Is Your Diet Making You Feel Bad?


Indigestion, headache, fatigue. Have you ever experienced these symptoms after eating a meal? An estimated 60 to 70 million Americans suffered from gastrointestinal ailments in 20101, according to the Department of Health and Human Services, and while that number bodes well for the manufacturers of antacids, it’s not so good for your body.

Overeating, eating rich foods, or poor food combinations can cause adverse physical reactions. But, in some cases, there may be another culprit at work: Food sensitivity. Food sensitivity is caused by an allergy or intolerance to a specific food or food product.

A food allergy is an abnormal immune response to a food. An allergic reaction can range from an irritated mouth to a rash to severe asthma attack. Allergic responses can occur with exposure to minuscule amounts of a specific substance.  Even a trace amount of peanut oil, for example, can prove life threatening to a child with this food allergy.  Allergic reactions occur within a few minutes to an hour after consuming the food in question. True food allergies are often genetic.  According to a study released in 2013, food allergies among children increased approximately 50% between 1997 and 2011 and now occur in about 1 in 13 children 2.

Many people confuse food allergy with food intolerance. Food intolerance is much more common than food allergy. According to the Centers for Disease Control and Prevention, approximately 70 percent of adults have some degree of lactose intolerance

Food intolerance occurs when the digestive system is unable to break down and metabolize a food product, and that food product acts as an irritant to the body. A person could be sensitive to the whole food or to a byproduct created during the digestion of said food. These reactions are also called hypersensitivity reactions. Symptoms include those of food allergies as well as migraines, joint pain, stomach bloating, swelling of the feet, and mood swings. Food-intolerance symptoms can occur within a few minutes to several days after consuming the food.

The top five most common foods or food products behind allergies or intolerances include: proteins found in eggs, wheat, dairy, soy, peanuts, shellfish or corn; milk lactase (an enzyme); salicylates (naturally occurring preservative) in herbs, fruits and vegetables; purines (organic chemical compound) in meats; and naturally occurring monosodium glutamate (MSG) found in tomatoes, peas and corn. In addition, food additives, such as preservatives, food coloring, artificial flavors and bleaching agents, can also cause adverse reactions

Scientists have discovered that the more often a person is exposed to a food, the higher the risk for developing an intolerance to it. But simply avoiding the food in question may be more difficult than you think. Some of the foods most commonly associated with sensitivities are “hidden” in other products. For example, milk proteins and sugars are added to luncheon meat, multivitamins, asthma inhalers and numerous prescription medications.
