The best foods for arthritis symptoms revealed in new research

Osteoarthritis is the most common of the more than 200 forms of arthritis, affecting more than 20% of the population. Unfortunately, there are currently no effective treatments or approved drugs for this disabling condition, which causes the joints to become painful and stiff. Some new drugs are in the pipeline, but it will be years before they are tested in clinical trials and approved by regulators.

Many people with osteoarthritis take a bewildering variety of dietary supplements, the favourites being glucosamine and chondroitin sulphate, but the evidence doesn’t actually support their use. However, we are happy to report that our recent review of published evidence shows that eating the right foods, combined with moderate low-impact exercise, can benefit people with osteoarthritis.

Firstly, losing weight and exercising are the most significant things that osteoarthritis patients can do to ease their symptoms. Weight loss reduces the load on the joints and lowers the level of inflammation in the body, reducing arthritis pain. Exercise helps you to lose weight while keeping your muscles strong, which helps protects the joints and makes it easier to move around. So overweight and obese people with osteoarthritis should find ways to lose weight that include exercise aimed at increasing their muscle strength and enhancing their mobility.

Oily fish

Eating certain foods can also help improve patients’ symptoms and reduce their daily joint pain. Evidence shows eating more oily fish such as salmon, mackerel and sardines can improve pain and function in arthritis. This is because the long-chain omega-3 fatty-acids they contain reduce the amount of inflammatory substances the body produces. Fish-oil supplements of 1.5g per day may also help.

But eating fish oils alone may not be enough. It is also important to reduce the long-term consumption of fatty red meats and replace saturated animal fats with vegetable oils such as olive and rapeseed.

Lower cholesterol

Osteoarthritis patients are more likely to have raised blood cholesterol, so eating in a way that reduces blood cholesterol can help, as well as improving general cardiovascular health. Reducing the amount of saturated fat you eat and increasing the amount of oats and other soluble fibres will help to reduce cholesterol.

Other specific ways to reduce blood cholesterol include eating 30g a day of nuts, 25g a day of soy protein from tofu, soy milk or soy beans, and eating 2g a day of substances called stanols and sterols. These are found in small amounts in plants but the easiest way to consume them is in fortified drinks, spreads, and yogurts that have these substances added to them.
