Antioxidants, Not Weak in the Knees

As someone who recently took up Yoga, I can tell you—KNEE STRENGTH IS IMPORTANT! And here’s a good way to help your knees stay strong. New research claims consuming plenty of antioxidants may protect against knee arthritis. Reuters reports:
Australian researchers found that middle-aged adults with higher dietary levels of vitamin C were less likely to develop certain bone abnormalities that contribute to knee arthritis.


The findings "highlight the potential of diet to modify the risk of osteoarthritis," they report in the online journal Arthritis Research & Therapy. Dr. Yuanyuan Wang of Monash University in Melbourne led the research.

The subjects were 293 men and women who were middle-aged, healthy and free of knee pain at the start of the study. At that time, they completed detailed questionnaires on their diets; 10 years later, their knee tissue was examined using MRI scans. All of the nutrients were obtained through food, rather than from supplements.

In general, Wang's team found, the higher a person's dietary levels of vitamin C at the start of the study, the lower the risk of certain bone changes 10 years on. The same was true when the researchers looked at overall consumption of fruit, a prime source of vitamin C.

Certain carotenoids, such as the lutein and zeaxanthin found in green vegetables, were also related to a lower risk of cartilage defects in the knee.
Antioxidants are no joke. Dr. Fuhrman talks about their power in Prevent Deficiencies with Plant-Based Nutrition:
The most dramatic finding in nutritional science in the last fifty years is the power of plant-derived phytochemicals to affect health. Phytochemicals, along with the rich assortment of powerful antioxidants found in unrefined plant foods, fuel a defensive system that removes toxic cellular metabolites that age us. Phytochemicals also are required for maintenance and repair of our DNA.


Cancer may be promoted by toxic compounds, but we have cellular machinery, fueled by phytochemicals, to detoxify and remove noxious agents and to repair any damage done. Our body is self-healing and self-repairing when given sufficient nutrient support to maximize efficiency of protective cellular machinery. But, only when we consume large amounts of green vegetables and a diversity of natural plant foods can we maximize phytochemical delivery to our tissues.
