◆ True 5: Plant-derived artificial meat is healthier than ordinary meat
In recent years, "artificial meat" that reproduces "meat taste" by processing plant-derived ingredients has appeared.

Beef production has significant negative effects on the environment, including greenhouse gas emissions from cattle burps and water pollution from manure. The impact of beef production on the environment depends on the impact of fish, dairy products and chicken on the environment.About 5 timesThe effect is about 20 times that of eggs, nuts and legumes, and 45 to 75 times that of fruits, vegetables, and whole grains. Published by the United Nations in 2013(PDF file)reportAccording to the report, greenhouse gases emitted by livestock make up 15% of the total, half of which comes from beef production.
◆ Fact 4: Artificial meat derived from plants is environmentally friendly
Compared to beef production, the production of plant-based artificial meat requires only one-tenth the water and land, and also reduces greenhouse gas emissions by a factor of ten.
Impossible Meat, which develops plant-based artificial meat business,Beyond MeatHas set their philosophy to "reduce reliance on the livestock industry that produces greenhouse gases."
Fact 5: Many questions unanswered
Professor Mozaffarian says that many questions remain unanswered, such as “ Which preservatives are the most harmful '', “ What increases the risk of type 2 diabetes in red meat '', “ Effect of artificial meat derived from plants ''? I admit that. On top of that, from the research results already known, “ Eating red meat is limited to once or twice a week '' “ It is clear that plant-based artificial meat is good for the environment, but healthy I'm not sure if it is good.
