Our method
How we grade evidence
Nutrition advice is only as good as the evidence behind it — and most apps never show you that evidence at all. Fawna does. Every health claim carries a grade, so you always know how solid the science is before you act on it.
The three grades
Strong
Robust, consistent research — well-established science you can rely on. Example: energy needs rise by about 340 kcal a day in the second trimester of pregnancy.
Moderate
Promising but less settled — supported by good evidence, with some open questions. Example: higher fibre and protein supporting insulin sensitivity in PCOS.
Early
Worth watching, not acting on alone — emerging research that isn’t settled yet. We flag it honestly rather than overpromise.
The filled-pip count carries the meaning — not just colour — so the grade reads the same for everyone, including people with colour-vision differences.
Grounded in primary sources
Our nutrition content is built on primary sources and peer-reviewed research. We draw on bodies like ACOG, RCOG, NICE, the Institute of Medicine, the British Menopause Society, and journals including The Lancet and the American Journal of Clinical Nutrition — and every claim links to its source so you can check it for yourself.
What we won’t do
- We don’t show weight or BMI, and we never set weight-loss goals.
- We don’t inflate targets on weak evidence — if your cycle doesn’t change your calorie needs, we say so.
- We don’t market features that aren’t ready. Trends are information, not a verdict.
