1. You could hinder your learning process and memory retention
Let’s start from the top. Your brain. When you consume copious amounts of sugar, it has a negative effect on brain neurons, particularly the ones used for making memories. In fact, a study published in the journal Neuroscience found that large amounts of added sugar can slow the production of a chemical known as brain-derived neurotrophic factor (BDNF). And when your body doesn’t produce enough BDNF, even the simplest of cognitive tasks like learning and the formation of memory become a lot more difficult.
2. Cause damage to your teeth
Moving right along, let’s talk about your teeth. When soda enters your mouth, it touches your teeth — unless you’re the type who likes to inhale your fizz, at which case, jump down to the effects on your lungs that will likely burn. But, if you’re like most people, and drink your sugary, bubbly beverage, a good portion of that liquid will end up passing through and around your teeth.
And each time it does, that sugar sticks to the already present bacteria in your mouth, allowing the acid to rise. When it does, over time, the enamel is weakened and can lead to plaque that can fester and create cavities. What’s more? The acid in soda lowers the pH levels in saliva, again stimulating the production and instance of bacteria, further eroding your teeth.
