Research Confirms Your Brain’s Pleasure Response Altered
A massive debate rages on about health implications of artificial sweeteners & whether they could be linked to obesity, cancer, and Alzheimer disease. It’s a good conversation to have because noncaloric sweeteners are consumed regularly in chewing gums, frozen dinners, yogurts, vitamins, baby food, and particularly in diet sodas.
As research delves deeper into these issues, scientists are gaining a greater understanding of how sweet synthetic alternatives such as Splenda impact the brain. From engagement mechanisms of the brain’s central taste pathways, to uniquely altering the food reward-system response, we are learning that substituting one sweet taste for another by switching from sugar to artificial sweetener does not fool the brain. This brilliant organ knows the real deal even if your taste buds can’t detect the difference.
Taste & reward signaling in the brain is immensely complex. Research is only beginning to understand how altered brain activity with prolonged use of artificial sweeteners may impact our health long-term. While previous studies have shown an association between obesity and decreased caudate head activation during food-reward tasks, a link between artificial sweeteners altering brain activity in the caudate head and obesity has not yet been established.
