the my plate sets what the standard on what healthy habits should be in a 2000 calorie diet, when it comes to vegetables, try varying it, any vegetable or vegetable juice counts as a vegetable, fill half your plate with vegetables.
fruits should be one of the main focus in your plate, a whole fruit is preferable to juice but juice still would work, try to maintain it as natural as you can, fill your other half with fruits.
make at least half your grains whole, look at labels to find more whole grains like whole wheat and oatmeal.
go lean with protein, make it take up 1/4 of your plate, nuts, beans, seeds, poultry, lean meat, seafood, soy and eggs are good examples of this group
dairy is your main source of calcium, remember to choose 1% and skim milk over whole milk, try non fat yogurt as a snack, keep choices low on fat sodium and sugar.
