Food additives are used to enhance flavors, prevent spoilage or change the colors of food products. There have been no definitive studies showing that they cause migraines, but many migraine sufferers report sensitivity to food additives and this link has been documented by various migraine associations. Although studies indicate general additive safety for use in food, some people may still find that they are sensitive to specific additives.
Monosodium Glutamate (MSG)
MSG is used as a flavor intensifier for other compounds in food. It is commonly found in soups, broths and restaurant food as well as being a component of yeast extract and hydrolyzed vegetable protein. It has been suggested that MSG may stimulate nerve cells to release certain neurochemicals that cause headache and migraine symptoms, which include pain and vasodilation in the head and neck.
Nitrites/Nitrates
Nitrates are not as widely used today, but nitrites continue to be added to cured and otherwise processed meats, such as hot dogs, bacon and luncheon meats. Nitrites serve to provide the aesthetic pink color in these products, add flavor and inhibit bacteria. In recent years, several studies have demonstrated that nitrites may intensify headaches in patients suffering from migraine.
Aspartame
Aspartame is a sweetener that has been approved for use and is generally considered safe. It is available on its own in powder or tablet form and is also used in many 'diet' food products. Despite its legal acceptance for use, many scientists have expressed caution for its use by those experiencing migraines.
Yellow Dye #5
Yellow dye #5, also known as tartrazine dye, gives foods a yellow color. Many colored foods contain tartrazine dye and some drugs are also colored with this additive. It is not directly known why tartrazine dye triggers headaches and migraines in some people but until more research is performed to establish or rule out a link, it is a food additive migraine sufferers should ingest with caution.
Sulfites
Sulfites are a class of chemicals that can keep cut fruits and vegetables looking fresh and are found in various alcoholic drinks, notably wines. Some people who suffer from migraines feel that their headaches are triggered by sulfite containing foods although no scientific studies have yet shown a direct link. Alcohol withdrawal is well documented to cause headaches and it may very well be withdrawal from the alcohol itself rather than sulfites that triggers a migraine headache.
Tyramine
Tyramine is an amino acid found naturally in aged cheeses, especially strong cheddars, and it is also found in red wine and other alcoholic drinks, and some processed meats. Studies on the tyramine-migraine link have thus far shown mixed results, which of course is of no relief for those suffering from migraines. Even with the lack of conclusive scientific evidence, anecdotal evidence still indicates a decrease in migraine headaches when dietary tyramine is reduced.
Some migraine patients show an elevated level of tyramine and this may be due to problems metabolizing the tyramine ingested from food.
Lots of Conflicting Information: What Can I Do?
Monitor what you eat and drink and if you get a headache, write down any food or drink you consumed prior to the onset of the headache. If you suspect a particular additive, try to obtain the same food item without the additive. For example, instead of meat deli slices on a sandwich, you might try bite-sized steak pieces in a wrap.
Generally, the more processed a food, the more likely it will contain food additives. Keep in mind that additives can be 'hidden' in various foods that you may not expect to contain the additive so be sure to read labels. If you see a pattern of migraines over time, you can either eliminate or reduce consumption of the food. Avoiding a suspected food trigger or group of food triggers entirely, however, is not always wise.
Complete elimination of certain foods can adversely affect other areas of your health. If you do eliminate a food, then be sure to substitute another healthy one and ensure that you eat regular meals, or you may find a migraine is triggered by low blood sugar.
There are a number of reasons for food manufacturers to add artificial and natural additives in food. For example, to lengthen shelf life, to make the food more appealing by enhancing color, texture and taste, to facilitate food preparation, or otherwise make food more marketable. An increasing number of additives are made synthetically, and some are from natural sources.
You may think many additives are used only in small amounts, and will do no harm, but it has been estimated that an average American consumes about 5 pounds of additives every year. When plain sugar is added, which is the most common used additive, the number rises to 135 pounds per year. This means that anyone whose diet includes a lot of processed food will consume a significant amount of additives and artificial ingredients. The numbers are rising.
Additives and artificial ingredients add very little or no nutritional value to the food product. Instead they pose a threat to your health. Some earlier approved additives have later been pulled off the market, or their use is allowed only if accompanied with warnings. Saccharin and Syclamate, which have been used as artificial sweeteners, are good examples. Some additives are used without warnings like Monosodium Glutamate and Aspartame, yet they have been known to cause health problems. Some reported disorders are head ache, diarrhea, confusion, memory loss, and seizures.
There are three main components in Aspartame; the amino acids Phenylalanine and Aspartic Acid, Methanol which is also known as Methyl Alcohol or as Wood Alcohol. It has been claimed that the amino acids in Aspartame are metabolized the same way as the natural amino acids in the food, but research suggests otherwise. Aspartame appears to cause a fast rise of these amino acids in the bloodstream. This will not happen when consuming natural dietary proteins.
No one disputes that Aspartame is not safe for people with PKU (Phenylketonuria). These people lack the enzyme required to convert Phenylalanine into Tyrosine, which is an amino acid. High concentrations of Phenylalanine can cause brain damage. It could also be beneficial to avoid food products containing Aspartame and other artificial ingredients for people who have other kind of disorders.
Methyl Alcohol is known to be toxic even in modest amounts. Disorders caused by toxic levels of Methanol include brain swelling, blindness, and inflammation of pancreas and the heart muscle. The cumulative effects of Aspartame are unknown.
The FDA states that the exposure to Methanol is not of ?sufficient quantity to be of toxicological concern?. Regardless of any claims by the FDA, significant number of people have reported bad reactions to Aspartame like head aches, mood swings, nausea, diarrhea, sleep disorders, memory loss, changes in vision, confusion, and even convulsions. Aspartame appears to be especially dangerous for children.
Needless to say, it is wise to avoid food with additives and artificial ingredients, and eat fruit and natural whole food. Those are free of artificial colorings, preservatives, and artificial sweeteners. Instead they are full of nutrients you need to stay healthy.
