Eggs


EggsRiverview eggs are a nutritious concentrated source of good quality protein with a wide range of vitamins and minerals. Riverview eggs are great value, easy to cook and a very versatile ingredient for both savoury and sweet dishes. They provide meals in minutes either on their own (boiled, poached, scrambled) or added to other ingredients (quiche, pancakes, omelette).

Remember, dietary guidelines do not apply to a single meal, recipe or food, but to your diet over a period of days or even a week.

Protein

An adequate protein intake is vital for the day to day working of the body. Riverview eggs are an excellent source of protein. A standard portion of eggs (two eggs) provides nearly one third of the daily protein required by an average woman and almost one quarter of an average man's requirement.

Vitamins

Eggs contain substantial amounts of vitamins A, B, D and E.

Vitamin

Function

Vitamin A Maintains healthy immune system, skin and eyes.
Vitamin B2 Involved in energy production.
Vitamin B 12 Involved in cell replication, and healthy blood and nerves.
Vitamin D Important for the development and maintenance of healthy bones.
Vitamin E Acts as a powerful antioxidant – keeps cell membranes healthy.

Minerals

Eggs are a good source of the following minerals:

Mineral

Function

Iron Transport of oxygen around body. Also important for normal growth and development and good immune function.
Phosphorous Important for energy metabolism and healthy bones.
Zinc Involved in over 200 roles in the body including wound healing, healthy hair and skin.
Selenium An important antioxidant.

Recent scientific studies on the effect of eggs on blood cholesterol levels conclude that there is no evidence to show that eating eggs as part of a healthy balanced diet raises blood cholesterol levels and that a healthy adult can eat up to seven eggs a week4.

Cholesterol: Clearing up the confusion

Today, thanks to years of research, we know more than ever about the relationship between diet, lifestyle and good health. It is becoming clear that old perceptions of some dietary issues are inaccurate. For example, research has shown that saturated fat in the diet and not cholesterol in foods has the most influence on blood cholesterol levels1.

For most healthy people saturated fat intake is a more important factor than dietary cholesterol. Although eggs do contain some saturated fat more than half of the fat found in eggs is either monounsaturated or polyunsaturated. Reduce your total intake of fat and eat a balance of the different types of fat.

Eggs & Weight Control

For those interested in weight loss, research indicates that increased protein and reduced carbohydrate intake stabilise blood sugar between meals and reduce snacking. Eggs are a very useful low calorie food that provides large amounts of nutrients.  Because they have no carbohydrates, they do not have a GI (g

lycaemic index) and are useful in a low GI diet.

Two forms of cholesterol exist in your body:

HDL

  • High-Density Lipoprotein good cholesterol.
  • Picks up excess cholesterol from the walls of blood vessels and eliminates it from the body.
  • Regular exercise can help maintain a high level of this good cholesterol.

LDL

  • Low-Density Lipoprotein bad cholesterol.
  • Carries cholesterol around the body and can deposit it in the walls of the blood vessels.
  • Eating foods high in saturated fat and being overweight can lead to an increased level of this bad cholesterol.

Nutrition guidelines recommend that a healthy individual can have up to seven eggs a week2 and those on a cholesterol lowering diet can have four to six eggs a week3.

Fats

The fats found in food fall into three main groups.

Each has a different effect on your cholesterol level.

Fat Types: Where they come from, what they do

Saturated Fat

  • Found mainly in butter, cream, lard, meat fat, chicken skin, cakes, biscuits, chocolate, crisps and deep-fried foods.
    Saturated fats increase cholesterol levels.

Polyunsaturated Fats – PUFA

  • Found mainly in vegetable oils such as sunflower, safflower, corn and soya bean. Brazil nuts, walnuts and oily fish are also rich sources of this type of fat.
    PUFA in small amounts can help lower LDL cholesterol levels.

Monounsaturated Fats – MUFA

  • Found mainly in olive, peanut and rapeseed oils as well as avocados, olives, almonds, hazelnuts and peanuts.
    When substituted for saturated fat, MUFA in moderate amounts can help lower cholesterol levels and maintain the HDL cholesterol levels.

  

A review by Trinity College Dublin, the Egg Scientific Research, has found that while many people are concerned about the cholesterol content of eggs and that there is a popular misconception that cholesterol in food directly influences blood cholesterol. Most recent scientific studies show that this fear is unfounded and seven eggs a week or an egg a day can play an important role in achieving nutritious diet in a healthy child or adult without having an effect on cholesterol levels5.

The review of scientific studies on eggs promotes the consumption of an egg a day provided it is part of a balanced healthy diet that is overall low in fat – with less than 11% of energy from saturated fat, high in fibre and high in fruit and vegetables.
