Meat has played an important role in the human nutrition for the past 2.5 million years and has greatly influenced human evolution. It is an excellent source of high-quality protein and many vitamins and minerals with high bioavailability. However, nowadays meat is often considered harmful to human health, although this evidence is based on epidemiological studies with many flaws. There is also no known compound or mechanism that would make meat dangerous to human health. The negative impact of animal husbandry on the environment is also often highlighted, although on closer examination, the environmental impact is exaggerated and meat may actually play an important role in green transition. Over the past 200 years, the vegan movement has gained strong momentum, while growing middle-class income inequality, media attention to food safety, and climate change have helped the Planetary Health Diet (PHD) grow in popularity, this diet allows a maximum of 14 grams of red meat and 29 grams of poultry per day. The Eat-Lancet Commission is attempting to implement this diet into global food policy through a strong strategic network of relationships and numerous repressive methods. However, the PHD is based on unreliable epidemiological studies, flawed and unrepeatable calculations, and focuses exclusively on the problems of countries with a higher socio-demographic index. The PHD is thus a product of economic, ideological, and cultural interests, which are also increasingly being incorporated into the creation of general dietary guidelines. Therefore, we must strive for greater objectivity and scientific justification in the formation and implementation of dietary guidelines in the future.
