Carotenoids Arthritis Risk Cut
Just drink a glass of orange juice a day, the risk of developing forms of inflammatory arthritis. Researchers found at the University of Manchester in Britain in the American Journal of Clinical Nutrition (August 2005) that certain carotenoids, including beta-cryptoxanthin and zeaxanthin reduce the risk of developing arthritis. However, two other carotenoids lutein and lycopene, did not appear to have the same protective effect against arthritis.
Study: Are fruits and vegetables reduce the risk of arthritis?
The researchers analyzed data from a study with 25,000 participants to determine whether carotenoids affected risk of arthritis. The study participants have a diet diary and were followed between 1993 and 2001, new cases of inflammatory polyarthritis, defined as synovitis (inflammation of the lining of the joint), to identify the two or more mixed groups.
The results of the study
Eighty-eight participants who developed arthritis, were found. They were compared with 176 healthy people as controls. Had 20% lower developed The average daily intake of zeaxanthin in the group arthritis patients than in controls. The average daily intake of 40% beta-cryptoxanthin was lower in patients who had developed arthritis in the control population.
The upper third of the intake of zeaxanthin and beta-cryptoxanthin less likely to develop inflammatory arthritis than that in the lower third of the inlet.
What is Beta-cryptoxanthin?
Beta-cryptoxanthin is classified as pro-vitamin A carotenoids. In the body can lead to an active form of vitamin A. Vitamin A is known to be important for the function of the immune system, and health of the skin and bone are converted. Beta-cryptoxanthin is found in fruits and yellow or orange vegetables.

What fruits and vegetables are rich in beta-cryptoxanthin?
According to NutritionData.com, a full list of the 467 richest beta-cryptoxanthin food shows:
- Peppers, pumpkins, squash and vegetables with the highest levels of beta-cryptoxanthin per serving.
- Persimmons, tangerines, papayas and fruit with the highest levels of beta-cryptoxanthin per serving.
What zeaxanthin?
Zeaxanthin is another carotenoid with antioxidant power. After www.5aday.org, food sources of zeaxanthin are green vegetables, fruits, yellow / orange and vegetables.
Research at the University of Manchester supports previous studies that have concluded that dietary antioxidants such as beta-cryptoxanthin and zeaxanthin as well as vitamin C may be associated with a lower risk of arthritis.
