Are eggs good for you? Yes! Eggs are nutrient-dense, packed with protein, vitamins, and healthy fats. They support muscle growth, heart health, and brain function. Despite past concerns about cholesterol, studies show that eggs can be part of a healthy diet for most people.
Are Eggs Good for You? Let’s Break it Down
Eggs have been a dietary staple for centuries, but they’ve also been the subject of much debate. Some say they’re nature’s perfect food, while others worry about cholesterol and heart health. So, what’s the truth?
The reality is that eggs are packed with nutrition. They’re one of the most nutrient-dense foods you can eat, providing high-quality protein, essential vitamins, and healthy fats in a low-calorie package. But like any food, the context of how you consume them matters.
The Nutritional Power of Eggs
One of the biggest advantages of eggs is their impressive nutrient profile. A single large egg contains:
- High-Quality Protein: About 6 grams of complete protein, meaning it provides all nine essential amino acids your body can’t produce on its own.
- Healthy Fats: Roughly 5 grams of fat, most of which is unsaturated, supporting brain function and overall health.
- Vitamins and Minerals: Eggs are rich in vitamins A, D, E, B12, and riboflavin, as well as minerals like iron, selenium, and phosphorus.
- Choline: An essential nutrient for brain health and function.
Eggs are a nutritional powerhouse. The combination of protein and healthy fats makes them a satisfying food that keeps you full longer. This is why they’re often recommended for weight management, as they help prevent overeating later in the day.
Research Highlight:
A 2018 study in The American Journal of Clinical Nutrition found that including eggs in a calorie-controlled diet helped participants feel fuller for longer and contributed to improved weight management (Kim et al., 2018).

Myth: Eggs Are Bad for Your Heart
The biggest controversy around eggs has been their cholesterol content. One large egg contains about 186 mg of cholesterol, which led to concerns that eggs could increase the risk of heart disease. However, the latest research tells a different story.
For most people, dietary cholesterol has little impact on blood cholesterol levels. The body regulates cholesterol production, and the cholesterol you eat doesn’t necessarily translate to higher levels of “bad” LDL cholesterol in your blood.
Research Highlight:
A landmark study published in The BMJ followed over 400,000 participants and found no significant association between egg consumption and cardiovascular disease in most people (Drouin-Chartier et al., 2019). In fact, for some people, eating eggs was linked to improved heart health due to their nutrient content.

Eggs and Weight Management
Are eggs good for you if you’re trying to lose weight? Absolutely. Their high protein content helps promote fullness, reducing the likelihood of overeating. Including eggs in your breakfast can be particularly effective.
In one study, participants who ate eggs for breakfast felt fuller and consumed fewer calories throughout the day compared to those who ate a carbohydrate-rich breakfast like bagels. The protein in eggs helps to stabilise blood sugar levels and prevents spikes that lead to cravings.
Practical Tip:
For a balanced, satisfying breakfast, try scrambled eggs with vegetables and whole-grain toast. The combination of protein, fibre, and complex carbs will help keep you energised and full until your next meal.
The Role of Eggs in Brain Health
One of the less-discussed benefits of eggs is their positive impact on brain health. This is primarily due to the nutrient choline, which is found in abundance in egg yolks. Choline is essential for producing acetylcholine, a neurotransmitter that plays a key role in mood, memory, and cognitive function.
Research has also linked higher choline intake to a reduced risk of cognitive decline as we age. In fact, many people do not get enough choline in their diet, making eggs an excellent option to support long-term brain health.
Research Highlight:
A study in The Journal of the American College of Nutrition found that higher choline intake was associated with improved memory performance and cognitive function in older adults (Poly et al., 2011).

How to Include Eggs in a Balanced Diet
Eggs can easily be incorporated into a healthy diet, but how you prepare them makes a big difference. Boiled or poached eggs are excellent choices because they don’t require added fats. Scrambled eggs can also be healthy, especially if cooked in a small amount of olive oil rather than butter.
However, fried eggs, especially when prepared with a lot of butter or oil, can increase the calorie and fat content of your meal significantly. Likewise, pairing eggs with processed meats like bacon or sausage can offset their health benefits. Instead, try adding eggs to a salad, mixing them into vegetable stir-fries, or using them to make a nutritious frittata.
Are Eggs Safe for Everyone?
While eggs are good for most people, there are a few exceptions. Some individuals may have an egg allergy, particularly children, though many outgrow it. Additionally, people with diabetes may need to be cautious about eating too many eggs, as there’s some evidence that excessive egg consumption could increase the risk of heart disease in this group.
That said, for the majority of the population, eggs are a safe, nutrient-dense food that can be enjoyed regularly.
Mistake to Avoid: Skipping the Yolks
Many people mistakenly believe that egg whites are healthier than whole eggs, often throwing away the yolk to reduce fat and calorie intake. But the yolk is where most of the nutrients are! You miss out on vitamins A, D, E, and B12, along with healthy fats and choline, if you skip the yolk.
Egg whites are a good source of lean protein, but for maximum nutritional benefit, eat the whole egg. Studies have shown that the cholesterol in egg yolks doesn’t negatively impact heart health for most people, so there’s no need to fear it.
How Many Eggs Can You Eat a Day?
Current research suggests that for most healthy people, one to two eggs per day is perfectly safe and can even offer several health benefits. However, as with any food, moderation is key. Including a variety of protein sources in your diet ensures you get a broader range of nutrients.
If you have specific health conditions like diabetes or a family history of heart disease, it’s a good idea to talk to your doctor about how eggs can fit into your diet.
Conclusion: Yes, Eggs Are Good for You
In summary, eggs are one of the most nutritious foods available. They’re high in quality protein, packed with vitamins and minerals, and offer numerous health benefits, from supporting brain function to aiding weight management. Despite past concerns about cholesterol, research shows that eggs can be part of a healthy diet for most people.
