Carbohydrates are broken down into glucose which we are able to use as a source of energy. Refined carbohydrates such as white bread, pastries, bagels and cereals are often laden in sugar and will cause your sugar levels to spike, only providing you with energy for a few short hours. Swap these foods with high fibre or whole grain varieties, which are much more slow releasing: brown rice, wholemeal, quinoa, oats and starchy vegetables such as potatoes. This will really help to balance blood sugar levels, keep you full for longer and sustain your energy through the day. Be aware that many ‘healthier’ options available on supermarket shelves often contain high amounts of hidden sugars disguised under alternative names!
