The world record for most-liked Instagram post (more than 53 million) is a photo of a brown egg posted by @world_record_egg.

Initially, the likes were fueled by the fact that no one could figure out who posted it or why. (It's an advertising campaign for mental health awareness.)

But there has always been a lot of mystery surrounding eggs — including a longstanding debate over whether or not they're good for your health.

Recent changes made to U.S. dietary guidelines didn't clarify anything. They suggest that eating an egg once a week is part of a healthy diet, and said that the daily limit of cholesterol from food should be 100 mg to 300 mg, depending on your appropriate calorie intake level.

People took that to mean that eating an egg or two some days was okay because one egg has around 187 mg of cholesterol.

Not so fast. A study published in JAMA looked at data on almost 30,000 adults and found eating three to four eggs weekly was associated with 6 percent higher risk of cardiovascular disease and 8 percent higher risk of any cause of death.

And getting 300 mg of dietary cholesterol daily was associated with a 17 percent increase in your risk of cardiovascular disease.

Clearly, more than one egg yolk a week could scramble your health.

Here’s a smart alternative: Stick with cholesterol-free egg whites and veggies for a tasty omelet.

One egg white delivers 4 grams of protein, 2.3 mg of calcium, 3.6 mg of magnesium, and 53.8 mg of potassium in just 17 calories.
