Triglycerides are the most common form of fat found in our bodies. The word triglyceride describes this fat's chemical structure. Its chemical backbone is made up of glyceride (a carbon, oxygen, and hydrogen molecule) with three (tri) attached fatty acid chains. It is also the most common form of fat in vegetable oil and animal fat. Triglycerides are very important as they serve as one of our main energy reserves. They have more than twice the energy as an equivalent amount of carbohydrate or protein. Triglycerides can be absorbed from food through the intestine. Fat cannot freely circulate in the blood, and when we absorb triglycerides or fatty-acids in food, they are repackaged as triglycerides in a fat-protein transporter called a chylomicron. Our body can also make its own triglycerides when we eat more energy than we use, and the energy consumed does not necessarily have to come from fat. The liver can create a fat-protein ...

The experience of nerve pain is described with a variety of terms: burning, hot poker, itching, tingling, lightening, shooting, electrical, and so on. In medical terms, words like hyperalgesia and allodynia are used. Hyperalgesia means that an area is overly sensitive to painful (noxious) stimuli like a pinprick. Allodynia means that an area is overly sensitive to normally non-painful (non-noxious) stimuli like light touch. Both of these phenomena are hallmarks for nerve pain.
Many common ailments cause nerve pain. The most recognizable cause of nerve pain is diabetic peripheral neuropathy. The nerve damage caused by abnormal blood sugar levels cause the nerve to dieback in a "stocking and glove" distribution. First, the area of the foot and ankle region (stocking area) is usually affected with numbness and tingling. As the neuropathy progresses, burning pain will begin as well. Diabetic peripheral neuropathy is a classic example of nerve pain that is generated in the peripher...
