Are eggs harmful to dogs?
Raw eggs are harmful to dogs, because they contain an enzyme called avidin, which decreases the absorption of biotin (a B vitamin). This can lead to skin and hair coat problems. Raw eggs may also contain Salmonella.
Who discovered biotin?
W. G. Bateman discovered biotin in 1916. That adding raw eggwhite to an otherwise adequate diet produced toxicity and disease. Called egg-white injury, the symptoms includedeffects on the skin (scaly dermatitis and hair loss), thenervous system (depression, lassitude, and muscle pain),the gastrointestinal tract (anorexia and nausea), and even the cardiovascular system (abnormal heart action, i.e.,changes in the electrocardiogram). Later research identified the culprit to be avidin, a protein in egg white which avidly binds biotin, preventing its absorption. Thus, the biological necessity of biotin became evident, and by 1935scientists had isolated it in pure form. Biotin, originally calledvitamin H after the German word Haut meaning "skin", belongs to the water soluble B vitamin class.
Is eating raw eggs good?
Eating raw eggs is thought to help in building muscle as they contain essential amino acids which are necessary for muscle growth and repair, however if you were to eat raw eggs, remember to do so in moderation.Egg whites contain a protein known as avidin which permanently binds to biotin, a cofactor responsible for many essential biochemical processes within our bodies. When an excessive amounts (>20) of raw egg white is digested a biotin deficiency is created which can ultimately lead to death.Salmonella is also a risk however the risk is extremely low (~1 egg in every 20,000 are estimated to be infected with Salmonella enteritidis).Depends.Eggs as such are a good source of protein. However, raw eggs MAY have a bacteria called Salmonella in them, which can make you really sick. Unless you trust the supplier it's better to cook them first.
Biotin use and crohns disease?
Biotin is a water soluble vitamin generally classified as a B complex vitamin. Although Biotin deficiency is VERY rare, human deficiency has been demonstrated for two different situations. Prolonged Intravenous feeding without Biotin supplementation and the biggest reason lately has been, the use of Raw egg whites by "body builders" and those on a "special" diet regimen touting the drinking of Raw egg whites. Avidin is a protein found in raw egg whites and it binds Biotin preventing its absorption. Symptoms of deficiency are hair loss, scaly red rash at the nose, mouth and genitalia. Depression, lethargy and numbness of the extremities. Biotin is not known to be toxic and doses up to 200 mg/day are well tolerated. As non of the current drugs used to control crohns disease are known to be contra indicated with usage of Biotin you should be OK. As always, speak with your crohns management team to verify this advise.
What are the nutrients in egg?
An egg is really three separate foods, the whole egg, the white, and the yolk, each with its own distinct nutritional profile. A whole egg is a high-fat, high-cholesterol, high-quality protein food packaged in a high-calcium shell that can be grounded and added to any recipe. The proteins in eggs, with sufficient amounts of all the essential amino acids, are 99 percent digestible, the standard by which all other proteins are judged. The egg white is a high-protein, low-fat food with virtually no cholesterol. Its only important vitamin is riboflavin (vitamin B2), a visible vitamin that gives egg white a slightly greenish cast. Raw egg whites contain avidin, an antinutrient that binds biotin a B complex vitamin formerly known as vitamin H, into an insoluble compound. Cooking the egg inactivates avidin. An egg yolk is a high-fat, high-cholesterol, high-protein food, a good source of vitamin A derived from carotenes eaten by the laying hen, plus vitamin D, B vitamins, and heme iron, the form of iron most easily absorbed by your body. One large egg has 5 g Eat (1.5 g saturated fat), 212 mg cholesterol, 6 g protein, 950 IU vitamin A (19 percent of the RDA for a man, 23.7 percent of the RDA for a woman), and 0.72 mg iron (4.8 percent of the RDA for a woman of childbearing age). One large egg white has 4 g protein, but no Eat or cholesterol. One large egg yolk has 6 g fat (1.7 g saturated fat), 272 mg cholesterol, 3 g protein, and 970 IU vitamin A (19.4 percent of the RDA for a man, 24 percent of the RDA for a woman). The most nutritious way to server egg is with extra whites and fewer yolks to lower the fat and cholesterol per serving. Those on controlled-fat, low-cholesterol diet or low-protein diet should exclude this food.
