There are few foods more controversial than the incredible, edible egg. As real nutritional powerhouses, eggs are high in choline, which enhances brain function; the antioxidants lutein and zeaxanthin, which fight disease; and high-quality protein. There is even evidence that egg consumption may protect against breast cancer.
Yet eggs are also high in cholesterol, and for decades, doctors advised people to limit their egg consumption in order to prevent heart disease. But when research showed that dietary cholesterol impacts LDL (“bad”) blood cholesterol far less than previously thought, the American Heart Association changed its tune in 2000. Current guidelines now allow for one egg a day for healthy adults.
