There are many types of nuts, i will list here some of the best varieties. Note that this is all my opinion.
Almonds- The best nut, almonds are sweet, salty, and can be used in various nature trail snack mixes. Almonds are so good, they are one of the only nuts to get a candy based off of it! (Almond Joy)
Peanuts- A classic at carnivals, Peanuts are a great snack for running with.. They can be made into various things, such as Peanut Butter, and Giraffe feed. Don't feed all giraffes peanuts though.
Acorns- I'm not entirely sure if this can be called a nut, but they grow on tree's, so i consider them one. Acorns aren't the best to eat, but squirrels feast on them a lot. Acorns are also good for throwing at people.
Macadamia Nut- The second best nut, Macadamia's are rich in flavoring, and can be used as a good alternative to Almonds. They are also perfect for cookies, and other sweets, such as cake and pudding.
Grape Nuts- no. Just no.
Here is the second part if you want to read it.
