The news headlines were everywhere: "It's Okay to Eat Red Meat." The source for this statement was a study published online Oct. 1, 2019, in Annals of Internal Medicine.

The study and its widespread reaction have once again brought up the question of whether red meat and processed meat are bad for your health and if people should cut them out or simply cut back.

"The evidence shows that people with a relatively low intake have lower health risks," he says. "A general recommendation is that people should stick to no more than two to three servings per week."

For processed meat, Dr. Hu says there is a much stronger association with a higher risk of heart disease and cancer (especially colon cancer).

Unsurprisingly, the backlash from the science community was sharp and swift. For instance, Harvard's T.H. Chan School of Public Health issued a statement that the new advice could potentially harm people's health.

Dr. Hu suggests that people focus not so much on actual serving sizes, but rather on red meat's placement in meals. "Instead of the main course, use red meat as a side dish," he says. "Consider red meat a luxury and not a staple food.

But the key word here is "high." Dr. Hu points out that the exact amounts for safely consuming red meat are open to debate.

Our Caution Biological Hazard safety sign is a warning category sign conforming to the BS5499 standard. These health and safety signs are required by the Health and Safety (Safety Signs and Signals) Regulations 1996. A warning sign will appear as a black banded, yellow, equilateral triangle with the type of hazard picture in black, positioned centrally on the sign.

The biohazard symbol is used as a warning, so that those potentially exposed to harmful substances will know to take precautions.  It is used around biological materials that carry a significant health risk. The Caution Biological Hazard sign is available in a wide selection of footprints and materials including Dibond aluminium and foamex. You can find our full material guide here.

When ordering your safety sign you have the option of having it pre-drilled or backed with self-adhesive velcro striping for easy fixture.

Processed meat products contain high amounts of additives and chemicals, which may contribute to health risks. "Again, there is not a specific amount that is considered safe, so you should keep processed meat intake to a minimum," he says.

Some kinds of red meat are not necessarily healthier. There are no firm studies that have shown nutritional or health advantages from eating organic or grass-fed beef.

"These types of red meat are often more desirable as they contain low or no growth hormones compared with grain-fed beef, but it's still not clear if they offer any health benefits," says Dr. Hu.

You don't need to eat red meat. Red meat has high amounts of protein, which helps promote muscle growth, and vitamin B12 to make red blood cells. For example, a 3-ounce serving has about 45% of the Daily Value (DV) of protein and 35% of the DV for B12. A serving of red meat is also a good source of zinc, which can help the body produce testosterone, and selenium, a powerful antioxidant. Plus, red meat is rich in iron. However, Dr. Hu says that you don't need to eat red meat to get these essential nutrients. "You can get the same amounts — and in some cases even more — from poultry, fish, eggs, and nuts, and as well as by following a plant-based diet."

An international team of researchers conducted five systematic reviews that looked at the effects of red meat and processed meat on multiple health issues, such as heart disease, cancer, diabetes, and premature death.

Red and processed meats do increase health risks. In spite of what the Annals of Internal Medicine study suggests, Dr. Hu says that an accumulated body of evidence shows a clear link between high intake of red and processed meats and a higher risk for heart disease, cancer, diabetes, and premature death. "The evidence is consistent across different studies," he says.

"This new red meat and processed meat recommendation was based on flawed methodology and a misinterpretation of nutritional evidence," says Dr. Frank Hu, chair of the Department of Nutrition. "The authors used a method often applied to randomized clinical trials for drugs and devices, which is typically not feasible in nutritional studies."
