Avocado may be considered a functional food for the prevention and treatment of osteoarthritis, some scientists suggested.
Avocado is a commercially valuable fruit cultivated in tropical climates throughout the world.
The fruit is a green-skinned, pear-shaped fruit that ripens after harvesting and is native to the Caribbean, Mexico, South America, and Central America, belonging to the flowering plant family Lauraceae.
Osteoarthritis is a group of diseases involving progressive denegation of joints, including articular cartilage and subchondral bone.
According to the statistic, osteoarthritis (OA) is the most common joint disorder in the US, affecting over 10% of men and 13% of women aged 60 years or older. The disease can also affect the younger population, after a traumatic injury.
.
Epidemiological studies suggested that symptoms progress slowly and contribute to work disability and reduced quality of life.
Dr. Hofmann S, the lead scientist in the team of arthritis in the examine the mechanical causes of osteoarthritis in young adults suggested that certain conditions such as femoroacetabular impingement (a condition in which extra bone grows along one or both of the bones that form the hip joint) are a very common cause of secondary osteoarthritis (OA) in the young adults" and "
It is an important co-factor in the better recognized pre-arthritic deformities such as residual hip dysplasia (RHD), Perthes disease and slipped capital femoral epiphysis (SCFE)".
These results clearly indicated genetic mutation and mechanical deformity are major causes of osteoarthritis in the younger adult besides athletic injury.
Some scientists proposed that the development of femoroacetabular impingement may be a result of a repetitive injury to the proximal femoral physis that occurs during a critical period of development.
With an aim to find a natural ingredient for the prevention and treatment of osteoarthritis, a disease associated with the progressive denegation of joints, researchers at the Universities of Exeter and Plymouth assessed the anti-OA of the compounds Avocado/soybean unsaponifiables (ASU) which have shown some promises for OA.
By searching the database of medical literature, researchers found 4 randomized, placebo-controlled, double-blind trials of ASU.satisified the guideline and criteria.
The doses per day in the 4 studies are in the range between 300 mg and 600 mg.
3 out of 4 studies suggest that ASU is effective for the symptomatic treatment of OA.
Furthermore, the Hôpital Léopold Bellan launched a follow-up study to investigate the efficacy of preparations with avocado-soybean unsaponifiables (ASUs) in osteoarthritis (OA) patients in the hip, included 163 patients, 102 men and 61 women (mean age 63.2 +/- 8.7 years).
Participants in the study are patients with regular painful primary OA of the hip (European League Against Rheumatism 1980 criteria) and a joint space still > or = 1 mm were selected entered a prospective, multicenter, randomized, parallel group, double-blind, placebo-controlled trial of 2 years duration.
The ASU treatment group showed a lesser joint space loss compared to the significantly greater loss in the placebo group.
The clinical parameters in the 2 groups did not differ significantly throughout the study.
These results indicated a significant effect of ASU against the progression of joint loss in OA patients.
Dr,. the lead scientists said, "SU significantly reduced the progression of joint space loss as compared with placebo in the subgroup of patients with advanced joint space narrowing".
Taken altogether, avocado-soybean unsaponifiable's (ASUs) may have a profound effect in reducing the symptoms and progression of osteoarthritis.
