Your
kidneys play a vital role when it comes to filtering waste out of the body.
Each day, these organs on either side of the spine, filter more than 200 quarts
of blood and 2 quarts of waste products before it’s flushed out of the body via
urination.
Obviously,
healthy kidneys are essential for proper detoxification. However, certain foods
can cause kidney stones and keep these organs from functioning optimally. Here
are ten foods that encourage kidney stone development…
1. Excessive Caffeine
Too
much caffeine—in the form of coffee, tea, and soda—can stress out the kidneys
and lead to the development of kidney stones due to higher calcium levels in
the urine, and even kidney failure due to the stimulant qualities that can
cause organ exhaustion.
Too much of anything truly is bad for you. One of the reasons why cups of coffee with saucer look appealing is because the amount of coffee is small. It's not a large cup, say, from Starbucks or Pete's Coffee. One guy in a forum I subscribe to advocated 6 to 8 eggs, cooked but as close to raw as possible, to restore nerve and hormonal communication between organs. Okay, sounds good. Cholesterol can do that, but there seemed to be little consideration for the amount of protein consumed in such large quantities of eggs. Moderation really is the best rule of thumb, even if it is moderation in those things that are bad for you. I love my coffee. I like it at different times of the day, not just in the morning. I tend to drink coffee in the morning to warm me up not wake me up. Once I am up I don't need a stimulant; I generally need warmth. Later in the day, I like the occasional cup of coffee for taste. I love the taste. But I do have to be careful drinking too many cups a day. It has an aging and drying effect, particularly if the excess coffee consumption is exhausting my kidneys.
When in Denver this past summer, I was drinking a brand called DazBog. I liked it because it had a deeper, richer coffee taste. At times it did taste like burnt cigarette ashes but it was still good. I liked it better than Starbucks, which even their dark roast cannot match to the richness and depth of DazBog. I wished I drank better-tasting coffee. For the longest time I was drinking instant coffee from Whole Foods that wasn't bad.
2. Rhubarb
If
kidney stones are hereditary, you should steer clear of foods that contain
oxalates (the material that makes up the actual stones). Rhubarb is one food
that’s particularly high in oxalates.
On oxalates, the verdict is still out:
The formation of kidney
stones containing oxalate is an area of controversy in clinical nutrition with
respect to dietary restriction of oxalate. About 80% of kidney stones formed by
adults in the U.S. are calcium oxalate stones. It is not clear from the
research, however, that restriction of dietary oxalate helps prevent formation
of calcium oxalate stones in individuals who have previously formed such
stones. Since intake of dietary oxalate accounts for only 10-15% of the oxalate
that is found in the urine of individuals who form calcium oxalate stones, many
researchers believe that dietary restriction cannot significantly reduce risk
of stone formation.
In addition to the above
observation, recent research studies have shown that intake of protein,
calcium, and water influence calcium oxalate affect stone formation as much as,
or more than intake of oxalate. Finally, some foods that have traditionally
been assumed to increase stone formation because of their oxalate content (like
black tea) actually appear in more recent research to have a preventive effect.
For all of the above reasons, when healthcare providers recommend restriction
of dietary oxalates to prevent calcium oxalate stone formation in individuals
who have previously formed stones, they often suggest "limiting" or
"reducing" oxalate intake rather than setting a specific milligram
amount that should not be exceeded. "Reduce as much as can be
tolerated" is another way that recommendations are often stated.
3. Artificial Sweetener
You
probably use artificial sweetener in your coffee as opposed to sugar in order
to cut calories. And maybe you opt for diet soda for the same reason. However,
studies show that non-caloric sweeteners impair kidney function if consumed
long term. So it’s best to opt for natural sweeteners like honey, stevia or
agave instead.
Aspartame, which exists in a few
artificial sweeteners, is the worst food you can put into your system. Find
out why.
4. Meat
Animal
proteins are also linked to kidney stones and organ damage. And those who
consume a high-protein diet put particular stress on their kidneys because
protein waste is difficult to eliminate form the body efficiently. Meat is also
high in uric acid, a common cause of kidney stones.
5. Sardines
If
you’re prone to kidney stones, you’ll also want to curb your diet of any foods
that are high in purines (an organic compound that boosts aroma). Sardines are
extremely guilty of purine content so don’t pop that can top.
6. Salt
A
healthy amount of sodium in your diet is necessary for healthy fluid levels.
However, adding salt to your diet—via the salt shaker or processed
foods—encourage water retention retaining water, meaning excess sodium isn’t
flushed out of the body and the kidneys and blood pressure are put in jeopardy.
7. Carbonated Drinks
Carbonated
drinks (i.e., soda, energy drinks, and certain bottled juices) will heighten
the risk of developing kidney stones and even put you at risk for kidney
disease. As an alternative, if you can’t drink your water plain, use frozen
berries, slices of citrus, or a splash of natural cranberry or pomegranate
juice.
8. Some Leafy Greens
We’ve
already discussed that kidney stones form due to a build-up of calcium oxalate.
And those with a high level of the chemical compound in their urine are more
prone to stones. That’s why it’s vital to stay clear of some leafy greens—such
as spinach, okra, and Swiss chard.
9. Dairy Foods
We
eat dairy products because they are high in calcium to build strong bones.
However, for those prone to kidney stones, calcium is not a friend. In fact, it
increases the excretion of calcium in the urine, making waste elimination more
difficult and encouraging kidney stones to form.
10. Processed Foods
Most
processed foods, like that bag of chips you’re eating, contain genetically
modified ingredients—such as corn, soy, rice, and canola—to protect crops from
pests resistance and herbicides. However, these products impair healthy kidney
and liver function, encouraging kidney stones to form.
