Whether
we are healthy or somehow indisposed, we’ve learnt from the
kindergarten that to maintain good health, we must eat daily portions of
fruits and vegetables. Indeed, “Eat your fruits and vegetables” is one
of the nursery rhymes the average child learns once he starts school,
and rightly so.
This is because regular consumption of fruits and vegetables leads to superior health.
Nutritionists also say diets rich in
fruits and vegetables may reduce the risk of some types of cancers,
stroke and other chronic diseases like Type 2 diabetes and, perhaps,
heart disease.
Fruits and vegetables also provide
essential vitamins and minerals, fiber, and other substances that are
important for good health. Better still, most fruits and vegetables are
naturally low in fat and calories and are filling. As such, it is
virtually impossible to get fat on a diet of fruits and vegetables.
Consultant endocrinologist and
diabetologist, Dr. Afokoghene Isiavwe, recommends that half of your
plate during each meal should be fruits and vegetables. She also says
your age, sex and activity level will determine how many calories you
need each day, while your calorie needs determine how many fruits and
vegetables you should eat.
The Centre for Disease Control and
Prevention recommends eating fruits and vegetables of different colours,
which it says gives the body a wide range of valuable nutrients like
fibre, foliate, potassium and vitamins A and C.
For the aging brain, fisetin, a unique
flavonoid compound found naturally in many fruits and vegetables, is
very useful. According to a publication in the journal Neuroscience
Letters, fisetin is present in strawberries, blueberries and the skin of
cucumbers. A wealth of scientific research says a diet packed with raw
fruits and vegetables can help prevent amyloid plaque formation in the
aging brain and helps to maintain normal memory processes.
For the beauty-conscious, a University of
St. Andrews, UK, study reveals that fruit and vegetable intake is also
associated with healthy glowing skin. According to the research
published in the American Journal of Public Health, carotenoids in the
fruits are responsible for the healthy skin glow. Carotenoids are the
red, yellow and orange pigments found in fruits and vegetables. They
deposit under the skin and provide several health benefits.
Again, in January, scientists at the
Harvard School of Public Health reveal that individuals who consume
antioxidant-rich fruits and vegetables on a regular basis are also more
optimistic about the future.
The study assessed the blood
concentrations of nine antioxidants in 1,000 male and female
participants between the ages of 25 and 74. During the assessment, the
participants completed a questionnaire about their attitudes on life.
The scientists found that the most
optimistic participants each had up to a 13 per cent increase in blood
concentrations of carotenoids, compared to those who were less
optimistic. Moreover, they also found that the participants who consumed
fewer than three servings of fruits and vegetables per day were
considerably less optimistic than those who consumed more than three
servings per day.
Again, a series of studies co-authored by
Professor Sarah Stewart-Brown at the University of Warwick showed that
individuals who consumed the most fruits and vegetables were least
likely to suffer from depression, anxiety, and other mental issues. They
also tended to be more satisfied with their lives.
“Wonderful news!” you dare exclaim. And
for those who daily load up on fruits and veggies, it’s time to give
yourself a thumb-up.
Perhaps not so quickly, I’m afraid. This
is because nutritionists have also expressed concerns about certain
unethical practices that go with planting and harvesting of fruits,
especially in the laboratories where all sorts of experiments are
carried out in the name of increasing yields. At the end of the day,
foods — including fruits — turn out to be what they ought not: dirty.
Dirty, not in the sense of soiled with dirt, but because they are
unsafe.
These days, it is common to encounter
‘seedless’ fruits on supermarket shelves. They are mostly imported —
from the Middle East, the United States, and sundry other places. They
are engineered in the laboratories and are generally referred to as
‘genetically modified.’
Those that are not genetically modified
are saturated with pesticides in the process of planting, tending and
harvesting. Worse still are fruits shipped across the continents. They
may be infested with different bacteria that can cause serious health
risks.
In fact, experts say different types of
dangerous bacteria are the single highest cause of food-borne illnesses,
as they can cause the spread of salmonella, a bacterium that causes
food poisoning and typhoid fever in humans; or shigella, a bacterium
that causes dysentery.
Nutritionists give a list of fruits
usually called the ‘Dirty Dozen,’ and they include apples (which contain
more than 40 different pesticides, as fungus and insect threats prompt
farmers to spray various chemicals on their orchards); celery (more than
60 pesticides); strawberry (nearly 60); peaches (nearly 60); spinach
(nearly 50); grapes (more than 30); bell peppers (nearly 50); potatoes
(more than 35); blueberries (more than 50); and lettuce (more than 50).
Cucumber, runner beans, and cabbage also feature in this category.
How to go about it, since you must eat
fruits and veggies daily? Nutritionists advise that we eat organic
fruits and vegetables. We are also advised to wash them thoroughly
before eating.
When doing your shopping, therefore,
those old women and men who bring their goods from nearby villages might
be the people to patronise. In places like the United Kingdom and
United States, they are called farmers’ market, while their produce is
called ‘organic.’
