Eating small healthy snacks can help improve your overall physical and mental condition by preventing extreme blood sugar dips between meals.

In fact for some of us five small meals may be better than three large ones. Believe it or not the right snacks can help rev up your metabolism, regulate your mood swings and provide the boost to aid concentration and energy flow.

Lack of food can throw the switch and click the metabolism into famine mode, slowing it down and making it easier to gain weight.

Snacks with carbohydrates are often the food of choice for athletes looking to go that extra mile. They do lift the mood by boosting production of the neurotransmitter seratonin, giving feelings of happiness and well-being.

However, try to avoid refined processed foods and move towards snacks made with wholegrains, maple sugar, fruit and vegetables. These lift the mood gently without the roller-coaster effect.
