We're often asked so what do you consider "a serving"?
Well, for dairy products - it's generally 1 cup and for vegetables a serving is usually 1/2 cup raw or cooked vegetables. Fruit is also about 1/2 cup or 3/4 cup for fruit juice.
Meat servings are considered to be 3 oz of cooked meat. Beans is 3/4 cup while grains are 1 slice of bread, 1/2 cup pasta or 1 cup dry cereal.
Generally we tend to consume bigger portions than one serving. However, if you're trying to eat a healthier diet, consider first and foremost - watching those portion sizes!
