Concerns about eggs

Over the years a few concerns have been raised about eggs. Most of them have been proven to be without merit. Here are some of the concerns:

Cholesterol

Eggs do contain cholesterol; however the cholesterol in your body is determined by the quantity of saturated fat that you eat rather than from the eggs.

Processed meats like ham, sausages and fatty cats of beef, pork and lamb as well as the skin of chicken contain a lot of saturated fats. To lower your cholesterol levels, look into cutting out from your diet processed foods and convenience foods.

One egg, which is recommended to be eaten per day, contains a third of the daily cholesterol limit.

Food poisoning

Raw eggs or partially cooked eggs with a runny yolk can cause food poisoning. This is especially true for groups of people who are vulnerable such as children, pregnant women, ill and elderly people.

The raw eggs may contain Salmonella bacteria, which is destroyed by cooking. If you’re incorporating raw egg into a recipe, a safer option would be to use pasteurised eggs.

To be safe, ensure that your eggs are well cooked before eating them and store them correctly by:

  • Storing them in a cool, dry place such as the refrigerator
  • Ensuring that they are stored separated from other foods
  • Discard eggs with broken shells as they may contain bacteria
