Ask the dietician: Genevieve Jardine
From our community: “My daughter is on insulin injections and can’t inject for every cold drink she wants. Everybody says aspartame is bad for you, so what can she drink except water?” Di-ann Reid.
A lot of the excess sugar in our diet comes from drinks that are high in sucrose and fructose: regular fizzy drinks, energy drinks and also fruit juices. These not only have an effect on blood sugar, but also increase overall energy intake, which can lead to weight gain. That’s why these drinks aren’t a good idea for diabetics.
So what else can you drink?
Artificially sweetened diet drinks
These are pretty much kilojoule free and don’t raise blood sugar levels, but most of them contain aspartame – the topic of a lot of debate for many years. Although aspartame has been linked to increased risk of cancer, mood disorders and even diabetes, nothing has been proven and the FDA (Food and Drug Administration) has approved diet drinks with aspartame, with a limited daily intake. So it’s a good idea to reduce the number of artificially sweetened drinks you have, especially if you’re using other sweeteners in tea and coffee.
These often confuse people with diabetes, because they say “no sugar added” on the label. Although there is no added sugar, fruit juices are high in fructose sugar that can push up blood glucose levels. They are a concentrated form of natural sugar from the fruit – you get all the sugar, but none of the fibre that’s good for you. A small glass of fruit juice can have twice as much sugar as a piece of fruit!
Tip: When looking at food labels, always check the total carbohydrate content (per serving size) and not just the sugar content.
Here are some ideas for drinks with and without artificial sweeteners:
One-a-day drinks – low carb, with artificial sweeteners
- Diet fizzy drinks (Tab, Coke Light, Coke Zero, Sprite Zero, Fanta Zero etc.)
- Diet cordials (Brookes Low-Cal etc.)
- Light iced teas (Lipton Iced Tea Lite etc.)
- Light flavoured mineral water (aQuelle Lite etc.)
Everyday drinks – low carb, no artificial sweeteners
- Freshly squeezed lemon juice in ice-cold water.
- Hot or cold flavoured herbal teas (no sugar added).
- All unflavoured sparkling water.
- Chopped up fruit pieces (like strawberries, lemon or orange) soaked in water for the fruity flavour without the sugar.
Treat drinks – medium carb
These drinks have 6 to 8g of carbohydrate per serving – half the amount of normal drinks!
- 200ml tomato juice (low GI).
- 150ml Lamberti’s low GI juice.
- 100ml Energade Champ (low GI).
