In recent years, there has been a growing trend towards vegetarianism and veganism, with many individuals adopting these diets for ethical, environmental, or health reasons. However, a group of scientists are now speaking out against what they describe as the "zealotry" pushing these diets, arguing that meat is crucial for human health.

The group of scientists, led by Dr. Frank Mitloehner of the University of California, Davis, argue that meat provides essential nutrients that cannot be obtained from a vegetarian or vegan diet. These nutrients include vitamin B12, iron, and zinc, which are vital for the proper functioning of the body.

While it is true that plant-based foods can provide some of these nutrients, they are often not as readily absorbed by the body as those found in meat. For example, the form of iron found in meat, known as heme iron, is much more easily absorbed by the body than the non-heme iron found in plant-based foods.

Furthermore, the group argues that meat provides a complete source of protein, containing all of the essential amino acids that the body needs. While it is possible to obtain these amino acids from a vegetarian or vegan diet, it often requires careful planning and combining of different plant-based foods to ensure that all of the essential amino acids are being consumed.

The scientists also point out that there is no evidence to suggest that a vegetarian or vegan diet is inherently healthier than a diet that includes meat. In fact, studies have shown that vegetarians and vegans may be at risk of certain nutrient deficiencies, such as vitamin B12 and iron.

Of course, it is important to note that not all meat is created equal. The group of scientists emphasizes the importance of choosing high-quality, sustainably-raised meat that is free from antibiotics and hormones. They also encourage individuals to consume a variety of different types of meat, including poultry, beef, and pork, to ensure that they are getting a range of essential nutrients.

However, the message from these scientists is clear: meat is crucial for human health, and the push towards vegetarian and vegan diets should not come at the expense of our health. While it is important to be mindful of the environmental and ethical implications of meat consumption, we should not overlook the important role that meat plays in a healthy diet.

While the trend towards vegetarianism and veganism may be motivated by a desire for ethical and environmental sustainability, it is important to remember that these diets may not be optimal for human health. As such, the group of scientists calling for an end to the "zealotry" pushing these diets is an important reminder to consider the nutritional value of the foods we eat and to prioritize our health above all else.
