Pleasure and timing are interlinked, not only in life but in our body as well, finds a recent study. The brain's pleasure sector has an integrated connection with the human biological clock. Thus, high-calorie food, which makes one happy and content, can disturb one's regular schedule without even being noticed before it's too late. As a result, overweight and obesity are a compulsion. But that is not all that comes with happiness through overeating. One can be prone to diabetes, heart diseases, hypertension and even cancer due to ill-eating habits. According to the study, the eating pattern in the United States has worsened in the past 50 years. "With highly processed foods readily and cheaply available at any time of the day or night," Ali Guler, a professor of biology at the University of Virginia, said. "Many of these foods are high in sugars, carbohydrates, and calories, which makes for an unhealthy diet when consumed regularly over many years." Guler and his co-workers, in the study published in Current Biology on Thursday, described that the portion of our brain that excretes dopamine and the other part determining the human clock are synced. Guel and his team had used mice to conduct the study and reach such result. "We've shown that dopamine signalling in the brain governs circadian biology and leads to consumption of energy-dense foods between meals and during odd hours," said Guler.

Often used as an alternative to traditional smoking, e-cigarettes (EC) come with their own health risks. E-cigarettes produce a stress response in neural stem cells, which are critical cells in the brain, finds a study. The study published in the journal 'iScience' used cultured mouse neural stem cells and identified the mechanism underlying EC-induced stem cell toxicity as 'stress-induced mitochondrial hyperfusion,' or SIMH. "SIMH is a protective and survival response. Our data show that exposure of stem cells to e-liquids, aerosols, or nicotine produces a response that leads to SIMH," said Prue Talbot, lead researcher of the study.Talbot stressed that youth and pregnant women need to pay especially close attention to their results. “Their brains are in a critical developmental stage," said Talbot.
