This process is repeated a large number of times (typically 1,000 or 10,000 times), and for each of these bootstrap samples we compute its mean (each of these are called bootstrap estimates). We now have a histogram of bootstrap means.
Most people are able to safely chew and swallow foods of many different textures. As we chew, food is broken down into small pieces. Saliva moistens and binds food pieces together in preparation for swallowing.A dry or sore mouth can cause problems with chewing and swallowing.
When you chew gum it produces an excess of useless saliva in your mouth. This makes your stomach think it's hungry, or it's getting food, because when you're hungry more saliva is produced in your mouth. So although it doesn't exactly run a health risk, it could make you more hungry.
