The Science of Sweetness

Sugar, honey, listen up. Humans love the sweet taste of sweetness, but have you ever wondered why? What’s the evolutionary purpose behind our love for sweets? Why can we taste sweet anyway? What are those sugar substitutes really made of? And will this diet cola give me cancer?
