Calcium is water soluble, but not fat soluble. It is the fifth most dissolved ion in seawater. On the other hand, fat is soluble into calcium in the body. The calcium will exâ¦tract the fat from food in the digestive system, and they combine to form a foamy substance which is not absorbed by the body, and so the fat will be flushed out.
Studies show that it is about 20 percent of the resting metabolic rate, which is about 1,300 calories a day, not of the total metabolic rate, which is about 2,200 calories a day, so the brain uses roughly 300 calories.
Processes that lead to the death of neurons. The brain loses about 10000 neurons a day and if you have a bad diet, alcohol or other drugs are abused, the number is much higher. In drunkenness can lose up to 1000000 neurons. Stress prevents the new formation of neurons and even kills them. Hypertension can lead to the death of neurons.
