When you eat food loaded with sugar, your taste buds, your brain and your gut all take notice. The activation of the reward system of the brain is not unlike how the body processes the addictive substances like nicotine and alcohol – an overload of sugar van spike the dopamine levels and that leaves you craving more. Here you can see how Nicole Avena explains why treats and sweats should be enjoyed just in moderation.
Think of warm, gooey cookies, velvet cakes, crunchy candies, waffle cones piled with ice cream. Is your mouth watering at this moment or are you craving dessert? Why is that happening? What happens in our brains that makes foods with sugar so hard to resist? Sugar is a term that is used to describe a class of molecules called carbohydrates, and it is found in a wide variety of drink and food. You should check the labels on the sweet products that you buy.
Fructose, glucose, sucrose, lactose, maltose, starch and dextrose are all forms of sugar. So are high-fructose corn syrup, raw sugar, fruit juice, and honey. The sugar is not just in desserts and candies, it is also added to yogurt, tomato sauce, dried fruit, granola bars, or flavored waters. Because the sugar is everywhere, it is really important to understand how it affects your brain. What is happening when the sugar hits the tongue? And does eating just a little bit of sugar make you crave more? When you take a bite of cereal, the sugars has activated the sweet-taste receptors, which are part of the taste buds on the tongue. Then, the receptors send a signal to the brain stem, and then it forks off into many places of the forebrain, and the cerebral cortex is one of them. Different parts of the cerebral cortex process different tastes: salty, bitter, umami, and sweet. The signal from here activates the reward system of the brain.
