The body mass index is a weights in kilograms divided by the square of height in meters
When preparing food, it is especially important to keep the temperature out of the danger zone because bacteria can grow rapidly in this temperature range.
Bacteria grow at very high speeds in the range of the danger zone, which is the range of temperatures between 40° F and 140° F. Leaving food out at room temperature for a long time (more than 1-2 hours) can lead to some bacteria to grow to levels which are dangerous.
Hope this helps:)
