Each year without fail anywhere between 250,000 to 500,000 children go blind from Vitamin A Deficiency (VAD), more than half of those die within twelve months. To visualize this number think of Seattle, now imagine half or all of its population going blind. With a few dollars’ worth of food or supplements enriched in vitamin A this problem can be mollified. But getting fresh foods and vitamins to those with the greatest need has proven an insurmountable problem. Food Aid, while indeed lifesaving, is costly and does not fix the underlying problems in poor societies. To be truly secure people must have food independence, which is to say they must be able to grow their own food supply and not rely on outside markets. In countries such as Vietnam, the Philippines, India and China the main food staple is rice. While rice is a valuable source of carbohydrates, once the rice is milled, and its outer layer shucked, it losses most of its nutritional value. Thirty years ago two German scientists, Ingo Potrykus and Peter Beyer set out to see if they could do something about making a better rice. What they came up with was genetically modified rice that was bright yellow because it was rich in β (beta)-carotene, and was called golden rice because of its sunny hue. But before the two scientists could pat themselves on the back for solving Vitamin A Deficiency, anti-GM (genetically modified) groups such as Greenpeace denounced the unnatural solution and swore that golden rice would never find its way to third world farmers. Twenty eight years and approximately 10,000,000 million deaths later golden rice has still not been able to escape the red tape and fear mongering of the First World. And while golden rice is not a cure all for world hunger,... ... middle of paper ... ...Rice to Combat Malnutrition Disorders of the Poor. Nutrition Reviews. Vol. 51. No. 6. Pp. S101-S104 June.

GMO food can create healthy, nutritious food in greater quantities for the less fortunate. For example, Hadiya is a toddler, born to poor African farmers. Her eyes are a milky white. Blinded from birth because of a cataract caused by vitamin A deficiency in her diet, she will never see her parents, and it is likely that she won’t survive past five years old. This is sadly the case for thousands of African and South-East Asian children, just because they have a vitamin deficiency in their diet. Vitamin A is supplied by
Rice belongs to the larger family of grasses, Graminae, and the genus Oryza. The genus Oryza has twenty wild species and two cultivated species – Oryza sativa and Oryza glaberrima. O. glaberrima is mainly cultivated in the West African region, whereas O. Sativa is found in Asia where it is a popular variety for cultivation. Globally, O. Sativa is cultivated in over 112 countries (Chang, 2000). The cultivation of rice was initiated in the Asian region, particularly in China, and later on became popular in nearby countries such as India and subsequently Sri Lanka (Chang, 2000). Rice has been an important food source since 2500 BC and is a staple food for approximately half of the world’s population (Chang, 2000). The varieties of rice possess different nutritional qualities, which are determined by factors such as genetics, environment, fertilizers, milling, storage conditions, thickness of anatomical layers, size and shape of the grains and their resistance breakage and abrasion (Houston, 1972; Luh et al 1991). The terms paddy grain or rough rice denotes freshly harvested rice. The rough rice consists of a hull and the caryopsis (Figure 1). Beneath the hull lies the bran, germ and endosperm (Juliano and Bechtel, 1985). Rice is broadly categorised in to two varieties: brown rice and white rice. Brown rice is produced by removing the hull. This technique preserves the nutritional qualities of the rice. Removal of the bran and most of the germ layer in further milling leads to an excessive loss of nutrients, as in the production of white rice (Fernando, 2011). Rice is processed by grinding further according to several milling grades to obtain differen...
There is only a short four step process that enables one to produce golden rice. The genes that give golden rice is its ability to make beta-carotene in its endosperm come from daffodils and a bacterium called Erwinia uredovora. These genes, along with promoters (segments of DNA that activate genes), are inserted into plasmids that occur inside a species of bacterium known as Agrobacterium tumefaciens. These agrobacteria are then added to a Petri dish containing rice embryos. As they "infect" the embryos, they also transfer the genes that encode the instructions for making beta-carotene. The transgenic rice plants must now be crossed with ...
At the Swiss Federal Institute of Technology in Zurich, scientists created golden rice by inserting three genes into a certain rice variety which will in turn produce a greater amount of beta-carotene. This rice has a sort of yellowish hue, which has given the rice its name, golden rice. The rice is still under research and testing before it will reach the markets, which is guessed to be around 2003. If this rice is found to be safe and effective it will be a tool in providing these rice dependent countries with the nutrients they need.
