PREVENTION & DIETARY RECOMMENDATIONS
Prevention and Dietary Reccomendations
Drinking plenty
of fluids will help to prevent any type of kidney
stone. You should drink at least 3 litres / day, or
enough to make your urine clear rather that a yellow
colour, also avoiding excessive sodium and alcohol.
Doing Exercise regularly and
stay active may reduce risk factor of kidney stones.
A recent study
on calcium intake and kidney stones (Curhan et al.,
1993) found that people with high dietary calcium
intake were less likely to have stone reccurence
than those who followe a low-calcium diet. The
mechanism is the dietary calcium binds oxalate in
the gut, reducing urinary oxalate concentration.
Dietary
recommendations for some types of kidney stone:
v
For Calcium
Oxalate Stones > Limit intake of oxalate-rich foods,
like nuts, chocolate, tea, rhubarb, asparagus,
spinach, peanut butter, leeks, wheat germ, collards,
beets, swiss chard,and okra. Consume adequate
dietary calcium ( taken with meals they are likely
fine; taken alone they may contribute to the
increased urinary calcium). Avoid vitamin C
supplements. Vitamin C is not recommended in
quantities above the RNL as ascorbic acid is a
substrate for oxalate synthesis.
v
For Uric
Acid Stones > Avoid excessive intake of animal
protein, purine-rich foods, like organ meats, fish
and poultry and also alcohol.
For all types
of stones, generous fluid intake
(3L/day) is recommended to
prevent recurrence.
