“Your brain requires around 130 grams of glucose every day to ensure it operates smoothly. Energy from carbs is essential to your body’s function.”
Carbs are a subpar food for humans. The idea they would be “essential” to us is baloney (pardon the pun given that baloney is better than any carbs possible), if not borderline criminal considering the official guidelines still recommend them for diabete patients.
I would like to think we are just carnivores but we are not. We are Omnivores that lean towards being healthier on a majority of meat consumption.
Just try to survive without Vitamin C intake tat can only be found in fruits and vegetables. You can actually die from scurvy within a couple months.
“Vitamin C (ascorbic acid) is a very important nutrient for your body. It’s responsible for the development, growth and healing of your skin, bones and connective tissue. In addition, you need vitamin C for your blood vessels to function properly. Vitamin C helps maintain your teeth and gums. It helps your body absorb iron, which it needs to make red blood cells. Vitamin C also helps heal burns and other wounds.”
