The problem with biscuits
Most biscuits cost a lot of kilojoules for a very small portion. For example, two cream-filled biscuits supply 860 kilojoules. Yet a medium apple, which is much more filling, provides only 315 kilojoules—less than half that amount! Being made of finely ground white flour (or sometimes wholemeal), biscuits are usually high GI , meaning they provide the wrong type of carbohydrate, causing blood sugar to rise rapidly then fall—basically, a quick-hit effect without the sustaining energy you need to get you through the afternoon. For this reason, high-GI , low-fibre foods are undesirable for weight control. Such foods are also linked with an increased risk of type-2 diabetes, certain cancers and even heart disease.
The amount and type of fat hidden in biscuits is also alarming. For example, two shortbread biscuits provide around 10 g fat, which is one-quarter of the daily allowance of a low-fat diet! More concerning is that the type of fat (often from butter or hydrogenated vegetable oil) is nasty, being saturated or trans fat.
These fats are known to increase insulin resistance and raise blood-cholesterol levels and therefore promote disease.
