Health Benefits of Grapefruit: Weight Loss and Much More

Grapefruit is full of health benefits and it helps with weight loss! Also, grapefruit helps lower cholesterol, fights heart disease and so many other things. It is a powerful superfood.

Remember when a person gorged on grapefruit in the 1980s and seriously lost lots of weight?  It was highly restrictive but it turns out all those restrictions were not necessary, learn more below.

Health Benefits of Grapefruits

Grapefruit and Weight Loss

Eat half a grapefruit before each meal; it can help you lose up to a pound a week before sensible meals!

Or eat whatever you usually do and lose 3.6 pounds in 12 weeks. – Research at the Nutrition and Medical Research Centre at Scripps Clinic

Strangely, researchers are not sure how this works. They do know something in the grapefruit balances your insulin levels.  This could certainly cause weight loss but there may be other factors involved also.

Here are two studies verifying grapefruits help with weight loss.

  • A 12-week study had people who were overweight consume half a fresh grapefruit before a meal for 12 weeks, the results showed they lost almost 5 pounds after 4 weeks, and almost 11 ½ pounds after 12 weeks.
  • Another study with 91 obese patients was conducted to find out how grapefruit affected body weight, insulin resistance, and metabolic syndrome. They found that those who ate half of a fresh grapefruit before meals (meals had no restriction) lost 3.5 pounds in 12 weeks, improved insulin resistance and had a reduction in two-hour post-glucose insulin level.

“So far I’ve always kept my diet secret but now I might as well tell everyone what it is. Lots of grapefruit throughout the day and plenty of virile young men at night.”  – Angie Dickinson

We know grapefruit is helpful for weight loss. Grapefruits are also full of pectin, nutrients, and are low in calories and contain no saturated fats or cholesterol. On top of all those wonderful elements, they have many health benefits.

Grapefruit Health Benefits

Red Grapefruit Lowers Cholesterol & Fights Heart Disease

One red grapefruit a day can help keep heart disease away, according to a study by Israeli researchers in 2006. A major risk factor for heart disease is high blood cholesterol. In the study, the patients consuming one grapefruit per day significantly reduced cholesterol compared to a control group of patients that did not. The researchers say it may be because grapefruit has a high level of antioxidants.

Helps Reduce Lung Cancer Risk

White grapefruit contains a high amount of the flavonoid, naringin, which inhibits the activation of a cancer-causing enzyme. Pink grapefruit has some too, along with the antioxidant lycopene.

Inhibits Colon Cancer

Limonin, grapefruit pulp powder, and the flavonoid naringin, were examined in a study in relation to colon cancer cells. The scientists concluded that eating grapefruit may help to suppress the development of colon cancer.

Helps Repair Prostate Cancer

A study has shown that the citrus flavonoid naringenin stimulates DNA repair in prostate cancer cells.

Fresh Grapefruit Juice

 

Flushes Heavy Metal

It is full of pectin which binds to heavy metals, flushing them out in the digestive process. A study was performed with hospitalized children between the ages of 5 and 12 years who had high blood serum levels of lead. They were given three dosages of citrus pectin per day for 28 days. The scientists found that there was a dramatic decrease in blood serum levels of lead as a result.

Full of vitamin C, to help keep colds at bay

Another health benefit of grapefruit is that half a grapefruit has 38.4 mg of vitamin C which is 64 percent of the daily requirement.
1 cup of fresh raw pink grapefruit juice has 93.9 mg which is 156 percent of the daily requirement.
This compares with oranges, which have about 95 mg of vitamin C per 1 cup of oranges.

An Excellent Liver Detoxifier

Grapefruit contains glutathione, which helps the liver detoxify harmful chemicals.
According to research at Massachusetts General Hospital it may even help combat hepatitis C infection.

“Phytonutrients in grapefruit, called limonoids, inhibit tumor formation by promoting the formation of glutathione-S-transferase, a detoxifying enzyme. This enzyme sparks a reaction in the liver that helps to make toxic compounds more water soluble for excretion from the body.

Since those with chronic Hepatitis C are at a greater risk for developing cancer of the liver, inhibiting tumor formation is especially important. By helping the liver clear out cancer-causing toxins, limonoids’ promotion of detoxification enzymes is a simple way to ward off the development of cancer.” ~ Hepatitis Central

How to Choose a Sweet Grapefruit

They have a reputation for being sour and bitter, which can be a bit of a turn-off. If you learn how to choose a tasty grapefruit and some delicious ways to eat them, grapefruits can be sweet!

  • Slightly soft and heavy are the first things to feel for. The heaviness means the interior has been converted into sugar.
  • Winter is the best season to eat grapefruit.
  • Oro Blanco grapefruit is the sweetest, most tender, and juiciest of all the grapefruits. It has a golden yellow peel with a thick rind, and pith up to a 1/2 inch deep with a large hollow core.
  • Pink and red grapefruits are sweeter than the other white grapefruit varieties as a general rule. Choose a grapefruit with at least some red pigment for the sweetest fruit. Also, red and pink grapefruit get their colour from lycopene, a powerful antioxidant that helps fight cancer.
  • A good quality pink or red grapefruit has a smooth, firm, glossy thin peel. When the rind is thin, the fruit will be sweeter. When the peel is thick, the grapefruit is not ripe.
  • Look for an imperfect looking grapefruit when buying pink or red ones. Look for small irregular patches of gray-brown on the peel, as that is a sign of sweetness. Those patches developed from being in cold weather as they take up to 18 months to ripen. Often, they are harvested before they are ripe because markings are thought to spoil the beauty of the fruit. However, this need for perfection has given us sour grapefruits!
  • Grapefruits that are light and spongy, have a hard and thick peel, or are green in colour, are not sweet.

“Life is like a grapefruit. Well, it’s sort of orangy-yellow and dimpled on the outside, wet and squidgy in the middle. It’s got pips inside, too. Oh, and some people have a half a one for breakfast.” ~ Douglas Adams

Now you learned about the grapefruit health benefits, and know how to select the best, sweetest grapefruit, you have lots of good reasons to include it into your diet!
