British Heart Foundation says: “It’s well known that added sugar has a harmful effect on our health, in particular because consuming too much of them can lead to excess weight, which can harm our heart and circulatory system.

“This has led to artificial sweeteners being used as a low-calorie sugar alternative in many foods and drinks.”

The sweetener consists of two amino acids known as aspartic acid and phenylalanine, which can be toxic when ingested in large amounts.

More specifically, phenylalanine has been linked to the development of headaches, anxiety and depression, and aspartic acid is believed to cause fatigue, confusion and memory loss.
