Most people think that eating fruit along with their
main meals is a good way to stay healthy. Without
properly understanding the body's digestive cycle
over a 24 hour period, many people consume fruit
in a manner that will bring them little nutritional
benefit. Having lots of fruit with your main meals
or eating it as a desert after meals is not the ideal
way fruit should be eaten.
In order for your body to get the maximum benefit
of eating fruit you should follow the guidelines
given below.
It is best to eat fruit on an empty stomach. You
can do this at any time during the day.
After eating fruit , you should leave around 30
minutes before consuming any foods besides
fruit .
After you have had a proper meal, leave at least
three hours before you eat any fruit . This will
ensure that the previous meal has left the
stomach.
You should try your best to consume mainly
fruit before noon.
Avoid eating fruit along with other foods. Fruit
should best be eaten on its own.
Never eat fruit as a desert, after a meal. This is
is wasting much of the fruit's benefits.
Avoid fruits like bananas and avocados in the
morning because they are heavy foods and tax
the digestive system in the morning. These can
be eaten after noon when the body is in the
appropriate digestive cycle for such foods to be
eaten.
If you feel hunger during the morning, eat fruit
and you can keep eating portions of fruit until
your blood sugar level goes back to normal,
resulting in your hunger disappearing.
Eat only organic fruit to the best of your ability.
Avoid processed, cooked, or canned fruit . These
contain large amounts of sugars, additives and
other undesirables.
Fruit is digested in the intestine and not in the
stomach. It is also rapidly digested and goes
through the digestive system in around half an
hour. The brain runs on glucose and fruit is the
most efficient source of blood sugar. With sufficient
fruit consumption your blood sugar levels
normalize, allowing your body's hunger
mechanism to be properly regulated and thus
avoid over-eating and obesity .
