By Amanda Gardner

Eating an excessive amount of crimson meat has lengthy been a no-no for individuals with excessive ldl cholesterol and different threat components for coronary heart illness. But it hasn’t at all times been clear how a lot is an excessive amount of.

Now, a brand new examine means that you do not have to chop out crimson meat altogether to enhance your coronary heart well being. If you eat crimson meat greater than as soon as a day, reducing again to at least one serving each different day can considerably cut back your threat of getting a coronary heart assault or dying from coronary heart illness, the examine discovered.

Replacing the crimson meat in your food regimen with different, much less fatty sources of protein—equivalent to nuts and fish—can decrease your threat even additional, the researchers say.

Women who eat two servings of crimson meat per day have a 30% elevated threat of coronary heart illness in comparison with ladies who common three to 4 servings per week (or half a serving per day), based on the examine, which seems within the journal Circulation.

That’s a “pretty dramatic increase,” says the lead researcher, Adam Bernstein, MD, a analysis fellow within the division of vitamin at Harvard School of Public Health, in Boston. Although the examine included solely ladies, Dr. Bernstein says he would anticipate the findings to be related in males.

The examine gives a very good overview of how crimson meat consumption can have an effect on coronary heart well being, says Suzanne Steinbaum, DO, the director of ladies and coronary heart illness at Lenox Hill Hospital, in New York City.

“This gives you an understanding of what moderation means,” says Steinbaum, who was not concerned within the new analysis. “It gives you something to grab onto.”

Some varieties of crimson meat seem like worse on your coronary heart than others. Eating one serving of beef per day solely will increase a lady’s heart-disease threat by about 8%, in comparison with consuming it by no means or hardly ever. But consuming one hamburger, one serving of bacon, or one sizzling canine per day ups a lady’s threat by 42%, 41%, and 35%, respectively, in comparison with consuming these meals a few times a month (if ever), based on the examine.

The saturated fats in meat might solely be partly responsible. Iron and different minerals present in crimson meat might contribute to heart-disease threat as properly, Dr. Bernstein says. (Consuming high-fat dairy objects—equivalent to ice cream, bitter cream, and butter—additionally elevated the danger of coronary heart illness within the examine, however much less so than crimson meat.)

Dr. Bernstein and his colleagues adopted roughly 85,000 middle-aged ladies for a median of 26 years, throughout which era 2,210 of the ladies had coronary heart assaults and 952 died from coronary heart illness. The ladies had been all nurses, and had been a part of a long-running examine on well being behaviors that included prolonged food regimen questionnaires given each 4 years. To zero in on the hyperlink between food regimen and coronary heart well being, the researchers took under consideration different well being components, equivalent to physique mass index, smoking, alcohol consumption, and train.

Replacing crimson meat with more healthy sources of protein will go a good distance towards lowering coronary heart threat, the researchers say.

For occasion, they estimate that swapping one serving of crimson meat per day for one serving of beans will decrease a lady’s long-term heart-disease threat by about one-third. Replacing a every day serving of crimson meat with one in every of a number of different meals—together with nuts (30%), fish (24%), rooster or different poultry (19%), and low-fat dairy (13%)—may also cut back heart-disease threat, the examine discovered.

Though these are estimates, they symbolize the primary time that researchers have been in a position to quantify the center advantages of those meals swaps.

“We know that red meat is not as good as other protein sources,” says Karen Congro, a registered dietitian on the Brooklyn Hospital Center, in New York City. “Now we actually have the numbers to put next to them.”

The examine “doesn’t mean that red meat is a horrible thing,” says John Bisognano, MD, the director of outpatient cardiology on the University of Rochester Medical Center, in N.Y. “People like to eat, and all you can hope to do is shift them a little bit away from foods that may have less of a benefit to them to those that have more of a benefit to them.”
