Steel-Cut Oats Healthiest, Instant Oats Least Nutritious
Oats come in different types: steel-cut, rolled, and instant.
Steel-cut oats are the least processed and healthiest, with a low glycaemic index, meaning they don't spike your blood sugar quickly.
Rolled oats are a good middle option, easy to cook and still healthy.
Instant oats are the most processed and can cause blood sugar to rise quickly.
All oats contain a special fibre called beta-glucan, which helps keep your heart healthy.
If you're trying to manage diabetes or lose weight, steel-cut oats are the best choice.
Rolled oats are great for a quick, balanced breakfast, while instant oats should be eaten sparingly and with added nuts or seeds to slow down sugar absorption.
Steel-cut oats are the least processed and healthiest, with a low glycaemic index (52-53).
Rolled oats are steamed and flattened, cooking in 5-10 minutes, with a medium glycaemic index (55-57).
Instant oats are highly processed, cooking in under 2 minutes, with a high glycaemic index (75-83).
All oats contain beta-glucan, a soluble fibre that helps trap cholesterol and improve heart health.
Steel-cut oats are best for weight loss and diabetes management, while rolled oats offer a balanced, versatile breakfast option.
