There are two essential nutrients that are often lacking in the diets of many people and as you get older your diet and lifestyle in general becomes increasingly important to your health.
So make sure that you get adequate intakes of vitamin D, selenium and Omega-3 essential long-chain polyunsaturated fatty acids (PUFAs).
Essential Omega-3s are found in oily fish and many seeds as well as, certain vegetables such as broccoli.
These essential nutrients are readily available in supplement form, which may be the most reliable way to make sure you have enough of the substances you need to prevent and treat arthritis.
Before you invest in a good supplement, choose to eat oily fish three times a week (not everyone's cup of tea!) or decide to eat oysters or mushrooms regularly for their high selenium content, you will ask if these in fact do work to treat and prevent arthritis.
The good news is that research has shown that such nutrients do slow down the loss of cartilage and also, as in the case of rheumatoid arthritis help to control an overactive immune system.
Arthritis is also helped and prevented by a wonderful substance called Glucosamine sulphate easily available in capsule and tablet form, often with another substance called Chondroitin.
Glucosamine is naturally present in cartilage and the synovial fluid.
Glucosamine sulphate may help to strengthen cartilage and has been shown to be particularly effective in arthritis of the knee.
Taking such well tried supplements as well as pursuing a diet rich in minerals and vitamins to promote good health as you get older will also lower your need for conventional drugs such as non-steroidal anti-inflammatory agents.
Other dietary advice is to cut down on acidic foods, replacing with tropical fruits such as pineapple and papaya which have been found to be helpful for arthritis sufferers.
Pineapple in particular contains Bromelain, excellent for arthritis - again especially of the knee.
And if you don't like pineapple you can get good Bromelain supplements.
Maybe a combination of the lovely fruit and a supplement will give you all the benefits of the anti-inflammatory power of Bromelain which is often better tolerated than many conventional drugs.
