What does the Stephan curve show?
The curve on a graph, first described by Robert Stephan in 1943, showing the fall in pH below the critical level of pH 5.5, at which demineralization of enamel occurs following the intake of fermentable carbohydrates, acidic liquids, or sugar in the presence of acidogenic bacteria.
How is Stephan curve measured?
It uses the pH scale; pH is simply a measure of how acidic an environment is . 7 is the netural point, anything underneath that, is acidic and anything above it, is alkali (or basic) The further away from neutral you get the stronger the acid or alkali environment.
What is the vipeholm study?
A classical study undertaken between 1945 and 1953 in the Vipeholm Hospital, Sweden, to investigate the relationship between caries and the ingestion of sugar. The effect of different levels of carbohydrate intake on caries activity in 436 individuals observed for five years.
Why should sugary or acidic foods or drinks be avoided within 1 hour before a patient’s bed time?
Every time you eat or drink anything sugary, your teeth are under acid attack for up to one hour. This is because the sugar will react with the bacteria in plaque (the sticky coating on your teeth) and produce harmful acids.
What does science say about snacking after eating?
Although some dieters snack to boost their metabolic rates, research suggests these efforts are in vain. Studies that examine data for up to 48 hours after eating find that the jump in metabolic rate or the thermic effect of food is not dependent on meal frequency.
Is it true that snacking can help with hunger?
Their hunger levels and total calorie intakes didn’t change compared with the days on which they ate no snacks, indicating that the snacks had a neutral effect ( 10 ). However, studies have also shown that snacking can help reduce hunger ( 11, 12, 13 ).
How does snacking affect your metabolism and appetite?
However, most studies show that eating frequency has little or no effect on metabolism. Studies on snacking’s effects on appetite and weight have provided mixed results. How snacking affects appetite and food intake isn’t universally agreed upon.
Why do we have conflicting data on snacking?
Conflicting data may be the result of many factors, such as the way researchers defined a snack or eating occasion, whether or not caloric beverages were included in the analyses and underreporting of food, beverage and calorie intake, which can make dietary assessment tools invalid.
