A recent study in the American Journal of Clinical Nutrition found the average daily intake of two carotenoids (beta-cryptoxanthin and zeaxanthin) was lower (by 40% and 20% respectively) for arthritis patients than healthy subjects. Both of these carotenoids can reduce inflammation. Further analysis showed that the participants with the highest intake were about half as likely to develop inflammatory arthritis than those with the lowest intake. Two other popular carotenoids, lutein and lycopene, did not appear to protect against arthritis.
If you are looking for a way to protect your body against arthritis, it may already be a part of your normal breakfast routine—orange juice. To receive the protective, anti-inflammatory benefits of beta-cryptoxanthin and zeaxanthin include 7-9 fruits and vegetables in your daily diet. Foods high in these particular carotenoids include: oranges, papaya, tangerines, kale, collard greens, spinach, swiss chard, mustard greens, red pepper, okra and romaine lettuce.
