An apple a day keeps the doctor away?  May be we should change it?


There has been a saying about apple. “An apple a day keeps doctor away.” It is not cent percent true in modern lifestyle. Slow eating of apple causes tooth decay and force you to the dentist.

The nursery rhyme that tells the importance of eating apple, “Apple a day keeps doctor away,” has become a question mark today. Recent researches state that eating apple affects the teeth and you will have to visit the dentist frequently.

How can apple cause tooth damage?

There is nothing wrong either in the rhyme or in the truth that apple is a nutritious fruit. Apple is, of course, a good addition to any meal. It contains anti-oxidants and other nutrients for building up strength and immunity. But the way you eat it affects the dental system. A research study was performed by Dr David Bartlett, head of prosthodontics at King’s College London Dental Institute. They studied in various angles about apple causing tooth decay. Their studies revealed that the trouble is with the way we eat the apple and not with apple. Daily Mail quoted the words of Dr. Bartlett saying, “Doctors quite rightly say that eating apples is good, but if you eat them slowly the high acidity levels can damage your teeth.”

Worse than carbonated drinks

The research team at King’s College London Dental Institute revealed that danger caused to teeth by eating apples regularly can be up to four times more damaging than carbonated soft drinks. The drinks which are said to be associated with dietary erosion and acidity do not cause as much damage to teeth as it is by eating apple.

Tooth decay

Teeth have 2mm surface enamel and dentine which is the main supporting structure of the tooth beneath the enamel. Research found that people who ate apples had 3.7 times more dentine damage, compared with the carbonated drink consumers. Some varieties of apple contain more sugar which contributes to raised acid levels in the mouth that cause tooth decay. Fruit juices which have acidity normally affect teeth enamel.

Four tips to prevent tooth decay

Dr Glenys Jones, nutritionist at the Medical Research Council’s Human Nutrition Research unit, says that tooth decay by eating fruits or drinking fruit juices can be prevented by following certain tips.

1) Apple can be eaten with milk or a piece of cheese. Since both of them contain calcium, acidity can be neutralised.

2) If you drinking water immediately after eating an apple, it will wash away harmful effects and protect teeth.

3) Drinking fruit juice with a straw is another easy method to protect teeth from direct contact.

4) Brushing the teeth before taking acidic fruits or foods will act as a barrier between acid and food. Brushing after eating is always good for teeth.
