Allergy:
According the National Institutes of Health, an allergy is an exaggerated reaction - or immune response - to substances (often called allergens) that are generally not harmful. These substances can include pollens, grasses, ragweed, dust mites, and certain foods. Several symptoms accompany an allergic reaction, including:
-Stuffy, runny nose
-Sneezing
-Increased tearing
-Itching of the nose, mouth, eyes, throat, or skin
-Red eyes
-Difficutly breathing or wheezing
-Coughing
-Hives or rashes on skin
-Stomach cramps
-Vomiting
-Diarrhea or frequent urination
-Headache

The following steps may help reduce allergen contact:
-Covering pillows and mattress with plastic covers.
-Using an air purifier.
-Eating fewer foods - such as eggs, citrus fruits, bananas, chocolate, peanuts, and shellfish - that are likely to cause inflammation and allergic reactions. Food coloring, preservatives, caffeine, alcohol, tobacco, and sugar have also been shown to -increase allergy prevalence.
-Eating fresh fruits and vegetables, whole grains, nuts, and seeds.
-Drinking plenty of water and fresh juices.

Furthermore, research suggests that many natural compounds have the ability to reduce the occurrence of allergic symptoms. These approaches may offer an excellent alternative to conventional therapies whose chronic use is often accompanied by several side effects.

Anemia: Anemia is characterized by a deficiency in red blood cells or in the concentration of hemoglobin (iron-containing portions of red blood cells). These deficiencies are caused by either decreased production or increased destruction of red blood cells. Anemia is most common among women in their reproductive years (5.8 percent), infants (5.7 percent), and the elderly (12 percent). Because one of the major functions of red blood cells is to transport oxygen, a decrease in red blood cells decreases the amount of oxygen delivered to the body's tissues, which results in the symptoms of anemia.

Signs and Symptoms :

There is tremendous variability among individuals as to when the following symptoms of anemia develop.

-Tiredness
-Shortness of breath
-Paleness
-Lightheadedness


Food Allergy
As many as two out of five Americans believe that they have allergies to certain foods. In fact, fewer than 2 percent have true food allergies. A food allergy occurs when the body's immune system reacts to otherwise harmless proteins in certain foods. While most food allergies are mild, in some cases they can cause anaphylactic shock, a serious, sometimes life-threatening, reaction. Food allergies affect mostly young children. With the exception of peanut allergy, the majority of children outgrow their allergic sensitivities.

What Causes It?

The foods that most commonly cause allergic reactions are peanuts, tree nuts (walnuts, pecans, almonds), milk, eggs, soy, fish, shellfish, and wheat. In most cases, allergies occur when an individual who has a genetic sensitivity to certain allergens is exposed to the substance.

Eczema
Eczema, also called dermatitis, is a patch of itchy skin where blisters form, then dry and become crusty. There is no cure, but treatments can make you comfortable and help prevent outbreaks.
