Nutritive Additives

I. Introduction and definitions
 Food fortification or enrichment with vitamins,
minerals and other nutrients is not a new practice.
 Addition of Iodine to table salt to treat goiter
started by 1831 while addition of vitamin A to
margarine started by 1917.
 Many terms related to nutritive additives are
available, those include fortification, enrichment,
standardization, restoration, nutrification …………
etc.

II. Nutrient Minerals
 Minerals are defined as substances having specific
physiological activities, and their availability in
food is considered essential to maintain good
health.
 The daily human needs from some minerals is
considered relatively large and exceed 100 mg. An
example for this class of minerals is Ca, P, Mg, Na.
 Other minerals are being needed in small quantities
and less than 1 mg/day; these minerals are called trace
elements and include cupper, iodine, molybdenum,
selenium, chrome ….etc .

III. Vitamins
 Vitamins are organic substances which the
human body needs in very small quantities
and are essential for living cells.
 The human body which can not synthesize
vitamins in sufficient quantities should be
provided with them by food.
 It is well established that human body is in
need for 12 vitamins.

A. Causes behind encouraging of enrichment
1. The new trends towards lowering the calories
intake
2. The huge spread of snacking
3.Replacing of high nutritive value traditional food
with those of low nutritive value food
4. Reducing barriers in International food trade

genetic and seasonal factors

VI. Potential over-dosage of nutritive additives
It is well known that over-dosage of nutritive
additives such as vitamins, minerals and sometimes
amino acids are not desirable and may cause healthy
problems.
Overdoses of vitamins A and D proved to cause
toxicity;
Overdoses of some minerals may cause imbalance in
the absorption of some nutrients.
Regarding trace elements, overdosing causes toxicity
and as was mentioned in the selenium toxicity event.
