Is meat really a bad food?



Even people who say 'meat is a staple food!' Are concerned about the impact of meat on health. Kurzgesagt, a science-based YouTube channel, explains in an animation the question 'Is meat eating bad for health?'

Is Meat Bad for You? Is Meat Unhealthy?-YouTube


About two million years ago, the ancestors of humanity who ate only plants began to eat meat from need.


The reason is that plants are greatly affected by climate change and often can not be harvested.


It has been since the discovery of fire that meat has become a major part of daily diets.


However, in the past few years, eating meat has been said to be largely associated with heart disease, certain types of cancer, and short lives.


In fact, what is the impact of meat on health?


Biologically, there are three reasons why the human body needs meat.


The first is as an energy source. The second is to feed the nutrients that are the source of cells. The third is to obtain molecules that can not be generated in the body.


Fats, carbohydrates and proteins are the sources of energy and the source of cells.


Molecules that the body can not produce are numerous vitamins and minerals.


Meat contains most of the fat, carbohydrates, proteins, vitamins, and minerals needed by the body.


There are also nutrients that are hardly contained in vegetables, such as vitamin B12 .


Among the nutrients not contained in meat, only vitamin C is essential to our bodies. Vitamin C is a nutrient that helps the body's immune system work properly and is found in almost all plants.


If you do not take vitamin C for several months, you will get scurvy , so you also need vegetables.


Another great advantage of meat is that some nutrients are more quickly digested and absorbed from meat than from vegetables.


Spinach, for example, contains more iron than meat, but it is slow to digest and absorb and requires more energy to digest.


As mentioned above, meat itself is not dangerous to humans.


However, the actual impact that meat has on health depends on how the meat was cooked and what it is.


The healthiest thing in animals is probably fish.


Fish contain unsaturated fatty acids such as omega-3 fatty acids that reduce the risk of cardiovascular disease and have anti-inflammatory effects on immune function.


No need to worry about eating fish regularly.


On the other hand, the fishery has various problems such as overfishing and marine pollution.


The second place behind the fish is chicken.


Chicken is said to be the most healthy of all meat.


The only problem with chicken is 'fat'.


Fat is related to blood total cholesterol levels and cardiovascular diseases.


However, the question 'whether total cholesterol is related to fat intake or genetics more strongly' has not been settled yet.


Anyway, if you care about health when eating meat, you should use chicken.


On the other hand, health problems begin to appear when you eat a lot of red meat , which is raw meat such as beef, pork, lamb, horse meat and lamb.


According to a recently published study , the recommended daily intake of red meat is quite low at only 23 g.


According to the meta-analysis that integrated analysis of a large number of studies, eating 100 grams of red meat a day ...


The risk of stroke is increased by 11%, diabetes by 19%, and rectal cancer by 17%.


Although it may seem quite dangerous to eat red meat if you ask about this, let's take a closer look at 'meal research methods' before you panic.


Most of the research on eating red meat is a case-control study in which people who have the disease in question are interviewed about their eating habits and the results are classified.


The problem with this research method is that it is difficult to consider factors other than eating habits.


People who say 'does not eat too much meat' live a healthier life, eat more vegetables and fruits, and tend to have lower smoking and drinking rates. These and other 'other factors' in the eating habits affect health, but it is unclear which ones affect health.


Of course, researchers are making efforts to eliminate 'other factors', but the situation is quite difficult.


There is also the question of whether the meat has been processed.


In order to improve the taste of processed meat, additives harmful to the human body are used in the process of food processing.


Nitrate and nitrite damage DNA in the human digestive system and cause cancer.


The World Health Organization (WHO) has reviewed 800 studies in the last 20 years and concluded that processing wheat used for sausages etc. is strongly associated with the risk of rectal cancer.


If you eat 50g more processed meat every day, the risk of cancer will increase by 18%.


Processed meat increases the risk of stroke by 13%, diabetes by 51% and heart disease by 42%.


If you eat large amounts of both red meat and processed meat, the risk of dying under the age of 75 increases by 29%.


This means that if you have a 3% risk of dying this year, eating meat will give you a 4% risk of dying.


It may not seem like a big difference, but considering the society as a whole, the number of dead will increase dramatically.


There is no evidence that the meat itself contains 'unhealthy sources' other than fat. There is also ongoing debate about whether fat is unhealthy.


It is worth noting that passing by is like eating meat and other enjoyable things.


Most sanitation agencies use meat up to 500g a week. However, recent studies suggest that processed meat should not be eaten.


If you can avoid eating a lot of meat once or twice a week, it's probably okay ...


The average American consumes 1600 grams of meat a week, and it requires major change.


If you don't know how much you don't eat meat, it's a good idea to take notes when you eat meat.


Then you will notice how much you are eating meat.


Consuming meat is not only a health problem. Livestock production has a significant impact on climate change, and there are also issues related to animal rights .


In conclusion, if you eat moderately, the meat is not unhealthy, so you don't have to turn into a vegetarian overnight.


But deciding on your lifestyle is important for yourself and for others.


The key is that 'sometimes try something new'. Some things that have never been eaten may also be delicious.


Until you try it, you do not know what you can do or what it is fun for you.
