Anti-diabetic properties

Grapefruit products have been studied to have a positive impact on insulin resistance and blood glucose levels.

According to animal study results, mice that were fed a high fat diet and grapefruit juice for 100 days showed lower fasting blood glucose, fasting serum insulin and lipid levels and increased insulin sensitivity compared to control.

With similar effects grapefruit juice can be compared to metformin, most commonly prescribed anti-diabetic medications.

Although, important to note, these researches were conducted on animals, hence they have little relevance to humans and further studies are needed. The aim of these study was to provide evidence of potential health promoting properties of grapefruit juice

Possible cure against bad cholesterol

These medicinal properties of grapefruit have been studied in detail at the Hebrew University of Jerusalem.
It is scientifically proven that pectin allows you to remove cholesterol from the body.
Pectin is a main type of flavonoid in grapefruit.

In addition, this interesting Pubmed study demonstrates the effect of grapefruits on body weight.
91 Obese patients with metabolic syndrome were classified into 4 groups according to grapefruit consumption:

1 – Consumed fresh grapefruit
2 – Grapefruit juice
3 – Grapefruit capsule
4 – Placebo


Metabolic syndrome parameters and weight were measured at the start and 12 weeks after the diet.
First group that consumed fresh grapefruits had lost 36 pounds, the second group 33, the third 24 and the placebo group had only lost 1 pound.
Besides that, in the grapefruit groups there was a notable decrease in 2 hour post-glucose insulin level, supporting idea of grapefruit being beneficial product in cases of insulin resistance.

Unfortunately the mechanism behind those effects was not studied, but researchers concluded that grapefruit can confidently be used as an aid for weight loss diets.

Although we’ve got to accept the fact that, without adhering to a general healthy diet, all efforts of weight loss will be in vain.

Grapefruit is loaded is antioxidants

Antioxidants are well-known fighters against cancer, chronic diseases and infections.
Citruses are probably the first products that come to mind when speaking about rich Vitamin C content products. And it’s true.

52% of grapefruit is Vitamin C which is a strong water-soluble antioxidant, having the ability to protect cells against damage from reactive oxygen species. Furthermore, as stated by researches increased vitamin C dietary intake through fruits and vegetables can potentially be associated with lower rates of type 2 diabetes progression and its complications, although results are promising, more research is required on this topic.

Carotenes – an orange-red pigment giving grapefruit its darker color, is a crucial nutrient for preventing oxidative stress. There is evidence of carotene supplementations positively influencing cognitive function, vision and skin health.
Eye problems and dementia are quite common long-term complications for diabetics, beta carotene intake can potentially slow down these processes.

Grapefruit is rich with potassium

Grapefruit is a great source of potassium, 126 grams per 100 gram of fruit. This electrolyte has special importance in supporting the health of the heart and blood vessels.
Since diabetes makes people more susceptible to cardiovascular diseases, consuming potassium in grapefruit form does patients a great favor as it is commonly recommended for the prevention of atherosclerosis and heart failure.

Be cautious!

Grapefruit and grapefruit juice are known for their inhibitory effect on liver enzymes responsible for drug metabolism.
It’s even called pharmacologists’ nightmare, since it can interact with many medications and increase their concentration in the body. As we know, Type 2 diabetics are more prone to cardiovascular, neurological and other chronic diseases, hence they tend to be prescribed with a lot of therapeutic drugs.

In case you are taking lipid-lowering (statins), Blood pressure medications (Calcium channel blockers), Antiarrhythmics (Amiodarone) Antipsychotics (Benzodiazepines) or any other agents, grapefruit intake can significantly impact the concentration of medications in plasma which is dangerous for health. For that reason extra attention should be drawn to grapefruit portions, drug dosages and of course – consultation with a physician before making any changes to a diet is advised.

Portion control
Despite its amazing and numerous benefits for our health, it’s still a fruit with a quite rich content of carbohydrates, more specifically there is 7 grams of sugar per 100 gram fruit, that does us no good and is especially worrisome for diabetes.

Oral problems
Drinking grapefruit juice provokes severe soreness in the area of ​​the teeth and gums. To reduce the consequences after drinking the drink, it is better to rinse the oral cavity with water.

Allergic reactions
Grapefruits are quite a common trigger for allergic reaction, so it is not advised to use them for people who suffer from allergic reactions.
