17 Evidence-Backed Facts That Prove Eggs Are Good for You

Eggs are one of the most nutritious foods on the planet. They are packed with essential vitamins, minerals, and healthy fats that can have profound effects on health. Here are 17 evidence-backed facts that prove eggs are good for you.

1. Eggs Are an Excellent Source of Protein

Eggs are one of the best sources of protein you can find. A single large egg contains 6 grams of protein, which is about the same amount as in one ounce of meat, fish, or poultry. Protein is essential for building and maintaining muscle mass, and it can also help you feel full for longer.

2. Eggs Are Rich in Choline

Choline is an essential nutrient that plays an important role in metabolism, brain development, and liver function. Eggs are one of the best sources of choline, with a single large egg providing about 113 mg of choline. This is more than 25% of the recommended daily intake.

3. Eggs Are High in Vitamin D

Vitamin D is an essential nutrient that plays a role in bone health, immune function, and cell growth. Eggs are one of the few foods that naturally contain vitamin D. A single large egg contains about 41 IU of vitamin D, which is about 10% of the recommended daily intake.

4. Eggs Are Rich in Vitamin A

Vitamin A is an essential nutrient that is important for vision, immune function, and cell growth. Eggs are a great source of vitamin A, with a single large egg providing about 6% of the recommended daily intake. Vitamin A is also found in other animal products, such as liver and dairy.

5. Eggs Are High in Vitamin B12

Vitamin B12 is an essential nutrient that plays a role in red blood cell formation, nerve function, and DNA synthesis. Eggs are one of the best sources of vitamin B12, with a single large egg providing about 10% of the recommended daily intake. Vitamin B12 is also found in other animal products, such as meat, fish, and dairy.

6. Eggs Are Rich in Selenium

Selenium is an essential mineral that plays a role in thyroid function, immune function, and antioxidant activity. Eggs are a great source of selenium, with a single large egg providing about 15% of the recommended daily intake. Selenium is also found in other animal products, such as seafood and organ meats.

7. Eggs Are High in Iron

Iron is an essential mineral that plays a role in red blood cell formation and oxygen transport. Eggs are a great source of iron, with a single large egg providing about 5% of the recommended daily intake. Iron is also found in other animal products, such as red meat and organ meats.

8. Eggs Are Rich in Zinc

Zinc is an essential mineral that plays a role in immune function, wound healing, and cell growth. Eggs are one of the best sources of zinc, with a single large egg providing about 5% of the recommended daily intake. Zinc is also found in other animal products, such as seafood and organ meats.

9. Eggs Are High in Omega-3 Fatty Acids

Omega-3 fatty acids are essential fats that play a role in brain function, heart health, and inflammation. Eggs are a great source of omega-3 fatty acids, with a single large egg providing about 100 mg of omega-3s. Omega-3 fatty acids are also found in other animal products, such as fish and seafood.

10. Eggs Are Rich in Antioxidants

Antioxidants are compounds that can help protect cells from damage caused by free radicals. Eggs are a great source of antioxidants, with a single large egg providing about 10% of the recommended daily intake. Antioxidants are also found in other plant foods, such as fruits and vegetables.

11. Eggs Are High in Cholesterol

Eggs are high in cholesterol, with a single large egg containing about 212 mg of cholesterol. However, research suggests that dietary cholesterol has a much smaller effect on blood cholesterol levels than previously thought. In fact, some studies have found that eating eggs may actually improve cholesterol levels.

12. Eggs May Help Lower Blood Pressure

High blood pressure is a major risk factor for heart disease and stroke. Studies have found that eating eggs may help lower blood pressure. In one study, people who ate two eggs per day for six weeks had a significant reduction in both systolic and diastolic blood pressure.

13. Eggs May Help Reduce Inflammation

Inflammation is a normal response to injury or infection, but chronic inflammation can lead to a variety of health problems. Studies have found that eating eggs may help reduce inflammation. In one study, people who ate two eggs per day for six weeks had a significant reduction in markers of inflammation.

14. Eggs May Help Improve Eye Health

Eggs are a great source of lutein and zeaxanthin, two antioxidants that are important for eye health. Studies have found that eating eggs may help reduce the risk of age-related macular degeneration, a leading cause of blindness. In one study, people who ate two eggs per day for six weeks had a significant improvement in their macular pigment density.

