Packed with fibre or full of sugar? A dietitian rates popular supermarket oats

Oats are super healthy but bland and stick to the saucepan. These flavoured, convenient varieties may make porridge more appealing – but are they good for you?

Susie Burrell

When it comes to breakfast foods, you will be hard-pressed to find a better option nutritionally than oats. A natural wholegrain, oats are one of the most satiating foods we can enjoy.

Naturally high in dietary fibre, and offering a range of key nutrients including vitamin E, protein and zinc, a bowl of oats teamed with yoghurt or milk is one of the few breakfast options likely to keep you satisfied until lunchtime.

Like many supermarket foods, though, there is an increasing range of flavoured and quick-cook oat options to choose from, especially if you enjoy your oats with a little more flavour.

Oats are oats

The first thing to know about oats is that plain rolled oats are the same product, no matter which brand you buy. While steel-cut oats are slightly better nutritionally, as they release glucose more slowly into the blood stream, whole, rolled oats remain one of the strongest options nutritionally, and can retail for as little as $2 per 750g bag.

What about “quick cook”?

Quick-cook varieties are slightly more processed than whole rolled oats, but again still a good option, with no significant difference nutritionally between brands. For this reason, all plain oats are ranked as the top choice nutritionally, better overall than flavoured varieties that generally have sugars added.

Another variant you may see are stabilised oats. These oats have been processed to minimise the action of naturally occurring enzymes that would otherwise cause the oats to naturally lose their freshness. Stabilised oats will keep fresher for longer, but are slightly more processed than natural, unstabilised oats.

What about added sweetness?

Some would argue that oats are simply not appealing without a little added sweetness — honey, brown sugar, maple syrup or fruit to make the oats a little more appetising. As oats are already carbohydrate rich, adding a tablespoon of sweetness via added sugar or even with fresh fruit doubles the carbohydrate content of this meal.

For active people, or those who do not have blood glucose issues, this is no cause for concern, but if you need or choose to keep your carb and sugar intake controlled, lower sugar options that still offer sweetness include vanilla, cinnamon, low-sugar syrups or berries or passionfruit, which are all relatively low in sugar compared with dried fruit.

Alternatively, sweetened options that contain less than 5g of total sugars overall are still relatively low in sugars.
