Basic Egg Facts



Air Cell

The empty space between the white and shell at the large end of the egg.



When an egg is first laid, it is warm. As it cools, the contents contract and the inner shell membrane separates from the outer shell membrane to form the air cell.



The candler uses the size of the air cell as one basis for determining grade. In Grade AA eggs, the air cell may not exceed 1/8-inch in depth and is about the size of a dime. The air cell of Grade A eggs may exceed 3/16-inch in depth. For Grade B eggs, there is no limit on air cell size.



As the egg ages, moisture and carbon dioxide leave through the pores of the shell, air enters to replace them and the air cell becomes larger.



Although the air cell usually forms in the large end of the egg, it occasionally moves freely toward the uppermost point of the egg as the egg is rotated. It is then called a free or floating air cell. If the main air cell ruptures, resulting in one or more small separate air bubbles floating beneath the main air cell, it is known as a bubbly air cell.



You can see the air cell in the flattened end of a peeled, hard-cooked egg.

Albumen

Also known as egg white. Albumen accounts for most of an egg's liquid weight, about 67%. It contains more than half the egg's total protein, niacin, riboflavin, chlorine, magnesium, potassium, sodium and sulfur. The albumen consists of 4 alternating layers of thick and thin consistencies. From the yolk outward, they are designated as the inner thick or chalaziferous white, the inner thin white, the outer thick white and the outer thin white. Egg white tends to thin out as an egg ages because its protein changes in character. That's why fresh eggs sit up tall and firm in the pan while older ones tend to spread out.



Albumen is more opalescent than truly white. The cloudy appearance comes from carbon dioxide. As the egg ages, carbon dioxide escapes, so the albumen of older eggs is more transparent than that of fresher eggs.



When egg albumen is beaten vigorously, it foams and increases in volume 6 to 8 times. Egg foams are essential for making souffles, meringues, puffy omelets, and angel food and sponge cakes.



The yolk or yellow portion makes up about 33% of the liquid weight of the egg. It contains all of the fat in the egg and a little less than half of the protein.



With the exception of riboflavin and niacin, the yolk contains a higher proportion of the egg's vitamins than the white. All of the egg's vitamins A, D and E are in the yolk. Egg yolks are one of the few foods naturally containing vitamin D.



The yolk also contains more phosphorus, manganese, iron, iodine, copper, and calcium than the white, and it contains all of the zinc. The yolk of a Large egg contains about 59 calories.



Double-yolked eggs are often produced by young hens whose egg production cycles are not yet completely synchronized. They're often produced, too, by hens who are old enough to produce Extra Large eggs. Genetics is a factor, also. Occasionally a hen will produce double-yolked eggs throughout her egg-laying career. It is rare, but not unusual, for a young hen to produce an egg with no yolk at all.

Water is the most abundant nutrient in our body and plays an important transmission function in every body cell and tissue. Sixty percent of our body weight is water. The fact that you can live without food for a long period of time, even months, but live only for a few days without water is true. Under normal conditions, the body releases about one quart of water daily. Therefore, replacement to equal the losses is very important for survival.

Dehydration is the most common problem of water imbalance due to water losses and deprivation. The effects of dehydration on nutrition can adversely affect ones health. Dehydration is the major cause of ones diminished ability to perform during endurance activities. Body water is lost through the stomach, respiration, sweat, and the kidneys. It is recomended that 24oz of water a day should be taken. This amount can double or even triple with endurance type exercise.



A note about water: More and more evidence shows the benifit of being well hydrated.

Studies show that 75% of Americans are chronically dehydrated (likely applies to half the world's population), leading to possible health problems such as fatigue. In 37% of Americans, the thirst mechanism is so weak that it is often mistaken for hunger, leading to over-eating. Even MILD dehydration will slow down one's metabolism as much as 3%.



