Can eating eggs increase the risk of type 2 diabetes? Know what study reveals

Eggs are one of the simplest, most loved foods in the world, a breakfast favourite that can be boiled, scrambled, poached, or turned into fluffy omelettes. They are celebrated for being affordable, protein-packed, and loaded with vitamins. But in recent years, a big question has emerged: can eating eggs increase your risk of type 2 diabetes?

For many people, eggs are considered a “superfood,” while for others, they’re a red flag due to their cholesterol content. The debate has grown louder with new research suggesting a link between frequent egg consumption and a higher risk of type 2 diabetes, at least in certain populations.

A major study published in the American Journal of Medicine (2022) analysed evidence from over 400,000 people worldwide. The results were eye-opening: those who ate eggs daily were more likely to develop type 2 diabetes compared to people who ate them sparingly. But here’s the twist: the risk varied depending on where people lived and what their overall diet looked like.



Egg consumption and diabetes risk: What the research found

The study pulled together data from 16 large cohort studies, making it one of the most comprehensive analyses on this topic. Researchers discovered that:

• Eating one or more eggs per day was linked to a 7% to 15% higher risk of type 2 diabetes.
• The effect was strongest in Western countries, where eggs are often consumed with bacon, sausages, buttered toast, and refined carbs.
• In Asian countries, egg consumption didn’t show a strong connection to diabetes risk, possibly because eggs are often eaten with vegetables, rice, or balanced meals.

This shows that the risk isn’t just about eggs themselves, but about the company they keep on your plate.



Why eggs may influence diabetes risk

Several factors could explain why eggs sometimes appear risky in studies:

• Cholesterol content: One large egg contains about 186 mg of cholesterol, which may affect insulin sensitivity in some individuals when consumed in excess.
• Cooking methods: Fried eggs with oil, butter, or cheese can add extra saturated fats, which may worsen blood sugar control.
• Dietary context: In Western diets, eggs often come with processed meats and refined carbs, both known to increase diabetes risk.
• Individual differences: Genetics, physical activity, and overall lifestyle may determine whether eggs have a neutral or harmful effect.

Should you stop eating eggs completely?

The short answer: No, eggs are not bad for you. In fact, they remain one of the most nutrient-dense foods you can include in your diet. Eggs are a rich source of high-quality protein, vitamin B12, choline (essential for brain health), and healthy fats. For most healthy individuals, eating 3 to 6 eggs per week is considered not only safe but also beneficial. When eggs are paired with fibre-rich foods, such as vegetables, whole grains, or legumes, the nutritional value of the meal improves even further, supporting heart health and digestion.

What matters more than the number of eggs you eat is how you prepare and pair them. Instead of frying eggs in butter or oil, opt for healthier cooking methods like boiling, poaching, or dry-scrambling. Also, be mindful of what you eat with your eggs; try to avoid processed meats like bacon or sausage, which are high in sodium and saturated fats. Balance is key. If you keep your overall intake of cholesterol, saturated fats, and calories in check, eggs can be a valuable and delicious part of a well-rounded, healthy diet.



Experts' recommendations on eating eggs


Dietitians stress that context is everything. As Dr. Ming Li, co-author of the 2022 study, explained, “Eggs can be part of a healthy diet, but we need to consider the broader dietary patterns in which they are consumed.”

In India, where eggs are often eaten with curries, vegetables, or rotis, the risk may be lower compared to the Western habit of eggs-and-bacon breakfasts. However, people with a family history of diabetes should be mindful of portion sizes.



Practical tips for egg lovers with diabetes risk

• Stick to 3–4 eggs per week if you have prediabetes or are concerned about blood sugar.
• Add fibre, like spinach, tomatoes, or whole wheat bread, to your egg meals to slow sugar spikes.
• Limit fried eggs and cheese-loaded omelettes; go for boiled or poached.
• Focus on a balanced plate rather than obsessing over one food.

Eggs are not the enemy, but neither are they a free pass to unlimited consumption. The latest evidence suggests that while eggs offer valuable nutrients, daily high consumption may raise the risk of type 2 diabetes, especially in Western-style diets.

If you love eggs, enjoy them in moderation, cook them in healthier ways, and pair them with wholesome foods. Ultimately, it’s not just about the egg on your plate, but the diet and lifestyle that surround it.
