Eggs Feed The Brain

Eggs are a good source of low-cost high-quality protein, providing 5.5 grams of protein (11.1% of the daily value for protein) in one egg for a caloric cost of only 68 calories. The structure of humans and animals is built on protein. We rely on animal and vegetable protein for our supply of amino acids, and then our bodies rearrange the nitrogen to create the pattern of amino acids we require. Another health benefit of eggs is their contribution to the diet as a source of choline. Although our bodies can produce some choline, we cannot make enough to make up for an inadequate supply in our diets, and choline deficiency can also cause deficiency of another B vitamin critically important for health, folic acid. Choline is a key component of many fat-containing structures in cell membranes, whose flexibility and integrity depend on adequate supplies of choline. Two fat-like molecules in the brain, phosphatidylcholine and sphingomyelin, account for an unusually high percentage of the brain's total mass, so choline is particularly important for brain function. In addition, choline is a highly important molecule in a cellular process called methylation. Many important chemical events in the body are made possible by methylation, in which methyl groups are transferred from one place to another. For example, genes in the body can be switched on or turned off in this way, and cells use methylation to send messages back and forth. Choline, which contains three methyl groups, is highly active in this process. Choline is also a key component of acetylcholine. A neurotrasmitter that carries messages from and to nerves, acetylcholine is the body's primary chemical means of sending messages between nerves and muscles.

  1. Thank you for this information. I am happy to hear that I did well when I ignored the psychologic terrorism on eggs being diffused in the late 70-ties and early 80-ties because of their high content of cholesterol.

    For the brain in the 70-ties there was a famous product containing lecithin. But lecithin is as well provided by the yellow of the egg.

    And eggs are not only healthy, but tasting well.

    Isn't Gallus gallus a wonderful bird?



    "For example, genes in the body can be switched on or turned off in this way..."

    This is an interesting point of view also for the environment vs genetics debate.


    Happy Easter to everyone!!!

  3. One of the most widely held food and holiday associations is that of the Easter egg. How the egg became associated with this holiday seems to have roots that are both biological and cultural. Before more modern techniques of poultry raising, hens laid few eggs during the winter. This meant that Easter, occuring with the advent of spring, coincided with the hen's renewed cycle of laying numerous eggs. Additionally, since eggs were traditionally considered a food of luxury, they were forbidden during Lent, so Christians had to wait until Easter to eat them-another reason eggs became associated with this holiday. Interestingly enough, the custom of painting eggshells has an extensive history and was a popular custom among many ancient civilizations, including the Egyptians, Chinese, Greeks and Persians.
