תְּזוּנָה (Tzuna) — nutrition

Etymology

The word tzuna was coined by Yitzhak Epstein, a prominent Hebrew educator and linguist. Born in Belarus in 1862, Epstein immigrated to Israel in 1886. He was a prolific innovator of Hebrew terms, many of which—including zehut (identity), toda'a (consciousness), and tatzpit (observation)—remain central to the language today. Tzuna is built from the root זו״ן (Z-V-N), the same root that provides the ancient word mazon (food). This development allowed Hebrew to distinguish between sustenance itself and the broader concept of nutrition.

The wider vocabulary of nutrition, known as avot hamazon (macronutrients), was developed through the early 20th century. For instance, the word pachmema (carbohydrate) was coined by Meir Winnik in 1928 as a calque of the German Kohlenhydrat. Winnik also introduced terms for chemical elements such as ashlegan (potassium) and zarchan (phosphorus).

Other nutritional terms were repurposed from ancient sources. Chelbon (protein) originally referred to the "egg white" in the Talmud, but was adopted as the Hebrew equivalent of "protein" in the 20th century, following the German linguistic model (Eiweiß). Similarly, shuman (fat) evolved from the Mishnaic shomen, while amilan (starch) was a Greek loanword dating back to the Mishnaic period.
