Nutrition Changes Bring Relief to Rheumatoid Arthritis Sufferers
Nov. 19, 1999 (Boston) -- The debilitating effects of chronic rheumatoid arthritis can be softened -- if not always to a great degree -- by nutrition and exercise, according to Ronenn Roubenoff, MD, a nutritionist at the Tufts University School of Medicine. Roubenoff spoke to an audience of doctors here this week at a meeting of the American College of Rheumatology.
People with rheumatoid arthritis have twice the risk of dying compared to the general population, Roubenoff said. Reduced muscle mass contributes to that risk. The average 70-year-old has 30% less muscle than the average 25-year-old, said Roubenoff, and "if you lose 40%, you die."
Lack of muscle reserves, Roubenoff said, is one reason an elderly person who lands in the ICU after getting hit by a truck is so much more likely to die than a young person. "People who are acutely ill stop eating," said Roubenoff. But while fasting puts a normal, healthy person into a metabolic mode that burns fat and spares protein, under the stress of major trauma or illness, the body burns its own protein.
People with rheumatoid arthritis need to eat more protein than normal, healthy individuals, said Roubenoff, who recommends eating about 2.7 ounces of protein daily. That's roughly equivalent to one 4 ounce chicken breast or two servings of beans.
But simply eating more protein does not result in increased stores of protein in the body, said Roubenoff.
The problem is that the body stores protein as fat, because muscle is not being built. Resistance exercise -- which involves leg lifts and arm exercises using weights -- helps build muscle so that protein can be stored.
Also, certain important B vitamins are often deficient in people with rheumatoid arthritis, Roubenoff said. "The three we worry about are B6, B12, and folate. Supplements are important, particularly for elderly people, some of whom lose the ability to absorb B12 from food. "They can still absorb it from pills," said Roubenoff.
Much of the damage rheumatoid arthritis inflicts upon the body is probably the result of so-called "free radicals," said Roubenoff. Free radicals are fast-moving, destructive atoms -- created by smoking, inhaling pollutants, or being exposed to ultraviolet radiation from the sun. Free radicals circulate through the body, damaging cells, and are believed to cause many chronic diseases including rheumatoid arthritis, heart disease, cancer, Alzheimer's disease, and Parkinson's disease.
