A Study on Genetically Engineered Foods: Need, Benefits, Risk, and Current Knowledge

Abstract

Food requirements have always been a top priority, and with the exponential growth of the human population, there is an increasing need for large quantities of food. Traditional cultivation methods are not able to meet the current demand for food products. One significant challenge is the shortened shelf-life of naturally occurring food items, which directly contributes to food scarcity. Contaminating substances such as weeds and pests play a crucial role in this issue. In response, researchers have introduced genetically engineered (GE) food as a potential solution. These food products are typically created by adding or replacing genes in the DNA of naturally occurring foods. GE foods offer various advantages, including increased quality and quantity of food production, adaptability to various climatic conditions, modification of vitamin and mineral levels, and prolonged shelf life. They address the major concerns of global food scarcity and food security. However, the techniques used in the production of GE foods may not be universally acceptable due to the genetic alteration of animal genes into plants or vice versa. Additionally, their unique nature necessitates further long-term studies. This study delves into the procedures and growth stages of DNA sequencing, covering the benefits, risks, industrial relevance, current knowledge, and future challenges of GE foods. GE foods have the potential to extend the shelf life of food items, alleviate food shortages, and fulfill the current nutritional food demand.
