poor <strong>and</strong> hungry in the Global South <strong>and</strong> focus on<br />
one or two nutrients, such as Vitamin A or iron.<br />
Even if we assume that GM can produce more<br />
crops with high levels of one or two nutrients,<br />
some important topics need to be addressed before<br />
concluding that biofortifying crops by whatever<br />
means is a sensible approach to malnutrition:<br />
Malnourished people are hungry not because of<br />
a lack of biofortified crops, but because they lack<br />
money to buy food <strong>and</strong>, increasingly, access to l<strong>and</strong><br />
on which to grow it. This type of poverty is often<br />
due to political conflicts in the country. Another<br />
cause is ill-advised “development” programmes that,<br />
in return for foreign loans <strong>and</strong> investment, have<br />
forced countries to convert farml<strong>and</strong> from growing<br />
food for people to eat into growing cash crops for<br />
export. These are political <strong>and</strong> economic problems<br />
that cannot be solved by offering a biofortified crop,<br />
for which the grower will need to be paid. People<br />
who have no money to buy basic food will certainly<br />
be unable to buy a biofortified food that has taken<br />
millions in investment funds to develop.<br />
Malnourished people are not usually deficient<br />
in just one or two nutrients, but in many. Focusing<br />
on a crop that can deliver one or two nutrients is<br />
unhelpful because a balance of nutrients is needed<br />
for proper absorption. For example, in order to<br />
Conclusion to Section 3<br />
Contrary to frequent claims that there is no<br />
evidence of dangers to health from GM foods <strong>and</strong><br />
crops, peer-reviewed studies have found harmful<br />
effects on the health of laboratory <strong>and</strong> livestock<br />
animals fed <strong>GMO</strong>s. Effects include toxic <strong>and</strong><br />
allergenic effects <strong>and</strong> altered nutritional value.<br />
Most animal feeding studies on <strong>GMO</strong>s have<br />
only been medium-term in length (30–90 days).<br />
While GM proponents claim that the observed<br />
harmful effects on health are not “biologically<br />
relevant” or “adverse”, such claims are scientifically<br />
unjustifiable; these terms have not even been<br />
properly defined.<br />
What is needed are long-term <strong>and</strong> multigenerational<br />
studies on <strong>GMO</strong>s to see if the changes<br />
found in medium-term studies, which are suggestive<br />
of harmful health effects, will develop into serious<br />
absorb vitamin A, people need to have enough<br />
fat in their diet. This problem would need to be<br />
addressed before they could benefit from vitamin<br />
A-enriched food.<br />
Manipulating nutrients in food is controversial<br />
because it can be viewed as medicating food.<br />
Dosage is difficult to control <strong>and</strong> certain nutrients<br />
may be needed by one person, yet be excessive<br />
<strong>and</strong> potentially dangerous for the next. Also,<br />
nutritional theory is a fast-moving discipline, with<br />
today’s desirable nutrient becoming tomorrow’s<br />
undesirable contaminant. 138<br />
3.9.4. Non-GM biofortified crops are<br />
already available<br />
If we assume that biofortified foods are a desirable<br />
approach to malnutrition, plenty of non-GM crop<br />
varieties are available now that do not present the<br />
risks <strong>and</strong> uncertainties of genetic engineering (see<br />
Section 7).<br />
In addition, there are ways of adding<br />
nutrients to people’s diets that do not involve<br />
the considerable expense of crop breeding. These<br />
include a rice fortified with iron <strong>and</strong> vitamins,<br />
which has been reported in a preliminary study to<br />
have caused dramatic falls in anaemia <strong>and</strong> vitamin<br />
B1 deficiency in children. 139<br />
disease, premature death, or reproductive or<br />
developmental effects. Today, such studies are not<br />
required by regulators anywhere in the world.<br />
Moreover, the system for assessing the<br />
allergenic potential of GM foods in place in the EU<br />
today – although it is probably the most rigorous<br />
of any assessment system anywhere in the world<br />
– is inadequate <strong>and</strong> unlikely to identify new<br />
allergens.<br />
While GM proponents claim that GM can<br />
provide nutritionally enhanced (biofortified)<br />
foods, no such GM foods are available on the<br />
market.<br />
The most widely publicised example of a GM<br />
nutritionally enhanced food, Golden Rice, has<br />
used up millions of dollars’ worth of research <strong>and</strong><br />
development money. Yet it has not undergone<br />
