A certified nutrition expert explains that combining eggs with healthy fats like olive oil, avocados, or nuts may enhance the body's ability to absorb vitamin D, as it is a nutrient that dissolves in fat. Eggs are one of the limited foods that inherently provide vitamin D, and methods of cooking such as boiling, scrambling, or frying do not largely diminish their vitamin D levels. Additionally, specialists emphasize that regularly incorporating vitamin D-rich foods into one’s daily diet is more beneficial for overall intake than concentrating on a single meal.
