Avoid and conquer gout and kidney stones.

Do you suffer from kidney stones? Or maybe your aunt has a wild case of gout, and its

something that is always the centre of the conversation at family dinners? If so, this post

will be well worth the read! If not, this may prevent you or a friend from suffering from

either kidney stones or gout.


Oxalic acid is an organic compound composed of carboxylic acids. These are mild destructive

acids which may irritate the lining of the gut when consumed. They are found in a wide

range of foods, mainly plant foods. Many people are unaware of the importance of oxalic

acids in the body; they play a major role in the metabolism of plants and animals such as



Like any other compound, oxalic acid is required by our body in specific quantities. Too

much oxalic acid in the body may negatively affect the absorption of calcium due to the fact

that it binds to it and gets converted into indigestible oxalate salt, otherwise known as

kidney stones. In most cases the kidney stones are small enough to be passed out in the

urine. However, further development can lead to blockages in the urinary tract which can

cause severe pain in the abdomen area and in some cases lead to nasty and seriously painful



We only get about 20-40% of oxalates from the food we eat. The remaining percentage can

be made in the body from amino acids such as hydroxyproline in the liver, vitamin C or

glyoxylate in the red blood cells. Foods that contain high amounts of oxalate and may cause

over accumulation in the body are Rhubarb, chocolate, spinach, beet, almonds and other

nuts. However, in chocolate the oxalate content varies- it increases with the percentage of

cocoa present. For example 100% dark chocolate has a greater quantity than 80% dark

chocolate. White chocolate has a very low level of oxalate.




Purines are well-known for their role as building blocks in DNA and RNA, but they are more

than that. Purines have their own special receptor systems which allows them to connect

with the cell membranes of different cells within the human body. In the cardiovascular

system, they play a role in assisting with correct heart function through blood flow and

oxygen delivery. In the digestive system they assist in fluid secretion and the movement of

food through the gut. They are also quite important in other biological molecules such as



Purines, like oxalates are widespread in foods. They are commonly derived from offal, game

meat such as rabbit, venison or pheasant, oily fish, most seafood, meat and yeast extracts

such as marmite or Bovril and mincemeat.


Once in the body they are broken down to form uric acid. The formation of uric acid crystals

may increase the risk of developing gout, a type of arthritis, due to the deposition of these

crystals in the joints. This leads to stiffness and difficulty in movement. However, studies

show that people with high vitamin C diets are less likely to develop gout as vitamin C may

be a counteractive that inhibits uric acid from crystallising. If the kidneys become too

saturated with uric acid, they may bind with calcium and form salts that build up into kidney

stones. Hence too much purine will have similar effects to high oxalate levels in the body.

To prevent this from occurring, foods that contain high levels of oxalate and purine may

need to be eliminated or limited in the diet in order to control the build up of salts in the

kidney and the crystallisation of uric acid, which leads to kidney stones and gout
