Arthritis: Seven foods that claim to affect painful joints with no scientific evidence.

ARTHRITIS causes great pain and discomfort to the affected joints, but can be improved by eating the right foods. However, there are many claims surrounding what you should eat to help ease pain and inflammation that are not backed up by science.

People often hear of various home remedies which can make your arthritis better, however there is often no evidence to support some of these claims.

The Arthritis Foundation lists seven food myths claiming to affect the symptoms of arthritis.


Citrus is blamed for inflammation because of acidity, but citrus fruits are rich in vitamin C and antioxidants and have anti-inflammatory benefits.

You should remember, however, that grapefruit juice can interact with certain arthritis medicines.


Some people report feeling better when they ditch dairy, but studies show that it can be pro- or anti-inflammatory for different people, and may lower gout risk.

Unless you’re lactose intolerant or have a dairy allergy, these products don’t have to be off limits, but you should choose skim and low-fat options.

Cider vinegar

Some people claim drinking diluted cider vinegar can help improve arthritis, while others claim you should combine it with honey or baking soda.

However, the anti-inflammatory benefits are not backed by science, according to the Arthritis Foundation.

Raw diet

Eating only raw fruits and vegetables has also been claimed by some people as curing their arthritis.

Although in one study participants reported pain relief, half of them quit because of nausea and diarrhoea.

Gelatin and collagen

Gelatin is made from collagen, but there is no actual proof that eating jelly eases joint pain.

According to the Arthritis Foundation, study results about taking collagen hydrolysate or undenatured collagen for osteoarthritis pain “are mixed but look promising”.


Some people dissolve fruit pectin - a gelatin-like substance used in jams and jellies - in grape juice. But there’s no scientific evidence that this solution relieves arthritis pain.

Pectin is a type of dietary fibre, which has health benefits, but adding it to sugary grape juice can hinder weight loss.

Alkaline diet

As acidic foods, like meat and processed foods, are blamed for inflammation, some people claim that eating ‘alkalising’ foods, like fruits, vegetables and specific grains, will restore the body’s proper pH balance.

However, many factors affect pH, such as how your kidneys work, so the claims could be misleading.

“But you can’t go wrong with eating fewer processed foods and more fruits and veggies,” said the Arthritis Foundation.
