Eating three eggs a day is generally considered safe for healthy adults who do not have any underlying health conditions. Eggs are an excellent source of protein, vitamins, and minerals, and can be a healthy addition to your diet.

However, it's important to note that eggs are also high in cholesterol, with one large egg containing about 186 mg of cholesterol. Therefore, if you already have high cholesterol or a history of heart disease in your family, it's recommended that you limit your egg intake to no more than three yolks per week.

Additionally, the way you prepare your eggs can also impact their nutritional value. Boiled, poached, or scrambled eggs with minimal added fats and seasonings are generally considered healthier options than fried or heavily seasoned eggs.

It's always a good idea to talk to a healthcare professional or a registered dietitian if you have any concerns about your diet or overall health.
