A vertically formatted, print-grade nutritional comparison infographic poster with a strict vertical half-and-half layout, where the canvas is divided into left and right sections by a straight line running down the exact center. At the top of the canvas, centered and spanning both halves, is a prominent large uppercase bold sans-serif headline reading 'COLA VS SPARKLING WATER,' with a smaller subtitle beneath it reading 'NUTRITION FACTS BATTLE.' The left half features a gradient background from dark red to bright red. In the upper-center of the left side is a flat-style illustration depicting a classic red aluminum can alongside a glass filled with ice cubes and dark cola, with a straw inserted in the glass. Below the illustration is white bold text reading 'COLA.' Beneath the text, detailed nutritional data is arranged vertically, each item accompanied by a minimalist white line icon: text reading 'Calories: 140 kcal' with a flame icon, text reading 'Sugar: 39g' with a stacked sugar cubes icon, and a smaller ingredient description reading 'Ingredients: Carbonated water, high fructose corn syrup, caramel color, phosphoric acid, caffeine.' At the bottom of the left half are three white-bordered tags reading 'High Sugar,' 'Artificial Additives,' and 'Energy Spike.' The right half features a gradient background from dark blue to light blue. In the upper-center of the right side is a flat-style illustration echoing the left side, depicting a streamlined transparent glass bottle alongside a glass containing clear water, dense bubbles, fresh lemon slices, and green mint leaves. Below the illustration is white bold text reading 'SPARKLING WATER.' Beneath the text, nutritional data is arranged vertically, aligned to match the height of the left side: text reading 'Calories: 0 kcal' with a hollow circle icon, text reading 'Sugar: 0g' with a single green leaf icon, and an ingredient description reading 'Ingredients: Carbonated mineral water, natural lemon essence.'
