**Approach: Macro science, with Palette C (natural).**

Extreme close-up, shot from a low 30-degree angle, of finely sifted matcha powder in a shallow matte ceramic bowl. A bamboo whisk's tines have just lifted from the surface, leaving a swirl of vivid green foam with a few tiny bubbles. Individual powder grains and the soft ridges of the foam are sharp in the foreground, and the background falls into a creamy blur. Soft side light from a window at left picks out the velvety texture and a faint sheen on the bubbles. The palette is grassy greens, with a worn wooden table in warm brown and a hint of pale daylight. The mood is calm and focused, with a clean, airy, natural feel. The green is the vivid, near-electric tone of fresh matcha. No text, no logos.

Matcha nadmašuje obični kofein za rad pod stresom, studija otkriva

BY NOVA CHEN · 19. lis 2026.

Kofein se tradicionalno povezuje s našom jutarnjom budnošću, ali randomizirano ispitivanje na sredovječnim i starijim Japancima sugerira da matcha pruža dodatne benefite. Jedna doza kofeina poboljšala je pažnju, dok je samo kontinuirani dnevni unos matcha povećao radni učinak na stresnom testu aritmetike. Autori ga povezuju s kombinacijom kofeina i aminokiselina, osobito L‑teanina. Studija ima ograničenja – laboratorijski stres, jedinstvenu populaciju i nedostatak grane s izoliranim teaninom – pa su zaključci podložni rezerve. Evo što to znači za matchu naspram kave, svakodnevne navike naspram jedinstvenih doza i tko bi mogao imati najviše koristi.
