Although warnings regarding the side effects of calcium supplements have been reported, the results of a scientific study on the benefits and risks of eggshell consumption have been published.
According to Healthline, eggshells are made of calcium carbonate, a common form of calcium, protein and other minerals.
Calcium is also known to be a basic and abundant mineral in many foods, including dairy products. Fewer amounts were also found in many leafy vegetables and roots.
The use of chicken egg shell powder as a natural supplement to calcium is not an innovation, but the most common method for obtaining calcium in recent centuries. Half of an eggshell provides the daily needs of an adult at 1,000 mg. Calcium accounts for 40% of the shell content, which corresponds to about 400 mg per gram of shell.
Egg powder
Egg shells consist of calcium carbonate, as well as small amounts of protein and other organic compounds.
Calcium carbonate is the most common type of calcium in nature because it is a major component of crustaceans, coral reefs and limestone. These are also the cheapest types of calcium in dietary supplements.
Scientific studies confirm that body cells absorb 64% more natural calcium carbonate in eggshell powder than pure industrial calcium carbonate. Researchers justify the reason for the proteins available in eggshell powder that facilitate the absorption of natural calcium.
In addition to calcium and protein, eggshells also contain small amounts of other minerals, including strontium, fluoride, magnesium and selenium, which play a role in bone health, like calcium.
osteoporosis
Osteoporosis is a health problem that leads to bone breakdown and therefore increases the risk of fractures. Millions of people around the world suffer from osteoporosis, the largest proportion of which is composed of women.
Aging is one of the most important risk factors for osteoporosis, but inadequate calcium intake can lead to bone loss and osteoporosis over time.
If a person's diet lacks calcium, taking supplements can help meet the body's daily needs. The eggshell, in this case, is a physically appropriate option for all classes.
In a study of postmenopausal women with osteoporosis, eggshell powder, combined with vitamin D3 and magnesium, significantly improved bone mass by improving bone mineral density.
The egg bark powder is more effective than pure calcium carbonate to reduce the risk of osteoporosis.
Another study conducted in Holland on postmenopausal women found that eggshell powder improves bone mineral density compared to placebo. In contrast, industrial calcium carbonate did not improve the condition significantly.
Benefits of the egg-skin membrane
The egg-skin membrane is located between the eggshell and the egg whites. This is easily seen when you peel a boiled egg.
Although technically it is not part of the eggshell, it is usually associated with it. Therefore, it is not necessary to remove the membrane when working at home with powder for egg peels.
The egg-skin membrane is mainly composed of proteins in the form of collagen. It also contains small amounts of chondroitin sulfate, glucosamine and other nutrients.
The limited amount of these beneficial compounds in the shell membrane of the egg is unlikely to have any significant effects on your health.
However, some studies, which require extensive research, suggest that regular consumption of eggshell membrane supplementation is beneficial for the joints.
Risks of eating a shell
When properly prepared, the eggshell powder is considered perfectly safe. But there are some precautions to follow:
First, do not try to swallow large fragments of eggshells, as they could hurt the throat and the esophagus.
Secondly, eggshells may be contaminated with bacteria, such as salmonella. To avoid the risk of food poisoning, be sure to boil the eggs before eating the peel.
Finally, natural calcium supplements may contain relatively high amounts of toxic metals, including lead, aluminum, cadmium and mercury.
However, the amounts of these toxic elements in eggshells are lower than in other natural sources of calcium, such as shellfish.
Appropriate quantity and reserves of experts
About 2.5 grams of egg pods are enough to cover the daily calcium needs of an adult. For added safety, you should moderate your intake of homemade calcium supplements.
Some experts do not like the regular consumption of calcium supplements and even question the health benefits of the bones. These experts worry that an excessive intake of calcium can cause health problems, such as kidney stones, and potentially increase the risk of heart disease.
