I found this is the Better Homes & Gardes site. Thought some of you would be interested.

Serving Sizes

What counts as a serving?
Bread, Cereal, Rice, and Pasta Group (including whole and refined grains)
1 slice of bread
About 1 cup of ready-to-eat cereal
1/2 cup of cooked cereal, rice, or pasta

Vegetable Group
1 cup of raw leafy vegetables
1/2 cup of other vegetables, cooked or raw
3/4 cup of vegetable juice

Fruit Group
1 medium apple, banana, orange, or pear
1/2 cup of chopped, cooked, or canned fruit
3/4 cup of fruit juice

Milk, Yogurt, and Cheese Group
1 cup of milk or yogurt
1 1/2 ounces of natural cheese (such as cheddar)
2 ounces of processed cheese (such as American)

This group includes lactose-free and lactose-reduced milk products. One cup of soymilk with added calcium is an option for those who prefer a nondairy source of calcium. Choose fat-free or reduced-fat dairy products most often.

Meat, Poultry, Fish, Dry Beans, Eggs, and Nuts Group
2 to 3 ounces of cooked lean meat, poultry, or fish
1/2 cup of cooked dry beans or 1/2 cup of tofu counts as 1 ounce of lean meat
1 2-1/2 ounce soyburger or 1 egg counts as 1 ounce of lean meat
1/3 cup of nuts counts as 1 ounce of meat
 
 
A Few Points to Consider:

An amount considered a serving size on a product's Nutrition Facts label may be larger than specified in the guidelines recommended above.
Dry beans, peas, and lentils can be counted as servings in either the meat group or the vegetable group. As a vegetable, 1/2 cup of cooked dry beans counts as 1 serving. As a meat substitute, 1 cup of cooked dry beans counts as 1 serving (2 ounces of meat)

Thanks Shelby, this is great information. I always wondered about the serving sizes and I always try to eat the right amount of fruits and vege's. It seems easier for me to eat the fruit than the avege's. With this guide, it will be beneficial for me to follow it.
Have a great day.
