Our bodies convert carbohydrates into glucose so they are
essential for maintaining balanced energy levels. On an average
day the brain uses 40% of all carbohydrates consumed. An imbalance
may create fatigue, irritability, depression, crying spells,
digestive disturbances, dizziness, insomnia, excessive thirst,
poor concentration, forgetfulness, excessive sweating and
blurred vision.
Complex carbohydrates (eg brown rice, vegetables, beans,
lentils and fruit) take longer to digest than refined carbohydrates
so when eaten, your body digests them and releases their potential
energy steadily and gradually.
The Glycaemic index shows how fast or slowly foods release
energy. The effects that different foods have on your blood
sugar are compared against pure glucose, where glucose has
a value of 100. You need low GI levels to sustain energy and
concentration throughout the day. Foods with a GI score below
50 are best. |
