Education Phase 4 Malnutrition, food
fortification and supplementation
2
Malnutrition Meeting the bodys needs for energy
and nutrients is essential for good health.
Intakes of energy and/or nutrients below or in
excess of needs over time can affect health and
lead to health problems. Malnutrition is a term
which covers problems of under nutrition and over
nutrition.
3
  • Micronutrient deficiencies
  • Malnutrition includes deficiencies in
    micronutrients, which are nutrients needed in
    small amounts for many different essential
    functions in the body. Deficiencies in some
    micronutrients can lead to disease, for example
  • Vitamin D deficiency rickets (in children) and
    osteomalacia (in adults)
  • Vitamin B12 deficiency pernicious anaemia
  • Vitamin C deficiency scurvy
  • Iron iron deficiency anaemia
  • Iodine wide spectrum of iodine deficiency
    disorders (e.g. goiter, endemic congenital
    hypothyroidism).

What is fortification? Fortification involves
the addition of nutrients to foods irrespective
of whether or not the nutrients were originally
present in the food. The aim of fortification
is to help the population achieve the recommended
amounts of nutrients. Fortification is often
undertaken to address low intakes of a nutrient.
Dietary surveys can suggest which groups of the
population might benefit from having higher
intakes of some nutrients.
5
  • Restoration and substitution
  • Nutrients or food components may be added for a
    variety of reasons
  • Restoration this is where nutrients lost during
    food processing are replaced. For example, by law
    in the UK, iron, thiamine and niacin must be
    added to brown and white flour, as they are
    removed with the bran during the milling of wheat
    to make white and brown flour.
  • Substitution nutrients are sometimes added to
    produce a substitute product with similar
    nutritive value. For example, some soya based
    drinks sold as a substitute for cows milk may
    have calcium voluntarily added.

6
Why fortify foods? Adding nutrients to foods,
particularly staple foods such as cereals, milk
products, sugar, oil and salt, can increase
intakes among most of the population. In
countries where intakes of certain nutrients are
very low, fortification can help to reduce
nutrient deficiency diseases. For example, the
addition of iodine to salt to decrease iodine
deficiency disorders such as goiter. Fortificatio
n of some foods may also be seen as providing a
marketing advantage, especially where the
purchasers have some awareness of the benefits
of the nutrient being added. This may include
adding nutrients to products that would not
normally be a natural source, such as adding
omega-3 fatty acids to breads and fibre to
yogurts. The addition of a nutrient may also
offer some technical benefit (for example,
vitamin C is an antioxidant and can reduce the
rate of spoilage in some products), or a direct
health benefit for a subgroup of the population
(for example fortification of flour with folic
acid to prevent neural-tube defects in babies).

  • EU Legislation
  • The legislation regarding food fortification in
    the EU is Regulation (EC) No 1925/2006 on the
    addition of vitamins and mineral and of certain
    other substances to food. It applies only to the
    voluntary fortification of foods, not to foods
    that are subject to mandatory fortification, and
    specifies upper safety limits and minimum levels
    for each nutrient.
  • Vitamins and minerals may not be added to
  • unprocessed foods e.g. fruit, vegetables, meat,
    poultry and fish
  • beverages containing more than 1.2 by volume of
    alcohol.

EU Community Register The EU Community register
contains information regarding national
provisions on the mandatory addition of vitamins
and minerals to foods. The register can be
accessed from this page http//ec.europa.eu/food/
food/labellingnutrition/vitamins/index_en.htm

UK Flour fortification Nutrients can be lost
during the milling process (e.g. in the
production of white and brown flour), the amount
being dependent on the quantity of bran and germ
removed. However, the UK food industry is
required by law to restore nutrients lost through
milling. This regulation stipulates the amount
of iron, calcium, thiamine and niacin that must
be added to all white and brown flour, to restore
the nutrients lost in the milling process to
levels present in unrefined, wholemeal flours.
This ensures that white flour and brown flour
contain similar levels of these nutrients to
wholegrain flour (which contains the endosperm,
germ and bran). Flour fortification means that
products made with the fortified flour e.g.
bread, will also therefore be fortified.
10
Certain EU countries Margarine
fortification Margarines have the same amount of
total fat as butter, but with less saturated fat.
Margarine is defined by law and must contain a
minimum of 80, but less than 90 fat and a
maximum of 3 milk fat. It is mandatory to
fortify margarine with vitamin A at levels of
800-1000µg per 100g and vitamin D at 7.05-8.82µg
per 100g, under UK law. Belgium, Poland and
Sweden also have legislation requiring the
mandatory fortification of margarine with vitamin
A and D in various amounts.
11
Certain EU Countries - Salt fortification Since
the 1920s, some countries have iodized their salt
to help prevent against iodine deficiency
diseases. The World Health Organisation (WHO)
recommends universal salt iodization the
fortification with iodine of all salt used for
human and animal consumption as the main
strategy for eliminating iodine deficiency. EU
countries which require the mandatory
fortification of salt with iodine include
Austria, Denmark, Lithuania, Poland and Slovenia.

12
EU - Fortification of breakfast
cereals Breakfast cereals are fortified in many
countries across the EU, with micronutrients
including B vitamins, iron, calcium and vitamin
D. This can provide a valuable contribution to
the diet of breakfast cereal consumers.
13
Supplementation Food supplements are
concentrated sources of nutrients or other
substances with a nutritional or physiological
effect, with the purpose of supplementing the
normal diet. Food supplements can be in the form
of pills, tablets, capsules or liquids in
measured doses. Supplements may be taken in
order to correct nutritional deficiencies or
maintain an adequate intake of certain nutrients.
However, in some cases an excessive intake of
vitamins and minerals can be harmful to health.
Therefore maximum levels are necessary to ensure
their safe use in food supplements.
14
EU Legislation Supplementation The main EU
legislation is Directive 2002/46/EC related to
food supplements containing vitamins and
minerals. To ensure a high level of protection
for consumers and facilitate their choice, the
Directive ensures that products put on the market
must be safe and bear adequate and appropriate
labelling. The Directive sets out labelling
requirements and requires that EU-wide maximum
and minimum levels are set for each vitamin and
mineral added to supplements. More information
can be found http//ec.europa.eu/food/food/labell
ingnutrition/supplements/index_en.htm
15
Supplementation Different countries have
different supplementation policies. UK Infants
and dietary supplementation In the UK, the
Department of Health recommend that all children
from six months to five years old are given
supplements, in the form of vitamin drops, which
contain vitamins A, C and D. For growing
children, it is sometimes difficult for them to
get enough vitamin A and C, especially if their
diet is not varied. It is also difficult to get
enough vitamin D as there are few food sources
and the main source, sunlight, is limited, due to
the importance of keeping childrens skin safe in
the sun.

  • Denmark Pregnancy and dietary supplementation
  • The Danish Health and Medicines Authority
    recommend that pregnant women take the following
    supplements
  • 400 µg of folic acid a day from when trying to
    conceive, until week 12 of pregnancy.
  • 10 µg of vitamin D a day throughout pregnancy.
  • 40-50 mg of iron a day from week 10 of your
    pregnancy.
  • 500ml of milk and dairy produce is the best
    sources of calcium but if a pregnant woman does
    not eat or drink dairy products, the authority
    recommends a supplement of 500 mg of calcium a day
