Aspartame is a widely-used artificial sweetener.
It is commonly used in products like sodas, candies, and sugar-free syrups.
Many people use aspartame because of its calorie-free sweetness, which helps to reduce calories and manage blood sugar levels.
Consuming foods that contain aspartame can lead to side effects like headaches, gastrointestinal symptoms etc.
The controversy over aspartame is based on studies with animals that prove it may cause cancer to humans.
Some studies in animals have raised concerns, but regulatory agencies like the FDA maintain that aspartame is safe within recommended daily limits.
