Yuuk · beta waitlist

Do you know what you're eating?

Yuuk breaks every ingredient into three layers — what it is, what it does inside your body, and why it's really there — so you can see exactly how modern food additives affect your energy, gut health, and long-term wellbeing. Built on independent food science research, not marketing claims.

Spaces are strictly limited to ensure high-touch support for early members.

The problem

What Your Grocery List and Restaurant Menu Isn't Telling You

The hidden additive stack
No single ingredient tells the whole story. Whether it's a packaged snack or a restaurant entrée, products quietly stack synthetic additives — preservatives, dyes, emulsifiers — whose combined effect on your body is almost never disclosed on a label or a menu.
The inflammation trap
Grocery staples and go-to restaurant orders alike are driving silent metabolic stress — one of the quiet forces behind today's chronic illness landscape.
The personalization deficit
Generic diet advice ignores how your specific physiology reacts to specific ingredients — whether they're printed on a nutrition label or hidden in a restaurant recipe you'll never see.

The method

Built on ingredient science, not guesswork.

We didn't start with an app idea — we started with the ingredient list. Yuuk is built on independent food science research using a proprietary three-layer framework applied to every product we score. A built-in Critical Override flags compound harm even when a single score wouldn't catch it. That research has already scored 95+ real products, from grocery staples to restaurant menu items at chains most apps never touch. That analysis is what the Yuuk website beta puts in your hands first — searchable and ready to use — with the full mobile app following after.

Layer 01
What it is
Plain identification of every ingredient on the label — no jargon, no guessing.
Layer 02
What it does in your body
The mechanism. How it actually interacts with your gut, hormones, and long-term health — the layer most food apps skip entirely.
Layer 03
Why manufacturers use it
The industry incentive — cost, shelf life, texture — so you can see who the ingredient is really serving.

The science

Diets high in ultra-processed foods have been linked to higher rates of obesity, metabolic dysfunction, and chronic disease risk — even when researchers account for calories, sugar, and fat. Growing research points to the processing itself, not just nutritional content, as a meaningful piece of the puzzle.
