Food biotechnology is a weapon of millenary improvement in the agri-food sector. Most of our foods have been improved using biotechnological tools, although many times we do not know it. The latest generation of this update are the so-called genetically modified foods that are subject to great social controversy, mainly in the European Union. At present, its use implies a lower environmental impact and a greater income for the farmer, for what most probably they will prevail. Still, it is not the only possibility of using biotechnology in the agri-food sector. In this sense, the use of genomics opens up exciting possibilities. The sequencing of genomes is allowed in the knowledge of the raw materials of foods. But in addition, genomics is studying the microorganisms present in the human body. Those that populate the digestive tract, the so-called gut microbiome, is very important for our diet. We are beginning to understand their role in health and disease. This opens possibilities of nutritional intervention with probiotics and prebiotics that largely mark the future of food and health. [ABSTRACT FROM AUTHOR]

this article makes a reflection about the appearance of transgenic foods in society. This food is obtained by using biotechnology; however, in markets there have not been acceptation of this, due different factors that impact economic, environmental and social aspects. Some about this topic has proven the possible inconvenient generated by the consumption and production of this type of food, because inflict damages that might be irreversible in the future. In this article opinions before how it might influence ethics and moral in the development of the society before advances that present science and technology today, starting from the relevance that the human being has and the development lived nowadays in several ambits in their environment are submitted.

This article reflects about the ethical issues generated in society by the production and use of transgenic or genetically modified food manufactured by biotechnology, such as: the commercial interests that guide this new technology, ecological risks, risks to human health, the possibility of introducing new plagues. Each country must regularize all aspects related to transgenic food in order to avoid risks and abuses by transnational companies and in order to protect vulnerable sectors of agriculture and livestock. Bioethical dialogue is proposed to balance both proponents, those who reject and those who support the production and use of genetically modified organisms for food, clarifying data with the help of science and promoting free information for an adequate environment for the possible development of this technology in the context of each country and community.

Senesence of cells is associated to special chromosome structures called telomers which have a very important role in replication and stabilization of chromosomes during cell division. Telomers size has been linked to pathological changes observed in cardiovascular diseases, obesity and cancer. Recently, the pioneer research discoverers of telomer function deserved the Nobel Prize of Medicine in 2009. There is a close relationship between telomers length, nutrition and the emergence of transgenic foods. This article reviews this conection and prompts some questions about the consequences in future time this kind of food may have on humans. [ABSTRACT FROM AUTHOR]

The knowledge, acceptance for the consumption and opinion about the labelled of foods derived from biotechnology for the people of Havana city were evaluated. A total of 600 persons integrated the analyzed sample. The applied survey was evaluated by means of the approach of experts, using the methodology Delphy. Results indicate that 93% of citizens answered to not know about the theme. In relation to the persons that responded affirmatively that know about these foods, 87% accepts their consumption and 92% agrees with its labelled. The educational level of citizens determined the knowledge that they believe that have in relations to this theme and their perception about these products. The age of the persons did not determine significant differences in analyzed aspects. [ABSTRACT FROM AUTHOR]
