who suffer from gum disease.

The participants in the study also showed an increase in their vitamin C levels, which aids in the repair of gums. Vitamin C is essential for healthy gums, which helps keep our teeth firmly in place.
