White Flour
White flour has had all the good stuff, like bran and nutrients, removed. Your body treats it pretty much like sugar and easily converts it into glucose.
Anything made with refined carbohydrates doesn’t help your workout goals. Refined carbs include breads, pastries, donuts, bagels and anything breaded. You can eat healthy bread – whole grain flour retains the good stuff and will take your body longer to break down.
Carbs are important after workouts and your body needs the energy. Just chose the best ones.
