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 />