Bottled Water: Some types of bottled water are not subject to the same regulations as tap water. These are regulated as food products, and their regulations are largely related to sanitary food handling and processing practices. Bottled water manufacturers will provide a detailed report on the quality of their product to consumers who call to request it.

Flavor(s) Natural

Under the Code of Federal Regulation, natural flavor is defined as “the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating, enzymolysis (biochemical decomposition of a substance), which contains the flavoring constituents derived from a spice, fruit or fruit juice, vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs , dairy products, or fermentation products thereof, whose significant function in food is flavoring rather than nutritional.” Natural flavoring substances are obtained from plant or animal raw materials, containing no other artificial or added ingredients. Spices approved by the Food and Drug Administration (FDA) such as black pepper and basil do not have to be listed under its specific name. Additives can also be listed under natural flavoring because they might meet FDA definition standards, the extraction process consider flavorings man-made. In addition, spice extracts, essential oils, oleoresins, onion powder/juice, and garlic powder/juice are allowed to be labeled under “flavor” or “natural flavor.”

A gummy substance obtained from legume-family plants, used as a thickener and STABILIZER in commercial food processing.

Produced from the fermentation of corn SUGAR, xanthan gum is used as a thickener, EMULSIFIER and STABILIZER in foods such as dairy products and salad dressings.

Some people are allergic to xanthan gum, with symptoms of intestinal gripes, diarrhea, temporary high blood pressure, and migraine headaches

Also, since xanthan gum is produced by a bacterium that is fed corn to grow, some people allergic to corn will also react to it. Yellow Phrygian Husk is a common source of bacterium in which xanthan gum is created

Also used by people who are allergic to gluten

One of the most important and abundant of the carotenes, a portion of which the liver converts to vitamin A. It should be noted, however, that while excess vitamin A can be toxic to the body, residual beta carotene is quickly eliminated. Scientists now believe that beta carotene is a powerful ANTIOXIDANT with properties that can contribute to reducing cancer and heart disease. It's found in vegetables like carrots, broccoli, squash, spinach and sweet potatoes. Beta carotene's orange-yellow pigment is also used as a coloring in foods like butter and margarine.Carotenoids are the red, orange and yellow plant pigments that give fruits and vegetables their vivid colors. All fruits and vegetables contain varying concentrations of carotenoids, but their colors are often covered up by green chlorophyll contained in the plant.



There are more than 600 different naturally-occuring carotenoids. Some of them have been identified as playing a vital role by protecting our cells and tissues from the damaging effects of free radicals and singlet oxygen. Lycopene, the carotenoid that gives tomatoes their red color, is particularly effective at quenching the destructive free radical singlet oxygen.

Researchers at the USDA Human Nutrition Center (HNRCA) have found that blueberries rank #1 in antioxidant activity when compared to 40 other fresh fruits and vegetables. Antioxidants help neutralize harmful by-products of metabolism called "free radicals" that can lead to cancer and other age related diseases. Anthocyanin -- the pigment that makes the blueberries blue -- is thought to be responsible for this major health benefit.

In another USDA Human Nutrition Center (HNRCA) lab, neuroscientists discovered that feeding blueberries to laboratory rats slowed age-related loss in their mental capacity, a finding that has important implications for humans. Again, the high antioxidant activity of blueberries probably played a role.

A one cup serving of blueberries contains 16% DV of fiber. Blueberries are a source of Vitamins A and C, potassium and folate.

Blueberries are very low in fat and sodium.

A product that has GRAS status, acidified calcium sulphate is an organic acid and calcium sulfate combination that kills Listeria on the surface of products such as lunchmeats and certain cheeses, and keeps the bacteria from growing back. Listeria is responsible for causing foodborne listeriosis, which causes flu-like symptoms, meningitis, spontaneous abortions and prenatal septicemia. About 20% of the illnesses are fatal.



Until now, lactic acid and sodium lactate have offered some microbiological protection, but they cannot completely stop the organisms from reappearing. However, a study carried out at Texas A&M University and funded by the American Meat Institute Foundation demonstrates the acidified calcium sulphate appears to be able to do so.

