Protein vs. Carbohydrates

I think  most people will agree, there is a big controversy surrounding these two food groups. Some argue you need more carbs and less protein and others believe its more protein and less carbs. I tend to fall with the latter. I think that most people could reason out why they might want to eat one over the other if they knew a little background information.

It is well known that serotonin, dopamine and norepinephrine play a major role on mood and happiness/sadness. What most people don't know is that eating certain foods can trigger the body to make one or the other of these neurotransmitters. So, which foods trigger which neurotransmitter?  Here is a basic model of how dopamine, norepinephrine/epinephrine and serotonin are created.

Carbohydrates --> Insulin Production --> Tryptophan --> Serotonin --> Melatonin

Proteins --> Phenylalanine --> Tyrosine --> Dopamine --> Norepinephrine --> Epinephrine  

Keeping in mind that melatonin is used as a sleep aid, serotonin production via carbohydrates will tend to cause drowsiness or less energy. Proteins are less likely to cause fatigue and loss of energy considering their products. Dopamine and norepinephrine tend to be more excitatory and will most likely boost energy levels. Fortunately, serotonin can also be produced with protein rich foods that do not drastically affect insulin levels such as dairy, red meat, fish, poultry, seeds and peanuts. These foods will have a great benefit because they will target serotonin production, dopamine production and norepinephrine/epinephrine production without causing drowsiness. Complex carbohydrates, such as vegetables, will also be beneficial in controlling insulin levels, and are less likely to cause fatigue.

Some people prefer to also supplement with the amino acids Tyrosine and Tryptophan that can be located at a local health food store. I would advise you talk to your doctor because while these are 'natural', they make interact with your existing medications.
