It causes cavities.
Yes, sugar has the ability to kill bacteria by drawing water out of their cells through a process called osmosis, which can cause the bacteria to die.
Any fruit could cause gas, since they all contain types of sugar. If you get too much sugar in your diet, the excess sugar can pass, undigested, to your large intestine, where bacteria can turn it into flatulence.
They can both prevent the growth of bacteria that cause food to spoil.
Only certain bacteria can grow on sugar (sucrose). In order for a bacteria to be able to grow on sugar a certain level of moisture must be present along with the ability to absorb sugar as a food/energy source.
Anything with sugar can cause caries (decay). Sugar combines with bacteria in your mouth and saliva and becomes acidic. It causes enamel loss and decay. Sugar is the leading cause of tooth decay. In addition, the carbonation in such beverages can wear away tooth enamel.
The bacteria yeast converts sugar into alcohol.
Sugar and starch.
Yes, bacteria often prefer sugar as a food source because it provides them with energy for growth and reproduction.
bacteria is the cause of tooth decay when you eat or drink sugary food or drinks ,the bacteria metabolise it and this metabolisation produce acids which make demineralisation (removal of minerals) of the tooth ,and bacteria then get deeper and repeat this process until reach the pulp
the concentration of sugar in the bacteria is low whereas that of the outside, where the sugar is, is high. to make the concentration balanced, water molecules have to leave the cells of the bacteria therefore causing the bacteria to shrink and eventually die. (sorry if the answer is too long) this process is called "hypertonic"
Mainly bacteria. When you eat the food gets stuck on your teeth. The food turns to sugar eventually and the bacteria eat the sugar and your tooth enamel also in the process. That is why eating lots of sweets which are high in sugar is worst than eating normal food because sweets are usually loaded with sugar. Solution to cavities? Always brush right after you eat so the food doesn't have time to turn to the sugar that the bacteria want to eat. Also be sure to floss. The food stuck betwen your teeth won't come out with just brushing. Flossing is critical to not having cavities. So is genetics. Some people are more susceptible to cavities than others. I can't tell you why but I have met people who have never had a cavity in their life while most everyone I know has has them. It's kinda weird to see someone open their mouth and their is no silver fillings, nothing but white.
