Is your sweet tooth caused by genes or self-inflicted?

The constant craving for sweets might actually be explained by the sweet tooth gene! Sugar lures sweet-toothed individuals toward the treat aisles of the store. According to genetic heritage, even 50% of Northern Europeans have a slightly increased tendency for sweet cravings. In addition, about 20% of us experience an almost irresistible pull toward sweets.

So, it’s highly likely that we all have at least some tendency toward sweetness. Do you already know which parent you inherited your sweet tooth genes from? Or can you even blame both? Taste preferences related to food are partly hereditary, but many are also simply slaves to their habits.

Is sugar addiction really just hunger?

The pleasure we get from delicious foods is driven by the brain’s reward system, which associates enjoyment with certain foods like sugar. While there is no scientific evidence for true sugar addiction, some people turn to sugary treats when they’re on the verge of exhaustion to quickly boost their blood sugar. However, this rapid spike is usually followed by a sharp drop, and the cycle of fatigue continues.

If you want to maintain stable energy levels and feel more energized throughout the day, it’s worth considering whether you’re getting enough protein with each meal. Do you eat regularly, or do you have a long break in the afternoon, leaving you hungrier than expected? Craving sweets can often simply be a sign of not eating enough.

The liver’s role in sweet cravings

FGF21 is a hormone produced by liver cells from the gene of the same name. Lower levels of this hormone have been linked to an increased consumption of sweets. Its effect is specifically tied to the pleasure response caused by sugar and sweeteners. Interestingly, this gene does not influence cravings for salty snacks.
