While studies have indicated that vitamin B12 can help in
reducing the risk of cancer, the same studies also warn of possible harmful
effects where the vitamins are consumed in excess. In a 2009 study on patients
in Norway, consumers of manufactured vitamin B12 supplements were found to have
a slightly higher cancer risk. The study involved 7,000 heart patients and
determined those who consumed more B12 supplements were at a higher risk
of suffering from heart disease and heart attacks.
When naturally consumed in food containing the vitamin B12,
the risk of over-dosage is lowered. The body is able to gauge its deficiency
level and absorb only what it needs at a time. This natural process is also
advantageous because the consumption process provides the body with the
opportunity to extract other rare vitamins and elements as needed by the body. Besides,
what one gets from fish is the vitamin B complex as a whole which contains a
wider range of vitamin B from B1 to B12. There are only limited quantities of
each of these vitamins, lowering the risk of over-dosage even when fish is
eaten very regularly.
Some of the species of fish in Kenya such as Nile Perch and
Tilapia contain healthy amounts of vitamin B12. The traces, as contained as
part of the vitamin B complex, are sufficient enough to provide the health
benefits associated with the element, while being limited enough to ensure
there is no risk of over-dosage. Good preparation of fish is also an important
element in ensuring that vitamins are preserved in the best way possible. At
LEFi, fish is handled and kept fresh from its fishing point in L.Victoria to
the time the customers order. The nutrients are preserved through effective
handling to the greatest extent possible.
