Meat has nutritional value, but there are dangers in eating too much red and processed meats.
The majority of people around the world receive their vital nutrients from meat. More specifically, pork is the most widely eaten meat in the world. It makes up 36 percent of global meat consumption. Poultry comes in second, at a close 35 percent, and beef stands at 22 percent.
Amazingly, in 2018, the world produced a record high of well over 200 pounds of red meat and poultry per person. The volume of chicken produced globally has grown five-fold since 1970. Clearly, we’re eating a lot of meat. But that may not be a good thing for our health – or for the planet.
The key message here is: Meat has nutritional value, but there are dangers in eating too much red and processed meats.
Meat provides us with essential nutrients like zinc, various forms of vitamin B, riboflavin, iron, and, of course, protein. Calorie-wise, pork comes out on top with 310 calories for a standard three-ounce portion. It is followed by beef at 245 calories, lamb at 235, goat at 122, and chicken at 120 calories.
So is meat part of a healthy diet? Well, it depends on the sort of meat you consume and how much of it ends up on your plate. An excess of red meat – which includes beef, pork, veal, lamb, goat, and mutton – can be a problem. The same goes for processed meats like smoked bacon or salami.
Processed meats generally contain lots of salt, sugars, and preservatives. And smoked meat products, as well as meat grilled over high heat, have been proven to contain carcinogenic substances.
But even though processed meat isn’t the healthiest of foods, it’s a popular element of many Western diets. And this means that it’s been heavily researched. In 2014, experts from around the world reviewed over 800 studies and confirmed that there is a link between eating processed meat and having a greater risk of cancer.
Their analysis found that eating as little as 50 g of processed meat every day increased the risk of colorectal cancer by 18 percent. As for red meat, experts agreed that a daily intake of 100 g increased the risk of colorectal cancer by 17 percent.
Scientists are studying cooking methods as well. And there are also some researchers who are looking at correlations between red meat and stomach or prostate cancer.
That research is ongoing, but it’s safe to say that many Western diets do include too much red meat. By cutting back a bit, you can make sure that the nutritional benefit of meat isn’t outweighed by the risks. - source: Blinklist Book Summary
