Minerals
in Alkaline Based Foods
Alkaline based foods
leave behind an ‘alkaline ash’ residue
in the body, once they have been eaten and digested. This alkaline ash
is
dependent upon the mineral content of the food.
The minerals potassium, calcium, magnesium,
sodium, copper,
zinc, iron and silver are all alkaline and so generally,
foods containing these
are classed as being alkaline.
In contrast, the minerals
sulphur,
chlorine, phosphorus,
fluoride, silicon and iodine are acidic and therefore
foods containing these
have an acidic effect on the body when consumed.
See my Alkaline
Foods List for a comprehensive guide to alkaline foods.
Are Fruits Alkaline
Foods?
It is important to make a
note of the following important
point, however, relating to fruits:
Many fruits contain
alkaline minerals but are not actually
classed as being alkaline foods. This is because the ‘good’
effects of
the alkaline minerals are outweighed by the ‘bad’ acidifying effects of
the
high sugar content of the fruit. For example, think of how sweet a
pineapple is: The large amount of sugar (even though it's naturally
occuring) means that pineapples
are acidic foods.
Fruits are not as
acidifying as processed foods or meat and
dairy products because they still contain a high water content and
alkaline
minerals, but they do need to be eaten sparingly and viewed as
moderately
acidic foods because of their sugar content.
The only truly alkaline
fruits are avocadoes, tomatoes (kind
of like vegetables anyway aren’t they), lemons, limes and grapefruits.
