How much should I be eating?
There are two types of sugar - naturally occurring sugar like lactose in milk and added or 'free' sugars, which include table sugar (sucrose) as well as concentrated sources like fruit juice. It is these 'free sugars' which are any sugars added to food or drinks, or found naturally in honey, syrups and unsweetened fruit juices which we are being advised to cut back on.
The new recommendations from the World Health Organisation (WHO) and the UK's official nutrition advisors are that only 5% of your daily calorie intake should consist of added, or 'free' sugars. This equates to approximately seven sugar cubes (30g). Children should have less - no more than 19g a day for children aged 4 to 6 years old (5 sugar cubes), and no more than 24g (6 sugar cubes) for children aged 7 to 10 years old.
The devil's in the detail
The instant 'lift' we get from sugar is one of the reasons we turn to it at times of celebration or when we crave comfort or reward. However, even those of us without a sweet tooth may be eating more than we realise because so many everyday processed foods, from cereals and bread to pasta sauce and soups contain sugar.
But it's not all bad news - sugar is a carbohydrate found naturally in a host of different foods from lactose in milk to the fructose in fruit and honey. In fact, if you're very active and exercise regularly some sugar in your diet helps supply ready energy to fuel your muscles and keep your brain active. The problem for the majority of us is that many of the processed foods we eat have added sugar which supplies energy in the form of calories, and very little else - so we end up consuming more than we need.
This means our body has to draw on the nutrients from the rest of our diet to process the sugar and this can affect our health, including our immunity - leaving us more prone to bugs and colds. A high intake of sugar causes our blood sugar levels to shoot up, giving us that feel-good 'high' followed by a crashing slump which leaves us tired, irritable and craving more sugary foods. It's a vicious cycle that may be contributing to our weight problems as well as health conditions like diabetes and heart disease.
Spot the hidden sugar
• Low-fat and 'diet' foods often contain extra sugar to help improve their taste and palatability and to add bulk and texture in the place of fat.
• Even savoury foods, like ready-made soups and sauces may contain added sugar.
• A can of soft drink, on average, contains the equivalent of seven teaspoons of sugar.
• The natural sugar in some fruit, including apples, has increased as new varieties (including Pink Lady, Fuji and Jazz) are bred to satisfy our desire for greater sweetness.
Ways to cut down on your sugar
Making a few adjustments to your diet can help you cut down on unnecessary sugar consumption:
• Reduce the sugar you add to hot drinks. Do so gradually to give your taste buds time to adjust. Try adding a sprinkle of cinnamon to cappuccino or hot chocolate, cinnamon helps stabilise blood sugar levels and adds flavour without the sweetness.
• Avoid low-fat 'diet' foods which tend to be high in sugars. Instead have smaller portions of the regular versions.
• Be wary of 'sugar-free' foods. These often contain synthetic sweeteners like sucralose, saccharin and aspartame. Although these taste sweet, they don't help curb a sweet tooth so they tend to send confusing messages to the brain, which can lead to over-eating.
• Balance your carb intake with lean protein like fish, chicken and turkey - protein foods slow stomach emptying, which helps manage cravings.
• Swap white bread, rice and pasta for wholegrain versions like oats, granary and wholemeal breads, brown rice and pasta.
• Reduce the sugar in recipes and add spices to boost flavour and taste.
• Stick to one glass of fruit juice a day (and dilute it) and keep sweet soft drinks and alcohol for the weekends. Enjoy herbal teas or water with slices of citrus fruits for flavouring.
• For a pick me up, have a piece of whole fruit with a handful of nuts or a small tub of plain yogurt. Both contain protein which helps balance blood sugar and energy levels.
