The saying goes that an apple a day keeps the doctor away but there seems to be more mundane benefits to eating this delicious fruit.
After finding that compounds in apples called polyphenols were able to suppress allergic rhinitis in mice, researchers conducted a study with thirty-three patients aged 15 to 65 years with moderate or severe persistent allergic rhinitis, who’d been suffering from symptoms for 3 years or longer.
Allergic rhinitis is inflammation of the inside of the nose caused by an allergen, such as pollen, dust, mould or certain animal danders. Once exposed to them, the sufferer experiences symptoms such as sneezing, itchiness and a blocked or runny nose.
The patients were grouped, some were treated without apple polyphenols, others with a low dose of apple polyphenols, or with a high dose of apple polyphenols. Changes in the clinical symptoms were examined.
Significant improvements were observed in sneezing attacks, nasal discharge and swelling, The highest percentage of patients who showed an improvement in symptoms were those treated with higher doses of the polyphenols.
They concluded that apple polyphenols are effective in alleviating symptoms of persistent allergic rhinitis. So an apple or more a day may really relieve symptoms of various allergic disorders.
The study does not include details of dosage so it is impossible to recommend the amount of apples one needs a day to achieve relief. However, if you are one of the many sufferers of allergies, it might be worth increasing daily intake of apples. After all, they are delicious.
