Dietary Guidelines to prevent kidney stone

Mar 10 , 2015 | 2 min read

Drink plenty of fluid

Drink more fluid, especially water
Drinking water helps to flush out the kidneys and dilute stone-forming substances, making stones less likely to form.
Drink at least 3 litres, or 12 cups, of fluid daily. At least half of this should be water (soda, mineral, spring or plain tap water).
Have a cup of fluid (250ml) each hour during waking hours, and a large glass of water before going to bed. Drink a glass of water if you wake up during the night.
Spread out your fluid intake during the day.
Avoid strong black tea and orange juice, as these are high in oxalates.
Avoid grape fruit juice, cranberry juice (if more than 500ml/day) and sugary drinks. Drinking large amounts of sugary drinks (softdrink, cordial) can lead to weight gain. Choose diet or low joule drinks to limit weight gain.
Lemon juice is a good source of citrate which helps to prevent stones forming.
Drink 100ml of lemon juice daily (could be added to water).

Salt (sodium) increases the amount of calcium in your urine. Limit sodium intake to less than 2300mg per day.

Buy fresh food, or foods without salt - fruit, fresh vegetables, fresh meats, chicken, fish, eggs, porridge, rice, pasta
Most sodium (75%) comes from processed foods. Limit processed foods high in salt e.g. soup, sauces, gravy, crisps and snack foods.
“low salt” or “no added salt” foods are the best choices. Look for a sodium content less than 150 mg per serve as a guideline. Note that some “reduced salt” products can still contain high levels of sodium.
Do not add salt at the table or in cooking.

Reducing oxalate in your diet helps to reduce the amount of oxalate in your urine.
Limit intake of : rhubarb, spinach, silverbeet, beetroot, eggplant, sweet potato, celery, leeks
nuts, peanut paste
strong black tea, orange juice chocolate
wheat bran and wheat germ
berries (eg strawberries, blackberries), dried figs

Dietary calcium is important for your bones and teeth. Adequate dietary calcium intake is recommended.
Include at least 2-3 choices daily from the following list
250ml milk (eg trim, skim, full cream, calcium-fortified soy milk)
200ml high calcium milk eg Physical 200g (small tub) yoghurt
40g cheese (2 slices) 3 scoops ice cream

Limit protein from meat, seafood, fish, chicken, eggs to a moderate serve (120 -150g) daily (cooked) (note 60g meat = 2 eggs)

Do not take Vitamin C supplements (also known as ascorbic acid, calcium ascorbate)
Do not take Vitamin D supplements or cod liver oil

Eating foods higher in fibre can decrease the risk of stone formation by reducing the amount of calcium and oxalate you absorb
Choose wholemeal and wholegrain breads, flour, cereals, pasta, biscuits and crackers
