Eggs are foods that are full of the nutritional value. However, eggs are also often linked to various health problems. This is because eggs contain cholesterol, especially in the egg yolks. However, there are many other benefits derived from the yolk.
Here are some benefits of egg yolks that you can not find in the egg white
- More vitamin.
Egg yolks contain more vitamins both the type and number compared with the egg white. Each egg yolk contains seven vitamins, such as vitamin B6, B-12, A, D, E, K, and folate. Vitamin A, D, E and K are only found in egg yolks only, not in the egg whites.
- More minerals.
Such as vitamins, minerals are crucial micronutrients required by the body. Minerals are essential nutrients that are used to manage functions such as balancing the body's electrolytes. Egg yolks and egg whites have 13 types of minerals, including from calcium, magnesium, iron, potassium, sodium, and selenium. Although both parts are equally eggs contain minerals, but the yolk contains a lot more for each mineral. For
example, 90 percent of the calcium contained in the egg are in the
yolk; 93 percent iron content in eggs is in the yolk, and only 7 percent
is in the whites.
- Eye Health
Carotenoids in the egg yolk, particularly the carotenoids lutein and zeaxanthin, are very beneficial for eye health. According
to the researchers, these carotenoids, which is the pigment that gives
color to the yellow color of egg yolk, can lower the risk of age-related
degeneration and cataracts. This
substance acts as an antioxidant for the eyes, fight free radicals that
can damage parts of the retina that can affect the eye's ability to
focus.
- Benefits of choline
Egg yolks with vitamins, minerals, and other nutrients in it, it also helps to improve heart and cardiovascular health. Not
only the consumption of moderate amounts of eggs that showed benefits
for the heart, but also nutrients in the yolk, which is choline, helps
to regulate cardiovascular function.
In
addition, a study at the University of North Carolina at Chapel Hill
found that women who ate foods with high levels of choline have 24
percent less likely to have breast cancer than those who do not.
Eating a variety of foods every day, not just increase your appetite but also affect the quality of sleep.Eating foods with the same pattern, although these nutritious foods will lead to boredom.
For
example, just because a diet or fear of health risks every morning you
eat a bowl of oatmeal with fruit pieces, sauteed veggies to eat lunch,
and dinner only mengasup vegetables without rice.Repeating
pattern, according to a study conducted by a team from the University
of Pennyslvania, will affect the quality of sleep at night.
Conclusions
are generated after they analyzed data collected by the Center for
Disease Control and Prevention by the number of respondents of thousands
of people.By
comparing each individual's daily diet and sleep patterns, the
researchers outline the specific link between food variety and quality
of sleep.
"There
are many people associate between the diet and the quality of sleep but
scientific data on the subject is very minimal," said Michael Grandner,
from the center of the study of sleep and circadian neurobiology
University of Pennyslvania.
Grander discovered, the more varied the food consumed by the better quality of sleep a person. Those
who usually sleep less soundly is a diet lacking in carbohydrates and
protein, and other nutrients such as iron, zinc, and other minerals.
Corroborate the results of previous research, Grander said the people who sleep less soundly usually consume more calories. Experts suspect it is due to disturbance of hormonal balance as well since it is difficult to resist the urge to snack.
"Sleeping
and eating habits have a lot more similarities than we thought. Both
touching every system in the body and the body relies on both to work.
So if sleep and eating patterns are interrelated is not really
surprising, but how they are related may not have known , "Grander said.
How diet and sleep patterns affect each other is still a mystery. Good quality sleep is known to trigger us to eat nutritious food or nutritious food that will help us sleep soundly.
The initial studies so far has found that a deficiency in iron, calcium, and magnesium can make it hard to sleep soundly.
