Reports have shown it occurs in more than 25% of Australian population over the age of 65.

Osteoarthritis is a disease of entire joint affecting joint cartilage, its ligaments and underlying bone. It is a degenerative disease showing symptoms such as joint pain, stiffness, weakness in joint muscles and numbness in arms and feet. There are number of factors which causes this disease such as aging, being overweight, injury of a joint, genetic problem and stress on joints due to occupation or sports activity

  • Avoid stress on joint – If you have any joint injury due to sports or occupational accidents, protect it before it turns into arthritis.
  • Weight control – It is observed that this type of arthritis increases with weight and hence controlling weight mainly in obese people is the main criteria.
  • Medication – Some pain killers recommended by your doctor can help to reduce intense pain.
  • Surgery – This treatment is suggested in extreme and advanced condition when other techniques does not work on patients such as knee replacement.
  • Diet – Fruits and vegetables such as papaya, pineapple, oranges, grapefruits, cauliflower, broccoli which are rich in vitamin C, vitamin D and omega 3 fatty acids have shown to reduce the progression or development of osteoarthritis.

Health Benefits of Grapefruits

grapefruitGrapefruit was bred in the 18th century and it was formed when an orange was crossed with a pomelo. It was named grapefruit because it grew in clusters like grapes.

This article focuses on the effectiveness of grapefruit in osteoarthritis.

3 Awesome Benefits of Grapefruit In Osteoarthritis

Here are some interesting and science backed health benefits of grapefruit in osteoarthritis.

1.Vitamin C in grapefruit protects against osteoarthritis

Grapefruit is a rich source of vitamin C and a lot research has been conducted to assess the effects of vitamin C on osteoarthritis.

The Framingham epidemiological study reported that if you take sufficient amount of vitamin C, then the risk of developing osteoarthritis reduces by 3 times. This means that there is an inverse relationship between vitamin C intake and loss of cartilage.

Tissue damage and loss of cartilage can be caused by harmful substances that lead to oxidative stress. Oxidative stress is caused by an increase in the highly reactive molecules that react with other molecules in the cells and lead to tissue damage and cartilage loss.

Hence the anti-oxidants in vitamin C neutralize these harmful molecules and reduce the damage.

Ascorbic acid or vitamin C present in grapefruit were also found to involve in formation of both collagen and proteoglycans of cartilage tissue.

Collagen and proteoglycans are two major components of cartilage tissue which provides both cushion like function and lubrication for joint movement and their proper functioning is very important in osteoarthritis patients.

A study was published in Arthritis and Rheumatism which investigated the effectiveness of antioxidants like vitamin C in protecting against the development of osteoarthritis.

A difference in the progression of osteoarthritis was seen in the patients who were given vitamin C with those who were given non-antioxidant vitamins like B1, B6, niacin, and folate.

At the end of the study period, it was reported that if we increase our intake of vitamin C, then it can decrease the progression of osteoarthritis by decreasing the loss of cartilage. In contrast, this was not seen with patients who were given non-antioxidant vitamins.

What does this mean?
Patients who were given antioxidant vitamin (vitamin C) could experience a decrease in the inflammation and cartilage loss in contrast to those patients who were given non-antioxidant vitamins and did not get relieved of their inflammation.

2.Grapefruit helps in losing weight

It has been seen that being over-weight is a factor which can cause osteoarthritis. Obesity can put pressure on the knee joints which can injure them and cause tissue damage and cartilage loss.

Grapefruit is a low-calorie fruit and if taken 20 minutes before a meal, it can reduce your appetite. This is probably because of the water content in this fruit makes you feel fuller faster. The compounds in grapefruit reduce the level of insulin in the body which can help lose weight.

A study was published in Journal of medicinal food which studied the effectiveness of grapefruit in losing weight. In this study, 91 obese patients were given grapefruit juice and grapefruit capsules 3 times a day before each meals. The effects of grapefruit on metabolism were studied for 12 weeks.

At the end of the study period, it was observed that having half a grapefruit before each meal leads to significant loss of weight. Grapefruit was also reported to improve insulin resistance.

What does this mean?
Grapefruit is extremely effective accelerating in weight loss. By losing weight, a person can reduce the pressure he puts on his joints, especially knee joints and prevent knee injury. This can in turn prevent the development and progression of osteoarthritis.

3.Grapefruit helps in reducing inflammation

Lycopene is an organic pigment which gives grapefruit its pink colour. Lycopene is considered to be an effective anti-inflammatory agent. This is because it is known to act against and reduce the effect of pro-inflammatory mediator TNF alpha.

Hence it lycopene decreases the secretion of TNF alpha and other pro-inflammatory cytokines like IL-8 and IL-6 (small proteins that cause inflammation).

Grapefruit is effective in reducing inflammation in osteoarthritis because of the presence of lycopene. A study published in Molecular Nutrition and Food Research reported that lycopene showed anti-inflammatory properties by decreasing the secretion of pro-inflammatory compounds like TNF alpha.

Another study published in Die Pharmazie reported that lycopene has a significant effect in reducing the levels of pro-inflammatory cytokines like IL-8 and IL-6.

A study was conducted to detect the effect of naringin (a phytochemical synthesized by plant), well known falvanone glycoside found mainly in grapefruit and other citrus fruits on the key mediators (precursor which helps to connect) , namely T cell subsets (lymphocytes), CD4+GITR+expressing cells, CD4+CD25+Foxp3+(Treg), Th1/Th2cytokines  which are responsible for causing inflammation in arthritis. In the study Balb/c mice was treated with naringin in concentration of 20, 40, and 80mg for 14 days.

Results showed naringin treatment demonstrate significant decrease in the level of T cell, CD4+GITR+expressing cells, CD4+CD25+Foxp3+ (Treg), Th1/Th2cytokines as compared to the vehicle- treated and arthritic control mice indicating that the favanone glycoside (naringin) present in grapefruit possess anti-inflammatory properties and are very effective in arthritic treatment.

What does this mean?
This means that the lycopene in grapefruit is an amazing anti-inflammatory agent and should be used by patients who are suffering from osteoarthritis.

Dosage of Grapefruit for Osteoarthritis

The recommended dosage for grapefruit is based on the clinical trials that have been taken place to see its effectiveness. It is safe to consume 1/2 grapefruit daily. If you are taking juice, then the daily consumption should be 8 oz / 1 cup of grapefruit.

It was shown that the chemical present in the fruit furanocoumarins interferes with chemical which is naturally produce in humans stomach known as cytochrome P450 3A4.  These furanocoumarins are produced by plant tissue as a defence mechanism against foreign particles or predators.

There are number of drugs found, that interact with grapefruit such as statins group such as simvastatin, lovastatin and atorvastatin which are taken for treating cholesterol problems. Antibiotic like erythromycin, quinine, primaquinine used to treat bacterial infection, drugs used for cancer treatment like crizotinib, dasatinib etc. are found to become more potent when they come in contact with grapefruit.  Hence it very crucial to consult your doctor about your diet when you take specific medicines.
