If you are trying to cut back on seed oils, the hard part is reading tiny ingredient lists in the aisle. Yuzu makes it a barcode scan: every seed oil and palm oil gets a red-dot advisory, so you see them at a glance instead of squinting at the fine print.
How the seed oil checker works
Scan a barcode and Yuzu reads the ingredient list, then marks each ingredient with a colour dot: red, amber or green. Seed oils and palm oil carry a red dot as an advisory, so oils like sunflower, rapeseed (canola), soybean, corn and grapeseed stand out immediately. Tap any ingredient and you get a plain-English explanation, and for additives the EFSA source behind the rating.
What the red dot on a seed oil means
The red dot is an advisory, put there to make the oil visible for people who choose to avoid it. To be honest about how the score works: the seed-oil and palm-oil advisory does not, on its own, drag down the 0–100 number, because the fat in the oil is already counted once through the nutrition part of the score (saturated fat and so on). We flag the oils so you can spot them; we do not double-penalise the same gram of fat.
More than just oils
The same scan explains the rest of the label too. You get a 0–100 health score that reflects sugar, salt and saturated fat, and every E-number is explained in plain English with its EFSA source. Additive risk is kept separate from bulk-nutrient quantity, so sugar is not flagged as if it were a hazardous chemical. How Yuzu works.

It is there to make the oils visible, not to double-count them.
