• Transgenic Maize: In the case of maize the new genes are inserted into the genome of the plant. Thanks to these modifications it receives is much more resistant to insects, glyphosates and herbicides. The corn kernels that are produced thanks to the genetic transformation is characterized by being brighter and having an orange color. �
• • Transgenic meat: This type of meat has been made for more than 20 years, when the animals( pigs, poultry, fish and cows) began to be modified. The modifications aim to increase the size and weight of the animals, as well as to accelerate their growth. �
• • Transgenic wheat: This wheat is much more resistant to droughts, insecticides and insects. However, it is worth noting that there are currently more cases of people who are intolerant to wheat and celiac, so it is believed that there is a direct relationship with the genetic modifications that have been made on wheat. �
• • Transgenic potatoes: In the case of potatoes the starch enzymes are invalidated by the introduction of an antagonistic copy of the gene that abolishes it. To be able to produce this type of potatoes it is necessary to generate the necessary conditions, since in fact it is quite complex, so much that at the moment one can not find this type of potatoes in the market. �
• • Transgenic tomatoes: The main difference between transgenic tomatoes and common tomatoes is that the time in which they are broken down is much longer. To achieve this, one of its enzymes has to be genetically inhibited by its opposite gene. For this it has to be introduced into the tomato genome. At the moment this type of tomatoes tries to be reinserted in the market, since previously they had been retired by certain difficulties the moment to commercialize them. �
• Transgenic rice: In order to be able to genetically modify rice, you must introduce three new genes, two from daffodils and one from a bacterium. The result is rice with higher vitamin A content. �
• Transgenic coffee: Generally, coffee is modified for the sole purpose of increasing production, but is also usually modified for increased resistance to insects, to decrease caffeine levels and to improve its aroma. �
• Transgenic grapes: Mainly the objective with which the grapes are modified is to increase their resistance and to eliminate the seeds they have�

How many types of transgenic foods are there?
We can consider the following groups of transgenic foods:
1. Substances used in animal treatments with the aim of improving production: The best example that we can mention about this type of transgenics are the bovine growth hormones that is used to increase milk production. This hormone is allowed in the United States, but not in the European Union.
2. Substances used in the food industry, obtained from microorganisms by recombinant DNA techniques: The best example we can mention in this case is recombinant chymosin( rennet), which is used in the
