Eating too much egg yolk can lead to dyslipidemia, fatty liver, indigestion, abnormal liver and kidney functions. Egg yolks are extremely nutritious, which are rich in cholesterol, fat, protein and other nutrients. Consuming too much egg yolk will lead to excessive cholesterol in the body that cannot be digested, resulting in hypercholesterolemia. At the same time, egg yolks also contain a lot of fat. Undigestible fat deposited on the walls of blood vessels will form hyperlipidemia and blood clots clogging blood vessels, and even the formation of fatty liver. The protein content in egg yolk is also high. The liver is the main organ for protein synthesis and metabolism, and its metabolites are excreted by the kidneys. Therefore, excessive consumption of egg yolks may lead to indigestion and aggravate the burden on the liver and kidneys. It is recommended to consume 1 to 2 eggs a day to ensure nutrient intake and to prevent adverse effects caused by overconsumption.
