A randomized controlled study finds that a diet low in carbs can relieve pain for people who have knee osteoarthritis.
Seniors with knee osteoarthritis may benefit from switching to a low-carb diet.

Osteoarthritis is the most widespread form of arthritis among older adults in the United States.
Knee osteoarthritis, in particular, affects about 10 percent of men and 13 percent of women ages 60 and above. According to some estimates, the condition affects 40 percent of people over the age of 70.

There is currently no cure for knee osteoarthritis, which can cause joint swelling, stiffness, and even severe pain.
Doctors often prescribe pain relievers, such as acetaminophen, opioids, or nonsteroidal drugs, to help alleviate symptoms. Knee replacement surgery is also an option.

However, these treatments are either invasive or could cause a range of unwanted side effects. This is why researchers have decided to investigate whether dietary interventions could relieve some symptoms and signs of knee osteoarthritis.
Studying the benefits of a low-carb diet
The researchers found that the low-carb diet reduced functional pain levels and levels of self-reported pain. The benefits were particularly noticeable, in comparison with the low-fat and regular diets.

The diet significantly reduces pain
Among people who consume meat, popular low-carb options include “lean meats, such as sirloin, chicken breast, and pork.” Fish and eggs are also low in carbs, as are leafy green vegetables, including kale and spinach.

Cauliflower, broccoli, nuts, seeds, nut butter, coconut oil, olive oil, and dairy products are also good low-carb options. For those who wish to avoid animal products altogether, tofu and tempeh are great low-carb alternatives.
