The Omnivore’s Dilemma-The Third Week

why would we have dessert even when we are sated?   

---

Our appetite for sweet things persists , which is probably why dessert shows up in the meal when it does. A sweet tooth represents an excellent adaptation for an omnivore whose big brain demands a tremendous amount of glucose (the only type of energy the brain can use),or at least it once did, when sources of sugar were few and far between.(The adult human brain accounts for 2percent of our body weight but consumes 18percent of our energy,all of which must come from a carbohydrate.Food faddists take note two.)

I remember my grandpa is  a hunter and really good one he knows how to use a gun and even knows how to make a gun. He uses different bullets for different prey small bullets for wild chickens and ducks while big one for wolves or deers. For black bears bullets can not kill them good hunter will prepare amazing trap for them. I still remember every time when my grandpa went to the forest he would wear his jacket which made by wolf skin.Grandpa has bees produce honey, so we don’t buy honey in the shops . Grandpa knows kill chickens without any suffering (they will die immediately).But after he passed away we almost buy everything from the shops and no one in our family can use a gun or knows how to make a gun. Grandpa knows how to survive in the mountains for months but we don’t know anymore. -weird dilemma.
