Heavy use of six sugar substitutes linked to faster brain ageing

A study of nearly 13,000 adults, published in Neurology, found those consuming the most low- and no-calorie sweeteners saw a 62% faster decline in memory and thinking, equal to about 1.6 extra years of brain ageing. Six of the seven sweeteners examined showed links. The association was stronger in people with diabetes, though researchers stress causation was not proven.