As the number of people who are starving increases each day, many leaders and organizations throughout the world are looking for a solution to this global crisis. According to John Robbins, the founder of Earth Save and co-founder/president of the Food Revolution Network, “Nearly a million children die every year because they are weakened by vitamin A deficiency and an additional 350,000 go blind. Golden rice … will be a godsend for the half of humanity…” (Robbins). Genetic engineering could be the fix for this issue. Genetic engineering would allow for rice to be produced in mass quantities for a less expensive price than regular rice. Moreover, if genetic engineering of beef cows were to be pursued, it would allow for more beef to be produced per cow; this would allow people who are hunger stricken to get a well-rounded diet. Although critics of genetically modified crops argue that this might not be the healthiest solution to ending world hunger, these crops have been approved as safe by the Food and Drug Administration. Also, these crops would be a great supplement for people who need food immediately and do not have the resources to go and find a healthier source of
Genetically engineered crops could spur economic growth in developing countries through a combination of eco-friendly practices such as organic farming with genetic modification to create, “a system that slashes pesticide use, insulates crops against floods and drought, and protects the livelihoods of poor farmers in the developing world” (Vance). In addition to providing a means of steady income for such farmers, these crops could be altered to exhibit qualities of environmental resilience to account for greater production of food- enough to feed the world. An example of such produce is flood- proof rice, developed by Pam Ronald and her team to compensate for the predicted increase in frequency and duration of flooding in Southeast Asia as global warming occurs (Vance). This flood- proof rice was created with consideration of accessibility to poor farmers, using marker-assisted breeding to perform the genetic transfer, a cost-friendly and money-saving method, and through Ronald and her team developing a rice crop able to survive two weeks underwater (Vance). As such research and projects continue, through hundreds of more teams such as Pam Ronald’s, a positive outlook emerges on the horizon in terms of supplying the global population’s nutritional needs without increasing
We live in a world that is constantly changing and advancing thanks to technological advancements, especially in the field of molecular genetics. Today, we are discovering and implementing new ways to overcome the ill-fated symptoms developed as a result from poor health or accidents. We are also making advancements in the field of agriculture thanks to molecular genetics. As we all know, food is an essential entity in our lives and is abundant as well as relatively easy to obtain here in the United States. However, as good as it may sound, this is not necessarily true for developing countries. Many people in developing countries receive very little food, if any, due to its scarcity. It is estimated that in Asia alone, close to 800 million people go to bed hungry every night due to food shortage. This problem can be alleviated by turning to the production of genetically modified organisms (a.k.a. GMOs).
For centuries, man has found ways to manipulate nature and to select crops for more desirable traits. If society were to stumble across a technology that would further advance these selections, it could quite possibly and significantly reduce the number of starving and malnourished people in the world while at the same time benefit the producers. “The UN Food and Agriculture Organization estimate that farmers will have to produce 70% more food by 2050 to meet the needs of the world's expected 9-billion-strong population. That amounts to one billion tons more wheat, rice and other cereals.” Less than one per cent of the American population is responsible for growing and harvesting all of the food for this country alone. The demand overseas for American produce varies depending upon the product, but overall exceeds the supply. On the forefront of this worldwide embittering battle to end world hunger and provide cost-effective medicine, society has stumbled across the answer known as biotechnology and genetically engineered organisms. In the end, we shall see that the benefits outweigh the negatives.
Secondly, rice is such an adaptive crop that it is not impossible to successfully grow it in different environments where crops could not have been grown successfully- from swampy valleys and deltas to hot, dry land above the floods and even in the mountain forests (Piper 1993:1).
Malnutrition is common in 3rd world countries where impoverished people rely on a single crop. Such as rice for their main staple of their diet. But rice does not contain a good amount of nutrients.
After learning and debating both sides of the golden rice debate, I oppose the use of golden rice in developing nations. In the golden rice debate a major point was brought up, golden rice can reduce childhood blindness caused by VAD. At first glance, this statistic seems like a major pro in the argument, but continued research showed that golden rice is very hard to digest, especially if that person does not have a
A method which can help solve this problem is the use of genetically modified rice or ‘golden rice’. Rice can be genetically modified to produce beta carotene in the grain which is a type of pro-vitamin A. This process consists of ‘copying the genes which govern a particular characteristic from one organism and transferring them to another’ (GM Crops & the Envrionment: Benefits & Risks, 2000, p. 3).Originally, in 2000 the genes inserted was a plant phytoene synthase which came from a daffodil and the Erwinia uredovora carotene desaturase however, in 2005 through further testing at Syngenta’s Jealott’s Hill International Research Centre in...
Famine and malnutrition is a problem that is plaguing almost everyone, everywhere. Almost every country is involved and is suffering. Some countries and nations ridden with famine would include Africa, the Middle East, South America, and Latin America. The causes of famine and malnutrition come from many varying sources. There isn’t one country that is the same as another. The root of the problem vary from natural disasters, poverty, lack of water, to corrupt governments.
Food insecurity and poor nutrition is an alarmingly large problem for low income families, especially in developing countries. Many strategies exist to fight this problem, although not many of these address all the factors contributing to it along with all the possible solutions to solve it. In many cases, multiple strategies must correlate and work together so that all the determinants of this issue are addressed and can fight food insecurity from different angles. This essay will discuss the significance of the problem, a range of possible strategies to solve the problem, and go into detail on a select few that will correlate and work together to solve different factors of food insecurity and poor nutrition.
Rice is a staple food in Filipino diet. Filipinos still choose rice despite new varieties of food choices. It is also good for the body for it has vitamins like E for replenishing the skin, B vitamins to support and increase the rate of metabolism, zinc for immune function as well as carbohydrates, which supply the body with energy. These health benefits are important for the daily activities of Filipinos. Moreover, rice has no cholesterol and it is low in calorie.
