◆ True 2: Red meat should be given priority

On the other hand, because preservatives contained in processed meat such as bacon, sausage and salami increase the risk of blood pressure, stroke and cancer, `` Eating processed meat, even if it is red meat, is high risk. '' Says Mozaffarian.
◆ True 3: 'Plant-based' meals should be eaten
Do not eat the food of animal origin vegan typified by vegetarians (vegetarianism) has been touted as the recent 'health of the pronoun'.

Cows described as `` grass fed '' eat and grow corn, soy, barley, cereals, etc. in addition to grass, and there is no significant nutritional difference between grass-fed and non-grassed meat. Research results are reported.
According to Professor Mozaffarian, 'You can choose grass fed beef for philosophical and environmental reasons, but it is wrong if you expect health benefits.'
◆ 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. However, Professor Mozaffarian points out that 'the effect of artificial meat on health remains uncertain.' Taking the example of Impossible Meat , a plant-derived artificial meat sold in the United States, heme iron, a large amount of salt, and genetically modified yeast are used, and their calories are not low.

◆ Fact 1: Processed meat is bad for health
Processed meat contains preservatives that are harmful to health. Even if typical ingredients such as nitrates and nitrites are listed as 'unused' as preservatives, they may actually contain fermented celery powder that is rich in nitrite, and the U.S. Food and Drug Administration A petition has been filed with the (FDA) requesting a 'prohibition of misleading labeling.'
Processed meat may also contain carcinogenic substances, such as sodium, nitrite, and heme iron, that are formed when baked or smoked. These harmful compounds affect not only your own health, but also the fetus if taken by pregnant women.

Most of the diet-related diseases have low intake of healthy foods such as fruits, nuts, seeds, beans, vegetables, whole grains, vegetable oils, seafood, yogurt, and salt, refined starch, and sugar. There are research results that are caused by consuming a large amount of 'super processed foods' and juices that contain a lot of such. This diet has a worse health effect than eating lean meat.

◆ Fact 3: Cattle livestock is destroying the environment
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 is about five times that of fish, dairy products, and chicken, about 20 times that of eggs, nuts, and legumes, and that of fruits, vegetables, and whole grains. The effect is 45 to 75 times. According to a report released by the United Nations in 2013 (PDF file) , 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 and Beyond Meat , which are engaged in the plant-based artificial meat business, both have their philosophy of 'reducing reliance on the livestock industry that generates 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. '' Fruits, nuts, vegetables, vegetable oils, and whole grains are the best for humankind and for the planet. '
