Iron-rich foods can wake you up

Here are some things to remember about iron and iron absorption:
Iron absorption is enhanced in the presence of Vitamin C, so make sure you're getting enough Vitamin C
Avoid caffine as much as possible, as it interferes with iron absorption
Avoid drinking excessive milk with meals to maximize iron absorption
Complex carbohydrates are also excellent energy boosters. The best sources of these are grain products and fruits.
Foods that provide fat are another good source of energy (Just make sure it is a "good fat", not saturated!). Some good sources of "good fats" are: nuts and nut butters, unrefined oils, such as olive oil, avacados, and cold water fish (salmon, for example).
