It has been estimated that the average human brain contains about 100 billion neurons and, on average, each neuron is connected to 1000 other neurons. This results in the generation of vast and complex neural networks that are the mainstay of the brain's processing capabilities. Neurons are the basic data processing units, the 'chips', of the brain. Each neuron receives electrical inputs from about 1000 other neurons.
New research from Italy suggests that low levels of vitamin D may increase your risk of erectile dysfunction. When researchers tested 143 men with varying degrees of erectile dysfunction, they found that nearly half of them were coming up deficient in D, and only one in five had optimal levels of the nutrient.
Johns Hopkins researchers have discovered what could be the first conclusive evidence in men that the long-term effects of vitamin D deficiency are amplified by lower levels of the key sex hormone estrogen, but not testosterone.ichos recommends that men and women boost their vitamin D levels by eating diets rich in fatty fish, such as cod, sardines and mackerel, consuming fortified dairy products, taking vitamin supplements, and in warmer weather briefly exposing skin to the sun's vitamin-D producing ultraviolet light.