Vitamin A is very important for maintaining good vision. In fact, the first sign of a vitamin A deficiency is often night blindness. Vitamin A also contributes to the maintenance of healthy skin and mucous membranes that line the nose, sinuses, and mouth. Research has shown that this nutrient is necessary for proper immune system function, growth, bone formation, reproduction, and wound healing. Animal studies also suggest that it provides some protection from toxic chemicals such as dioxins. (Dioxins are released into the air from combustion processes such as commercial waste incineration and burning fuels like wood, coal or oil. These chemicals can also be found in cigarette smoke.)

sodium phosphate with ferric chloride or ferric citrate.

iron, iron sulfate, Used in the food industry as a carrier for iron.



Iron in the body works with proteins that release energy in metabolism such as hemoglobin, which carries oxygen in the blood stream. Also involved in the making of ammino acids, hormones, and neurotransmitters.

Iron can be found in meats, poultry, and fish and many fortified foods. Fruits, vegetables and juices also provide some iron.

Iron deficiency symptoms include; anemia, inability to concentrate, weakness, fatigue, pallor, being out of breath after small exertion, cold hands and feet. Some people may develop a smooth round tongue, and have difficulty swallowing.



Symptoms of overload include: nausea, vomiting, diarrhea, rapid heartbeat, dizziness, shock and even death.



***Parents should be warned that iron supplements and multivitamins containing iron are the second most common cause of poisoning in young children in the U.S. (Aspirin is the first) The lethal dose of ferrous sulfate for a 2-year-old is only 3g.***

Vitamin E



Found in almonds, apricot oil, corn oil, cottonseed oil, hazelnuts, margarine, peanut oil, safflower nuts, sunflower seeds, walnuts, wheat germ, whole-wheat flour

Vitamin E is an antioxidant.Its action is enhanced by ascorbic acid and selenium. It protects polyunsaturated fats in the body from oxidation, maintains the integrity of vitamin A in the body and promotes normal clotting of blood. It's levels in the body are dependenent on proper levels of zinc.Promotes normal growth and development Prevents free radical damage in body Acts as anti-blood clotting agent Protects tissues against oxidation Promotes normal red blood cell formation Helps treat fibrocystic disease of the breasts Helps treat circulatory problems of lower extremities Helps in treatment of sickle-cell anemia Protects lungs from air pollution Helps prevent coronary-artery heart disease Improves stamina Heals burns and wounds Helps retard aging Lessens some types of hair loss Eases menopause Dimineshes liver spots Useful as an adjuct treatment for Bursitis Prevents diaper rash Decreases scarring Useful in treatment of anemia Helps heal acne.

Vitamin E, a fat-soluble vitamin, protects vitamin A and essential fatty acids from oxidation (antioxidant)in the body cells and prevents breakdown of body tissues.



Found natural in Vegetable oil, Spinach, whole grains and sunflower seeds.



Deficiency Symptoms: Rare symptoms may include anemia & edema



Toxicity Symptoms: Generally non-toxic; nausea, dizziness & diarrhea can occur

The term “vitamin E” refers to a family of eight related, lipid-soluble, antioxidant compounds widely distributed in plants. The tocopherol and tocotrienol subfamilies are each composed of alpha, beta, gamma, and delta vitamers having unique biological effects. Different ratios of these compounds are found in anatomically different parts of a plant. For example, the green parts of a plant contain mostly alpha-tocopherol and the seed germ and bran contain mostly tocotrienols. Along with other nutrients tocopherols and tocotrienols are concentrated in the bran layers of the rye grain, and are only present at low levels in the flour endosperm. Tocopherols are also present in algae, mint teas, and other food stuff.87-93



