If you eat a good amount of eggs during the week, be aware. A study conducted at Northwestern University of Medicine (USA) published in the journal JAMA He says that people who ingested more eggs and dietary cholesterol had a higher risk of having cardiovascular problems that could lead to death.
"You need to control the amount of cholesterol consumed high in eggs and specifically in egg yolks," says study author Norrina Allen. "As part of a healthy diet, you should consume lower amounts of cholesterol. People who use less cholesterol have a lower risk of heart disease," he added.
One of the richest sources of dietary cholesterol is undoubtedly the egg yolk. A large egg has 186 milligrams of dietary cholesterol in the egg yolk. Other products, such as red meat, butter or whipped cream, also have a high content.
It has been debated for decades whether eating eggs is related to cardiovascular problems and death. Eating less than 300 milligrams of dietary cholesterol was the recommendation in the United States. UU until 2015. However, the latest dietary guidelines omitted a daily limit on dietary cholesterol. According to this study, the current recommendations should be revised.
Earlier studies showed that eating eggs increased the risk of cardiovascular disease. But these studies had a less different sample, shorter time and limited ability to adapt to other parts of the diet, Allen says. "Our study showed that if two people followed exactly the same diet and the only difference in diet was eggs, one could directly measure the effect of egg consumption on heart disease. We found that cholesterol regardless of source was associated with an increased risk for heart disease, "he said.
So far, it is not known whether dietary cholesterol, the one consumed through diet, is the main cause of the rise in blood cholesterol. The reason why a maximum limit is not set in the consumption of cholesterol is that only between 15 and 20% of the diet consumed cholesterol is absorbed by the intestine. The high cholesterol is produced by the endogenous cholesterol produced by our body itself from an excess of refined saturated fats and sugars.
In this study, taking 300 mg of cholesterol in the daily diet was shown to be associated with a 17% higher risk of cardiovascular event and 18% death. In addition, eating three to four eggs per week was associated with a 6% higher risk of vascular disease and a risk of 8% for any source of death.
So, should we stop eating eggs?
According to the study, people should keep a low cholesterol intake by avoiding eating, such as red meat eggs. However, the authors believe that these foods are not a good source of important nutrients. Instead, you can take egg whites or eat less eggs.
This work contradicts many earlier. The egg has been damaged as an egg yolk contains 200 mg of cholesterol, ie 71% of the daily recommendations. However, studies showed that it does not pose a risk. In addition, the consumption of 1 egg a day is very unlikely to increase cardiovascular risk in healthy people.
