physically, these can cause aggression because they affect the nervous system:
Dehydration (nerves run on HYDRO electricity.) Your nerves go into a aggrivated state and certain avenues in the body have to literally shut down to preserve the water for the brain and heart (survival organs) when your system is low on fluid.
Magnesium deficiency - Magnesium is a chemical gate blocker for calcium to not rush into the nerve and excite it. MG affects 300 functions in the body. A deficiency causes increased adrenaline. Magnesium citrate is the most quickly absorbed. Magesium oil can be absorbed throught he skin. Both can be used at once.
Too much milk can deplete calcium and magnesium, both.
Too much Soy can affect the hormones, the thyroid, and serotonin.
Look for soy in any form in the ingredients list:(soy lactate, soy isolate, soy protien or teqtured soy protien, soybean oil, soy extract, soy sauce, soy casienate, etc) http://www.crimetimes.org/04c/w04cp6.htm
MSG- can cause agression. www.life-enthusiast.com/index/education/nutritionAvoid/ms...

Too much iron can cause aggression. Watch for iron fortified foods and cereals. Iron is a HEAVY METAL. Other heavy metals will also cause agression: mercury, lead.
HFCS, (High fructose corn syrup) is loaded with mercury.Almost every processed, manufactered food has HFCS. In fact, trying to get away from SOY and HFCS and MSG is just about impossible in any processed food.
Fodd sensitivities and allergies to these added toxins, plus chemical imbalances caused by them probably account for a high percentage of behavior issues in children and even adults.