When this family of compounds was first discovered and determined to be essential for health, a standardized test for its activity was devised for which the members of the family were rated for their biological activity. In one test, alpha tocopherol scored highest and was rated 100% with all others having lower ratings. In accordance with this rating, alpha-tocopherol was deemed to be the essential compound and was called vitamin E. One International Unit (IU) of vitamin E activity is the activity under this rating of one mg of the plant-derived form of alpha-tocopherol.94



Since the original rating method was established, many additional important biological effects of these compounds have been discovered and many nutritional scientists now consider that rating method to be incomplete. For example, by the original rating, gamma-tocopherol was only 10% to 30% as strong as alpha-tocopherol, yet more recent studies have shown it to be essential for maintaining the health of cell membranes, especially if alpha-tocopherol is being supplemented. New studies continue to elucidate the unique benefits of individual members of the vitamin E family. For these and other reasons, the original definition of vitamin E has been enhanced to include all eight family members and the related compounds that convert to them in the body.94



Vitamin E compounds are usually produced and made available in esterified form as alpha-tocopheryl acetate or alpha-tocopheryl succinate. Neither of these forms has any antioxidant activity until converted to alpha-tocopherol in the body, but they are much more stable with respect to storage time and temperature than the unesterified forms. Moreover, while the acetate form is rapidly activated within the body, activation of the succinate form is slower. The succinate form appears to access and benefit areas of the tissues that are unavailable to the other forms. For this reason, there is a tendency to regard alpha-tocopherol succinate as a distinctly different and beneficial compound. Alpha-tocopherol succinate appears to have longer half-life in the body, and does not interfere with vitamin A or K absorption.95-98



Serious vitamin takers prefer cold-water dispersible dry powder vitamin E supplements in the form of alpha-tocopheryl succinate or acetate because the cold-water dispersible forms are efficiently absorbed even when taken on an empty stomach or with a low-fat meal. The non-cold water dispersible (oil) forms of vitamin E may be poorly absorbed unless taken with several grams of fats or oils.



Cold-water dispersible vitamin E is more efficiently absorbed than some other forms. Both “acetate” and “succinate” vitamin E can come from natural sources. The importance to the consumer is how well the vitamin E absorbs into the bloodstream. Cold-water dispersible vitamin E, whether in a succinate or acetate form, always comes in a white dry powder, while non-cold water dispersible natural and synthetic acetate forms of vitamin E are always in a thick brown oil.

Calciferol, Calcipotriol, Cholecalciferol, Irradiated Erogcalciferol



A vitamin produced by the body when exposed to ultraviolet light or obtained from dietary sources. Vitamin D3 is a hormone that has an important role in calcium and phosphorus metabolism and for the assimilation of Vitamin A. It may also has a strong immune enhancing effect. Technically, vitamin D3 is not a vitamin because the body can produce it



Deficiency: People need vitamin D3 to treat menopausal systems, to prevent osteoporosis in postmenopausal women and as replacement therapy in other conditions of inadequate estrogen production.

This is a mineral used to treat or prevent low levels of zinc. It may also be used to treat other conditions as determined by your doctor. Though there is no prof, people have claimed it has helped with hair loss.



Zinc is a essential element for humans; naturally occurs in meat (especially liver), fish (especially shellfish), lentils, green leafy vegetables, whole cereals (including wheat germ), brewer's yeast, cheese, milk, nuts, sunflower and sesame seeds; toxic doses of zinc cause vomiting, diarrhea, restlessness, stomach irritation, depressed immune function and anemia; excessive zinc doses may decrease the level of HDL ("good") cholesterol and increase the risk for heart disease.

Pantothenic acid, also called vitamin B5 (a B vitamin), is a water-soluble vitamin required to sustain life (essential nutrient). Pantothenic acid is needed to form coenzyme-A (CoA), and is critical in the metabolism and synthesis of carbohydrates, proteins, and fats. In chemical structure, it is the amide between D-pantoate and beta-alanine. Its name is derived from the Greek pantothen (pa?t??e?) meaning "from everywhere" and small quantities of pantothenic acid are found in nearly every food, with high amounts in whole-grain cereals, legumes, eggs, meat, and royal jelly. It is commonly found as its alcohol analog, the provitamin panthenol, and as calcium pantothenate.

