Eggs have always divided experts and consumers: there are those who consider them a food to be consumed in moderation and those who, however, have reevaluated them in light of the most recent scientific evidence, which suggests that limiting them is no longer as necessary as once thought. In short, their reputation has gone through ups and downs over the years and even today the judgment is not definitive.
The American dietitian Lauren Manaker decided to do a small experiment, testing herself what it means to integrate an egg a day into one’s diet, documenting the experience for seven consecutive days.
The objective of the experiment was clear: to test whether consuming an egg every day could actually influence well-being, energy and appetite management. Manaker varied the preparations – from boiled egg to poached egg, from the scrambled version to the most creative recipes – to avoid monotony and test different cooking methods.
A first “surprise” emerged almost immediately: since she was carefully tracking the total intake, the dietician realized how omnipresent this ingredient is in our diet. Egg pasta, baked goods, breading and various preparations have caused consumption to skyrocket well beyond the planned single egg.
The changes perceived day after day
The first positive effect recorded by Manaker concerns energy management throughout the day. No more mid-morning or afternoon crashes, energy levels remained constant, probably thanks to the quality protein intake that helped stabilize blood sugar.
Hunger also made itself felt less forcefully. The satiating power of complete proteins has allowed us to get to the main meals without that irrepressible desire for unhealthy snacks. A significant advantage for those trying to manage weight or simply want a more balanced relationship with food.
Finally, having a protein source always ready has simplified meal planning, reducing the stress of “what shall I eat today?” and allowing more informed and peaceful choices.
Because eggs are so nutritious
From a scientific point of view, eggs represent an extraordinary nutritional concentrate with a limited caloric intake. About six grams of protein per egg, complete with all the essential amino acids that our body cannot produce on its own.
Choline, often forgotten when it comes to nutrition, deserves a special mention, as this compound is crucial to brain health and cognitive function, yet many people don’t get enough of it. Eggs are an excellent source.
The much-discussed yolk also contains a treasure of micronutrients: vitamin B12 for the nervous system, vitamin D for bones and immunity, iodine for the thyroid, selenium as an antioxidant. And then lutein and zeaxanthin, two carotenoids that protect eye health and can reduce the risk of macular degeneration.
How to cook eggs matters (and a lot)
Not all preparations are the same. Boiled, poached or steamed, they preserve nutrients without adding unnecessary calories. Frying them in plenty of oil or combining them with bacon and sausages can turn them into a calorie bomb.
The rules to follow are few and simple: focus on minimal processing, limit fats and enhance the natural flavor with aromatic herbs and a drizzle of extra virgin olive oil.
When caution is needed
The experiment yielded positive results for Manaker, but that doesn’t mean eating an egg a day is universally advisable. The most recent scientific evidence suggests that for healthy individuals, dietary cholesterol has less of an impact on blood levels than previously thought, but there are important exceptions.
Those with pre-existing conditions such as high blood cholesterol levels, cardiovascular disease or diabetes should consult their doctor before significantly changing their egg consumption. Each organism reacts differently and personalization remains fundamental.
The final verdict
The week-long experiment convinced Manaker that, in his specific case, a daily egg is a positive addition to his diet. Stable energy, prolonged satiety and simplified food organization are the concrete benefits found.
But really monitoring what we eat and listening to our body’s responses is always the wisest approach. There are no rules that are valid for everyone. Eggs can be precious allies in a balanced diet, as long as they are carefully included in a varied dietary context adapted to your individual needs.
