Problem: Sweet Foods Don’t Taste As Sweet Anymore
A funny thing happens when you start to cut sugar from your diet: sweet foods start tasting sweeter. You’ve probably experienced this phenomenon without even realizing it. Think about what happens when you take a sip of orange juice after eating a pastry. That bitter taste results from your taste bud’s inability to taste slightly sweet after tasting very sweet. Your brain recognizes and adjusts to tastes as you eat.
After eating something super sweet, your brain expects the same taste, which makes the juice register as much less sweet or even sour. This is also why sweeter wines are typically paired with desserts. Over time, eating tons of sugary foods will make your brain continuously perceive foods as slightly less sweet than they really are. One study found that rats on a high-sugar diet for four weeks had reduced sugar sensitivity. Fortunately, the researchers found that the effect could be reversed by switching back to a normal, low-sugar diet.
