All About Sugar

Posted on

Sweet potato & spinach omelette

The Scientific Advisory Committee on Nutrition (SACN) recently examined the relationship between dietary carbohydrates and health. The review found that an increased consumption of sugar is linked with tooth decay, higher energy intakes, type 2 diabetes; and consumption of high sugary drinks is associated with increased weight gain in teenagers and children. As a result of these findings SACN recommends that we consume no more than 5% of free sugars from our total daily dietary intake.

What are free sugars?

Free sugars are those added to food including those naturally present in honey, syrups and unsweetened fruit juices. Sugar found naturally in milk, fruit and vegetables does not count as free sugars.

How much free sugar can we consume per day?

Seven sugar cubes 30g per day for those aged 11 onwards.

Six sugar cubes 24g per day for children aged 7-10

Five sugar cubes 19g per day for children aged 4-6

 Hidden sources of sugar

Free sugars are also found in foods such as biscuits, sweets, cakes, chocolate, some fizzy and juice drinks. These are the sugary foods/drinks we should cut down on.

 Useful tips on how to cut back on sugar

  • Drink water instead of fizzy drinks and cordial drinks
  • Reduce the amount of sugar you have in your tea or coffee
  • Try herbal teas
  • Read the ingredients on products and look out for hidden sugars such as syrups
  • Try plain oat or wheat based cereals
  • Opt for no added sugar drinks
  • Remember only 150ml glass of fruit juice counts as one of your 5 a day
  • Include fresh fruit into your diet and try adding it on cereals for natural sweetness
  • Try plain yoghurt with fresh fruit instead of fruit yoghurt which can contain free sugars
  • Read food labels- opt for anything which is 5g per 100g or below of carbohydrates of which sugars.
  • If you have jam, chocolate spread or honey on toast, apply a thin spread or swap it for peanut butter, cheese or eggs on toast
  • Try oatcakes, bread sticks with a dip or raw fruit and vegetables as a healthy snack instead of a sugary snack

Healthy recipe – Sweet potato and spinach omelette


8 eggs

600g sweet potato peeled and cut into 2cm cubes

40g baby spinach

2 tbsp rapeseed oil


Black pepper


Fresh coriander (optional)


Preheat oven to 200°C or 180°C fan. Line a baking tray with baking paper. Place sweet potato on prepared tray and drizzle with one tbsp of rapeseed oil. Bake for 20–25 minutes or until golden. Transfer to a large bowl and set aside to cool slightly. Add spinach and coriander, season and toss gently to combine.

Meanwhile, whisk eggs in a medium bowl until combined. Season with pepper. Add one tbsp of rapeseed oil to the non-stick frying pan and heat over medium heat. Add one-quarter of the egg mixture and cook for 10 seconds. Using a spatula, draw edges of omelette into centre, allowing uncooked mixture to run underneath. Repeat until egg mixture is nearly set. Transfer to a plate and cover to keep warm. Repeat with remaining egg mixture to make 3 more omelettes. Spoon one-quarter of the sweet potato mixture onto half of each omelette. Fold to enclose filling. Serve.
