The Incredible Health Benefits of Eggs
Besides being an
incredibly versatile ingredient that can be used in most dishes - savory or
sweet - eggs are exceptionally nutritious. Their goodness can be found in the
yolk, which contains over 90 percent of an egg's calcium and iron, while the
white part contains almost half of the egg's protein.
So, if you're not
eating eggs regularly, here are 10 reasons you ought to.
1.
They are among the most nutritious food on the planet.
Eggs contain a little bit of almost
every nutrient we need, making them the perfect food. In fact, a single boiled
egg contains:
• Vitamin A (6% of the RDA*)
• Folate (5% of the RDA)
• Vitamin B5 (7% of the RDA)
• Vitamin B12 (9% of the RDA)
• Vitamin B2 (15% of the RDA)
• Phosphorus (9% of the RDA)
• Selenium (22% of the RDA)
• Eggs also contain decent amounts of vitamin D, vitamin E, vitamin K, vitamin B6, calcium and zinc.
• Folate (5% of the RDA)
• Vitamin B5 (7% of the RDA)
• Vitamin B12 (9% of the RDA)
• Vitamin B2 (15% of the RDA)
• Phosphorus (9% of the RDA)
• Selenium (22% of the RDA)
• Eggs also contain decent amounts of vitamin D, vitamin E, vitamin K, vitamin B6, calcium and zinc.
In total, eggs equate to 77
calories, 6 grams of protein and 5 grams of healthy fats.

2.
While eggs may be high in cholesterol, they don't adversely affect blood
cholesterol.
True, eggs are high in cholesterol.
In fact, a single egg contains 212mg, which is over half of the recommended
daily intake of 300mg. However, while it may seem counter-productive to eat
eggs, the cholesterol in eggs does not necessarily raise cholesterol in the
blood. Of course, it is important to note that the response of egg consumption
varies from one individual to another. But overall, studies have shown that in
70 percent of people, eggs did not raise cholesterol at all. However, in the
other 30 percent (termed hyper responders) eggs mildly raised total and LDL
cholesterol.
3.
For the most part, eggs actually raise HDL (healthy) cholesterol.
Often termed the good cholesterol,
consuming eggs are a great way to increase HDL. In one study, it was found that
those who consumed two eggs per day for six weeks, saw their HDL increased by
10 percent. It has also been shown that people with higher levels of HDL,
usually have a lower risk of heart disease, stroke, and various health
problems.
4.
Eggs contain choline - an important nutrient that most people do not get enough
of.
This important nutrient is grouped
within the B vitamins. It is used to build cell membranes and plays a
role in the production of signaling molecules in the brain. However,
according to dietary surveys, 90 percent of the U.S population is getting less
than they ought to. Whole eggs are therefore an excellent source of choline, as
a single egg contains more than 100mg.
5. Eggs convert LDL cholesterol particles from small and dense to large.
This change in particles has been
linked to a reduced risk of heart disease.
It is a well-known fact that having
high levels of LDL (bad cholesterol) is linked to an increased risk of heart
disease. However, what is not well known is that there are subtypes of LDL.
See, there are small, dense LDL particles, and there are also large LDL particles.
Studies have shown that people who predominantly have small, dense LDL
particles also have a higher risk of heart disease than those with large LDL
particles.
So, as I pointed out in the third
fact, while eggs may mildly raise LDL cholesterol in some individuals, studies
have shown that eggs may potentially change LDL particles from small and dense
to large.
Aging usually brings with it the
onset of poorer eyesight. Thankfully though, several nutrients can help
counteract some of the degenerative processes which can affect our eyes. Lutein
and zeaxanthin are two such powerful antioxidants which tend to build up in the
retina of the eye. In a controlled trial, it was found that eating 1.3 egg
yolks per day for 4.5 weeks increases blood levels of lutein (by 28 to 50
percent) and zeaxanthin (by 114-142 percent).
Furthermore, studies have shown that consuming adequate amounts of these nutrients can significantly reduce the risk of cataracts and macular degeneration - two very common eye disorders. Eggs also contain substantial amounts of vitamin A, which can reduce blindness.
7.
Eggs rich in Omega-3, lower triglycerides (a risk factor for heart disease).
Not all eggs are created equal.
Their nutrient composition varies depending on what the hens were fed and how
they were raised. Hens that were raised on pasture and/or fed Omega-3 enriched
foods tend to lay eggs that have a much higher Omega-3 fatty acids content
- a nutrient that is known to reduce blood levels of triglycerides (a risk
factor for heart disease).
8.
Eggs are a great source of protein - the main building blocks of the human
body.
Ensuring that you get enough protein
in your diet is important - in fact, it has been suggested that the Recommended
Daily Amounts (RDAs) may be too low. But, seeing that eggs contain all the
essential amino acids in the right ratios, our bodies are easily able to absorb
the protein found in eggs. Eating adequate amounts of protein may also help
with weight loss, increasing muscle mass, lowering blood pressure and
optimizing bone health. One single, large egg contains 6 grams of protein.
9.
Eggs may actually reduce the risk of a stroke.
Eggs have been unfairly demonized
for decades, due to the levels of cholesterol found in them. However, many
studies have examined the relationship between egg consumption and the risk of
heart disease. In one meta-review of 17 studies, with a total of 263,938
participants, no association was found between egg consumption and heart
disease or stroke.
However, some studies have found that people with diabetes who ate eggs can have an increased risk of heart disease. Nevertheless, whether the eggs are actually causing the increased risk is not known.
10.
Eggs score high on the Satiety Index, inducing feelings of fullness and
reducing subsequent calorie intake.
Eggs are high in protein, which is
one of the most fulfilling macronutrients. In one study of 30 overweight women,
it was found that eating eggs instead of bagels for breakfast, increased
feelings of fullness, making them automatically eat fewer calories during the
following 36 hours. It was also found that eating an egg for
breakfast caused significant weight loss over a period of 8 weeks.
