Preface
Yesterday I was enjoying some quality cuddling time with my cat. And I was thinking of how he is so awesome - he's a gorgeous domestic longhair with quite a personality and strangely, a wicked sweet tooth. Cupcakes are his favorite, no joke. So, naturally, I began to think about what really determines one to "have a sweet tooth". After our cuddling session, I went on the internet and did some "research". Having gone to school for nutrition and FOOD SCIENCE you might think I would know the answer. Pssh...that was like 3 years ago, I have totally forgotten all that by now. (I can't even remember what I did yesterday.) Anyway, browsing through the internet I have discovered a few theories as to why we crave sweets. Here they are:
Chapter 1
Family tradition or cultural influences
Makes sense, right? When you are young, its a treat to go get ice cream. Or maybe you and your mother would bond over baking cookies Friday nights watching episodes of Sabrina the Teenage Witch (*wink wink*). Not to mention the holidays. It's not a holiday celebration without sweets, family and food comas. So the theory is if you are raised in an environment where sweets are a common part of the cultural, you will be more likely to turn to them as a comfort food.
Chapter 2
Low blood sugar
People who are dangerously lacking certain vitamins or minerals in their diet will often obsessively crave food that contains those vitamins or minerals. Unbeknownst to them, their body is protecting itself. So when your blood sugar drops below its normal level, you might start to crave sugar to give it a quick boost. Sugars are going to be absorbed into the body faster than any other macronutrient, so consuming sugar would produce the quickest increase in blood sugar.
Chapter 3
Low serotonin levels
We have all experienced sugar cravings when we are stressed or upset. You sit down on the couch and it feels like you could eat a whole pint of ice cream (dont forget to put on the Horribly Depressing Music station on Pandora). But there is an actual biological reason that these "comfort" foods actually produce a sense of comfort. Sugar consumption can have the same effect on the brain as anti-depressents. Sugar increases the production of serotonin which is like a feel good hormone in our body. This is another example of how the body is amazing; it's an incredible self-regulating machine. You are experiencing low serotonin levels, your brain knows exactly what to do, and *ta-da* theres your sugar craving.
Chapter 4
Dehydration
Water is extremely important to the functioning of our bodies and our survival. So when you get a sugar craving your body might actually be in some degree of dehydration. It's recommended that if you get a sugar craving, or a craving of any kind, to drink a glass of water. Wait 10 to 20 minutes, if the craving goes away, you were probably dehydrated.
Afterword
So whatever the reason for our sugar cravings, it's important to not think of it as a "bad" thing. Your body might actually be trying to tell you something. And why deny yourself something that makes you happy. Afterall, you only live once, so enjoy the sweet things in life.
