Synopsis
Source of validity: Scientific
Rating (out of 5): 3
Eggs, particularly the egg shell and yolk, have a scientific basis for supporting the skeletal system due to their nutrient content. Eggshells are a natural source of calcium carbonate, a compound that is vital for bone health and commonly used in dietary calcium supplements. Scientific studies have demonstrated that eggshell powder can effectively increase bone mineral density and improve bone strength, especially in populations at risk of osteoporosis. Additionally, eggs provide vitamin D (mainly in the yolk), which aids in calcium absorption, as well as small amounts of phosphorus and protein—both of which play roles in bone metabolism and maintenance. However, most of the research supporting eggs for bone health centers around eggshell-derived calcium supplements rather than consuming whole eggs. While the calcium content of eggshells is high (about 95% calcium carbonate), eating raw or inadequately prepared eggshells is not recommended due to contamination risk and potential digestive irritation; commercially processed eggshell powders are considered safe. Overall, while there is moderate scientific evidence (hence a rating of 3) supporting the use of eggshells as a supplemental calcium source for bone health, whole eggs are not a significant direct source of calcium but contribute to skeletal health through their vitamin D and protein content.
