PCOS food scanner grades: what an A–D result can and cannot tell you

Pea's A–D grade is an AI-generated estimate about a meal's likely blood-sugar impact. It is not a measurement of your glucose, a diagnosis of insulin resistance or a judgment about you. A phone camera cannot tell what is happening in your bloodstream.

What goes into the result?

Pea interprets the food information you provide and returns a grade, an explanation and a suggested adjustment. A photo can provide clues, but it may miss ingredients, confuse similar-looking foods or estimate a portion incorrectly. Typing more detail can help clarify what is in the meal.

Consider a bowl of soup: the photo alone may not reveal whether it contains lentils, noodles, cream or all three. A useful review asks whether Pea recognised the meal before asking whether the grade makes sense.

Three checks before using a grade

1. Ingredients: correct anything the scanner missed or added.
2. Portion: make sure the described amount resembles what you ate.
3. Explanation: read the reasoning and suggested pairing, rather than treating the letter as a rule.

Why the same food does not mean the same result for everyone

The app is not observing your individual glucose response. It cannot establish how you responded to this meal today. If your clinician has asked you to measure glucose, follow their monitoring plan; a photo grade is not a substitute.

Use the suggestion without chasing a score

A meal is more than a letter. Preferences, culture, convenience, enjoyment, allergies and the advice you have received all matter. You can take a pairing idea from Pea without trying to make every logged meal earn the same grade.

If a suggestion seems unsuitable, leave it. AI can be wrong. Pea is intended to support everyday food choices and record keeping, not prescribe treatment, identify allergies or decide whether a food is medically safe for you.

Where Pea fits

Use the scan as a starting point for a practical food decision. Keep your own observations in check-ins, and use a visit summary when you want to discuss them. The record belongs in a conversation, not in a claim that a specific meal caused a symptom.
