Eggs are nutritious, affordable, and easy to cook. Yet in daily life, I notice many questions about whether to eat one or two eggs, or whether egg whites or yolks are better. Today, I'll address these common concerns for different groups.
Question 1: I have high blood pressure. Can I eat one egg daily? How should I prepare it?
Answer: People with hypertension can safely consume one egg per day.Hypertension is a major risk factor for stroke. International studies show that eating one egg daily does not affect blood pressure control or increase stroke risk. Some epidemiological research even suggests a negative correlation between egg consumption and stroke risk. What hypertension patients should focus on is how to cook eggs healthily. First, use minimal oil. For example, poach eggs until tender, chop them, then mix with a little sauce for a tasty dish.Second, minimize salt usage. For instance, gently pan-fry an egg in a non-stick pan or poach it in a small amount of water, seasoning only with a dash of soy sauce. Regularly consuming egg drop soup is not recommended, as adding salt to a large bowl of soup can easily exceed daily salt intake limits. If you enjoy egg drop soup, strictly control the salt amount.
Question 2: I've been under a lot of stress lately. I heard you should only eat one egg per day, otherwise it's hard to digest and absorb, and the protein goes to waste. Is that true?
Answer: Adolescence is the period of fastest growth and highest nutrient demand in a person's life. Taking males as an example, according to China's Dietary Reference Intakes, the daily calorie requirement for adolescent males is 250 kcal higher than that of ordinary adults, and protein intake is 10 grams higher.One egg contains only 6–7 grams of protein and less than 80 kcal. For adolescents, consuming two eggs daily is perfectly acceptable. Whether protein intake becomes excessive or wasted depends on the total amount of protein-rich foods consumed daily—such as fish, meat, eggs, dairy, and soy products—not just the number of eggs eaten.
Question 3: Is it true that eggs are high in fat and cholesterol, making them unsuitable for people with cholecystitis?
Answer: Egg whites contain almost no fat (less than 1%) and no cholesterol. However, they also lack many vitamins, minerals, dietary fiber, and lecithin found in egg yolks. People with cholecystitis can eat egg whites, but yolks are indeed not recommended.Overall, without the yolk, egg whites offer less nutritional value than tofu. Soy products contain dietary fiber and phytosterols, which help reduce the body's cholesterol absorption. When prepared with minimal oil, they are more beneficial for gallbladder disease patients than eggs.
Question 4: I have gout and only eat egg whites, avoiding yolks to prevent high cholesterol. Is this correct?
Answer: Eggs and all egg products contain extremely low levels of purines, making them suitable for individuals with gout or hyperuricemia. Consuming one egg yolk is perfectly acceptable, as the majority of micronutrients are concentrated in the yolk.Gout patients who avoid fish, meat, seafood, and soy products are prone to deficiencies in B vitamins and trace minerals. Unless you have gallbladder inflammation or other issues, and without specific medical advice, consuming two egg yolks is acceptable. However, ensure you increase vegetable intake to guarantee adequate dietary fiber and potassium.How should eggs be consumed in this situation?
Answer: Low serum albumin indicates malnutrition and insufficient protein intake. Many hospitalized patients consume only plain congee or noodles, which fail to provide adequate protein and B vitamins for recovery. Compared to these foods, eggs offer higher quantity and quality of easily digestible protein. Since previous intake was inadequate, additional protein is essential to correct malnutrition. Therefore, consuming two eggs daily is perfectly acceptable.
Note that one egg contains only 6–7 grams of protein. Without fish, meat, tofu products, or dairy, consuming just two eggs plus staple foods still won't meet the patient's daily protein needs. In addition to eggs, moderate amounts of meat, fish, milk, and soy products should be included—provided the patient can digest them normally.
Question 6: I'm in my second trimester and love eating eggs. Is it okay to have two daily?
Answer: Both the second and third trimesters require increased protein intake. During the second trimester, daily protein intake should increase by 15 grams compared to pre-pregnancy levels—equivalent to one cup of milk plus one egg. Therefore, as long as fish and meat consumption isn't excessive, pregnant women can safely eat two eggs daily.
Question 7: I'm currently working out to build muscle, but my trainer restricts me to no more than 2 eggs per week, claiming they're hard to digest and recommending whey protein powder instead. Is eating just 1 egg daily really not okay?
Answer: Compared to dense beef, eggs are relatively easy to digest. Whether soft-boiled, lightly fried, in custard, or in soup, they have high digestibility. Fitness enthusiasts can safely consume 1–2 eggs daily.While whey protein powder is rich in leucine and may offer slightly better muscle-building effects than egg whites for the same protein intake, non-bodybuilders not seeking rapid muscle growth need not rely heavily on protein powder or worry about the minimal fat in egg yolks. Adding one extra egg and one extra glass of milk to a balanced diet is sufficient to meet muscle-building protein needs.▲(Fan Zhihong, Associate Professor, College of Food Science and Nutrition Engineering, China Agricultural University)
