The most accurate way to monitor portion sizes is to measure out food with a scale and measuring cup. However, this is not realistic at many eating occasions. Your patients or clients can use this handy Serving Size Wallet card from NHLBI (http://hin.nhlbi.nih.gov/portion/servingcard7.pdf) to help them estimate the right amount to eat. And they can take the NHLBI Visual Reality quiz (http://nhlbisupport.com/chd1/visualreality/visualreality.htm) to test their skills at estimating serving sizes.
