Does it take 82hrs to digest red meat?

The digestion time for red meat can vary depending on the individual and the specific type of red meat consumed. However, the total digestion process typically takes several hours, not 82 hours.

For example, a study published in the journal "Physiology & Behavior" found that the average gastric emptying time (the time it takes for food to leave the stomach) for beef was about 2.5 hours. The overall digestion process, including the absorption of nutrients from the meat, can take anywhere from 24 to 72 hours.

It's important to note that the digestion time can be influenced by factors such as the amount of meat consumed, the cooking method, the individual's digestive health, and the presence of other foods in the meal.
