My wife cooks vegatables with lean beef with olive oil i eat then when i go to work i have peanut butter and jelly sand with whole grain breadhealthy?

Yes: That sounds very healthy. Now exercise and don't smoke and you are well on your way to a better you.

It depends: I consider most beef, from cows in feedlots feed GMO corn and given hormones and antibiotics, to be VERY unhealthy but grass-fed beef without hormones/antibiotics is quite healthy, so buy that type! Better to cook with coconut oil. Choose organic peanut butter and organic whole grain bread; this is OK unless you are sensitive to gluten. I advise some salads and fruits in your diet as well.
