There's an increasing amount of genetically enhanced "frankenfood" being sold these days as result of cloning and other non-organic methods that may not set well with you. You might also have allergies to certain kinds of foods. To find out where you stand it might be a good idea to get a food tolerance test.

Don't scoff at the idea of a food allergy. There are millions of people that have food allergies. Sometimes people have them since they were little, and other times they develop them when they get older. If you do not treat your food allergy, it can become very serious.

Actually, fatigue is a common symptom of a possible food allergy. You may not always break out when you eat a food you're allergic to - you may just feel tired all the time. Your body is trying to tell you that something is wrong. It's tapping into the energy in one part of the body to help the afflicted part - sort of like Scotty takes engine power to put up the shields on Star Trek.

Usually if this occurs you will want to eventually see a doctor about this problem. They will be glad to set up a time for you to come in. The appointment does not take all day and is something that could potentially save your life. They will perform a number of tests on you including a food intolerance test.

A list of foods that is best to be avoided, can be given by a doctor, with the results of the food intolerance test. The list of foods for most people is very short, and hence does not require any drastic change in their food habits. However, for some people it could require a change in lifestyle. In any case, it is better to know the results.

In the end, you may want to take a food intolerance test to make sure you can live life to its fullest potential. It is a short procedure, and it is definitely worth it to make sure you are not digging your grave. So if you think you have a problem, go to a doctor.
