Eggs Are Good for You

A good proportion of most GPs’ consultations will involve some sort of conversation and advice about cholesterol.

It’s certainly one of the tests that patients ask for most. And yet many doctors and health professionals are still giving out incorrect advice when it comes to diet and cholesterol-lowering measures, and the public’s knowledge on the subject is poor at best.

This is concerning considering that research done many years ago quite definitively demonstrated that dietary cholesterol, from foods such as eggs and shellfish, has only a small and clinically insignificant effect on blood cholesterol. For most people, it’s the amount of saturated fat they eat that has a far greater impact on their cholesterol levels than eating foods that contain cholesterol, such as eggs and shellfish. Yet the advice so often still given is to cut down on cholesterol-containing foods, and as a result many people still believe that there are restrictions on the number of eggs  Continue reading

Anxiety Can Be Controlled by Flashes of Light to Brain

Stimulating certain parts of the brain with pulses of light could prevent feelings of anxiety, US researchers claimed.

Scientists from Stanford University pinpointed the neural circuit that controls anxious behavior in mice and were able to manipulate it using light, according to research published Wednesday.

During tests, the amygdala region of the mice’s brains was exposed to specially-structured fiber-optic cables, and depending on which cells were exposed to the light, the mice became less fearful of their surroundings or more inhibited.

Rodents usually try to avoid wide-open spaces that could expose them to predators, but during simulations, the mice were much more willing to explore open areas when light was pulsed into the brain circuit.

The scientists were also able to make the mice more anxious by deactivating the cells with a different light frequency.

The human brain is structured in a similar way to those Continue reading
