Lecithin: a Very Special Substance - The egg yolk - carotenoids make them yellow like gold
"
Egg yolks are full of lecithin, a biologically valuable substance that every cell of the body needs. The more important an organ is, the more lecithin it contains. Bone marrow, brain, liver and heart are particularly rich in lecithin. Although lecithin is a fat, it is not used as a source of energy, but is responsible for vital tasks in the cell membranes, especially in nervous tissue.
Our bodies can produce the valuable substance themselves or obtain it from food. Lecithin doesn’t just aid memory and concentration; it also strengthens nerves,
positively influences cholesterol levels and hinders the formation of gallstones. "
