ults who ate about 1 ½ eggs daily h a slightly higher risk of heart disease than those who ate eggs. study showed more eggs, greater risk. chances of dying early were also elevated.

researchers say culprit is cholesterol, found in egg yolks and or foods, including shellfish, dairy products and red meat. study focused on eggs because y’re among most commonly eaten cholesterol-rich foods. y can still be part of a healthy diet, but in smaller quantities than many Americans have gotten used to, researchers say.
U.S. dietary guidelines that eased limits on cholesterol have helped eggs make a comeback.
study has limitations and contricts recent research, but is likely to rekindle long-standing debate about eggs.

STUDY

Researchers at rthwestern University’s Feinberg School of Medicine and elsewhere pooled results from six previous studies, analyzing data on almost 30,000 U.S. ults who self-reported daily food intake. Participants were followed for roughly 17 years, on aver.
researchers calculated that those who ate 300 milligrams of cholesterol daily — about 1 ½ eggs — were 17 percent more likely to develop heart disease than whose who didn’t eat eggs.

researchers based ir conclusions on what participants said y ate at start of each study. y took into account high blood pressure, smoking, obesity and or traits that could contribute to heart problems. Risks were found with eggs and cholesterol in general; a separate analysis was t done for every cholesterol-rich food.
Dr. Bruce Lee of Johns Hopkins University, said nutrition studies are often weak because y rely on people remembering what y ate.
“We kw that dietary recall can be terrible,” said Lee. new study offers only observational data but doesn’t show that eggs and cholesterol caused heart disease and deaths, said Lee, who wasn’t involved in research.

Senior author rrina Allen, a preventive medicine specialist, ted that study lacks information on wher participants ate eggs hard-boiled, poached, fried, or scrambled in butter, which she said could affect health risks.
Some people think ‘“I can eat as many eggs as I want’” but results suggest moderation is a better approach, she said.
DEBATE
Eggs are a leing source of dietary cholesterol, which once was thought to be strongly related to blood cholesterol levels and heart disease. Older studies suggesting that link led to nutrition guidelines almost a dece ago that recommended consuming more than 300 milligrams of cholesterol daily; one egg contains about 186 milligrams.
Newer research questioned that relationship, finding that saturated fats contribute more to unhealthy levels of blood cholesterol that can le to heart problems.
latest U.S. government nutrition guidelines, from 2015, removed strict daily cholesterol limit. While eating as little cholesterol as possible is still vised, recommendations say eggs can still be part of a healthy diet, as a good source of protein, along with lean meat, poultry, beans and nuts. Nutrition experts say new study is unlikely to change that vice.
BOTTOM LINE
Dr. Frank Hu of Harvard University ted that most previous studies have shown that eating a few eggs weekly is t linked with risks for heart disease in generally healthy people.
“I don’t think that this study would change general healthy eating guidelines” that emphasize fruits, vegetables, whole grains, nuts and beans and limiting processed meats and sugar, Hu said. Eggs, a breakfast staple for many, can be included but or options should also be considered, “like whole grain toast with nut butter, fresh fruits, and yogurt,” Hu said.
Dr. Rosalind Coleman, a professor of nutrition and pediatrics at University of rth Carolina, offered broer vice.
“ main mess for public is t to select a single of food as ‘b’ or ‘good’ but to evaluate your total diet in terms of variety and amount.
“I’m sorry if it seems like a boring recommendation,” she ded, but for most people, most important diet vice “should be to maintain a healthy weight, to exercise, and to get an equate amount of sleep.”
