Add some fruit to your morning cereal instead of choosing sugar filled ones. Buy a plain cereal and then add fresh strawberries, bananas or blueberries to get that sweetness you crave. Sugary kids' cereals will only leave you with a crash later. Fresh fruit will fill you up better and not cause you to crash later.
It is important to get enough iron in your diet, because it is used for oxygen transport throughout the body. If you do not get enough, you will suffer from anemia. Good sources of iron include meat, particularly organ meats like liver, dark leafy vegetables such as spinach, and molasses.
