I suffer from it every year. Please tell me if there are any foods that
are good for easing hay fever.
Hay fever is an allergy that is caused by plants’ pollen. At certain time
of the year when pollen is dispersed, people suffer from sneezing, blocked
itchy eyes, watery eyes and a sour throat etc. caused by the specific pollen
acting as an allergen. These allergic symptoms are difficult to prevent
by controlling what you eat, but it is possible to ease the symptoms. It
is said that the active oxygen aggravates allergic symptoms, so hay fever
suffers should be encouraged to eat food that have an antioxidative effect.
It is also said that too much protein and fat in the diet could be a cause
of the allergy. Fast foods, ready made foods, strong spices, alcohol and
cigarettes should be avoided because they could aggravate the symptoms.
Hay fever is an allergy such as atopic dermatitis and asthma that have
increased in recent years. The allergic person develops a protein called
an antibody. When it comes in contact with an allergen, pollen in this
case, the body releases various chemicals such as histamine which causes
swelling and itching.
[ What is hay fever ? ]
1. The allergen - pollen is inhaled.
2. The antibody to the allergen is made inside the body.
3. The antibody sticks to the gemastete cell on the surface of the mucous
of the nose.
4. When the allergen enters the body, it starts “An allergen antibody reaction”
5. As a result, a chemical such as histamine is released from the gemastete
6. The chemical such as histamine acts on the nerves and the blood vessels
causes hay fever symptoms such as sneezing and itchy eyes.
The Japan’s forestry plan is said to be one of the causes. Many Cryptomerias
have been planted in recent years. Another could be that our immune system
is not as effective as before due to the stressful nature of modern living.
Having understood the causes of recent increases in hay fever, it is important
to improve our general health which in turn improves our anti-oxidation
power and our immunity. The symptoms of hay fever are eased by taking the
anti-allergy drugs commencing about two weeks before the season starts
but they can have serious side effects. The followings are recommended.
1. Eat foods that help the immune system and minimize allergic problems.
2. Avoid additives and too much animal proteins and fat.
3. Eat plenty of vegetables and yoghurt that contains lactic acid bacterium.
Vitamins, minerals and polyphenols are understood to be effective. Kakishibu contains a lot of polyphenols, which is available as a supplement.
An anti-allergic effect is recognized in flavonoid that is a kind of polyphenol
found in persimmon leaf. It is rich in vitamin C therefore it is also good
for the skin. It is also recommended for a block nose.
Ten-Cha is a sweetened tea from the southern part of China. The polyphenols
that are found in Ten-Cha are effective for allergy of the nose such as
hay fever and also available as sweets etc.
■ Perilla seeds
and Perilla leaf
They contain a lot of anti-oxidation materials. Leaves can be eaten as
they are. The oil from Egoma that is the same family as Perilla also contains
a lot of anti-oxidation materials.

“Tea that cures all diseases”. It contains Flavonoid that has an anti-oxidation
