A new study suggests that regular use of artificial sweeteners may impair blood-sugar control. The latest findings suggest consuming even less than half the amount approved by health authorities is not safe.

For the study, participants who don’t normally use the sweeteners were assigned to use 45 per-cent of the Health Canada acceptable daily intake (ADI). After only 14 days, these participants experienced an 18 per-cent reduction in insulin sensitivity, a risk factor for type-2 diabetes.

Sucralose, aspartame, acesulfame potassium, cyclamate and saccharin are zero-calorie sweeteners approved in Canada.

Cyclamate (brand names Sucaryl, Sugar Twin, Sweet’N Low) and saccharin are not allowed to be added to foods; they’re sold only as tabletop sweeteners.

Acesulfame potassium, aspartame and sucralose are allowed to be added to all sorts of foods including yogurt, baked goods, pancake syrup, ketchup, chewing gum, fruit juice and soft drinks. Sucralose (Splenda) and aspartame (Equal) are also available as tabletop sweeteners.

Health Canada considers these five artificial sweeteners safe when consumed in amounts up to the acceptable daily intake (ADI). The ADI is the maximum amount thought safe to consume each day over a lifetime.
