It is food allergies that it is; but these bio tech corporations doesn't want people to know that their products is capable of having allergens. The only reason why that they doesn't want that secret to come out, it is because if someone is allergic to their products which that means that they will have to labeled their products and which they doesn't want anyone to know that our foods has been tampered with by splicing the DNA of one species with another specie. Like they had out on the market a few years ago that Flavor savor tomato. They had taken it off the market, but the reason why, they doesn't want anyone to know. But the tomato was combined with a gene of a fish to make it to be able to be tolerant to the freezing weather; but those that are allergic to fish will not be able to know that they are eating something that has fish in it and they will have a allergic reaction to this tomato that they had thought that it was safe to eat. Eventhough that it is a very small amount of fish DNA in it, but it is the antibiotic resistance gene that they put into their crops that lowers the plant's defense so that the plants have to accept the alien genes. And so if someone that is allergic to fish, that their immune system will not be able to defend them from the allergic reaction of the fish DNA that is in the tomatoes and so they will surely die.
Trust me if you really stay away from these products that you will see the differences in your thinking pattern and so on; as if you were drunk before feeling into a sober feeling. The mind will not be foggy no more and you will be a lot energetic, able to leap over high grasses in a single bound. Make you wonder why people has been doing a lot of strange things that they normally wouldn't had done.