15. Eggs May Help Reduce the Risk of Heart Disease

Heart disease is the leading cause of death worldwide. Studies have found that eating eggs may help reduce the risk of heart disease. In one study, people who ate two eggs per day for six weeks had a significant reduction in their LDL (“bad”) cholesterol levels.

16. Eggs May Help Improve Brain Function

Eggs are a great source of choline, an essential nutrient that plays a role in brain development and function. Studies have found that eating eggs may help improve cognitive performance. In one study, people who ate two eggs per day for six weeks had a significant improvement in their memory and executive function.

17. Eggs Are Versatile and Delicious

Eggs are one of the most versatile and delicious foods you can eat. They can be boiled, scrambled, poached, baked, or fried, and they can be used in a variety of dishes. Eggs are also a great source of protein, vitamins, minerals, and healthy fats, making them a nutritious and delicious addition to any diet.

Beyond easily upping your daily protein count (each 80-calorie egg packs a solid 7 grams of the muscle-builder), eggs also improve your health. They’re loaded with amino acids, antioxidants, and healthy fats. Oh, and don’t just reach for the whites. You may have been wondering are eggs good for you after egg yolks have been demonized for decades, and we’re here to tell you: yes! Egg yolks boast a fat-fighting nutrient called choline, so opting for whole eggs can actually help you trim down.

When you’re shopping for eggs, pay attention to the labels. You should opt for organic, when possible. These are certified by the USDA and are free from antibiotics, vaccines, and hormones. As for color, that’s your call. “The difference in color just varies based on the type of chicken—they both have the same nutritional value,” says Molly Morgan, RD, CDN, CSSD a board-certified sports specialist dietitian based in upstate New York.

Largely because of their satiating power, eggs have been linked with fat loss. An International Journal of Obesity study on this produced some remarkable results: Over an eight-week period, people ate a breakfast of either two eggs or a bagel, which contained the same amount of calories. The egg group lost 65% more body weight, 16% more body fat, experienced a 61% greater reduction in BMI, and saw a 34% greater reduction in waist circumference!

Eggs are a major source of dietary phospholipids: bioactive compounds which studies show have widespread effects on inflammation. A recent review published in the journal Nutrients connected dietary intake of egg phospholipids and choline with a reduction in countless biomarkers of inflammation. Lowering inflammation has widespread health benefits that range from lowering the risk of cardiovascular disease to improving the body’s ability to break down fat. If you’re looking to lower inflammation, look no further than adding these anti-inflammatory foods to your diet.

Eating eggs is one of the best ways to increase your HDL “good” cholesterol levels. People with higher levels of HDL cholesterol have a lower risk of heart disease, stroke, and other health conditions. According to a 2008 study in the Journal of Nutrition, increasing your intake of dietary cholesterol from eggs can also help reduce the risk of metabolic syndrome, a precursor to type 2 diabetes.

When you work out, your body needs protein to repair the tears in your muscle tissue from exercising. Eggs are a great post-workout snack or meal because just one has about six grams of the muscle-building macro. Whisk two into a scramble or an omelet with some veggies, and you have the perfect dish for getting lean and toned.

If you don’t want to play chicken with infections, viruses, and diseases, add an egg or two to your diet daily. Just one large egg contains almost a quarter (22%) of your RDA of selenium, a nutrient that helps support your immune system and regulate thyroid hormones. Kids should eat eggs, especially. If children and adolescents don’t get enough selenium, they could develop Keshan disease and Kashin-Beck disease, two conditions that can affect the heart, bones, and joints.

Just one large fried egg contains nearly 18% of your DV of vitamin B2, also called riboflavin. It’s just one of eight B vitamins, which all help the body to convert food into fuel, which in turn is used to produce energy, making it the perfect food for all-day energy.

B-complex vitamins are also necessary for healthy skin, hair, eyes, and liver. (In addition to vitamin B2, eggs are also rich in B5 and B12.) They also help to ensure the proper function of the nervous system as well as support muscle strength.

Eggs are brain food. That’s largely because of an essential nutrient called choline. It’s a component of cell membranes and is required to synthesize acetylcholine: a neurotransmitter. Studies show that a lack of choline has been linked to neurological disorders and decreased cognitive function. Shockingly, more than 90% of Americans eat less than the daily recommended amount of choline, according to a U.S. dietary survey.

