GLUCOSENEUROLOGYSome hypothalamic neurons can be activated by glucose, but the functional significance of this capacity was unclear. Parton et al . now show that glucose-sensing pro-opiomelanocortin (POMC) neurons in the hypothalamus play a part in the regulation of systemic glucose levels, and ...
The mammalian brain depends on glucose as its main source of energy. In the adult brain, neurons have the highest energy demand [1], requiring continuous delivery of glucose from blood. In humans, the brain accounts for approximately 2% of the body weight, but consumes approximately 20% of ...
Is Sugar Sabotaging Your Brain? Sugar. What a love-hate relationship we humans have with the sweet stuff. It tastes so good to our tongues (so good that it can be addictive), but we know that it’s so bad for our bodies. In recent years, the overconsumption of added sugar has been...
A diet high in fat and sugar actually affects the parts of the brain that are important to memory and makes people more likely to desire unhealthful food,says American psychologist Terry Davidson.Davidson didn't start out by studying people's eating. Instead, he was interested in learning abou...
When we eat or drink sugary foods, the sugar enters our blood and influences parts of our brain that make us feel good. Then the good feeling goes away, leaving us wanting more. All tasty foods do this, but sugar has a particularly strong effect. In this way, it is in fact addictive...
Do you often crave sweets? Binge on carbs? WebMD's slideshow offers a peek into your brain on sugar -- and tips on how to tame a sweet tooth so you can lose weight.
Guided by gut sensory cues, humans and animals prefer nutritive sugars over non-caloric sweeteners, but how the gut steers such preferences remains unknown. In the intestine, neuropod cells synapse with vagal neurons to convey sugar stimuli to the brain within seconds. Here, we found that cholecy...
by Allen Institute for Brain Science Although brain growth slows as individuals age, some regions of the brain continue to develop for longer than others, creating new connections and remodeling existing circuitry. How this happens is a key question in neuroscience, with implications for brain ...
"Sugar,we believe,is one of the main reasons," says Johnson. Our bodies are designed to live on very little sugar.Early humans often had little food,so the bodies learned to keep sugar as fat.In this way,we had energy when there was no food.But today,most people have more than ...
When we eat or drink sugary foods, the sugar enters our blood and affects parts of our brain that make us feel good. Then the good feeling goes away, leaving us wanting more. In this way, it is addictive. So what should we do? It's obvious that we need to eat less sugar. But ...
