About five percent of eggs have a fishy odor. This is also genetic and is caused by a gene defect.
The colorless gas trimethylamine is deposited in the yolk of predominantly brown eggs. Due to the gene defect, the TMA precursor compound choline, which is present in the animals’ feed, cannot be converted by the enzymes to an odorless TMA oxide.

Eggs are a true power food
We now know that eggs are not exactly a low-fat food, but the good thing about them is that they contain valuable omega-3 fatty acids, which are now widely promoted as having a positive effect on the blood vessels in humans. If one looks at sausage and Co. one finds out fast that these cause substantially more damage in the organism in view of their saturated fatty acids.
Protein, as the absolute building block of life, is one of the main components of chicken egg and provides essential amino acids, especially for humans, which humans cannot produce themselves. Egg white or protein is needed for

Cholesterol and chicken eggs – How much can you eat??
In former times it was always said that the consumption of eggs makes the cholesterol level rise. This has been disproved by several studies in the meantime.
Many people who want to eat healthily abstain from eating eggs or at least limit them drastically. But this is not necessary at all. Most people can consume eggs without remorse.
Cholesterol production in the body
Eggs contain relatively high amounts of cholesterol, that is true. Every human body also produces cholesterol. If additional amounts of cholesterol are added to the diet, the healthy body normally recognizes this and produces correspondingly less.
Therefore, if you eat a boiled egg in the morning, you do not automatically have an elevated level of cholesterol in your blood. By the fact that the body produces less, the cholesterol level does not change. The fact that only three eggs per week should be consumed is therefore invalid.
However, there are some exceptions: In some people, it is actually the case that the body nevertheless forms the normal amount of cholesterol, regardless of what has been eaten. In other people, however, less cholesterol is produced by the body when cholesterol-rich foods such as eggs are consumed.
Before you give up your beloved breakfast egg, just to possibly keep your cholesterol level from skyrocketing, you should have your blood tested. For this purpose, a small quantity is sufficient, which can be taken as part of a blood sample from any family doctor. This allows the doctor to determine cholesterol levels and whether they are within the normal range.
The sole renunciation of eggs does not help
If the cholesterol level in the blood is too high, it is by no means enough to just abstain from eating eggs. Cholesterol, i.e. fats, are mainly found in foods such as sausage and meat with a high fat content.
These products should be avoided or at least only eaten now and then. In addition one must do sport, if one would like to lower its Cholesterinwerte.
Those who abstain from eggs alone and instead eats greasy roast pork and only leaves the couch to get beer, can in no way lower its cholesterol levels.
Suitable for losing weight – with eggs to the dream figure?
Regarding the health value, it can be said that eggs seem to promote weight loss when eaten for breakfast. An American study on this thesis should enlighten:
In the study 152 overweight test persons were divided into two groups. The one group got a classical bagel breakfast in the morning. The other received a breakfast that was calorically equal to the bagel breakfast, but on Eggs as the main ingredient recourse.
The members of the egg group had lost more weight at the end of the test period and felt more agile than the bagel group. The egg eaters had a total 65 percent higher weight loss to be recorded. However, an increase in cholesterol or triglycerides in the blood could not be detected.
The responsible researchers from the "Louisiana State University" had a very good idea of the study assume that eggs kept the test persons fuller for longer, which is why they apparently strictly followed the dietary guidelines. Why eggs have such a strong satiating effect, a follow-up study should find out.
Storage and shelf life of eggs
From the date of laying the eggs can be Store unrefrigerated for 18 days, which is made possible by the calciferous eggshell’s own immune protection and by internal enzymes. However, the eggs must not be washed during this period, otherwise the cuticle would be destroyed.
After the first 18 days, the eggs must be continuously cooled. The best before date is 28. Day from the day of laying.
Whether an egg is still fresh or not can be easily determined by a test. To do this, place the egg in a glass of water. If the egg is still very fresh, it remains at the bottom, but if it is older than 28 days, it floats to the surface.
Since raw chicken eggs are very sensitive and an ideal breeding ground for bacteria such as salmonella, strict food regulations apply. Thus, the egg must be delivered to the consumer in a period of 21 days.
In addition, eggs are very fragile, which requires extreme caution during transport. Egg cartons are mostly used as transport containers.
