Eggs are scientifically proven to contain many nutrients that are beneficial to health, especially the abundant source of protein in eggs. There are many ways to prepare eggs, from boiling, frying to baking with the shell still on. Experts recommend not to cook eggs at too high a temperature because it can be harmful to health.
An average egg contains 186 mg of cholesterol. Some people are concerned that the cholesterol content in eggs can cause cardiovascular problems. However, the American Heart Association (AHA) says that eggs are not the cause of high cholesterol. Therefore, eating one egg a day is safe for your health, according to the health website Healthline (USA).
Cooking eggs at too high a temperature can create chemicals that are harmful to health.
However, one thing people need to keep in mind when preparing eggs is to avoid using too hot a temperature. Because when cholesterol in eggs is exposed to high temperatures, it can produce a compound called oxysterol. Some research evidence shows that oxysterol has many negative effects on health, including increasing the risk of heart disease and cancer.
A study published in the International Journal of Molecular Sciences found that cholesterol in eggs can be converted to oxysterols during storage and processing. Additionally, if blood cholesterol levels are too high, the liver can convert cholesterol into oxysterols. High cholesterol levels and type 2 diabetes can increase oxidation in the body, leading to the production of more oxysterols.
Oxysterols can bind to LDL “bad” cholesterol, thereby accelerating the process of atherosclerosis and creating many agents that cause oxidative stress. Oxidative stress will make the DNA in cells vulnerable, thereby increasing the risk of cancer.
Although high temperatures can convert cholesterol in eggs into oxysterols, this does not mean that eggs should not be cooked. Eggs still need to be cooked to kill bacteria and pathogens. However, people should only cook eggs at moderate temperatures.
The best way to cook eggs is to use a low temperature and maintain it for long enough to cook the eggs. If frying, do not use too much oil. In fact, eggs do not need to be overcooked to be safe for health.
In addition, experts recommend that if you are concerned about oxysterols, in addition to avoiding cooking eggs at too high a temperature, you should also limit deep-fried meats and processed foods such as cold cuts and sausages, according to Healthline.
