The last decade has brought about
tremendous changes in our thinking about the relationship of diet
and dental health. If you haven't heard the latest thoughts on
diet yet, you might be in for a surprise.
You Are What You Eat, But....
Except for the beneficial micronutrient
fluoride, nutrients in the food you eat probably have little effect
on whether cavities form in your mouth. Good nutrition certainly
contributes to overall good health but cannot ensure that your
children will develop strong, disease resistant teeth. Many factors
influence whether your children will develop cavities, and diet
doesn't matter too much if you pay attention to important steps
such as practicing routine oral hygiene, getting enough fluoride
daily, and having your dentist apply a protective sealant to the
back teeth.
Foods and Tooth
Decay
Let's get one thing straight:
foods alone do not cause cavities. Many of the foods we eat- including
some of the 'valuable' foods from the standpoint of human nutrition
- provide nourishment for oral bacteria. They, in turn, secrete
acids that can erode enamel and lead to cavities.
We feed the bacteria in our
mouth, every time we eat carbohydrates.
These come in
two types: sugars (simple carbohydrates) and cooked starches (complex
carbohydrates). Once in the mouth, cooked starches (like bread,
biscuits, chapattis, nan, etc.) start to be broken down into their
component sugars, by an enzyme in saliva. To the bacteria in your
mouth, sugar is sugar, no matter what "package" it comes
in.
Sweet treats such
as cakes, cookies and candies etc, are not measurably worse for
your teeth than a hearty meal of rice, dal, chapatti, bhaji, fruit
and a glass of lassi!
Refined sugar,
sucrose is what people think of as sugar. But other foods contain
"sugars" too. Dairy products contain a form of sugar called
'lactose', fruits contain 'fructose', cooked starches, such as chapatti
and rice are broken down in the mouth into other sugars, namely,
glucose and maltose.
