If you have a number of friends who are trying to lose weight, you might not have to discuss the topic for long before one friend suggests consuming jalapeno peppers to boost metabolism. Don't rush out to the supermarket and load your cart with this fiery, green pepper, however. Spicy foods can contribute to slightly quicker metabolism, but this minor benefit can come at a cost.

Spice Up Your Life
Spicy foods such as jalapeno peppers don't elevate your metabolism to quite the same degree that some people believe. According to a 2006 article in "The New York Times," spicy food can raise your metabolism for a short duration, but only by 8 percent. You don't need to use jalapeno peppers, which can be unpalatable for some people and safe to use only in moderate amounts, for spicing up your meals. ABC News reports that spices such as cinnamon, oregano and paprika can affect your metabolism too. Be wary of too much spice; consuming foods too heavy in spices can lead to issues such as heartburn and stomach ulcers.
