Sugar is not an illicit drug, but the brain acts in a similar manner to other substance abuse and addictions. One of the first and most noticeable causes of sugar addiction is that the brain wants sugar. The brain needs glucose as a fuel source and your brain will continuously attempt to get glucose as a way to prevent a potential shortage of this nutrient. Another reason you could be craving sugar regularly is due to how it makes you feel after consuming it. Generally, a sugary treat causes a rush of both glucose and endorphins in your blood, which initially causes a short burst of energy. However, the euphoria you get from eating sugar does not usually last for too long. It can cause a fast crash in your energy levels, which can cause you to feel lethargic, weak, and potentially even depressed, all due to a sharp decrease in your blood sugar levels. This leads to a vicious cycle that may have you craving sugary foods. Consider taking a look at our guide discussing in greater depth the causes of sugar cravings. Let’s face it, sugar tastes great, and this is part of the reason why you may be hooked on it as well. Your taste buds are small receptors located on your tongue and inside your mouth, and they respond to various substances that you consume. Interestingly, if your taste buds are not working properly, you could have a stronger affinity towards sugar and sugar addiction.
