It is said that the more people eat walnuts, the smarter they become, because the structure of walnuts is similar to that of human brains. No matter from the grain or the surface separation, they are very similar to human brains. It is a legend in China that walnuts should be called smart fruits.

As for pine nut, I personally think it can be called stupid fruit, because the fruit of pine nut is a solid fruit, just like a person's brain doesn't understand, there is no clear idea and line, which is just a moral.

Up to now, there is no data to show whether people become smart or clumsy after eating these fruits. I think that no matter what the names of these fruits are, the key is to eat more if you are willing to eat, and eat less if you are unwilling to eat. A person's cleverness and clumsiness can be changed not by eating these things. If you want to be smart, you need to use your brain more. The more you use your brain, the more flexible it is. Even if you don't use your brain for a long time, you will become dull.
