Which one of the following choices is the closest in size to one serving of meat?
a. a deck of cards
b. a baseball
c. a coffee mug
d. an open palm

The answer is letter A.  

Individuals should consume meats that are only about the size of a deck of cards. This is the normal dietary recommendations to ensure a healthy life. Individuals who tend to consume above normal servings of protein might develop chronic diseases and complications in the body. High concentrations of protein within the internal system might cause some internal organs (e.g. liver and kidney) to perform poorly. The kidneys will lose the ability to filter waste products and the liver will have a hard time to produce hormones that are necessary for the breakdown of protein molecules in the body.
