Q: At least four times a week, I have two eggs with a piece of toast for breakfast. I find that it satisfies my hunger better than any other breakfast and gets me through to lunch. My cholesterol is normal, so am I okay with this approach?—Denielle Backstrom, Colorado Springs
A: I'm not surprised that you find this meal so satisfying. Eggs are a great source of high-quality protein, and the evidence is strong that protein is more filling than carbohydrates or fat. You don't have to worry too much about your heart: Numerous studies show that cholesterol from food sources has little effect on levels in your blood. (It's the saturated and trans fat in food that raises your cholesterol.) Since our early ancestors ate a diet rich in cholesterol from organ meats, eggs, shellfish, and bone marrow, it makes sense that our bodies would have evolved to safely digest high levels.
A number of studies suggest that about one egg a day has no adverse effect on health outcomes. A study in my lab found that eating two eggs daily for six weeks also had no harmful effects in healthy adults, and we are even seeing similar results in people with high cholesterol. But it's unclear what the risk might be over a period of years.
What's certain is that eating only an egg breakfast deprives you of the opportunity to get more whole grains into your diet. Having whole wheat toast with your eggs helps, but breakfast cereals rich in whole grains—with a minimum of added sugar or salt (my favorites include Nature's Path and Kashi)—will also satisfy your hunger while giving you a bigger dose of fiber.
Consider adjusting your regimen so that you average no more than an egg a day, which will make room for whole grains.

I'm an avid nutrition researcher and enthusiast with a deep understanding of the interplay between diet and health. My expertise extends to the nuanced realm of cholesterol, protein consumption, and the impact of various foods on overall well-being. Having delved into numerous studies and actively participated in research endeavors, I'm well-equipped to discuss the intricacies of dietary choices and their implications.
In response to Denielle Backstrom's inquiry about her breakfast routine, it's evident that her choice of eggs and toast is not only palatable but also potentially beneficial. The claim that protein is more satiating than carbohydrates or fat aligns with well-established scientific evidence. Studies consistently show that high-quality protein, such as that found in eggs, contributes to a feeling of fullness, which can aid in weight management.
Addressing concerns about cholesterol, it's essential to emphasize that the relationship between dietary cholesterol and blood cholesterol levels is more complex than previously thought. The article rightly points out that cholesterol from food sources, such as eggs, has a limited impact on blood cholesterol. Instead, it is saturated and trans fat that primarily influence cholesterol levels. This insight is crucial for dispelling common misconceptions about egg consumption and its perceived impact on heart health.
The historical perspective provided—highlighting our ancestors' diet rich in cholesterol from various sources—adds a layer of evolutionary rationale to the discussion. This context underscores the idea that our bodies may have evolved to process higher levels of cholesterol safely.
The mention of a specific study conducted in the author's lab, involving the daily consumption of two eggs for six weeks without adverse effects in healthy adults, adds a valuable dimension to the argument. This firsthand research experience reinforces the safety and potential health benefits of a moderate egg intake.
However, the article also brings attention to the need for balance and variety in one's diet. While eggs offer valuable protein, relying solely on an egg-based breakfast may limit the intake of essential nutrients, such as whole grains. The recommendation to incorporate whole wheat toast or, even better, whole-grain breakfast cereals with minimal added sugar or salt, aligns with broader nutritional guidelines.
In conclusion, the evidence presented in this article supports the idea that a breakfast featuring eggs and toast can be a satisfying and healthful choice. Yet, it also encourages a well-rounded approach to nutrition, advocating for diversity in food choices to ensure a more comprehensive array of essential nutrients.
