Why We Crave Sugar

“ It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change. ” – Charles Darwin

If sugar wasn’t sweet, we wouldn’t eat it, but have you ever wondered why that is? Why do we crave sweet things, and not bitter things? Why do we feel the need to visit McDonalds to buy a large Mcflurry instead of a something nutritious like an apple? Why do we celebrate important occasions with sweets like cakes, and not celery? Evolution can shed some light on this.

It Was Rare

Our ancestors lived in a world where food was hunted, and gathered, hence the name hunter-gatherers. This means that the foods they were probably consuming were no sweeter than a carrot. They were not exposed to donut trees, or chocolate vines. The delicacies that were even remotely close to the sweets of today were mostly regarded as extremely rare, and special.

If someone in the Paleolithic era was fortunate find something that tasted sweet, their brain fired up, and screamed, “Eat more!!” That reaction served them well because the sugary fruit served as an energy source for long walking trips, hard labor, or just getting through the day.

Sugar Makes Memories Sweet

Fast forward to today, and we can understand why people use cakes to celebrate birthdays. It’s a special day that only comes around once a year, so you could say it’s rare. So, what better way to celebrate than eating something delicious? Sweets tell your body how you should be feeling on a birthday, or special event: happy, and excited!
