Onion, as
a common vegetable, is often seen in western dishes. Many people like it
because of its spicy taste. But others think that the strong taste is not
pleasant. Experts suggest that whether you like it or not, you should eat some
onion because it is useful in health care.

First of
all, it can prevent cardiovascular diseases. It restrains the rise of
cholesterol in blood. A doctor from HarvardUniversity points out
that if people eat half an onion or a same amount of its juice, the content of
high density lipoprotein would increase by about 30%. Moreover, he also finds
that if heart disease patients insist on eating onion regularly, they would
have lower risks of the condensation of blood cells. So he suggests people to
eat high fat food with it to prevent the slow blood circulation.

Secondly,
it is used in curing diabetes. A long time ago, people had used it to cure and prevent
diabetes. Recent medical studies have shown that it does reduce the content of
blood sugar no matter it is cooked or raw. Scientists say a compound, which is
similar to butyl amine, would stimulate the insulin release and normalize the
function of pancreases.

Thirdly,
it can fight against asthma. Scientists have extracted at least three kinds of natural
chemicals that can be used to cure asthma. These chemicals can restrain the
activity of histamine, which is considered to be the cause of asthma. A German study
tells us that it can reduce the risk of asthma by nearly 50%.

Fourthly,
the vegetable is a useful medicine that is widely used to prevent osteoporosis. The authoritative magazine,
Nature, has pointed out that onion is the most powerful vegetable to prevent
the sclerotin from running off. Scientists
tested the mice which had been eating a kilogram of onions every day for a
month to find that the weight of their bones increased by 13.5% to 18%. Another
experiment has indicated that the effect of this vegetable on protecting bones
can be seen as soon as twelve hours. Therefore, doctors suggest people to eat
200 grams to 300 grams a day to prevent osteoporosis. They hold the view that
the efficiency of onion is better than that of calcitonin.

In addition
to the above functions, onion can help with many other diseases. For example,
it is suggested for people to put minced onion beside the pillow if they have
difficulty in going to sleep. It is because certain substances in it can calm
the nerves. And when people have a cold, they can drink some miso soup with it.
It is said that such soup would quickly bring down a fever and cure the cough.
