How to say "nutrition" in Japanese

• 栄養えいようJLPT N3approx.Common
  nounThe default word for 'nutrition': the nourishment a person or body gets from food, as in diet, health, and nutrition science. Use this unless you specifically mean the nutrients themselves.
  この魚さかなは安やすくてしかも栄養えいようがある。↗

  This fish is inexpensive but nourishing.
• 養いやしないCommon
  nounNourishment as sustenance — feeding and providing for someone, from the verb 養う 'to support, feed'. For 'nutrition' in the dietary or scientific sense this is seldom the word you want; think 'sustenance'.
• 滋養じようCommon
  nounCovers 'nourishment' more than 'nutrition': the rich, sustaining goodness of food. For talking about diet and health, 栄養 is the usual choice.
  カレーのルーは非常ひじょうに滋養じように富とんでいる。↗

  Curry sauce is very nourishing.
• 栄養分えいようぶんCommon
  nounThe nutrients themselves — the nourishing components contained in food. Use it when 'nutrition' means those substances rather than the general concept, for which 栄養 is the word.
  このビタミン剤びたみんざいは栄養分えいようぶんを豊富ほうふに含ふくんでいる。↗

  The vitamin pill contains abundant nutrition.

Choose 栄養 for nutrition in general, whether dietary or scientific; 栄養分 for the nutrients in food; 滋養 for rich, wholesome nourishment; 「養い」 is really 'sustenance, providing for someone' and seldom the word for 'nutrition'.