Vitamin B12, also called cobalamin, is important to good health. It helps maintain healthy nerve cells and red blood cells, and is also needed to make DNA, the genetic material in all cells . Vitamin B12 is bound to the protein in food. Hydrochloric acid in the stomach releases B12 from protein during digestion. Once released, B12 combines with a substance called intrinsic factor (IF) before it is absorbed into the bloodstream.

Good sources include meat, particularly liver, salmon, cod, milk, cheese, eggs, yeast extract, and some fortified breakfast cereals.

Vitamin B-1, Perfectly safe, despite adding minuscule amounts of nitrate to our food.

Vitamin B1 is also known as thiamine, thiamin and aneurin. Thiamine is the currently accepted name for vitamin B1 in the US. Aneurin is still widely used in Europe, especially in the United Kingdom.

Necessary for proper metabolism of sugar and starch to provide energy. Maintains a healthy nervous system as well as aiding proper function of the heart and other muscles. Stress increases the need for B-1 and all B vitamins.

Pyridoxine Hydrochloride

Activated vitamin B-6 is extensively involved in the metabolism of amino acids. efficiently from pyridoxine in the liver. Ex cessive protein intake, alcohol or contraceptive use also indicates a greater need for vitamin B-6. It also plays a crucial role in the multiplication of cells.

Vitamin B6 is a water-soluble vitamin This means you need it in your diet every day because it cant be stored in the body.that exists in three major chemical forms: pyridoxine, pyridoxal, and pyridoxamine, It performs a wide variety of functions in your body and is essential for your good health. For example, vitamin B6 is needed for more than 100 enzymes involved in protein metabolism. It is also essential for red blood cell metabolism. The nervous and immune systems need vitamin B6 to function efficiently, and it is also needed for the conversion of tryptophan (an amino acid) to niacin (a vitamin)

Vitamin B2, or riboflavin, is required to complete several reactions in the energy cycle. Reddening of the lips with cracks at the corners of the mouth, inflammation of the tongue, and a greasy, scaly inflammation of the skin are common symptoms of deficiency.Riboflavin (B2)- Classic riboflavin deficiency involves the lips, tongue, eyes, skin and nervous system. Vision changes, cheliosis (tiny lesions in the mouth or cracks in the corners of the mouth) tongue inflammation and discomfort eating or swallowing.



Riboflavin?s role in the body involves the metabolism of fats and proteins. Enzymes influenced by riboflavin are absolutely necessary to transport oxygen to the cells. A decrease in this vitamin can result in fatigue. New research indicates that migraine headache sufferers may benefit by riboflavin. 400mgs.day have been shown to lessen the incidence of migraines.



Required for red blood cell formation, antibody production, cell respiration and growth. Important for good muscle tone. Involved in metabolism of protein, protein fats, and carbohydrates. Necessary for good vision, skin, hair and nails.

Folic acid is the synthetic form of the B vitamin folate. Folic acid is necessary for the synthesis of nucleic acids and the formation of red blood cells. Folic-acid deficiency most commonly causes folic-acid-deficiency anemia. Symptoms include gastrointestinal problems, such as sore tongue, cracks at the corners of the mouth, diarrhea, and ulceration of the stomach and intestines. Large doses of folic acid can cause convulsions and other nervous-system problems.

The Food and Drug Administration (FDA) regulations require enriched grain products to contain this essential vitamin.



Current studies have discovered a link between folic acid and brain function in older people. The study divided 818 people ages 50 to 75 to take either a vitamin containing 800 micrograms of folic acid a day, or a dummy pill, for three years.



On memory tests, the supplement users had scores comparable to people 5.5 years younger, Durga said. On tests of cognitive speed, the folic acid helped users perform as well as people 1.9 years younger.
