Recent research by a New Zealand University team into colon
cancer has uncovered a very interesting phenomenon that sheds
light on why colon cancer is almost non-existent in the Maori
race. Naturally this fact created a spin-off from the original
study because if the reason why the indigenous Maori people
avoided this disease could be found they would gain precious
information to help the constant fight to prevent colon cancer.
Initially they looked at diet and discovered that both red and
purple berries and fruits formed a higher proportion of their
diet than it did with non-indigenous New Zealanders. Based upon
common practice they were aware of the anti-oxidant value of
fruit and assumed that non-Maori people gained the same amount
of anti-oxidants from other fruit and vegetables. This appeared
to cancel out any benefit the Maoris gained by having a diet
high in red and purple fruits and vegetables. That was until
they decided to check anti-oxidant levels individually.
The results of the independent checks of anti-oxidant levels
across a wide range of fruits and vegetables discovered that
rather than these levels being the same, as commonly thought at
the start of the experiments, they vary widely. For instance
fruits with red or purple skins like berries, plums, red apples
and even red skinned sweet potato have around four times the
anti-oxidant levels of other fruits and vegetables. At this
point the entire project started to make sense and the higher
levels of ant-oxidants in a traditional Maori diet pointed to
the reason for such low levels of colon cancer within the race.
The research continues today but based upon these findings there
is strong reason to eat more strawberries, raspberries,
redcurrants, cherries, plums, red apples and sweet potato in our
daily diets. In fact any fruit or vegetable with a red or purple
skin contains around four times the anti-oxidant level of other
fruits and vegetables and therefore should be utilized in our
diets for health reasons.
Somebody is bound to raise the question of whether frozen is as
a good as fresh fruit. Here I can only give a personal opinion
and state that whenever we cook, or freeze, foodstuffs we change
the chemical make-up of the food and therefore it is unlikely to
be the same as eating it fresh and uncooked. But, if frozen is
all that is available then I guess its better than nothing.
