There might be something wrong with your inner tube, and it could be making you sick and fat.

You may not even realize you have a problem ... but if you have health concerns of any kind or you are overweight, your inner tube could be the root cause.

Of course, I'm not talking about a beach toy. I mean the inner tube of life -- your digestive system!

You could blame weeds, trees, and grasses if you start itching, sneezing, coughing, and wheezing this fall. But the usual suspects aren't the only triggers. A host of household items -- candles, chemicals, stuffed animals, and spices -- may be the real culprits.
From blue jeans buttons to limes to teddybears, allergy triggers come in many ways, shapes and forms.

 Along with milk, eggs, soy, wheat, tree nuts, and shellfish, peanuts are among the most common foods that cause allergies.

Learning how to recognize an allergic reaction will help you get your child the medical care needed if a reaction occurs. If your child has already been diagnosed with a food allergy, it's important to know:

Wheat and wheat related products are hidden in many foods. Use this list as a guide to a healthful wheat-free diet...

Shellfish allergies are the most common allergy among adults in America, and they are more likely than most other allergies to manifest for the first time in adults. Shellfish allergies are allergies to two classes of foods: mollusks (which include clams, mussels, and oysters) and crustaceans (which include shrimp, lobster, and crabs). Although these two groups are fairly distant biological relatives, there is a high rate of allergic cross-reactivity between the two. So, many people who are allergic to any shellfish are advised to avoid all shellfish. Shrimp is the considered the most allergenic.

Peanuts are a common food allergen and can be hidden in many foods. Learn more about what foods and products to avoid.

People generally follow an egg-free diet for one of two reasons: either they wish to maintain a vegan (pure vegetarian) diet, or they are allergic to eggs. Most people who are allergic to eggs are allergic to egg protein and usually react to the proteins in the egg white. However, because it is impossible to completely avoid cross-contamination between yolk and white, people who are allergic to eggs need to avoid eggs completely. The most allergenic proteins in egg white are ovalbumin, ovomucoid, ovotransferrin, and lysozyme. Lysozyme is an unlabeled additive used in cheese preparation. Egg yolk contains three proteins (apovitellenins I & VI and phosvitin) that are also allergenic.

A dairy-free diet contains no milk, cheese, butter, cream cheese, cottage cheese, sour cream, ice cream, whey, casein, or foods that contain any of these ingredients.
