A lot of energy is used in chewing. chewing gum can increase bodily energy expenditure by up to 15%, according to an experiment.

The University of Manchester's Adam van Casteren and his colleagues measured energy use in 21 people between the ages of 18 and 45 as they chewed gum.

The gum was tasteless and free of calories and odors. Van Casteren says that this way it doesn't cause as much damage to the bicyle. We wanted to measure just chewing or as close to chewing as possible.

The participants were asked to chew two types of gum, one soft and the other stiff, so that they could compare the effects of the gum on their energy expenditures.

A plastic dome was used to measure energy expenditure. The amount of carbon dioxide released and the amount of oxygen in the dome were measured. The information can be used to work out how much energy is being used.

The participants wore a plastic dome while they watched a film in order for the researchers to capture their energy expenditures.

The researchers found that chewing the soft gum increased energy expenditure by about 10 per cent while chewing the stiffer gum increased it by 15 per cent. It is interesting that a small change in the properties of the gum had a noticeable effect on energy expenditure.

He thinks the energy used to chew real food will be even bigger than it is now because many foods such as steak and nuts need a lot of effort to break down. He wants to know how much energy the nuts and seeds consume.

It is believed that the energy expenditure required to chew may explain why we have strong teeth. The meal is less efficient when energy is lost while chewing.

The increase is still only a small amount according to Dylan Thompson. He says that it will contribute less than 1% of total daily energy expenditure.

Thompson's study found that standing for 20 minutes increased energy expenditure by about 12 percent.
