Below are some of the health benefits of egg:
Good Source of Choline
Choline is an important nutrient that is present in some food and usable as dietary supplement. It’s a good source of Methyl groups used for many steps in metabolism. Choline has a macronutrient with physiological functions such as, nerve function, neurological development, metabolism and muscle control.
Since eggs are rich dietary source of choline, one medium egg contains about 100mg of choline. Basically, there is no guideline for the intake of Choline, but it is advisable for women who are not pregnant or nursing mothers to take about 425-500mg of choline daily. While adult men can take 550mg on a daily basis. Eating of one egg on a daily basis can help you on this goal.
Help in preventing Cardiovascular disease
Egg contains about 25% of recommended dietary allowance (RDA) of selenium making it one of the good dietary sources of mineral. Selenium is a strong anti-inflammatory that is directly connected with some issues of cardiovascular disease which can cause deficiency in mineral. This can help in decreasing death rate caused by cardiovascular diseases.
Egg Contains Amino Acid That Is Perfect for Protein.
Egg is considered as a good source of protein. Amino acid is considered as the building block of protein and the quality of protein is determine by three criteria which are; amino acid bioavailability, digestibility and amino acid composition.
Basically, there are twenty one of these amino acids, nine of which the body is unable to create on its own and must get it from dietary source. For the assessment of protein to be high, food is expected to be high in the nine aminos that your body cannot produce. But with the help of egg, the nine amino acid can be produce.
