How to say "nuts" in Japanese

• ナッツ
  nounThe everyday word for nuts as food, such as almonds or walnuts. This is usually the word you want when talking about eating nuts or listing ingredients.
  私はレシピからナッツをはずした。デリアはナッツアレルギーだから。↗

  I've left out the nuts in this recipe because Delia's allergic to them.
• 種実類しゅじつるい
  nounA collective, technical term for nuts and seeds as a food category. It appears mainly in nutrition, dietary, or product-labeling contexts rather than casual conversation.
• 金玉きんたま
  nounA colloquial, coarse word for testicles; 'nuts' here is only in the slang sense. It is not used for edible nuts, and it is generally inappropriate in polite speech.
• 頭がおかしいあたまがおかしい
  expression, i-adjectiveA predicate phrase meaning someone is crazy or out of one's mind; 'nuts' here is figurative. Use it in sentences like saying a person's behavior is not right.
  あの老人ろうじんは頭あたまがおかしいにちがいない。↗

  That old man must be off his rock.
• 頭のおかしいあたまのおかしい
  expression, prenominal modifierThe attributive form of the same idea, modifying a noun directly, as in describing someone as a crazy person. It does not stand alone as a predicate.

For the food sense use 「ナッツ」 or the more technical 種実類; for 'crazy' use 「頭がおかしい」 or its attributive form 「頭のおかしい」; 金玉 is a vulgar colloquial word for testicles, not a food term.
