For example, some ingredients may be safe in products such as cleansers that we wash off the skin immediately, but not in products that we leave on the skin for hours. Similarly, ingredients that are safe for use on the hair or nails may be unsafe when used on the skin or near the eyes.
Carbohydrates are the main energy source for the brain. Without carbohydrates, the body could not function properly. Sources include fruits, breads and grains, starchy vegetables and sugars. Make at least half of the grains you consume whole grains.
Sugars and fats are among some of the most important nutrients that can be broken down by the cells and utilized for energy purposes. Certain types of proteins that exist on the surface of the membrane of the cell allow these types of materials to enter the cell. Cells then break these food particles down through a series of oxidation processes. This allows for the transfer of electrons into the cell. The electrons from the food are taken in by the cell. Once this has been done, the cell can convert the energy into small molecules with lots of energy, such as nicotinamide adenine dinucleotide.
