One thing that has always confused me and sometimes even misled me about eating healthy is portion sizes. Sure, I know that fruit and vegetables are good for me but how much is the right amount? Similarly, I know to choose whole wheat grains like pasta and lean meats, but again, what is the right amount? Too much of any one type of food, no matter how healthy, is not good. This is where portion sizes come into play.
Sure you can buy a kitchen scale and weigh all your food, but these days people struggle enough to find the time to prepare healthy meals, let alone weigh their food! But there is a much easier way to estimate portion sizes without driving yourself crazy and it is in your hand.
