In reality, even though we watch our diet, blood sugar is not a perfect science. However it is known that some foods are more influential than others. These foods are mostly carbohydrates - and they can affect more than just our blood sugar. Carbohydrates can affect our moods and appetite through a neurotransmitter called serotonin.

Serotonin is unique in that it is indirectly controlled by foods, specifically carbohydrates. It's not surprising that eating foods like chocolate cake and potato chips can lift your spirits for a moment or two - but the aftermath doesn't always seem as exhilarating. This becomes a fattening trend, after a while. Why do we get a spiritual uplift from indulging in these no no yum yums?

There is an explanation for this fattening fix. Different sugars affect the brain in different ways. Beware of sugars that are more processed like: glucose, dextrose, and sucrose. These sugars enter the bloodstream quickly, reaching high levels in a short time. This triggers the release of large amounts of insulin. The evolution of man has not adapted for highly refined sugars. This type of sugar is quickly ushered to the cells. Depending on how active a person you are - this energy may not be used up and therefore results to fat storage. A good indicator to use when choosing carbs is the glycemic index. The lower you stay on the index, the less the overall impact on your blood sugar rise. Checkout Fifty50 glycemic index for a list of everyday foods.
