Peanut er question?

I eat peanut er with my breakfast every morning, ( whole wheat bagel, light yogurt, cup of blueberries, gl of water and hard boiled egg ) Now I know that many store bought brands of peanut er like Kroger brand and Safeway brand arnt contain oils and such. Now i'm a very active athlete and my nutrition is very important to me, but i was wondering in the long run will the store bought brand of peanut er matter? Like for my performance and ability's in athletics? If it does should I buy the healthier more expensive brand?
