It's the latest fad diet. The promotion of this "Alkaline
diet" is fervently done by many female stars, the very thin head that
Victoria Beckham has tweeted the benefits to subscribers (almost seven
million!).
Alkaline diet: what is it?
Alkaline Diet (alkaline diet) restore the
acid-base balance in the body
The acid-base balance
The dogma of the alkaline diet, which is also called
"anti acidic diet" is to restore the acid-base balance in the body.
An acid is a substance which releases hydrogen ions (H +),
residues of energy metabolism. These H + ions are neutralized by a basic
substance (or alkaline, it is the same thing).
The indicator of the balance between the two is the blood
pH or possibly that of urine.
pH:
The pH is the "potential hydrogen". It measures
the chemical activity of hydrogen ions (H +). Established on a scale from 0 to
14, it is neutral at about 7. More is below this number, the more acid. And,
vice versa, the more it is over, the more alkaline. The normal pH of blood and
cellular fluids is between 7.35 and 7.45: it is very slightly alkaline and very
stable.
This balance between the acidic and basic substances -
which are then eliminated by the kidneys in urine - is normally and permanently
in the body.
Except in rather dramatic circumstances in which we are
dealing then with acute metabolic acidosis when the system is overwhelmed and
the kidneys can not eliminate excess acids. This can occur in inadequately
controlled diabetes, fasting too long, severe diarrhea, poisoning with aspirin
(which is salicylic acid).
But in the case of the alkaline diet, it is not to change
the pH of the blood, because it is stable, but simply to reduce acidifying
foods over and increase alkalizing foods instead.
Do you eat too acidic?
Foods are classified according to their acidifying or
alkalizing protein and minerals and also the nature of their metabolic waste.
There are several detailed classifications acidifying or
alkalizing foods that raise controversy.
Acidiants food:
For acidifying foods, the consensus is on meats and all
foods rich in animal protein not only contain acidifying minerals (chlorine,
sulfur and phosphorus), but they also deliver a lot of waste acids.
We find the same consensus on industrial products, sweet
products, alcoholic and caffeinated drinks. All that you acidify A LOT!
Alkalifying food:
As for alkalizing foods, everyone agrees on fruits and
vegetables because they contain alkalizing minerals: magnesium, calcium, sodium
and potassium, but very little protein, chlorine, sulfur and phosphorus.
As for other foods (cereals, dairy products, fats), they
are more or less alkalizing or acidifying.
How to know if you eat too acidic and is
it dangerous?
Supporters of alkalizing diet recommend measuring the pH of
the urine, or several times a day.
How?
Peeing on a test strip (litmus paper, pharmacy) that
changes color according to acidification. The more it is red, more urine is
acidic.
If your diet is too low in alkalizing products your body to
keep your acid-base balance, must go to pump your basic minerals and mainly in
the calcium from your bones and teeth for that is that there has in stock.
According to some, this would be the explanation for this
disease that is becoming more common osteoporosis and fragile bones. It has
already been shown that a diet rich in fruits and vegetables (magnesium and
potassium) favored bone density.
According to fans of alkalizing diet, the majority of our
present ills, large and small, come from what we ate too acidic. Fatigue
stress, to weight gain, cancer and cardiovascular disease, all of this comes
from our over-acidification!
Is the alkaline diet dangerous?
In a hard-alkaline diet, you have to remove or
significantly reduce meats, fish, meats, eggs, all processed products,
desserts, drinks containing caffeine and alcohol which are mostly acidifying.
Must be reduced more moderate dairy and grains.
You have to eat fruits, vegetables, almonds and seeds,
seasoned with spices and herbs, because all these foods are alkalizing.
How to practice good "Alkaline
Diet"?
The first and basic rule is to eat lots of vegetables and
fruit at every meal: you are then sure to have a max of alkalizing products.
The second is to forget industrial products (like ready
meals, pizzas, etc.), products and sugary drinks. And maximum braking on
alcohol and coffee.
The third is to reduce its consumption of red meat and
charcuterie: If you are a fan of the big daily steak, eat it two or three times
a week and replace with fish and eggs, less acidifying. If you start each meal
with a good piece of pie, replace it with raw vegetables or vegetable soup.
The fourth is to leave room for dairy products and grains
at each meal.
All this is very similar to a balanced diet, one that we
recommend here forever and is the key to weight loss!
