The Omnivore's Brain Analysis

Decent Essays

And then in the section, “The Omnivore’s Brain” the author explains how our varied diet plays a role in why our brains work more efficiently than that of other animals, and how our brains are part of the cause of this dilemma. The omnivore’s dilemma wasn’t always a necessarily “bad” thing. In fact, it was said to be one of the reasons of why our brains are so large. Koalas do not require as much of brainpower, as we do, in order to determine what food to eat, since it only eats one type of food. That is why their brains barely fill up its skull. In fact, zoologists “think the koala once ate a more varied diet than it does now. As it evolved toward eating just one food, it didn’t need to think as much. Over generations, unused organs tend to …show more content…

And how instinct isn’t always something that we could solely rely on, unlike other animals. All humans have a built-in signal inside of them that guides them towards what to eat and what to avoid. The taste that is called bitter tells us to stop eating a certain type of food. This is good for most cases. For example, plant toxins, which are poisons, are bitter. Avoiding toxins is possible by trusting our instincts and avoiding bitter food. But, bitter isn’t always bad. In fact, it “turns out that some of the bitterest plants contain valuable nutrients, even useful medicines. We can’t only rely on our sense of taste when we choose what we eat” (Pollan 89). An example is of broccoli. Broccoli is a taste that many people actually enjoy, despite it being bitter. And is also actually very healthy. Another example is of how early humans had learned to make tea from the bark of the willow tree because it contained salicylic acid, a pain reliever. It proves to show how our “food choices ae not just dictated by instinct. We can learn to eat bitter foods if they are good for us. We sometimes even decide that we like them” (Pollan 89-90). Although instinct is one of the very crucial traits to survival, it isn’t really something that we could solely rely on for us to get by. And that is why we also rely on our brains to make better and more informed decisions. For example, through cooking, we have managed to overcome to bitterness of some plants. With a variety of techniques and methods, we have found ways to make otherwise harmful food safe to eat. As cooking was discovered, it immediately became one of the most important tools that a human omnivore uses. Not only does cooking increase the type of plants and animals that we could eat, but it was also the turning point in human evolution. In fact, “Anthropologists think early primates (pre-humans) learned how to use fire
