Vitamin B2 - Riboflavin Benefits, Deficiency and Sources
|
|
Riboflavin (Vitamin B2) is a member of the B-group vitamins. It has a
fundamental role in cellular oxidation. It is a co-factor in a number
of enzymes involved with energy metabolism.
Sources: Its richest natural sources are milk, eggs, liver, kidney and
green leafy vegetables. Meat and fish contain small amounts. Cereals
(whether whole or milled) and pulses are relatively poor sources but
because of the bulk in which they are consumed, the contribute much of
the riboflavin to Indian diets. Germination increases the riboflavin
content of pulses and cereals.There are no real body stores of
riboflavin. Daily requirement is 0.6 per 1000 kcal of energy intake.
Deficiency: Deficiency of riboflavin or ariboflavinonis is widespread
in India particularly in populations where rice is the staple. The most
common lesion associated with riboflavin deficiency is angular
stomatitis, which occurs frequently is malnourished children and its
prevalence is used as an index of the state of nutrition of groups of
children.
Studies conducted at National Institute of Nutrition in India showed
that sub clinical riboflavin deficiency (as judged by the erythrocyte
glutathione reductase activation test) was present in over 80 percent
of low-income group children and adults. Hypo-riboflavin sis, even when
severe, seldom incapacitates the individual, but it may have subtle
functional effects such as impaired neuromotor function, wound healing
and par haps increased susceptibility to cataract. Riboflavin
deficiency almost always occurs in association with deficiencies of
other B-complex vitamins such as pyridoxine; it is usually a part of a
multiple deficiency syndrome.
