Scientists are debunking the link to hyperactivity

Contrary to decades of popular belief (and anecdotal evidence from generations of parents), a new study has found that there is no such thing as a sugar rush. That’s right. The sugar rush is a myth. Rather than making people feel energized and hyped, the new research suggests eating sweet foods actually causes people to experience the opposite: fatigue and a lack of alertness.

The results — which were published in June in the journal Neuroscience and Biobehavioral Reviews — come from a meta-analysis of 31 published studies involving almost 1,300 people.

Scientists have found that two compounds can boost endurance in mice by changing the metabolic properties of the animals’ muscle. One of the drugs appears to mimic some of the benefits of exercise even in sedentary mice.

Cure for Jet Lag – Starve Yourself

 Cure for Jet Lag - Starve Yourself

 Sometimes the cure is worse than the disease

Starving yourself before a long flight may help prevent jet lag, US researchers said on Thursday.

Normally, the body’s natural circadian clock in the brain dictates when to wake, eat and sleep, all in response to light. But it seems a second clock takes over when food is scarce, and manipulating this clock might help travelers adjust to new time zones, they said.