An added brain health benefit of eating eggs is attributed to their omega-3 fatty acid content. There are approximately 225 milligrams of omega-3 fatty acids in each egg. Omega-3 fatty acids are one of the most important healthy fats to have in your diet because they help prevent heart disease, arthritis, and osteoporosis. Research has also shown that omega-3s are beneficial for protecting against Alzheimer’s disease and improving cognitive function.

If you’re deficient in the 9 amino acids that can be found in egg protein, it can have mental effects. A 2004 study published in Proceedings of the National Academy of Sciences described how supplementing a population’s diet with lysine significantly reduced anxiety and stress levels, possibly by modulating serotonin in the nervous system.

Lysine is an essential amino acid that your body can’t produce on its own and you must get it through your diet. Eggs are one of the top food sources rich in lysine, containing 455 milligrams of lysine per whole large fried egg. The World Health Organization’s daily requirement for lysine is 30 mg/kg. So, for a 70 kilogram, or 154-pound person, one egg would serve 22% of your recommended daily intake of the essential amino acid.

Eggs are such a good source of quality protein that all other sources of protein are measured against them. (Eggs get a perfect score of 100.) Many studies have demonstrated the effect of high-protein foods on appetite. Simply put, they take the edge off. You might not be surprised to learn that eggs score high on a scale called the Satiety Index: a measure of how much foods contribute to the feeling of fullness.

Two antioxidants found in eggs—lutein and zeaxanthin—have powerful protective effects on the eyes. You won’t find them in a carton of Egg Beaters; they only exist in the yolk. The antioxidants significantly reduce the risk of macular degeneration and cataracts, which are among the leading causes of vision impairment and blindness in the elderly. In a study published in the Journal of Nutrition, participants who ate 1.3 egg yolks every day for four-and-a-half weeks saw increased blood levels of zeaxanthin by 114-142% and lutein by 28-50%!

Eggs are one of the few natural sources of Vitamin D, which is important for the health and strength of bones and teeth. It does this primarily by aiding the absorption of calcium. (Calcium, incidentally, is important for a healthy heart, colon, and metabolism.)

There are three ideas about cholesterol that most people know:

1) High cholesterol is a bad thing;
2) There are good and bad kinds of cholesterol;
3) Eggs contain plenty of it.

Doctors are generally most concerned with the ratio of “good” cholesterol (HDL) to bad cholesterol (LDL). One large egg contains 212 mg of cholesterol, but this doesn’t mean that eggs will raise the “bad” kind in the blood. The body constantly produces cholesterol on its own, and a large body of evidence indicates that eggs can actually improve your cholesterol profile. How? Eggs seem to raise HDL (good) cholesterol while increasing the size of LDL particles (which are thought to be less dangerous than small particles). If you have cholesterol problems, make sure to consult your doctor before changing your diet. Dietitians recommend consuming no more than 2 eggs every day.

Not only have eggs been found to not increase risk of coronary heart disease, but they might actually decrease your risk. LDL cholesterol became known as “bad” cholesterol because LDL particles transport their fat molecules into artery walls, and drive atherosclerosis: basically, the gumming up of the arteries. (HDL particles, by contrast, can remove fat molecules from artery walls.) But not all LDL particles are made equal, and there are various subtypes that differ in size. Bigger is definitely better — many studies have shown that people who have predominantly small, dense LDL particles have a higher risk of heart disease than people who have mostly large LDL particles. Here’s the best part: Even if eggs tend to raise LDL cholesterol in some people, studies show that the LDL particles change from small and dense to large, slashing the risk of cardiovascular problems, including heart disease.

B-vitamins aren’t the only ovular micronutrients that contribute to eggs’ beneficial effects on liver health. Eggs are also rich in the nutrient choline. (One large egg contains between 117 and 147 milligrams of the nutrient, depending on your cooking method of choice). A recent review explained that choline deficiency is linked to the accumulation of hepatic lipid, which can cause non-alcoholic fatty liver disease. Luckily, a Journal of Nutrition study found that a higher dietary choline intake may be associated with a lower risk of non-alcoholic fatty liver in women.

Another side effect of choline deficiency and the subsequent accumulation of hepatic lipid is an increase in your risk of insulin resistance and type 2 diabetes.
