Below are various health benefits of grapefruits;

1. Increases Metabolism (Good For Weight Loss)

Grapefruits and their juices are highly recommended for those who would like to lose weight. The fact of the matter is that grapefruits increase the body’s metabolism. In fact, grapefruit is so good in this role that you would continue burning sizable quantities of fat even when your body is inactive. Research has found that people who habitually ate one grapefruit each day burned well over 4 pounds of fat in 3 months. This is even when they did not make any further changes to their diets.

How is grapefruit adapted for its fat burning role? Grapefruits are high in fiber, enzymes, and water. They are also very low in sodium and calories. This allows them to lower insulin levels. So, instead of converting sugar into fats, they help the body to use the sugar as fuel — which leads to significant losses in weight. The fact that it is rich in fiber and water content leaves people feeling full. Thus, you are likely to eat less and burn more fats.

2. Grapefruit Suppresses Appetite

Grapefruit and its juice are effective suppressants of appetite. Grapefruit inhibits the feelings of hunger. This is why it is included in many weight loss programs. Grapefruit suppresses appetite by helping the body to release large amounts of the hormone cholecystokinin. Cholecystokinin, in turn, helps the body to suppress feelings of hunger by regulating the production of digestive juices.

3. Boosts The Immune System

Being rich in vitamin C, grapefruit is ideal for supporting and strengthening the immune system. Vitamin C works closely with other micronutrients like vitamins A and B6 to ensure your body maintains healthy levels of disease-fighting ability. This means that with adequate supplies of vitamin C and the other micronutrients, you would be able to ward off common ailments, and you would recover faster should you fall sick. In fact, studies indicate that the severity of a disease is heightened when the body lacks Vitamins C. According to research, as little as half a grapefruit per day is enough to supply you with up to 80% of your daily requirement of vitamin C.

4. Helps Combat Acidity

Grapefruit juice creates the right conditions in the intestines for optimal digestion and food absorption. The human body counters the citric acid in the fruit, and through this process, the digestion takes place under very efficient conditions. This means that you are less likely to suffer the effects of acidity even after a heavy meal. What’s more, you would reap more benefits from the food you consume as both the digestion of the food and its absorption are enhanced.

5. Grapefruit Helps Eliminate Constipation

A full glass of fresh grapefruit will go a long way in helping you fight constipation, especially when it is taken as part of breakfast. The juice does this by stimulating the entire digestive system. The stomach and intestinal walls, in particular, are stimulated to produce the gastric juices necessary to ease your bowel movement. Doctors often recommend fresh grapefruit juice to patients suffering from constipation.

6. It Is Good Against Influenza

It may be hard to avoid a flu outbreak. However, it is possible to control its intensity and duration by using grapefruit. Grapefruit does this in a couple of ways. First, it contains a flavonoid called naringin. This substance helps to minimize the acid levels in the system, and the body is thus able to hold its own against an influenza attack. Second, grapefruits have powerful antioxidants that have anti-cancer, antifungal, antiviral and antibacterial qualities. These qualities make grapefruit one of the best choices for defense against influenza and other common ailments.

7. As Treatment For Malaria

One of the most effective defenses against malaria is quinine. Quinine has been used in the tropical, malaria-prone regions of the world with massive success for many years now. Grapefruit contains a quinine-like substance that is effective for reducing malaria symptoms. However, do consult your doctor when taking grapefruit as a remedy for malaria symptoms.

8. As Treatment For Fever

The fact that grapefruit juice offers sufficient supplies of vitamin C makes it an ideal remedy for fever and other burning sensations that occur when one is unwell. By and large, doctors recommend that grapefruit juice can be taken when your body has reached unusually high temperatures as a result of one reason or another. What’s more, the large water content that the grapefruit holds will keep you hydrated. It is an easy way to replenish the water needs in your body in case of dehydration. It is important, however, that you seek the advice of your doctor before taking grapefruit if you are on other medication.

9. Grapefruit Speeds The Healing Of Wounds

According to Ann Marie Chiasson, MD, grapefruits are effective healers of wounds. The high content of vitamin C in the fruit makes the body to quickly generate new healthy tissues following an injury or surgery. Furthermore, the fruit helps the body to form new blood vessels. Being a surgeon herself, Chiasson often advises her patients to take about 500mgs of vitamin C before they go into surgery. This, she says, would enable them to recover so much quicker from their wounds.

Grapefruit inhibits cancer cells, helps the body to produce healthy cells of the colon and helps with digestion. All this is good news to people who are predisposed to suffer from cancer of the large intestine.

A study that appeared in a 2006 edition of the Journal of Nutritional Biochemistry showed that grapefruits are good for fighting off the effects of cancer of the prostate in men. The fruits have constituents that help repair damaged DNA, and they prevent the cancerous cells from growing further. The study further revealed that the Vitamin C present in grapefruits is good for combating cancers of the esophagus, breast, bladder, and stomach.

All these compounds are good for improved vision and healthy eyes. One grapefruit per day is enough to provide you with adequate supplies of these compounds.
