Along with the development of biotechnology, there are more and more researches related to biofortification. Biotechnologists have already discovered how to strengthen the features of crop plants to enhance their nutritional value. In the 21st century, the advancement of nutritional health is one of the considerable issues because of the constantly rising and aging world population (Blancquaert et al., 2014). The meaning of fortification is to increase some essential nutrients in a food deliberately, such as vitamins and minerals (including trace elements), in order to improve the nutritional quality of food provision and to supply public health benefits at a minimum of health risks. While biofortification refers to the process of improving …show more content…
The aim is to make plant foods more nutritious while plants are growing up without adding nutrients. As a result, biofortification is a tremendous possibility for handling micronutrient deficiencies in the developing world (Global Farmer Network™, n.d.). Folate deficiency which is influencing billions of people in the world is a serious and underrated problem of micronutrient malnutrition. Policies are being adjusted to confront folate deficiency in many countries, mostly by using biofortification technology to fortify foods with folic acid (Blancquaert et al., 2014). There is another study that shows biofortification being a new option to rival the deficiencies of vitamin A, iron and zinc. Scientific evidence and predictive cost-benefit analyses demonstrate that biofortification is technically achievable without affecting agricultural productivity and vital in medical equipment for managing micronutrient deficiencies (Nestel et al., 2006). Thus it can be seen why biofortify food is …show more content…
There are 47% of pre-school children, 30% of menstruating women and 42% of young, pregnant women are suffering from iron deficiency. Vegetarians and vegans also have a opportunity of iron deficiency. Iron, which is a fundamental mineral, is a main element of red blood cells. If people suffer iron deficiency, the most ordinary consequence is anemia. The symptoms of anemia are usually weakness, tiredness, impaired brain functionand weakened immune system (Bjarnadotti, 2015). Zinc deficiency was first been discovered in 1961, being obvious to be a significant malnutrition problem in recent. Infants, children, adolescents, pregnant, lactating women and elderly are the groups at high risk of zinc deficiency. For young children and teenagers, they need lots of zinc during growth. For pregnant and lactating women, they demand more nutrition to nurture new born baby. A healthy human generally absorbs zinc around 107 µmol/day to 232 µmol/day. Zinc is widespread in cells and the character of it in human body can be divided into three broad categories: namely catalytic, structural and regulatory functions. The people who lack of zinc will affect their organ systems such as epidermal, gastrointestinal, central nervous, immune, skeletal, and reproductive systems (Roohani et al., 2013). In 1920, vitamin A deficiency was generally known between destitute people around the world
Vitamin B12 deficiency limits selenium methylation and excretion resulting in higher tissue selenium levels and subsequent toxicity. It occurs in people whose digestive systems do not adequately absorb the vitamin from the foods they eat. Vegetarians who eat eggs and milk products are the most at risk because, on average, they consume less than half the adult vitamin B12 Recommended Dietary Allowance (RDA) while strict vegans (who don't eat any animal products, including meat, eggs, or milk) are at an even greater risk. Vitamin B12 is important since it works with the vitamin folate to make the body’s genetic material and help keep levels of the amino acid homocysteine in check which helps to decrease heart disease risk. It is also essential in the production of red blood cells which carry oxygen through the blood to the body’s tissues. Life Extension gives offers some of selenium supplements. Babies who are born of parents with low selenium and vitamin B12 rich foods are at risk of anaemia.
Because the Ornish diet restricts participants to a strictly vegetarian meal plan, people who follow the diet often become deficient in beneficial nutrients such as vitamin B12, iron, and omega-3 fatty acids1. Vitamin B12 and iron are nutrients often found in animal products such as meat, while omega-3 fatty acids are most common fish – the foods present in a balanced diet, but absent in the Ornish diet. Deficiencies of these chemicals can often lead to conditions such as anemia, or prevent beneficial effects that are imparted by omega-3 fatty acids such as mood stabilization and improved cardiovascular health. Because the body needs iron to produce hemoglobin – a vital part in a red blood cell’s ability to transport oxygen to other cells, a lack of the substance would cause a large decrease in the effectiveness and number of red blood cells. In addition, due to vitamin B12’s regulation of blood cell production, a decreas...
..., non-heme iron will be the prime source of iron implicated in her diet, which has been discovered to be a less absorbing iron found in plant-based sources than in comparison to heme iron, which is predominantly found in animal products. In order to effectively enhance the absorption of non-heme iron, adequate intake of vitamin C needs to be initiated within her diet. Zinc and iron must not be consumed in excess of each other in order to prevent deficiencies of either due to their counteracting mechanisms; however, it is not a major problem in vegan diets due to its rare incidence. Although Jenny Brown does not initiate supplements in her diet, Jenny can still receive adequate nutritional benefits that are essential for her health by consuming a variety of plant-based sources and following the recommended requirements of nutritional intakes, according to her status.
Inadequate iron stores in the blood cause iron deficiency anemia. Iron is needed for the production of hemoglobin needed for red blood cells. Hemoglobin is important in the transport of oxygen to the body tissues. In the United States, 10-30% of the entire population suffers from iron deficiency anemia. Women are more likely to be anemic because of poor eating habits and blood loss during menstruation. Thus, many women enter pregnancy with reduced iron stores or some level of anemia. According to multiple studies on anemia and pregnancy o...
