He needs to make sure he is fully hydrated.
Multiply his weight in kilos by 0.033 to find how many litres of water he needs a day.
His urine should be light yellow..NOT dark or clear.
When the body is dehydrated one of the first place it scavenges water from is joint cartilage along with the intestinal tract...is he also constipated?
Rehydration can take months and even years if it is chronic.
He needs to avoid ALL GRAINS AND PRODUCTS MADE FROM THEM.
If he has a grain intolerance the body can attack the synovial lining of the joints because the protein in gluten is so similar to the joint lining that the immune system can't tell the difference.
I would advise an Omega 3 fish oil supplement such as Higher Nature as they are filtered for toxins.
He needs to avoid ALL dairy because if he is gluten intolerant he WILL be dairy intolerant as they go together.
Avoid ALL procesed sugar.
Eat plenty of organic meat,the saturated fat will do him good.
Go to www.ppssuccess.com and do the free Metabolic Typing test and then eat all meals to Metabolic Type.
Try the above for 3 weeks and see if his symptoms improve.
His problem could be caused by many things but the above is a good starting point and is relatively easy to do.
Hope this helps
