The Role of Meat in Human Nutrition

• Our ancient vegetarian ancestors began eating meat approximately two million years ago due to necessity rather than taste. Climate change made plants less accessible, and meat became a stackable food source.
• Meat provides a significant amount of energy, materials, and specialized molecules that our bodies cannot produce themselves.
• The three macronutrients – fats, carbohydrates, and proteins – provide energy, materials, and specialized molecules. Proteins are essential for repairing and maintaining our body structures.
• Meat is the primary source of certain essential amino acids and minerals, some of which are scarce in plants, such as vitamin B12.
• Vitamin C, which is commonly found in plants, is essential for our immune system and the development of connective tissue. A deficiency in vitamin C leads to scurvy.
• Meat is more bioavailable than plant-based sources, making it easier for our bodies to absorb and utilize the nutrients.
• The Inuit community, which primarily consumes a meat-based diet, can thrive in extreme living conditions due to the complete nutritional value they obtain from consuming the entire animal.
• Meat is not inherently unhealthy but its health effects depend on how it is prepared and the source of the animal.
• In the Western world, muscle meat is typically consumed, which has a high nutritional density but lacks certain vitamins.
• Chicken is considered the healthiest type of meat due to its lower risk of negative health effects, although a small controversy exists regarding its fat content and potential contribution to higher cholesterol levels.
• Processed meats, such as bacon, sausage, salami, and hot dogs, contain additives like nitrates and nitrites that can damage DNA and contribute to cancer.
• An excessive intake of red meat, including beef, pork, lamb, mutton, and venison, can lead to various health issues. The American and German average weekly consumption is around 1600 and 1100 grams, respectively.
• If you're unsure about how much meat you should eat, it's recommended to eat no more than one serving per week or two per week. This is a significant change for the average American, who consumes around 1600 grams per week.
• Animation is the key to where we are today. There's a great new Skillshare class on using Adobe Illustrator for design by graphic designer Aaron Draplin. Skillshare offers thousands of lessons covering various subjects, including film and video editing, writing, design, and technology, and a Premium Membership costs only $10 per month. For the first 1000 Kurzgesagt viewers who use the link in the description, the first two months of Skillshare will be free.
