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?
From ... to "deacidify"
because a diet too acidic would be bad for health.
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 (e) 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!
