Natural Yogurt in gelato
Natural yogurt is plain, unsweetened whole-milk yogurt: fermented milk that is about 88% water and 12% solids (milkfat, protein, lactose and minerals). In gelato it adds fresh acidic tang, light body from milk solids, and a small anti-freezing contribution from lactose.

Natural yogurt is the base of frozen-yogurt and yogurt gelato, prized for its lactic acidity that lifts fruit and cuts richness. Because it is ~88% water it dilutes the mix, so recipes usually pair it with milk powder, cream or extra sugar to rebuild total solids and body. Its only sugar is lactose, a weak sweetener (POD ~16) but a strong per-gram cryoscopic agent (PAC ~100, like sucrose), so it contributes little sweetness while nudging PAC up modestly and softening the scoop. The protein and calcium improve body and whipping; the acidity can help perceived freshness but excess can make texture grainy if MSNF runs high. Add after the base is pasteurised/cooled to preserve tang and live cultures.
Origin & background
Fermented milk dates back thousands of years across Central Asia, the Middle East and the Balkans; the English word comes from the Turkish root meaning to thicken or condense. Yogurt reached Western popularity in the early 1900s after Nobel laureate Elie Metchnikoff's 'The Prolongation of Life' (1908) linked Bulgarian yogurt's lactic bacteria to longevity.
