The latest US research on eggs is not easier for those who can not eat breakfast without them.
Elders who eat 1 ½ eggs every day There is a slight higher risk of heart disease than those who eat no eggs. The study showed more eggs, the greater the risk. The probability of dying early is also high.
Researchers say that the culprit is cholesterol, found in egg yolks and other foods, including shellfish, dairy products and red meat. The study focuses on eggs because they are among the common foods of rich cholesterol. They can still be part of a healthy diet, but in smaller quantities than many Americans have already taken, researchers say.
The study has limitations and contradicts recent research, but it is likely to resume long debate about eggs.
The new result Was published on Friday in the Journal of the American Medical Association.
Researchers at the Feinberg School of Medicine of Northwestern University and elsewhere have developed results from six prior studies, analyzing data on nearly 30,000 people old US who reports on daily food intake. The participants followed for about 17 years, on average.
Researchers estimate that eating 300 milligrams of cholesterol daily – about 1 ½ eggs – is 17 percent more likely to have heart disease than those who do not eat eggs.
Researchers are based on their conclusions as to what participants say they ate at the beginning of each study. They recognize high blood pressure, smoking, obesity and other features that can contribute to heart problems. The dangers are found with eggs and cholesterol in general; A separate study was not made for every rich food of cholesterol.
Dr. Bruce Lee of Johns Hopkins University, says nutrition studies are often weak because they rely on people who remember what they eat.
"We know that dietary recuperation can be terrible," Lee says. The new study offers only observation data but does not show that eggs and cholesterol cause heart disease and death, Lee said, not involved in research.
Norrina Allen, a specialist in preventive medicine, study is lacking in information if participants eat eggs fried, fried, fried, or smoked in butter, which he said could affect the risks to health.
Some people are thinking "I eat as many eggs as I do not" The results indicate moderation is a better strategy, he said.
Eggs are a leading source of dietary cholesterol, once thought to be strongly associated with blood cholesterol levels and heart disease. Longer studies suggest that the link that leads to nutritional guidelines is almost a decade ago that recommended no more than 300 milligrams of cholesterol daily; An egg contains approximately 186 milligrams.
The new research has asked that relationship, in determining that fat hearts contribute more to the unhealthy levels of blood cholesterol that can lead to heart problems.
strict daily cholesterol limit. While eating a little cholesterol as long as it is still advisable, recommendations suggest that eggs can still be part of a healthy diet, as a great source of protein, along with lean meat, chicken, beans and nuts. Nutrition experts say that a new study is unlikely to change that advice.
Dr. Frank Hu of Harvard University said earlier studies have shown that eating a few eggs weekly is not linked to the risk for heart disease in general a healthy person.
"I do not think that this study will change the overall healthy diet guidelines" which emphasizes fruits, vegetables, whole grains, peanuts and beans and limits the processed meat and sugar, Hu said. Eggs, a breakfast for many, may be included but other options should also be considered, "like whole grains of noodles with butter, fresh fruit, and yogurt," says Hu.
Dr. Rosalind Coleman, a professor of nutrition and pediatrics at the University of North Carolina, offers greater advice.
"The main message for the public does not choose a kind of food as & # 39; bad & # 39; or & # 39; good & # 39; but to check your total diet in terms of others & # 39; "I'm sorry if it seems like a boring recommendation," he adds, but for the majority of people, the most important diet advice "should maintain a healthy weight, exercise, and Get enough sleep value.
