Does eating red meat increase the risk of dying from heart disease or cancer? It’s a question that keeps coming up, fueled by research and high-profile campaigns by advocacy groups on both sides of the debate.
The following are some answers about disease risk, health benefits, and what role red meat should play in the diet.
For heart disease, the answer is pretty clear. Some red meats are high in saturated fat, which raises blood cholesterol. High levels of LDL cholesterol increase the risk of heart disease. When it comes to cancer, the answer is not as clear, depending on who you ask.
Many researchers say they do raise the risk, especially for colorectal cancer.
A recent study of more than a half-million older Americans concluded that people who ate the most red meat and processed meat over a 10-year-period were likely to die sooner than those who ate smaller amounts.
Those who ate about 4 ounces of red meat a day were more likely to die of cancer or heart disease than those who ate the least, about a half-ounce a day.
The meat industry contends there is no link between red meat, processed meats, and cancer, and says that lean red meat fits into a heart-healthy diet.
But many studies have found similar links. Another one that followed more than 72,000 women for 18 years found that those who ate a Western-style diet high in red and processed meats, desserts, refined grains, and French fries had an increased risk of heart disease, cancer, and death from other causes. The connection between consumption of red and processed meats and cancer, particularly colorectal cancer, is very consistent.
That’s not clear, but there are several areas that researchers are studying, including:
• Saturated fat, which has been linked to cancers of the colon and breast as well as to heart disease.
• Carcinogens formed when meat is cooked.
• Heme iron, the type of iron found in meat, may produce compounds that can damage cells, leading to cancer.
Red meat is high in iron, something many Black women are deficient in. But, iron can be found in
many vegetables, but the heme iron in red meat is also easily absorbed by the body.
Red meat also supplies vitamin B12, which helps make DNA and keeps nerve and red blood cells healthy, and zinc, which keeps the immune system working properly. Red meat also provides protein, which helps build bones and muscles.
It’s red meat, according to the U.S. Department of Agriculture. The amount of myoglobin, a protein in meat that holds oxygen in the muscle, determines the color of meat. Pork is considered a red meat because it contains more myoglobin than chicken or fish.
Opinions differ here, too. Most nutritionists suggest focusing on sensible portion sizes and lean red meat cuts, for those who choose to eat it.
Ask yourself these questions:
• Are you taking in more calories than you’re burning off?
• Is red meat crowding out foods such as fruits, vegetables, and whole grains?
Government guidelines suggest 5 to 6 1/2 ounces daily of protein from a variety of sources, including lean meats, nuts, and seafood. So if you’re planning on eating a burger for dinner, it should be a 3-ounce hamburger patty, about the size of a standard fast-food burger.
Try to eat no more than 18 ounces of cooked red meat a week. You should avoid all processed meats, such as sausage, deli meats, ham, bacon, hot dogs, and sausages, as research shows an increased risk of colon cancer from consumption.
6. What are some of the leanest cuts of red meat?
For the best red meat cuts, look for those with “loin” in the name: Sirloin tip steak, top sirloin, pork tenderloin, lamb loin chops.
• Beef: Also look for
round steaks and roasts, such as eye round and bottom round; chuck shoulder steaks; filet mignon; flank steak; and arm roasts. Choose ground beef labeled at least 95% lean.
Frozen burger patties may contain as much as 50% fat; check the nutrition facts box. Some grilling favorites are high in fat: hot dogs, rib eyes, flat iron steaks, and some parts of the brisket (the flat half is considered lean).
• Pork: Lean cuts include loin roasts, loin chops, and bone-in rib chops.
7. What are the criteria for a lean cut of red meat?
Meats can be labeled as lean if a 3-ounce serving contains less than 10 grams of total fat, 4.5 grams or less of saturated fat, and less than 95 milligrams of cholesterol.
If you’re buying beef, check the U.S. Department of Agriculture grading, too. Beef labeled “prime” is the top grade but is also highest in fat, with marbling, tiny bits of fat within the muscle, adding flavor and tenderness.
Most supermarkets sell beef that is graded as “choice” or “select.” For the leanest red meat, look for a select grade.
8. Is grass-fed beef a leaner red meat choice than grain-fed?
Grass-fed beef is leaner than grain-fed, which makes it lower in total fat and saturated fat. Grass-fed beef also contains more omega-3 fatty acids.
But the total amount of omega-3s in both types of beef is relatively small. Fish, vegetable oil, nuts, and seeds are better sources of omega-3s.
9. Can grilling red meat cause cancer?
High-temperature cooking of any muscle meat, including red meat, poultry, and fish, can generate compounds in food that may increase cancer risk. They’re called heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs).
10. How can you reduce potential cancer-causing compounds when grilling?
Several steps help prevent these compounds from forming or reduce your exposure to them.
• Choose lean red meat cuts when grilling to reduce the chance of flare-ups or heavy smoke, which can leave carcinogens on the meat.
• If grilling, cook over medium heat or indirect heat, rather than over high heat, which can cause flare-ups and overcook or char meat. Limit frying and broiling, which also subject meat to high temperatures.
• Don’t overcook meat. Well-done meat contains more of the cancer-causing compounds. But make sure that meat is cooked to a safe internal temperature to kill bacteria that can cause food-borne illnesses. For steaks, cook to 145 to 160 degrees Fahrenheit; for burgers, cook to 160 degrees.
• Marinate. Marinades may reduce the formation of HCAs. Choose one without sugar, which can cause flare-ups and char the meat’s surface.
• Turn meat frequently. Use tongs or a spatula rather than a fork to avoid releasing juices that can drip and cause flare-ups. Do not press burgers with a spatula to release juices.
• Don’t grill as much meat. Instead of a steak, try a kabob that mixes meat, fruit and vegetables. Plant-based foods have not been linked to HCAs.
• Trim fat from meat before cooking, and remove any charred pieces before eating.
• Consider partially cooking meats and fish in the oven or microwave before finishing on the grill.
So what’s the answer? People who eat less red meat have been known to live longer. Notice, we didn’t say NO red meat, we said less. It’s proven and has been in research study after research study, so you make your own decision on that.
