For decades, eggs were unfairly painted as heart villains, with nutrition experts warning us to keep them off our breakfast plates. The logic? Eggs are packed with cholesterol, and cholesterol was thought to be the key culprit behind clogged arteries and heart disease. But fresh science is scrambling those old beliefs.
In what’s being called a world-first, researchers at the University of South Australia recently put the egg-cholesterol connection under the microscope. Led by Professor Jon Buckley, the team recruited over 50 people for a tightly controlled diet study. Participants ate two eggs daily, but here’s the twist: their saturated fat intake remained low throughout the experiment.
The results upend much of what we’ve heard about eggs. The researchers found that when people kept their saturated fat intake down, eating eggs—even with their higher cholesterol content—had little to no effect on LDL (“bad”) cholesterol levels. In fact, some participants saw their LDL drop, hinting at a potential reduction in heart disease risk. “Eggs have long been unfairly cracked by outdated dietary advice,” said Buckley. “They’re unique—high in cholesterol, yes, but low in saturated fat. Our study shows that cholesterol from eggs isn’t the villain it’s been made out to be.”
This isn’t just one isolated finding either. Numerous studies now echo these results, showing that eggs can actually have a beneficial impact on cholesterol profiles when paired with healthy eating habits. Nutritionist Helen Bell of the UK Care Guide chimed in too, saying that eggs are also helpful for weight loss because their high protein content keeps you feeling full longer.
So what really raises LDL cholesterol? According to this latest research and many others, it’s not dietary cholesterol from foods like eggs—it’s saturated fat that deserves more scrutiny. And saturated fat is lurking in plenty of other foods: think processed meats and fatty dairy products.
In summary: If you enjoy eggs—and keep your overall saturated fat intake low—there’s little reason to toss them out of your diet. Instead, they might just be a heart-healthy choice after all.
