Does anyone know how long you can keep lana's egg whites in the fridge before they go bad? Also if they have a .5 gram of carbs in every egg white and i would being eating 8 in a serving that would be 4 grams of carbs. Does this mean i cant eat egg whites (lana's) with my fats then? I like to do egg whites with flax and water and drink it. Lastly is the 100mg of sodium in the egg whites too much if i plan on eating around 16 whites a day?