Since World War Two, the demand for convenient food, ethnic foods, and fresh fruits and vegetables has risen as a result of increases in income and the prevalence of dual-income families, together with the desire for food variety and healthy foods. The agriculture industry works and develops to meet these demands. Into recent times, societies share a growing concern regarding the environment, climate change, food safety, and animal welfare. Pertaining to agriculture, these concerns question issues such as soil and water conservation practices, use of pesticides and chemicals in crop production, growth promoters, and livestock treatment practices in animal agriculture. However, the industry’s scientists continue to work and research ways to balance the industry and bring environmental and economic

With the rapid growth of our global population pouring into the next millennium, we will witness an ever-growing hunger rate around the world. That is unless we call for a revolution on the global scale. The Green Revolution which already sprouted in the early part of the century only need to add a bit more momentum and we will see a bright future for the human race, a future without hunger and starvation ¡V hopefully.It is becoming increasingly difficult for the planet to support its overwhelming population. And since the amount of arable land available is becoming scarce, we must seek ways to dramatically improve crop yields of existing cropland.
According to scientists, genetically engineering crops contributes to their quality. Crops that have been genetically modified to have a particular trait can decrease the amount of herbicides needed for growing that crop. Additionally, genetically modified (GM) crops can help third world countries, where malnutrition is common. For example, to help diminish nutrient deficiencies in developing countries, “plans were underway to develop a golden rice that also has increased iron content”(Whitman 2). In addition, GM crops can be modified to be able to “withstand the environmental challenges of drought, disease, and insect infestation” (Swenson 1). Growing GM crops can also result in fruits and vegetables that stay fresh for a prolonged period of time and taste better.
The human body requires small amounts of nutrients in microgram or milligram quantities in our diet because it cannot synthesize the necessary amounts on its own. These nutrients are considered micronutrients. Micronutrients are a combination of water, vitamins, and minerals. Vitamins are organic compounds that do not provide energy, but are essential to the body in helping “aid in metabolism, as well as the growth, development and maintenance of body tissues” (Byrd-Bredbenner, Moe and Beshgetoor 402). Vitamins are broken down into two groups, water-soluble and fat-soluble. The water-soluble vitamins are the B-vitamins, and vitamin C. The fat-soluble vitamins are A, D, E, and K. Minerals are needed in even smaller amounts, however these inorganic substances are necessary for “cell metabolism, nerve impulse transmission and growth and development” (Byrd-Bredbenner, Moe and Beshgetoor 485). Minerals can be categorized into major or trace minerals. The major minerals include Sodium, Potassium, Chloride, Calcium, Phosphorus, Magnesium, and Sulfur. Trace minerals are Iron, Zinc, Copper, Manganese, Iodine, Selenium, Chromium, Fluoride, Molybdenum and Ultratrace minerals.

The global population in the year 2050 is expected to be nine billion and the agricultural demand is expected to double. With the current population already over seven billion people, there are hunger issues all around the world (“New” par. 1). How are we going to deal with food shortages in the future? With less land to work with, strains on the soils, and the lack of water, it is getting harder for the farmers of the world to support our growing population. These complications are making it harder for farmers to produce quality, affordable food. To help the crops grow better, farmers use fertilizers and chemical sprays to enhance growth and control the weeds. Farming in the United States is a relevant business because it supplies people with food, provides people with jobs maintaining the used equipment with the new equipment being much more expensive, and it provides research for more efficient ways on how to feed the world.
New opportunities and challenges of human health are presented by the application of biotechnology to food. Biotechnology helps improve the quality and nutrition of foods consumed by people,this helps their health. Foods produced through biotechnology has been around for more than 15 years but people are still debating about how safe the food is. Biotechnology still have to plays its role by increasing agricultural productivity,especially in light of climate change. I believe that biotechnology is still going to help better th nutritional value of food. It can also assist farmers to increase their productivity so that they can feed their families and many people across the globe. The whole world should be using the food biotechnology because it has the ability to change the world,it can be to end world hunger .
We must concern the importance of vitamin to stay healthy. The blood sugar level and the amount of insulin must be stable. Nevertheless, food intake according to the food pyramid does not guarantee good health. For example, large portion of vegetables and fruits should be included in our diet, butif they are not product of organic farming, the comestible might show sight effects due to the usage of artificial fertilizers for crop production. Thus, human health will be affected also even if they practice their food intake according to the food
This can not be done with the same ineffective tactics that were used in the past, so that’s why people are developing new ways to eradicate hunger. When the Second International Conference on Nutrition (ICN2) was held, they discussed the nutrition component and how important it is that it is not overlooked. By paying attention to nutrient-dense foods and recognizing the different entry points for improving nutrition, the ICN2 argues the world will be one step closer in achieving the Sustainable Development Goal. Some of the entry points they discussed include “the promotion of crop diversification…, strengthening local food production and processing, and exploring regulatory or voluntary instruments for promoting healthy diets” (goals 2). Promoting the nutrition aspect of the goal can help achieve it because nutrients are what keep people alive and
Plant nutrition is area of plant biology that is of the utmost importance for the proliferation of plants. Without proper nutrition, plants would simply cease to exist unless drastic alterations were made. There are certain elements that are required for the plant to grow and reproduce; these elements are known as essential elements. There are three requirements of an essential element: the element must be required for the completion of the plant’s life cycle, the element must not be replaceable by another element in whole, and finally the element must be direction involved in the metabolism of the plant. Chemical compounds that are involved in proper nutrition have been designated as nutrients, and further classified as macronutrients and micronutrients. Macronutrients are needed for growth, metabolism, and many other functions, but are designated as “macro” because they are required in larger amounts. Macronutrients include carbohydrates, proteins, and fat molecules. Micronutrients have a much wider function that depends on the exact micronutrient. Micronutrients are designated as so because they are needed in much smaller amounts when compared to macronutrients. Examples of micronutrients include vitamins and minerals.
