Health Tip – May 18 – Folic Acid May Tone Down Allergy Symptoms
The higher your blood levels of folic acid, the less chance you may have of developing allergies or asthma. While that conclusion needs to be confirmed by further studies, researchers from Johns Hopkins have reported that folic acid may help regulate immune system responses to allergens (ragweed pollen, dust and other substances that set off sneezing, wheezing) and also reduce the symptoms of allergy and asthma.
The Hopkins team reviewed the medical records of more than 8,000 people ages two to 85, tracking the effect of levels of folate (the naturally occurring form of folic acid) on respiratory and allergy symptoms and on levels of IgE antibodies, the immune system proteins that rise in response to allergens. They found that individuals with higher blood levels of folate had fewer IgE antibodies, fewer reported allergies, less wheezing and a lower likelihood of asthma.
